NLL Series Strain Clamps
The strain clamp is mainly used to fix the wire to withstand the tension of the wire and hang the wire to the tension string or the metal fitting of the tower. Strain clamps are used for corners, splices, and terminal connections. Spiral aluminum-clad steel wire has extremely strong tensile strength, no concentrated stress, and plays a role in protection and auxiliary vibration reduction for overhead lines.
- The clamp has high strength and reliable grip. The grip strength of the clamp is not less than 95% CUTS.
- The stress distribution of the wire clamp to the stranded wire is even, and the stranded wire is not damaged, which improves the seismic resistance of the stranded wire. Effectively extend the service life of the conductor wire.
- Simple installation and easy to use. It can greatly shorten the construction time, without any special tools, one person can complete the operation.
- Our wire clamps are made of high-quality materials with strong corrosion resistance.
- The buckle structure is simple to install and can be reused.
Tension Resistance of Strain Clamps
NLL Aluminum Alloy Strain Clamp
Strain clamps can be roughly divided into two categories according to different structures and installation conditions.
- The first category: The strain clamp must withstand the full tension of the wire or lightning conductor, and the grip strength of the clamp is not less than 90 of the rated tensile strength of the installed wire or lightning conductor, but it is not used as a conductor. This type of clamp can be removed after the wire is installed and used separately.
- The second category: In addition to bearing the full tension of the wire or lightning conductor, the strain clamp also serves as a conductor. Therefore, once this type of clamp is installed, it cannot be disassembled, which is also called dead clamp. Because it is a conductive body, the installation of the wire clamp must be carried out carefully in accordance with the relevant installation rules.
*NLL series is suitable for aerial line up to 10KV, fixing aluminum wire orsteel core aluminum wire on the strain pole.
Advantages of Environmental Use
- Effectively prevent short-circuit accidents caused by overlapping small animals such as birds and beasts or foreign objects.
- Prevent electrical accidents caused by condensation flashes, dirty flashes and icicles sticking to the snow.
- Prevent acid rain, salt fog and harmful chemical gases from corroding the incoming and outgoing wires of the transformer.
- Avoid personal injury or death accidents caused by pedestrians accidentally touching exposed electrical contacts.
- The fully enclosed operation of the protective cover and metering device can prevent criminals from stealing electricity.
The outer diameter of the wire includes the wrapping. Note: The above parameters are for reference only. The specific size depends on the cable or project requirements for selection. Enquire Us Now.
