Insulating Boots/Shrouds

Busbar Shrouds/Boots are protective flexible PVC covers that will aid in insulating switchgear connections, busbars, and all types of electrical terminations up to 36 kv. The shrouds are made from polyvinyl chloride/plastisol material and we have customized proprietary formulations to suit both low & high voltage applications. These shrouds are inter- nationally acclaimed and are being made mandatory across the switchgear industry.

Salient Features of shrouds

  • * Flame retardant UL94/VO.
  • * Easily mountable & Re-usable.
  • * Wide working temperature range.
  • * Standard models and customized designs.
  • * Provides significant reduction in air clearances.
  • * High dielectric strength and good ageing properties.
  • * Cost effective solution to time consuming insulation tape.
  • * Reduces maintenance cost with less distribution interruption.
  • * Available in popular colors like red ,black , yellow, blue and transparent.
  • * Ensures electrical safety and helps prevent voltage related injuries during maintenance.

These Boots/shrouds are manufactured through dip moulding process under stringent ISO quality standards. The raw materials used in the process are in compliance to RoHS standards. We're a trusted supplier of these boots to both domestic and global OEM switchgear manufacturers We have a wide variety of boots to choose from or we can also provide tailor made solutions as per the customer requirement.
