Bushing Boot
 
 
Bushing Boots are non-tracking elastomeric insulating boots which are used in conjunction with terminations. They fit over the bushing of switchgear, insulating the area between the cable connector in either right angled or straight bushing connections. They are designed to enhance the phase-to-phase and phase-to-earth insulation. The boots can be used up to 25KV application & protect against flashover or surges induced in swichgear & transformer boxes.
