Electric Insulator

Electric Insulator
Product Detailed
Insulator: 1) Silicon Rubber for sheds/ housing 2)Rated voltage:10KV~220KV 3)IEC Standard

Features of insulator:

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

4) Rated voltage:10KV~220KV

5) 5000hours aging test.

6) IEC Standard.

Insulator Installation:

1.Shed:the design of shed adopted unique aerodynamics principle.

2.Shed and Sheath:the shed and sheath adopted the whole moulding technique.

3.The end seal adopted the high temperature sulfuration high pressure seal technique to achieve to the aim of three-protection to ensure the end seal of metal fitting is reliable performance

4.Sheath thickness accord with the IEC international standard 

5.Core rod:Adopt ERC high-temperature fortified(acid-proof) model core rod

6.Connection:Adopt international advanced compaction joint technique for metal fitting connection

7.The galvanizing coat of metal fiting adopt the technique of rare earth aluminum hot galvanizing to avoid the zine continue drop out during compaction joint.


Small volume easy to maintain;light weight easy to install; high mechanical strenth no broken;excellent seismic performance;well pollution resistant short production cycle;high stable quality.
