Lightning-Proof Pin Insulators with inner gap

1. Patent Product 2. lighter than porcelain insulator 3. replace porcelain insulator 4. unique sealing with three layers

  Patent Number: 200420012166.78

All rights reserved.

 

1. both functions of metal oxide arresters and polymeric insulators with inner-set air gap

2. to prevent actuating-tripping of distribution line outlet protection

3. to prevent  the lightning-caused breaking failures of insulated overhead lines

4. Acupuncture mechanism of white steel does not damage insulated line and does not affect original function of wire.

5. used in environment of marsh and high mountain

6. Lightning strike out rate and insulation breakdown accident rate as well as line trip out rate have been reduced.

7. good hydrophobicity, anti-aging properties, and tracking and erosion resisting capabilit, ultimate tensile strength and bend     strength

8. unique sealing technology with three deep water proof layers

9. half weight of porcelain

10. special down lead and grounding grid are not necessary

11.  In operational distribution line, the lightning-proof pin insulators are installed per 200m, and lightning protection effect 94% can be reached .
