Heat Shrink Insulation Tube
Request a Quote
This heat shrink insulation tube is used to link and protect cables up to 42kV. The insulation tube is made of radiation crosslinked polyolefin and serves as a great protective cover. It begins shrinking when the environmental temperature reaches 90 ℃ and completes the process when the temperature reaches 130℃.
