1.Product Introduction
The Bus-bar Box or Bus-bar cover is made of radiation crosslinked polyolefin material with excellent physical, chemical and electrical properties. It is the insulation treatment material where the bus-bar is connected. The Bus-bar Box is a kind of electric power insulation protective cover, usually suitable for high and low voltage substation and high and low voltage switchgear, etc. Polyethylene protection for transformer, bus-bar, cable and other incoming and outgoing lines in electric power products. The product has excellent insulation, aging resistance, tear resistance, uv resistance and other properties. The unique buckle structure of the product is easy to disassemble and reuse, and solves the defect that the bus bar cross connection cannot be completely covered by conventional high pressure heat shrinkable tube.
