Utility pole guy wire8/29/2023 This ends up forming a wedge-like structure. The design of this tension clamp comprises two forged bodies that are connected to each other by a hinge. Wedge tension clamps are quite versatile as they are used in both overhead lines and as well as substations. In terms of the design, tension clamps are divided into the following categories: Wedge tension clamp When used as a conductor, you should follow safety procedures when installing it on the pole line. It takes the pulling force from the conductor while at the same time it acts as a conductor. This category of tension clamp plays two roles simultaneously. The bolted type and the wedge type fall under this category. It has a high grip strength which is not less than 90% of the rated resistance of the conductor. This type of tension clamp is designed to bear all the weight and tension that is on the conductor. Since there are different kinds of transmission lines, it is only necessary that the tension clamps are not all the same.Īccording to functionalities, there are two broad categories of tension clamps. Types of Tension Clamps for Overhead Lines Quality tension clamps are capable of limiting such movements by ensuring that the cable remains sturdy regardless of the external factors. This is an addition to natural calamities such as tremors and turbulence among others.Ĭonstant movements and vibrations of the conductors can disrupt the normal transmission of data and electric current. Restrict the movement of the conductorĮlements of weather such as wind and storm tend to cause unwarranted movements on the conductor. This protection is usually important especially against the installation loads. The ergonomic design of this power line fitting ensures that the cable remains at the desired position at any given time. Tension cable is also good at playing a protective role. The longitudinal grip of the tension cable is also attributed to mechanical support. The support that is given by the tension clamp shields the cable in all the conditions, whether it is the working load or the longitudinal forces that are acting against the conductor. Tension clamp is designed to give the cables or conductors a strong mechanical and electrical connection. Under normal circumstances, cables for poles and telephone lines are subjected to different forms of mechanical forms They need to be adequately supported so that they can remain in their desired positions. To bring the matter into a clearer perspective, here are the key functions of tension clamp: Providing mechanical connection What is the function of a Tension Clamp?Īs we have just mentioned, a tension clamp is used for giving cables mechanical and electrical support. This is why it can support the twisted section up to 90 degrees. You can connect it at the straight point and even on the twisted sections of the conductor cable.Īpart from being physically strong, tension clamp is highly flexible. The design of a tension clamp ensures that it can easily fit at any point of the cable or conductor. The fitting has different components that are connected to the cable a specific points.Īs it completes the connection, tension clamp helps to provide mechanical support to the insulator and also around the conductor. Types of Tension Clamps for Overhead LinesĪ tension clamp is a sturdy fitting that is used for completing the tensional connection on a conductor or cable.
