(I) Specification Parameters
SWA
Armoured Power Cables cover various specifications such as 25mm², 35mm², 50mm², and 70mm², all of which are 4 - core low - voltage
Armoured Cables. This series of specifications is set to meet the load requirements in different power transmission scenarios.
In terms of conductor specifications, 25mm² cables are suitable for small - power power transmission, such as internal power distribution in small shops; 35mm² cables can handle medium loads, like branch power supply in ordinary residential communities; 50mm² cables can meet the power demand of large - power equipment, such as some production lines in small and medium - sized factories;
70mm² Cables are applicable to high - load scenarios, such as the main power distribution lines in large shopping malls. The 4 - core design includes three phase wires and one neutral wire, which meets the requirements of the three - phase four - wire system in low - voltage power distribution systems and can achieve stable power distribution.
This series of cables uses XLPE (cross - linked polyethylene) insulation. The XLPE insulation layer has excellent insulation performance with high insulation resistance, which can effectively prevent current leakage and ensure the safety of power transmission. At the same time, the XLPE insulation layer has good temperature resistance. The long - term allowable operating temperature can reach 90°C, and it can withstand higher temperatures during short - term overload, which enables the cable to operate stably when the power load fluctuates.
The SWA (steel wire armouring) layer provides reliable mechanical protection for the cable. The diameter and winding density of the armoured steel wire depend on the cable specification. The larger the specification of the cable, the higher the strength of the armoured layer to withstand greater external pressure. Whether it is the pressure of the soil during underground laying or the external impact that may be encountered during overhead laying, the armoured layer can play an effective protective role.
There are two types of sheaths available: PVC (polyvinyl chloride) and LSZH (low smoke zero halogen).
PVC Sheaths have good corrosion resistance and wear resistance, and the cost is relatively low; LSZH sheaths do not release a large amount of toxic and harmful gases and smoke when burned, so they have higher safety and are suitable for places with high fire safety requirements, such as hospitals and subways.
The rated voltage of the cable is low - voltage level, which meets the relevant low - voltage power distribution standards and can be well adapted to low - voltage power distribution equipment to ensure the stability of power transmission. The outer diameters of cables with different specifications are also different. The larger the specification, the larger the outer diameter, but they are all reasonably designed to facilitate installation in different laying environments.
SWA armoured
Power Cables are widely used in many scenarios due to their various specifications and excellent performance.
In commercial places, 25mm² and 35mm² cables are commonly used. In small supermarkets, convenience stores and other places, there are relatively few electrical equipment, and 25mm² cables can meet their daily power supply needs; 35mm² cables are suitable for store power distribution and public area lighting in medium - sized shopping malls. The SWA armoured layer can protect the cable from accidental collisions that may be caused by people walking and goods handling, and the XLPE insulation layer ensures the stability of power transmission and reduces the risk of power outages.
In the field of residential life, 35mm² and 50mm² cables are widely used. 35mm² cables are commonly used for building distribution branches in ordinary residential communities, which can meet the simultaneous use of various electrical appliances in residents' homes; some large residential communities will choose 50mm² cables for their main lines to cope with the total power load of more residents. Cables with PVC sheaths are more common in ordinary communities, while LSZH
Sheath Cables are more popular in high - end communities with higher requirements for environmental protection and safety.
In industrial production scenarios, 50mm² and 70mm² cables play an important role. For the power supply lines of production equipment in small and medium - sized factories, cables of corresponding specifications can be selected according to the power of the equipment. For example, 50mm² cables can be used for equipment power supply in some assembly workshops, while 70mm² cables can provide more stable power support for high - power stamping equipment. The SWA armoured layer can resist external impacts that may be caused by mechanical operations in the factory, ensuring the continuous progress of production.
In terms of public facilities, this series of cables also performs well. Places such as hospitals and schools have high requirements for the safety and stability of cables. For ward power distribution and medical equipment power supply in hospitals, cables of appropriate specifications can be selected according to the load, and LSZH sheath cables are preferred to cope with emergencies such as possible fires; for power distribution lines in school teaching buildings and office buildings, cables of corresponding specifications can also be selected according to actual needs.
The material selection and style design of SWA armoured
Power Cables are closely related to their performance and use, and the application of each material is carefully considered.
The conductor is made of high - purity copper. Copper has excellent conductivity and low resistivity, which can reduce energy loss during power transmission and improve transmission efficiency. The surface of the high - purity
Copper Conductor is smooth and free of impurities, which can be closely combined with the XLPE insulation layer to avoid local overheating caused by poor contact.
