I. From the Perspective of the Product Itself
(I) Specification Parameters
This professional - grade
Copper Ground Wire has rigorous and detailed settings in terms of specification parameters, fully meeting the power safety requirements in different scenarios.
Its core specifications include 25mm², 50mm², and 95mm². These three specifications are precisely designed based on different current - carrying requirements and application scenarios. For the 25mm² ground wire, the cross - sectional area is 25 square millimeters, the diameter of a single
Copper Wire is between 0.1 - 0.2mm, the overall diameter of the cable is about 5 - 6mm, and the weight per meter is about 0.23kg. The 50mm² ground wire has a cross - sectional area of 50 square millimeters, with a single copper wire diameter ranging from 0.2 - 0.25mm, an overall cable diameter of approximately 7 - 8mm, and a weight per meter of about 0.45kg. The 95mm² ground wire has a cross - sectional area of 95 square millimeters, a single copper wire diameter of 0.25 - 0.3mm, an overall cable diameter of about 10 - 11mm, and a weight per meter of about 0.86kg.
In terms of conductivity, all three specifications of ground wires perform excellently, with a conductivity of ≥98%. This means that during current transmission, energy loss is extremely low, and current can be quickly conducted into the ground. In terms of temperature resistance, they can work normally in an ambient temperature range of - 40℃ to 70℃, and can maintain stable performance even in extremely cold or hot areas. In terms of insulation resistance, it is ≥1000MΩ under normal conditions, ensuring good insulation effect and avoiding safety hazards such as electric leakage. In addition, they also have strong voltage resistance, being able to withstand 2500V AC voltage for 1 minute without breakdown, further ensuring safety during use.
(II) Characteristic Uses
This copper ground wire has a wide range of characteristic uses, covering multiple fields, and providing reliable protection for power safety in different scenarios.
The 25mm² ground wire, due to its relatively moderate current - carrying capacity, is suitable for grounding protection of small power distribution equipment, household circuits, and weak current systems. In households, it can be used for lightning protection grounding of household appliances such as refrigerators, air conditioners, and TVs. When struck by lightning, it can quickly conduct the current generated by lightning into the ground to avoid damage to the appliances. In the communication field, it can be applied to lightning protection grounding of communication base stations, ensuring the normal operation of base station equipment and reducing communication interruptions caused by lightning strikes.
The 50mm² ground wire has a strong current - carrying capacity and is widely used for fault grounding of medium - sized industrial equipment, factory power distribution systems, and building power main lines. In medium - sized industrial equipment, such as some small and medium - sized machine tools and production line equipment, this specification of ground wire can timely conduct fault current into the ground when the equipment fails, preventing the equipment from being damaged due to overcurrent and ensuring the safety of operators. In factory power distribution systems and building power main lines, it can meet the safety protection needs under medium current loads, ensuring the stable operation of the power system.
The 95mm² ground wire, as a high - current carrying model, is mainly used in key power facilities such as high - voltage substations, large industrial plants, and
Power Stations. Once a lightning strike or line short circuit occurs in the power systems of these places, huge pulse currents or fault currents will be generated. The 95mm² ground wire can effectively conduct these currents, avoiding equipment burnout due to overcurrent and reducing the risk of casualties. For example, in high - voltage substations, it is an important part to ensure the safe operation of the substation and can provide strong support for the stability of the entire power transmission network.
(III) Material and Style
In terms of materials, this copper ground wire uses high - purity electrolytic copper as the conductor, which has many advantages. High - purity electrolytic copper has extremely high purity and extremely low impurity content, which enables it to have excellent conductivity and efficiently transmit current. At the same time, it also has excellent corrosion resistance and oxidation resistance, and can be used for a long time in complex environments such as outdoors, humidity, and high temperatures without being easily corroded or oxidized, greatly extending the service life of the ground wire.
The outer insulating sheath is made of weather - resistant PVC material, which has various excellent properties. It is acid and alkali resistant, and can maintain stable performance in an environment with acid and alkali corrosion; it is UV resistant, and will not age and crack due to UV radiation even when exposed to sunlight outdoors for a long time; it is resistant to mechanical damage, and can effectively resist the damage to the internal
Copper Conductor caused by external mechanical forces such as collision and friction, thereby protecting the internal copper conductor from external environmental erosion.
In terms of style, the ground wire adopts the internationally universal green - yellow 双色 identification, which is of great significance. The green - yellow 双色 is an internationally recognized ground wire identification, which can clearly distinguish the ground wire from other cables. During construction, construction personnel can quickly identify it, reducing the risk of misoperation and improving the safety and efficiency of construction. In addition, the multi - strand stranded structure design not only ensures the overall
Flexibility, but also increases the surface area of the conductor, improving heat dissipation efficiency.
(IV) Production Process
The production process of this copper ground wire is exquisite, and every link is strictly controlled to ensure the high quality of the product.
Firstly, in the copper processing process, after selecting high - purity electrolytic copper, a series of processing steps are carried out to draw the copper into single - strand copper wires with the required diameter. During the drawing process, the drawing force and speed are precisely controlled to ensure that the diameter of the single - strand copper wire is within the specified range with minimal error, which lays a good foundation for the subsequent stranding process.
Next is the multi - strand stranding process, in which multiple single - strand copper wires are stranded according to a specific stranding method. During the stranding process, the lay length and tension of the stranding are strictly controlled to make the copper wires closely combined to form a whole. This stranding process not only ensures the flexibility of the ground wire, facilitating construction in narrow spaces or complex wiring environments, but also improves heat dissipation efficiency by increasing the conductor surface area, avoiding overheating caused by short - term large current passing through.
Then is the extrusion process of the insulating sheath. The
Stranded Copper Conductor is put into an extruder, and the PVC material is uniformly wrapped around the outer layer of the copper conductor through the extruder to form the insulating sheath. During the extrusion process, the extrusion temperature, speed, and pressure are precisely controlled to ensure that the thickness of the insulating sheath is uniform, closely combined with the copper conductor, and free of defects such as bubbles and cracks. This process ensures the good performance of the insulating sheath, which can effectively protect the internal copper conductor.
Finally, each batch of products must undergo strict quality inspection processes, including multiple inspections such as conductivity testing, high - voltage resistance testing, and mechanical strength testing. Conductivity testing ensures that the conductivity of the ground wire meets the requirements; high - voltage resistance testing verifies its insulation performance in high - voltage environments; mechanical strength testing checks its mechanical properties such as tensile and bending resistance. Only products that pass all tests can leave the factory to ensure reliability in extreme situations.
II. From the Perspective of General Product Information
(I) Packaging
In order to ensure that the ground wire is not damaged during transportation and storage, the product adopts a scientific and reasonable packaging method.
For a single ground wire with a length of 100 meters, it is packaged with a sealed plastic reel. The plastic reel has a certain degree of hardness and toughness, which can well protect the ground wire from external extrusion and collision. Both ends of the reel are equipped with baffles to prevent the ground wire from loosening and sliding off the reel. The outside of the reel is wrapped with a layer of moisture - proof plastic film, which can effectively prevent the ground wire from getting damp, especially suitable for storage and transportation in humid environments.
For batch transportation of ground wires, strong wooden cases are used for packaging. The wooden cases are made of high - quality wood, with strong bearing capacity and impact resistance. Inside the wooden case, a layer of buffer material, such as foam board or pearl cotton, is first laid, and then the plastic reels wrapped with ground wires are neatly placed in the wooden case. The reels are separated by buffer materials to avoid mutual collision. The outside of the wooden case is reinforced with steel belts to ensure that the wooden case will not fall apart during transportation.
