As one of 33KV line post insulator, 33kV 4kN porcelain line post insulator for installation on wood poles to support, fixing wire and insulation with creepage distance 786mm.
33KV line post insulator/33kV 4kN porcelain line post insulator design:
The economical design for our porcelain line post insulators lasts far longer in the field. With many in operation for the last 20 years, these line post insulators exhibit no change in their mechanical/electrical characteristics, proving to be highly reliable in the field.
33KV line post insulator/33kV 4kN porcelain line post insulator application:
33KV line post insulator/33kV 4kN porcelain line post insulator consists of porcelain and metal accessories with cement gel pack for insulation and support in the overhead power line wires. And ceramic line post insulators are normally used for under 132 kV power line. As a line support wires as like porcelain pin insulator, one end of the line post insulators connection wire, one end is installed on the cross arm, unlike pin insulator, line post insulator is the breakdown type.
