This data sheet covers the requirements for heat shrinkable heavy wall insulating tubes (MVIT) whose dimension will shrink to a predetermined size upon the application of heat above 125° C. Color of the MVIT is red. The MVIT provides a high level of insulation.MVIT is normally used as an integral part of cable joints up to 36kV for protection & insulation. MVIT provides excellent insulating properties and reinstates the original insulation level of the cable.