The XLPE insulation layer is the core insulation part of the cable. It forms a three - dimensional network structure through a cross - linking process. Compared with traditional polyvinyl chloride
Insulation Materials, its mechanical strength, aging resistance and chemical corrosion resistance are significantly improved. During long - term use, the XLPE insulation layer is not easy to crack, harden and other problems, and can maintain stable insulation performance, extending the service life of the cable.
The SWA armoured layer is composed of high - strength steel wires. The steel wires are galvanized, which has good corrosion resistance and can prevent rust and damage in humid, dusty and other environments. The steel wires are spirally wound around the outside of the insulation layer, and the winding density is precisely controlled according to the cable specification, which not only ensures the strength of the armoured layer, but also does not excessively increase the hardness of the cable, facilitating laying and installation.
The two types of sheaths have their own advantages. PVC sheaths have good oil resistance, chemical corrosion resistance and wear resistance, can adapt to a variety of complex environments, and have mature processing technology and relatively low cost; LSZH sheaths are made of halogen - free materials, have good flame retardancy, and release little smoke and low toxicity when burned, which can buy time for personnel evacuation and rescue, and are especially suitable for use in confined spaces and crowded places.
In terms of style, this series of cables has a circular structure, which makes the force on the cable more uniform. When subjected to external pressure, the force can be dispersed to the entire section, reducing the risk of local damage. At the same time, the circular structure is convenient for cable winding, transportation and storage, and can better adapt to various laying pipes and trunking, improving construction efficiency.
(IV) Production Process
The production process of SWA
Armoured Power Cables is rigorous and meticulous, with strict quality control standards in each link from raw material processing to finished product inspection.
The production of the conductor is the first step. High - purity copper rods are selected and drawn into
Copper Wires of the required diameter through a wire drawing process. During the wire drawing process, the wire drawing speed and die precision must be strictly controlled to ensure that the diameter of the copper wire is uniform and the surface is smooth. Then, multiple copper wires are stranded in a specific way to form a conductor. During stranding, the roundness and tightness of the conductor must be ensured to reduce energy loss during transmission.
The extrusion of the XLPE insulation layer is one of the key processes. First, the XLPE particles are dried to remove moisture in the particles to avoid defects such as bubbles in the insulation layer. The dried XLPE particles are sent to the extruder and melted into a fluid state at high temperature, and then uniformly wrapped around the outside of the conductor through an extrusion die to form an insulation layer. During the extrusion process, the temperature, pressure and speed must be accurately controlled to ensure that the insulation layer has a uniform thickness and a smooth surface. After extrusion, the insulation layer is cross - linked, and the XLPE molecules are cross - linked by heating to form a stable structure.
The production of the SWA armoured layer requires winding steel wires around the outside of the insulation layer through an armouring machine. During the winding process, the tension and winding angle of the steel wires must be controlled to ensure that the steel wires are arranged neatly and tightly, and the lap between adjacent steel wires is reasonable to ensure the overall strength of the armoured layer. After winding, the armoured layer must be inspected to ensure that there are no broken wires, looseness and other problems.
The extrusion of the sheath adjusts the process parameters according to different materials. For PVC sheaths, PVC particles are added to the extruder, heated and melted, and then wrapped around the armoured layer through a die; for LSZH sheaths, special LSZH materials are used, and the temperature must be controlled during the extrusion process to avoid material decomposition. Both sheaths are cooled and shaped after extrusion to ensure that the sheath has stable dimensions, a flat surface and is closely combined with the armoured layer.
In the finished product inspection link, comprehensive tests are carried out on the electrical conductivity, insulation performance and mechanical properties of the cable. The conductivity of the conductor is checked through DC resistance testing, the insulation effect of the insulation layer is verified through insulation resistance testing and voltage withstand testing, and the mechanical strength of the cable is tested through tensile and bending tests. Only cables with all indicators meeting the standards can leave the factory.
II. General Product Information
(I) Packaging
The packaging design of SWA armoured power cables takes protecting the integrity of the cables during storage and transportation as the primary goal, while taking into account the convenience of packaging and the clarity of identification.
For coiled cables, wooden or metal reels are used for packaging. The diameter and strength of the reel are determined according to the specification and length of the cable to ensure that it can stably carry the weight of the cable. The cable is neatly wound on the reel, and appropriate tension is maintained during winding to avoid surface damage caused by loose, twisted or mutual friction of the cable. Both sides of the reel are equipped with baffles, and the height of the baffles is higher than the winding height of the cable to prevent the cable from slipping during transportation and storage.
