Pretwisted tensioning clamp is a kind of golden tool used in line erection, mainly used to connect optical cable or wire and tower, with the function of protecting optical cable, improving seismic performance and withstand tension. ‌ The prestranded tensioned wire clip is composed of inner stranded wire, outer stranded wire, insert ring, U-ring, extension ring, bolt, nut, closing pin and other parts ‌1.

Its functions are mainly reflected in the following aspects

Protection optical cable: The special design of the pre-stranded tension clamp can evenly distribute the stress and avoid the stress concentration point, so as to play a good role in protecting the optical cable.

Improve seismic performance: aluminum-clad steel prestranded has seismic effect on optical cable and can enhance the stability of optical cable lines in natural disasters such as earthquake.

Bearing tension: the pre-stranded tensioning clip can withstand greater tension, and its holding force is not less than 95% of the ultimate tensile strength of the cable, which is completely suitable for the needs of the cable erection. In addition, the pre-twisted tensioning clip also has the characteristics of easy installation, one person does not need any special tools to quickly complete the installation ‌. At the same time, because it is made of hot dip galvanized steel wire or aluminum clad steel material, it has strong corrosion resistance.

In the power system, the prestranded tensioning clamp is widely used in the tightening and tensioning of overhead lines and the connection between optical cable lines and towers. Its superior performance and convenient installation make it an important part of the power system.

Function

This product is used for the link between opgw cable and tower in the erection of opgw cable. The aluminum-clad steel prestranded wire can protect and improve the anti-seismic function of OPGW cable.

Composition

Inner twisted wire, outer twisted wire, insert ring, U ring, extension ring, bolt, nut, closed pin, etc.

Features

1, The application force has no concentration point, uniform stress, and has a good protection effect on the optical cable.

2, In the case of not exceeding the side pressure strength of the cable, the cable has a larger grip and can withstand greater tension.

3, The grip of the cable is not less than 95% of the cable limit resistance such as tensile strength (uts), completely suitable for the needs of cable erection.
