Cold tolerant, corrosion and humidity resistant and uvioresistant power cable

The utility model discloses a cold tolerant, corrosion and humidity resistant and uvioresistant power cable which comprises cable cores comprising conductors and insulating layers covered outside the conductors. A packing layer and an outer sheath are arranged outside the cable cores arranged in parallel. The power cable is characterized in that a water-proof belt layer, a humidity resistant isolating layer and a non woven fabric belt layer are arranged between the packing layer and the outer sheath in sequence. The power cable has strong salt and caustic corrosion resistance and strong ultraviolet irradiation resistance performance, fiberglass ropes with stable mechanical and chemical performances are adopted for the packing layer, water-proof polyester yarns and polyester belts with high expansion ratio are adopted for the belt layers, plastic-aluminum composite belts is adopted for the humidity resistant isolating layer after longitudinal wrapping and fusion welding, weather and corrosion resistance fluorocarbon silicone rubber is adopted for the outer sheath, therefore, the product can be widely used in environments such as arcticalpine plateau zones and inland salt and alkali lakes and beaches.
