NXL Series strain clamp (wedge type) is suitable for distribution wire up to 10kV, fixing the aerial insulation aluminium conductor or naked aluminium conductor on the rotate angle or insulator of terminal strain pole, and then fixing and tighting the aerial conductor, insulation cover and strain clamp are used together. It’s action is insulation protection.
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.
