Heat Shrinkable Sleeves provide insulation enhancement to bus-bar systems up to 36kv and protect them against flashover and accidental induced discharge. The use of bus-bar tubing allows equipment designers the freedom to reduce air spacing between bus-bar, such as in manufacture of switchgear cabinets where space is at a premium.Heat Shrinkable tubes are manufactured from high quality non-tracking, non-halogen, cross-linked based polymer which has excellent performance in high voltage environments & reduces the noxious and corrosive effects in fire situation.
Features
- Reduce Bus-bar clearance.
- Solve the problem of insulation among Bus-bar in Bus Duct.
- Halogen free, flame retardant.
- High dielectric strength.
- High resistance to tracking, aging & corrosion.
- It can be offered in constant length.
