Product Description:

The rubber insulating mattings are manufactured as per the ASTM D 178 standard set by the American Society for Testing and Materials and are highly electrical resistant. These non-conductive rubber mats insulate and protect from mortal shocks generated by high voltage equipment.

The ASTM D 178 standard recommends thickness from 3.2mm to 12.7mm for the electrical insulating rubber mats depending on use/working voltage resistance with anti-skid textured surface on top and smooth lower surface. These safety rubber mats (Type-I grade) are leakage, moisture and water proof that guarantee long functional life. Type-II grade insulating matting offers additional properties such as ozone, flame and oil resistance. Manufacturer’s Test Certificate is provided along with the supply.

Application Area:

  • Near HT/LT Control Panels
  • Electrical Substations
  • Transformers, Generator & Lift Rooms
  • In front of Switchboards
  • Around Buss Bars
  • Outdoor/Indoor On-site use on Live Equipment
