Product Description

Dry Insulation Tubing Busbar
Triple Co-Extrusion (TCE) technology on Tubing Busbar Shielding-Insulating-Shielding, all three layers are extruded simultaneously.

1. Ensured uniform thickness of shield rubber. 
2. Non-clearance between the rubbers, and the copper tube, maximizing material physical and electrical property. 
3. Highest density of rubber shield under vacuum (production), free of air trap, lower partial discharge, higher electrical stability
