The difference between overhanging wire clips and tensioning clips

1. Definition of overhang clamp and tensioning clamp

Overhanging clamp and tensioning clamp are common insulation clamp in power transmission and distribution. Their main function is to connect various electrical equipment, bear a certain tension and protect conductive lines. The difference between the two is their application and installation location.

Overhanging wire clamp, mainly used for wire suspension occasions. During the suspension of the wire, the suspension clamp ensures that the wire remains suspended under normal working conditions and distributes tension evenly. The overhang line clamp is generally divided into single hanging point and double hanging point. The single hanging point is mainly used for fixing the anchor section, while the double hanging point is suitable for the tension adjustment of the middle file.

Tension clamp is widely used in overhead transmission lines. The tensioning clamp can fix the wire through insulators, hanging plates, etc., and bear additional loads to eliminate the stress caused by wind loads, temperature changes, etc., and ensure the normal operation of the line. The tension clamp can not only protect the wire, but also distribute the voltage to the support, reduce the load pressure on the support, and improve the service life of the line.

2. The similarities and differences between the overhanging wire clip and the tension wire clip

Although overhanging wire clips and tensioned wire clips differ in application, they also have a lot in common. Both have insulation properties to protect lines and equipment from damage, and both have good corrosion resistance and can adapt to complex environmental conditions.

The difference is that the overhang clamp is mainly used for shorter spans, while the tensioning clamp is suitable for longer spans, so there are differences in manufacturing processes and materials. In addition, the overhang clamp is mainly used to adjust the tension of the wire, and the tension clamp is mainly for the problem of wire tension in the case of large span.

3. Application and precautions of overhanging wire clip and tensioning wire clip in power transmission and distribution

Both overhang clamp and tension clamp have important application value in power transmission and distribution. Overhanging clamp is mainly used in urban power supply, communication and railway infrastructure construction; The tension clamp is widely used in high voltage transmission lines, large substations and overhead cables.

When using overhang clamp and tensioning clamp, the following points need to be noted:

a. Install in strict accordance with the product operating procedures to avoid improper assembly.

b. Accurately estimate the weight and length of cables, lines, etc., and ensure that the appropriate size of the overhang clip and tensioning clip is selected.

c. Regularly check the overhang clamp and tension clamp, and timely replace the aging, damaged or hidden safety problems of the clamp.

d. Take appropriate anti-corrosion measures to ensure the long-term safe and stable operation of the overhang clamp and the tensioning clamp.

In short, the overhanging clamp and the tensioning clamp are indispensable insulation clamps in power transmission and distribution. Although their application scenarios and installation positions are different, they all play an important role in protecting the safe operation of electrical equipment.
