Tension-tolerant wire clamp is a device that fixes the transmission line conductor on the tower. It is mainly used in high-voltage power lines, through the conductor of the firm clamping, to ensure that the conductor in the wind load and other external forces do not come loose, so as to maintain the safety of the power system and stable operation.

Such as the red part of the above picture is the tensioning wire clamp, it will be clamped at one end of the wire, the other end of the bolt fixed in the tower, and then connected with the blue line on the diversion line figure, thus playing a role in reducing the tension of the wire. If the conductor is released too long and not set up the tension-resistant tower, the conductor will receive too much tension, thus causing the breakage of the accident. Therefore, the tension-resistant wire clamp in the high-voltage lines is particularly important, is a high-voltage line can be the fundamental guarantee of long-distance transmission!

The following is about the high-voltage power lines in the tensioning clamps of some small knowledge:

Structure and principle: tensioning wire clamps are usually composed of clamp body, sleeve, nut, washer and other parts. Clamp body through the clamping effect, to ensure that the wire can be subjected to sufficient tension and not be slipped. The nut is adjusted so that the clamping force can be adapted to the different diameters of the wire.

Material: Tension Resistant Clamps are usually made of high strength, corrosion resistant materials such as galvanized steel, stainless steel, etc. This helps to ensure that the clamps can be used in a variety of environments. This helps to ensure that the clamps maintain stable performance in a variety of environmental conditions.

Uses: Tension Resistant Clamps are widely used in transmission lines, substations and other power systems for connecting wires, grounding wires and so on. They can not only withstand the weight of the wire itself, but also maintain the stability of the wire under external wind loads, ice loads, etc.

ADJUSTMENT: When installing the tensioning wire clamps, they need to be properly adjusted according to the diameter of the conductor and the type of the clamp. This will ensure that the line clamping force is moderate, not too tight to lead to excessive force on the wire, not too loose to lead to loose wire.

Anti-corrosion measures: As the power system is usually in the outdoor environment, the corrosion resistance of the clamp is critical. For this reason, some tensioning clamps are galvanized or stainless steel to increase their service life.

Regular Inspection and Maintenance: Regular inspection and maintenance is necessary to ensure the proper functioning of tensioning clamps. This includes checking the clamp body, nuts and other components for corrosion, loosening and other conditions to ensure its normal working condition.

These are some basic knowledge about tensioning clips in high voltage power lines, these tips help to understand the important role of tensioning clips in the power system and the precautions for use and maintenance.
