Introduction of the role and characteristics of the wedge type tension clamp

As a common type of tension clamp, wedge type tension clamps are also used frequently in power transmission and distribution lines. The wedge type tensile clamp mainly uses the wedge type principle to lock the steel strand in the wedge clamp. During the installation process, the steel strand is first bent so that the curved shape of the strand is like a wedge and then installed in the wedge clamp. After the strand is subjected to the tensile force, the wedge and the strand are slid together with the outlet of the guide wire. The friction between the wedge and the strand is more and more due to the pressure of the wedge and the strand being clamped by the wedge-shaped cap line. Large, to achieve the role of fixed anchor steel strands.

Scope of application

In addition to the use of wedge-type tension clamps, wedge-type tension clamps are also used to fasten lightning conductors, and even wedge-type tension clamps can be seen in the cable pull of the cable tower. application.

Features

The characteristics of the wedge type tension clamp are very obvious. First, the convenience of installation and disassembly is the main feature of the wedge type tension clamp. Unlike other tensile clamps that use conductive conductors as electrical conductors, the wedge-type tensile clamps can be removed after installation and the process is simple to install or remove the wedge-type tensile barrier.

Not only to withstand the tensile force of the strand, the wedge-type tension clamp is also applied to the end of the overhead insulated conductor and the insulator string at both ends of the tensile end, the role of which is to make the overhead conductor tightened. Another advantage of using a wedge-type tension clamp is that it does not require the removal of the insulation of the wire when it is fixed to Xi'an, which is evident in the ease of installation.

Unlike other types of tension clamps, wedge-type tension clamps are not commonly used as electrical conductors, so in terms of electrical performance, wedge-type tensile clamps have very stringent requirements.
