Insulated tension clamp
Keyword:
Details
Use
NLL series bolt type aluminum alloy strain clamp is suitable for overhead lines with rated voltage of 10KV and below, power plants and substations. Overhead insulated aluminum wires or bare aluminum wires are fixed on the insulator of corner or terminal tension rod, so as to fix or tighten overhead wires. Insulating cover is added when insulated wires are used for insulation protection.
Due to the use of non-hysteresis high-strength aluminum alloy materials and heat treatment process, so the product has the advantages of high strength, less line loss, is worth promoting the energy-saving hardware.
Product Features
◆ The product adopts bolt to install the fastening wire, which is easy to install and has good grip strength, and the product can be reused.
The shell is made of high-strength, anti-oxidation aluminum alloy die-casting molding, with high strength, less line loss, no hysteresis, eddy current, energy saving and other advantages.
◆ The product can be equipped with an insulation shield with good insulation performance. The insulation cover of the product is made of weather-resistant insulation reinforced engineering plastics, and the AC withstand voltage of 45kV is applied for 1 minute without breakdown and flashover. Easy to install.
Performance characteristics of insulating cover
Power frequency withstand voltage: ≥ 45kV, no breakdown or flashover for 1 minute; Insulation resistance:>1.0 × 1014; Ambient temperature: -30 ℃, 90 ℃, weather resistance: good performance after 1008 hours of artificial weather aging test.
