Product description

The product by pressing copper, aluminum (aluminum alloy) conductor, the inner shield and weathering type insulating materials and an outer shielding layer, the utility model has the advantages of simple structure, safe and reliable. It not only has excellent electrical properties of electric cables and overhead cable strong physical and mechanical properties. Due to the use of weather resistant insulating material, the product has excellent resistance to atmospheric aging, compared with bare wire, this product has the advantages of small installation space, high reliability, especially for high-rise buildings, jungle areas and the use of harsh climate regions.