The outside of the reel is tightly wrapped with a plastic film to form a moisture - proof and dust - proof barrier, preventing the cable from getting damp and contaminated with dust. For products with high storage environment requirements such as LSZH sheath cables, a layer of moisture - proof paper is covered outside the plastic film to further improve the moisture - proof effect.
Clear labels are pasted on the baffles of the reel. The labels indicate the product name, specification (such as 25mm² 4 - core
Swa Armoured Cable), sheath material (PVC or LSZH), length, production batch number, production date, implementation standard, manufacturer name and contact information, etc. At the same time, warning signs such as "Moisture - proof", "Sun - proof" and "Do not press heavily" are also marked on the labels to remind relevant personnel to pay attention to protection during handling and storage.
For small - batch or short - length cables, solid cartons are used for packaging. Buffering materials such as foam boards and bubble films are placed inside the cartons to prevent the cables from being damaged due to collision during transportation. Product - related information and warning signs are also marked on the outside of the cartons.
(II) Transportation
The transportation of SWA armoured power cables must follow strict specifications to ensure that the cables are not damaged during transportation.
The transportation method is selected according to factors such as transportation distance and cable quantity. For long - distance transportation with a large quantity, railway transportation or road freight is usually used. For railway transportation, the reels are placed stably in the freight carriage, and the reels are fixed at the bottom of the carriage with steel wire ropes or special fastening belts to prevent sliding or toppling during transportation. Leave an appropriate gap between the reels to avoid mutual collision. For road freight, a truck with sufficient load - bearing capacity is selected, and the carriage must be flat, clean and free of sharp debris. The fixing method of the cable reels is the same as that of railway transportation.
For short - distance transportation or small - batch transportation, logistics vehicles can be used. When loading and unloading cables, special hoisting equipment is used. The hoisting point is selected at the central axis of the reel. Hoisting directly from the side of the reel or the cable coil is strictly prohibited to prevent reel deformation or cable damage.
The following matters should be noted during transportation: Cables should avoid open - air transportation. If it is unavoidable, they must be covered with waterproof canvas to prevent sun and rain; Keep away from fire sources, heat sources and corrosive substances to avoid damage to the insulation layer and sheath of the cable; The transport vehicle should drive smoothly during driving, avoiding violent operations such as sudden braking and sharp turns to reduce the impact on the cable; During transportation, regularly check the fixing of the cable and the integrity of the packaging, and handle problems in a timely manner.
After arriving at the destination, it is necessary to check the packaging and appearance of the cable with the receiver, and go through the handover procedures only after confirming that there is no damage. If there is packaging damage or signs of cable damage, it should be recorded in time and communicated with the transporter and the shipper for handling.
(III) Delivery
The delivery process of SWA armoured power cables focuses on efficiency and accuracy to ensure that customers can receive products that meet the requirements on time.
After the customer places an order, the sales department promptly enters the order information into the system and transmits it to the warehouse and production department. After receiving the order, the warehouse immediately checks the inventory. For spot products, after confirming that the specifications, quantity, sheath material and other information are consistent with the order, it arranges for goods preparation; for customized products, the production department organizes production according to the order requirements and notifies the warehouse for storage after production is completed.
In the process of goods preparation, warehouse personnel conduct strict inspections on the cables, including whether the appearance is intact, whether the label information is accurate, and whether the packaging meets the standards. At the same time, sort out relevant product materials, such as product certificates, test reports and user manuals, and prepare them for delivery together with the cables.
Before delivery, the warehouse contacts the transport company, determines the transport method and transport vehicle according to the order situation, and signs a transport agreement with the transport company, specifying the transport time, transport route, cargo storage responsibility and other matters. For urgent orders, priority is given to arranging delivery, and transport resources are coordinated to ensure delivery within the agreed time.
After the goods are shipped, the warehouse promptly feeds back the logistics information (such as the name of the transport company, waybill number, contact information, etc.) to the customer, facilitating the customer to track the transport status of the goods. At the same time, the warehouse retains delivery records, including delivery notes and logistics documents, for future reference. If problems such as delayed delivery or damage to the goods occur during transportation, the warehouse will promptly communicate and coordinate with the transport company and inform the customer of the progress of the handling.
