Introduction        
Semi-rigid polyolefin material, inner layer of semi-conductive heat shrinkable material, outer layer of insulating heat shrinkable material, double-layer composite heat shrinkable tube. It is suitable for tubular busbars, used in conjunction with semi-conductive heat-shrinkable tubes and insulating outer sheaths. The design of withdrawing screens on the tubular busbars can effectively distribute electrical stress and reduce partial discharge. Applied to voltage levels of 1~36kV, in two application scenarios of 10kV and 35kV, 3-layer and 7-layer GM-DI tube bus with internal semiconducting and external insulation heat shrinkable tube are usually used respectively, which can meet the requirements of tube bus insulation design .
