35kv composite post type insulator

1.35kv composite post insulator 2.confirm to GB/T19519-2004,JB/T8460-1996 3.certification:ISO9001

APPLICATION:

Polymer (Silicone) insulators are intended for use in highly contaminated areas, and are frequently located less than 50m from the coastline, sometimes directly exposed to salt spray for the ocean.

CONSTRUCTION:

Core: The axially aligned glass fiber reinforced resin rod that forms the mechanical load-bearing component of the insulator.End fittings: The insulator attachment hardware that is connect to the core.Weathershed: The external part of the insulator that protects the core and provides the wet electrical strength and leakage distance.

Suspension Insulator: The term used in this specification means any insulator intended to carry primarily tension loads and includes tangent and dead-end installations.

Pin/Post insulators: The term used in this specification means any insulator intended to carry tension, torsion, bending or compression loads. It includes horizontal and vertical installation.

Pin insulators shall be of the one-piece type. Weathershed material for polymer insulators shall be one piece mould silicone construction, rigidly attached to the fiberglass core. Independent movement and the penetration of moisture between the core and the weathershed material is unacceptable. End fittings for polymer insulators shall be attached such that no moisture can penetrate to the core layer at attachment point.

35kv Composite post insulator is suitable for various area, especially filthy areas. This kind product’s anti-bending intensity is high and its performance in anti-pollution, anti-quake, anti-impulse, anti-rupture is excellent. Besides, its volume is small, weight is light, and convenient to install. Maintenance and manual cleaning is not needed. It is an alternative to porcelain post insulator.

 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
