Products Information

We supply both high voltage and low voltage power line insulators for power transmission lines. Our power line insulators, made of composite polymer, are much more durable and eco-friendly in performance than those made of glass or ceramic. Information below is about Low Voltage 220kV Polymer Composite Power Line Insulator.

Features:
1) Manufactured by means of injection whole-molding technology;
2) The juncture between end fitting and core is totally embedded in HTV silicone; rubber, eliminating conventional and traditional seal defects.

Materials:
1) Silicon Rubber for sheds/ housing;
2) Glass-fiber reinforced epoxy resin rod (ECR type) for core;
3) Hop dip galvanized cast steel for metal fittings.

Electromechanical specifications:
1) Rated voltage: 220kV
2) Specified mechanical load (tensile): 100kN
3) Arcing distance: 2000mm
4) Creepage distance: 6400mm
5) Section length: 2240mm
6) Lightning full-wave impulse withstand voltage (peak value): 1000kV
7) 7.1 min wet power-frequency withstand voltage(effective value): 395kV
8) Routine test load: 50kN
9) Approximate net weight (grading rings included): 14.1kg
