detailed description:

hardCopper stranded wire/bare copper wireThe copper rods used for raw materials are all produced using the 350000 ton SCR-7000 copper continuous casting and rolling production line of the US South Line, ensuring stable and guaranteed product quality.Hard copper stranded wire and bare copper wireThe single wire uses the most advanced high-speed continuous pulling and withdrawal copper drawing technology currently available in China. The entire process of copper stranded wire processing is controlled by a microcomputer, ensuring stable and reliable quality of the single wire. The performance of the hard copper stranded wire meets or exceeds national standards and EU electrical standards, ensuring safe and worry free use.

The hard copper stranded wire produced by Huawei Metal Materials Co., Ltd. adopts a high-speed cage twisting machine for untwisting and twisting. During the twisting process, a unique * * * * technology is used. The finished hard copper stranded wire is round, straight, tightly structured, and free of loose strands, which can facilitate various subsequent crimping and extrusion processes.

The commonly used copper stranded wire/bare copper stranded wire structures include 7 strands, 12 strands, 19 strands, 37 strands, 61 strands, etc., with a large cross-sectional area of up to 400mm ².

Hard copper stranded wire/Grounding copper stranded wire/Bare copper wire can be used in some extreme environments, such as humid, saline alkali, acidic soil, and chemical corrosive substances, and is usually used in electrified railwayscatenaryThe load-bearing cables, lightning protection grounding, power station grounding, signal towers, etc. can be used as grounding materials, down conductors, equipotential connections, and electrified railwayscatenaryCarrier cables and feeders. lightning protectionGrounding copper stranded wireWidely used in engineering fields with high lightning protection and grounding requirements, such as transmission and transformation power stations, power plants, communications, railways, municipal infrastructure, petroleum and petrochemical industries!
