Electric network in India operates under
very harsh environments. Industrial pollution, marshy land, hilly and
unfriendly terrain, extreme weather, coastal region etc. make insulator
contamination flashovers the main concern to the electric utility. Variety
of solutions were tried to combat the insulator pollution flashover.
Initially ceramic insulators were in use and then the glass insulators were
put to use, but these did not serve the flashover issue. The introduction of
Composite Insulators(Polymer Insulators) OR Silicone Insulators was a turning point in
the 1970s.
These silicone rubber insulators / composite insulators were popular for
their pollution resistance and were useful ever in sever / harsh weather
conditions. The composite insulators have distinctively hydrophobic surface
and are resistant to chemical influence, weathering, UV radiation. The
physiochemical and mechanical properties of these rubber composite insulators remain constant
over wide temperature range. Hence there are negligible changes in the
properties of polymer insulation and no electrical or mechanical failures
are experienced.
Composite insulators we offer can be custom specified, manufactured, tested
and are reliable for their service life. They are ideal for use in HVAC,
HVDC and in most HV application.
