Post Insulators

Porcelain Post cylindrical Insulators, operating at 30/36 kV Voltage. Capable for outdoor installation.

The Insulators are manufactured according to the Technical Description TD – 82 and IEC – 60273, IEC – 60168.

Description

The Insulators are used for bus support at the 30kV voltage level at the 400/150/30 kV air insulated ehv substations. They are manufactured by high quality porcelain and are brown colored.

All the metal components (bolts, nuts, and washers) are made of hot dip galvanized steel. The Insulators consist of 8 MI6 bolts that are used on the top and bottom fitting.

All the necessary metal components are included in the supply of the Insulators.
