69KV porcelain line post insulators

69KV porcelain line post insulators have better performance for its salient features in distinctive geometrical configuration, smooth surface, good quality glaze applied and metal used for end fittings.

Our porcelain line post insulators ensure maximum creepage path due to their distinctive geometrical configuration. Smooth rounded contours of shell provide protection against chipping. The glaze applied is compressive in nature, adds to mechanical strength and provides smooth surface for self cleaning under contamination. Caps are made of malleable cast iron and spindles of forged steel. These end fittings are galvanized to provide better protection against corrosion.

69KV porcelain line post insulators thermal shock test:
Three 69KV porcelain line post insulator products shall be selected at random and tested for ten complete cycles in accordance with 5.5 of ANSI C29.1. The temperature of the hot water bath shall be approximately 66℃, and the temperature of the cold water bath shall be approximately 4℃. If one or more line post type insulators fail, three additional insulators shall be selected at random and tested. Failure of one or more of these additional insulators shall constitute failure to meet the requirements of this standard.

We are exporting 100% of all our 69KV porcelain line post insulators for past 20 years to Malaysia, Singapore, Thailand, Indonesia, Brunei, Myanmar, Sri Lanka, Middle East, Africa, U.K. and Europe.
