Transmission lines are required to be more aesthetically pleasing and are routed through narrow right-of ways or along roadways. Also, at the lower transmission voltages (e.g., 115 kV and 69 kV) these lines are routed through urban areas and along roadways similar to distribution circuits to supply substations and larger customers.

HIVOLT silicone rubber line post insulators are manufactured and tested to IEC , ANSI etc. international standards,Quality System is registered to ISO 9001 Quality Systems.

The core rod of the line post insulator is made of a high quality fiberglass that has been specially
formulated for electrical and mechanical applications.
The housing and sheds of the insulator are one piece, injected molded silicone rubber that is chemically bonded to the core rod. This ensues that the interface between the rubber and rod is impenetrable against moisture ingress.


Transmission line post insulators are used on overhead transmission lines operating at and above 66 kV. These insulators are commonly installed horizontally on metal or wooden structures to support the
conductor. Also, these insulators are used to support high voltage conductor jumpers .

Competitive Advantage:

Improved Reliability (interruptions and outages due to vandalism, pole fires, and flashovers in all types of
environments are a thing of the past)
• Eliminate or Reduce Maintenance and is compatible with existing plant
• Improves Power Quality (lower RI and TVI)
• Energy Efficiency (reduced losses due to lower leakage currents)
• Safety (light weight for handling and installation)
• Service Life (consistent performance over its service life)
• Life Cycle Cost (savings over porcelain insulators)
