Savings in Switchgear Component Cost > Investment in Busboot
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.
