high-strength aluminum alloy strain clamp

The body of NLL series aluminum alloy strain clamp is made of high-strength aluminum alloy ,it is suitable for aerial line up to 20kV, fixing aluminum wire or steel core minium wire on the strain pole, aerial insulation aluminum conductor and insulation aluminum cover are being used together, and the action is insulation protection.

Strain clamp

Insulation cover performance feature  
1.Withstand voltage: ≥18kV keep voltage one minute not break down
2.Insulation resistance: >1.0×1014Ω
3.Environments temperature: -30℃~90℃
4.Weather proof performance: have good performanced after 1008 hours artifical climate aging test.
