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
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 .
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
• 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)
