(III) Material and Style
The 2000 Volt Copper Tray Cable Rhw-2/PVC Shielded Power Cable fully combines performance requirements and actual application scenarios in material selection and style design, making it have excellent comprehensive performance.
The conductor is made of high-purity copper, which in addition to having excellent conductivity, also has good ductility and
Flexibility. This allows the cable to be easily bent and stretched during laying, adapting to different installation paths, and also reduces the risk of conductor breakage due to excessive bending.
The insulation layer is made of special materials that meet the RHW-2 standard. This material has excellent temperature resistance and moisture resistance. Its molecular structure is stable, and it is not easy to age and crack in high and low temperature environments, and can maintain good insulation performance for a long time. Moreover, the insulating material also has certain chemical corrosion resistance, which can resist the erosion of some common chemical substances.
The outer PVC shielding layer is made of polyvinyl chloride material, which has good plasticity and stability. The PVC shielding layer can not only effectively shield electromagnetic interference, but also has certain mechanical strength, which can protect the internal conductors and insulation layers of the cable from external extrusion, collision and wear. At the same time, PVC material also has certain flame retardant performance, which can delay the spread of fire when encountering an open flame, improving the safety of the cable.
The cable is available in single-core or
Multi-Core styles. In the multi-core style, each core conductor is independent, wrapped in an insulation layer respectively, and then jointly wrapped by a PVC shielding layer. This structural design ensures that there is no mutual interference between each core conductor, and they can transmit different power signals respectively, improving the practicability and flexibility of the cable. The appearance color of the cable is usually black. The black PVC shielding layer not only has good weather resistance, can adapt to outdoor sun and rain, but also can visually blend with the surrounding environment, reducing a sense of abruptness.
(IV) Production Process
The production process of the 2000 Volt Copper Tray Cable Rhw-2/PVC Shielded Power Cable strictly follows high-standard process requirements. Every link from raw material processing to finished product inspection is carefully controlled to ensure the quality and performance of the product.
In the conductor manufacturing link, first, high-purity copper materials are smelted and cast into copper rods. Then, the copper rod is drawn into a
Copper Wire of the required diameter through a wire drawing process. During the wire drawing process, it is necessary to accurately control the drawing speed and temperature to ensure that the copper wire has a uniform diameter and a smooth surface. After wire drawing, the copper wire is annealed to eliminate internal stress and improve its flexibility and conductivity. For
Multi-Core Cables, it is also necessary to strand multiple copper wires together to form a conductor bundle. During the stranding process, it is necessary to ensure that the stranding pitch is uniform to ensure the stable performance of the conductor.
The insulation layer is made by extrusion molding process. The insulating material that meets the RHW-2 standard is heated and melted, and then extruded and coated on the outside of the conductor through an extruder to form a uniform insulation layer. During the extrusion process, it is necessary to strictly control the extrusion temperature, speed and pressure to ensure that the insulation layer has a uniform thickness, is closely combined with the conductor, and has no defects such as bubbles and impurities. After extrusion, the insulation layer is cured to make its performance more stable.
The production of the PVC shielding layer also adopts the extrusion process. The PVC material is heated and melted in the extruder, and then extruded and coated on the outside of the cable core that has been covered with the insulation layer to form a shielding layer. During the extrusion process, it is necessary to control the extrusion parameters to ensure that the shielding layer has a uniform thickness, a smooth surface, and is closely attached to the insulation layer. At the same time, due to the characteristics of PVC materials, attention should be paid to the control of extrusion temperature to avoid material decomposition affecting the performance of the shielding layer.
Throughout the production process, multiple quality inspection procedures are also required. The diameter, resistance, tensile strength and other parameters of the conductor are tested; the thickness, insulation resistance, voltage resistance performance, etc., of the insulation layer are tested; the thickness, shielding effectiveness, wear resistance, etc., of the PVC shielding layer are inspected. In addition, sampling tests will be carried out on the overall performance of the cable, such as temperature resistance and moisture resistance, to ensure that each batch of cables meets relevant standards and requirements.
II. General Product Information

The packaging design of the 2000 Volt Copper Tray Cable Rhw-2/PVC Shielded Power Cable fully considers the characteristics of the product and the needs of transportation and storage, aiming to maximize the protection of the cable from damage during transportation and storage.
The cable is usually packaged in reels. The reels are made of high-strength wood or metal materials, which can bear the weight of the cable and the pressure during transportation. The size of the reel is customized according to the length and diameter of the cable to ensure that the cable can be neatly wound on the reel, avoiding cable distortion, deformation or damage to the insulation layer due to improper winding.
A layer of moisture-proof paper or plastic film is laid between the cable and the reel to prevent the cable from getting damp. For cables that need long-distance transportation or are stored in humid environments, a layer of waterproof cloth is also wrapped around the outside of the reel to further enhance moisture-proof and waterproof performance.
Relevant product information is clearly marked on the packaging, including product name, model specification, rated voltage, conductor cross-sectional area, length, weight, production date, batch number, execution standard, etc., to facilitate user identification and acceptance. At the same time, eye-catching warning signs such as "Handle with Care", "Moisture-Proof", "Sun-Proof", "No Stepping" are printed on the packaging to remind transportation and storage personnel to pay attention to relevant matters.
For small batches of cables, they can also be packaged in coils or bundles. When coiled, the cable is coiled on a plastic or metal disc; when bundled, the cable is tied firmly with high-strength ropes.
