Insulators
used in power transmission network are classified into 3 main
categories based on their dielectric material : Porcelain,
Glass and Composite insulators. Porcelain insulators are in
use for 100 years. Adoption of Glass insulators was low.
Development of silicone material suitable for injection moulding
was the turning point. Introduced more than 2 decades back
in global market, composite insulators were considered niche
products for applications in severe weather condition have
now become threat to Porcelain insulators in most HT installations.
This
technology was mastered by Goldstone Teleservices with extensive
research. Goldstone, at present manufactures 15 kV, 25 kV
and 35 kV Insulators for the power sector and 25 kV for the
railway traction and for 66 kV, 132 kV, and 400 kV power transmission
lines.
