Composite post insulators

Composite post insulators consist of the upper and bottom metal accessories and insulation (silicone rubber) glued together by glue. Metal accessories generally made of cast iron, brush on the surface rust or galvanized.

The Composite post insulators can be designed into
◆ Rated voltage: 7.2kv, 12kv, 24kv, 40.5kv, 72.5kv, 126kv, 252kv, 362kv and 550kv
◆ The mechanical strength: outdoor insulator – 2kn, 4kn, 6kn, 8kn, 10kn, 12.5kn, 16kn, 20kn
Indoor insulator - 2kn, 4kn, 6kn, 8kn, 25kn
◆ The indoor post insulators used for 7.2 to 40.5kv

According to insulator usage, Composite post insulators can be divided into
◆ Capped post insulator
◆ Capless post insulator

The features of Composite post insulators
◆ Good bending strength
◆ Good pollution performance
◆ Earthquake resistance
◆ Light weight, easy to install

Composite post insulators are also called polymer post insulators and designed in accordance with ANSI C29.9 and other insulator specifications.
