NLLSelection Table for Series Bolt Type Tension Clamp
☆ Product Usage
The NXL series wedge type tension clamp is suitable for 10kV and below distribution lines. It fixes overhead insulated aluminum wires or bare aluminum wires on insulators at corners or terminal poles, thereby fixing or tightening the overhead wires. The insulation cover is used in conjunction with the tension clamp to provide insulation protection.
☆ Structural features
◆ Choose non-magnetic high-strength anti alumina alloy material
◆ No energy loss, it is an energy-saving certified product
Wedge block locking structure, easy and reliable installation
◆ The arc is tightly held over a large area, making the wire less prone to creep and providing a strong grip
☆ Performance characteristics of insulation cover
◆ 1-10kV power frequency withstand voltage: ≥ 18kV withstand voltage for 1 minute without breakdown
◆ Insulation resistance: ＞ 1.0 × 1014Ω
◆ Environmental temperature: -30 ℃ -90 ℃
◆ Climate resistance: Good performance after 1008 hours of artificial climate aging test
