CE / SGS Approved Polymer Suspension Insulators With Tongue / Clevis Metal Fittings

CE / SGS Approved Polymer Suspension Insulators With Tongue / Clevis Metal Fittings

46kV ANSI silicone rubber deadend insulator grey with tongue & clevis metal fittings

Description:

​46KV suspensin silicone rubber insulator must pass material design tests , then can come into mass production.  the following must be performed to cerfity a material for use in production.

​1 Tracking test :  a sample of material inclined at 30° and eletrodes positioned 35mm apart . samples are sprayed with a conductive solution and energized at 10kV . the cycle is repeated every 90 seconds. ​

​The sample must withstand 20000 test cycles.

2 Ultraviolet test : samples of rubber must be tested in a QUV tester.  it is exposed to high ultraviolet radiation and high humidity without cracking.

3 Corona Cutting

4 Oxidative Stability

5 Tear Strength.

only the material passed upper test items , we can say it is qualified .

Applications:

Suitable for tension string or suspension string in transmission lines 15kV ,25 kV,35Kv,46kV etc.
