2 Product classification
Tension clamps can be roughly divided into two categories according to their structure and installation conditions:
Category 1: Tension-resistant wire clamps must withstand all the tensile force of the conductor or lightning protection wire. The clamp's holding force is not less than 90% of the rated tensile strength of the installed wire or lightning protection wire, but it does not serve as a conductor. This type of wire clip can be removed after the wire is installed and used separately. This type of cable clamps include bolt-type tension cable clamps and wedge-type tension cable clamps.
Category 2: In addition to bearing all the tensile force of the wire or lightning protection wire, the tension clamp also serves as a conductor. Therefore, once this type of cable clamp is installed, it cannot be disassembled and is also called a dead cable clamp. Since it is a conductor, the installation of the cable clamp must be carried out carefully in compliance with the relevant installation operating procedures.
3 Features
1) The wire clip has high strength and reliable grip. The gripping strength of the wire clip should not be less than 95% CUTS (calculated breaking force of stranded wire).
2) The clamp distributes the stress on the twisted wire evenly without damaging the twisted wire, improves the vibration resistance of the twisted wire, and greatly extends the service life of the conductor.
3) Simple installation and convenient construction. The construction time can be greatly shortened, and no special tools are required, and the operation can be completed by one person.
4) The installation quality of the cable clamps is easy to ensure and can be inspected with the naked eye without special training.
5) Good corrosion resistance and high-quality materials. The material is exactly the same as the wire, ensuring that the clamp has strong resistance to electrochemical corrosion.
6) An anti-theft ring is optional to effectively solve the anti-theft problem.

Advantages:
1.Convenient installation: No need of special tools and cutting the wire
2.Grip and Failure load: Increased as the body and the wedge core of Bolt Type Strain Clamp is made of high strength aluminum alloy materials
3.Features:With Self-locking function to pull the wire tight ,which increasing the safety and reliability of the line and reusable advantage after removing
4.Significant effect:No cutting of the wire brings electrical contact point reduce, low loss, energy-saving of transmission line.

Quality Control
The function of tension clamp:
1. Connection function, used for line corners, connections, and terminal connections.
2. Protection function, its performance and efficacy can protect and assist vibration reduction of optical cables.
3. Fixing function: the tension clamp can withstand the tension of the wire and is used to fix the wire or the cable of the tower.
Bolt type aluminum alloy tension clamps are suitable for fastening various overhead conductors at corners and terminal poles in power plants, substations and distribution lines.
NLL series strain clamps are suitable for aerial line up to 10kv, fixing aluminium wire or steel core aluminium wire
on the strain pole.
