wedge type and insulation cover（ NXL ）
wedge type and insulation cover（ NXL ）
Application
NXL series wedge type tensioning wire clamp is suitable for 20kV and below distribution lines, the overhead insulated aluminum conductor or bare conductor is fixed on the insulation of the corner or terminal tensioning rod, so as to fix or tighten the overhead conductor, insulation cover and tensioning wire clamp matching use, play the role of insulation protection.
Structure feature
1. Choose the unmagnetic character high-intersityoxidation resistance aluminum alloy ,no waste electric energy
2. Wedge-locked structure,easy-insulation
3. An arc embraces the most part,conductor cannot change .large grip strength
Insulation cover performance feature
1.1-10KV withstand voltage：≥18kv keep voltage one minute not breakdown
2.20kv withstand voltage ：≥30kv keep voltage one minute not breakdown
3.insulation resistance：＞1.0×1014Ω
4.Environments temperature：－30℃~90℃
