E/INSULATION ™ is a minimum 20kV phase-to-ground flame
and arc resistant coverup. Electrically insulating and made from
High Temperature Vulcanized Silicone, it is split for ease of
application. The silicone of E/INSULATION™ is the same type
commonly used for polymer or non-ceramic insulators being sold
today.
The cross section of E/INSULATION™allows the substation
electrician or the distribution lineman ease of application.
The hose is simply pulled and split apart allowing it to be quickly slipped onto round or angle
substation cable or bus.
Because E/INSULATION™ is formed from High Temperature Vulcanized Silicone, it is very pliable
at all temperatures, yet it is tough and robust to allow extremely rough handling, the abuse of line
trucks and hundreds of on and off applications.

E/INSULATION™ Covers:
  • Round Bus
  • Angle Bus
  • Flat Bus
  • I-Beam

E/INSULATION™ is used for the purpose of:

• Preventing tree and animal contact outages on uninsulated cable
• Covering and insulating substation aluminum and copper bus and cable, as well as distribution lines..
• Residential weather head cable covering, replacing expensive line hose.

E/INSULATION™...

• CAN BE LEFT IN PLACE
• WILL NOT CHANGE COLOR OVER TIME
• WILL NOT CHALK
• PREVENTS VOLTAGE PUNCTURE FROM PHASE-TO-GROUND
OR PHASE-TO-PHASE CONTACT
