Environmentally friendly tinned copper-clad steel Tinned copper-clad steel uses steel wire as the core, and is formed by evenly depositing a copper layer and coating on the surface of the steel core. As a composite material, it has the comprehensive advantages of copper wire and steel wire. That is, the conductivity of copper wire and the strength of steel wire, and its strength is 3 to 4 times that of pure copper wire. The electrical conductivity is 3 to 5 times that of steel wire, and it is widely used as a new generation of communication lines and power transmission cables. Widely used in: 1. Output leads and connecting wires of electronic equipment 2. Electrified railway transmission cables 3. Connect communication lines and special electronic equipment 4. Cable TV cables, etc. We have strict quality, inspection and control systems to ensure the quality of our products. The spirit of pursuing high quality, high quality and customer satisfaction. Based on the principles of thoughtful service and reliable product quality.
