25-80 yuan/m tinned copper conductor, tin plated copper flat steel is first coated with a layer of electrolytic copper, tin and then in the copper layer surface electroplating, the process to ensure the permanent between tin and copper layer and steel reinforced molecular combination, no physical defects such as cracks, ensure the conductor of oneness, when installing a laying effectively prevent become warped, craze, fall off wait for a circumstance; Tin plated copper flat steel can effectively prevent the oxidation reaction of copper layer because of the tin layer on the surface, which is beneficial to enhance the anti-corrosion performance of the ground conductor and increase the service life of the whole ground network. At the same time, because the surface color of tin-plated copper conductor is similar to that of ordinary galvanized material, it is not easy to be distinguished, and it is not easy to be considered as precious metal when used in outdoor, so it is not easy to be lost.
