VMPG-10KV Heat Shrink Tube
VMPG High-voltage heat-shrinkable busbar sleeve is used for the insulation protection of busbar in 10KV, 20KV, 35KV substation power distribution cabinet and other occasions. It will not reduce the interception quantity of bus bar after installation. It has good flame retardant and insulating properties, providing a strong guarantee for the safe operation of the electric power system.
Features：Working Temperature -55℃~125℃; Shrinkage Temperature 100℃~130℃;
high strength, good elasticity, high flame retardant, good insulation, corrosion resistance and weather resistance.
