It can be used for insulation of the power cable joint with Voltage standard from 600V-35kV.

Excellent physics and electric performance:

water-resistant seal without heat, torches or adhesives. Simply unwind the core to install

excellent elasticity,High tensile strength and ultimate elongation.

An open-ended rubber sleeves which are factory expanded and assembled onto removable plastic cores. The core is removed after the tube has been positioned for installation over an inline connection, coupling cable or termination, allowing the tube to shrink and form a water-resistant seal.Can be instead some silicone materials cold shrink tubing in some special deprtment.
