Bus Bar Insulating Shrouds Polyolefin
Busboot – Polyolefin is flexible electrical insulating boot / shroud for busbar and switchgear connections upto 36KV. These pliable boots can be installed, removed or replaced in few minutes. Made from high quality Cross-linked Polyolefin material to provide excellent electrical insulation and to withstand higher operating temperature continuously
It provides reduction in air clearance, which helps designing compact panels; thereby reduces the material costs by saving in busbar lengths, sheet metal components, etc.
Features and Benefits
- Reduces BusBar Clearance.
- High Di-electric Strength.
- Halogen free.
- Suitable for insulating busbar joint(tees, elbows, etc.)
- Easy to Install or Remove as often as required.
- Highly resistant to UV rays and ozone.
- suitable for any shapes or connections.
- Prevents Busbar from chemical corrosion effected by strong acid, alkali, salt, etc.
