The insulating heat shrink tubing is mainly used for insulation treatment of power cables, power busbars, etc., to insulate and wrap them to achieve the insulation isolation effect of live parts.

[0003] Reference publication number CN201277395Y is an environmentally friendly heat shrink tubing, which is characterized in that the heat shrink tubing is in the shape of a round tube with a hollow structure. The material of the heat shrink tubing is a polyolefin antioxidant material containing an antioxidant. The heat shrink tubing has excellent properties such as air oxidation resistance, acid and alkali resistance, copper corrosion resistance, and waterproofness. It can be widely used in electronics, automobiles, and aerospace fields, and is especially suitable for special protection such as automobile oil pipes and refrigeration copper-aluminum connecting pipes. According to the above, although the heat shrink tubing can be well applied, it is usually not convenient to monitor the current temperature of the heat shrink tubing.
