Waterproof and ultraviolet-resistant special cable

The utility model discloses a waterproof and ultraviolet-resistant special cable, comprising a main core, and a belt-wrapping layer, a waterproof layer, an ethylene propylene insulation layer, an anti-ultraviolet layer and a low-smoke and halogen-free protection sleeve, with the latter five covering the main core in order. The middle of the internal part of the belt-wrapping layer is provided with an insulation panel, which evenly divides the belt-wrapping layer into two parts. The main core comprises four groups with each two groups being arranged at two sides of the insulation panel. Three drainage wires and a ground wire core are coated by the internal part of the ethylene propylene insulation layer. The waterproof and ultraviolet-resistant special cable is advantageous in that the cable is good in conductive performance, high temperature resistance, and insulation and water resistance; the core is mainly applied in fields like electric power, metallurgy, chemical petroleum; environment is protected with low smoke and no halogen, and the anti-dragging and anti-oxidation performance is good; the rate of ultraviolet ray shielding reaches to 96.6%.
