Savings in Switchgear Component Cost > Investment in Busboot
Bus boot 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 specially formulated Polyvinyl Chloride (PVC) material to provide excellent electrical insulation and to withstand higher operating temperature continuously.
Busboot provides reduction in air clearance, which helps designing compact panels; thereby reduces the material costs by. saving in busbar lenghs, sheet metal components, etc.
It is also call as busbar connection shroud / busbar joint cover, protection shroud(boot) etc.
