[0030] In this embodiment, when the waterproof and high temperature resistant electric cable is used, Figures 1 to 3As shown, the outside of the wire 6 is connected with an insulating layer 10, and the insulating layer 10 can be made of a material with good insulation effect, such as polyvinyl chloride, cross-linked polyethylene, polyethylene, acrylic rubber, etc. The above are all materials with good insulation performance, which can effectively improve the insulation performance of the wire 6 and better protect the wire 6.
