Radiation crosslinked heat shrinkable busbar protection tube 

 Radiation crosslinked heat shrinkable busbar protection tube is often used in high and low voltage electrical substations and low voltage switch cabinets and other products in copper and aluminum bus bar insulation protection, the product with a shrinking band, bus bar boxes, boxes and other ancillary products arrester protection . Flame retardant, high pressure characteristics, divided into MPG1, MPG10, MPG35 are 0.6/1KV, 6/10KV, 26/35KV three categories. Other color and size specifications can be customized according to customer requirements
