Description:

NLL 35KV bolt aluminum alloy strain clamp is suitable for distribution wire up to or over 35KV, fixing the aerial insulation aluminium conductor or the naked aluminium conductor on the rotate angle or insulator of terminal strain pole, and then fixing and tightening the aerial conductor; the insulation cover and the strain clamp are used together for insulation protection.

Features:

1. Non-magnetic special aluminum alloy body, after heat treatment, has the advantages of high strength and low line loss

2. Each U-bolt is fastened to a separate pressure block to ensure uniform contact pressure.

3. The pressure block is fixed on the U-shaped bolt by doing things, avoiding falling off during installation and more convenient construction.

4. Good stress control: Clamp curvature R≥8 times wire diameter D

Notes:

1.N – Strain Clamp, L -Bolt Type, L – Aluminum Alloy, Number – The Product Serial Number

2. The body and briquetting are made of aluminum alloy with energy saving effect. The closed pin is made of stainless steel and the rest are hot-dip galvanized steel

3. The grip strength of the wire clamp is not less than 95% of the calculated breaking force of the wire

4. The wear-resistant bushing is added into the iron pin hole to become a wear-resistant tension clamp
