    Wedge Type Tension Clamp
    2022-01-04

    Tension clamp is one type of single tension hardware that used for completing the tensional connection on a conductor

    or cable, and it provides mechanical support to the insulator and conductor. It is usually used with fitting like clevis and

    socket eye on the overhead transmission lines or distribution lines.

    Bolted type tension clamp is also called dead end strain clamp or quadrant strain clamp.

    What are the different types of tension clamps?


    In principle, two types are available: Wedge tension clamps, are made of two forged bodies connected by a hinge with

    coresponding r wedges. These can be with or without jumper connection.

    You can connect it at the straight point and even on the twisted sections of the conductor cable.

    Apart from being physically strong, tension clamp is highly flexible. This is why it can support the twisted section up to 90 degrees.


    Materials for Tension Clamps

    Before you buy and use tension clamp, you should confirm what it is made of.  The material must be compatible with the

     conductor application. This property is vital as it will determine how strong the tension clamp fastening fitting is.

    Our tension clamps are made of high-grade aluminum and cast iron materials.

    The most attractive feature of these materials is their strength and electrical conductivity.

    They are physically strong while at the same time compatible with different conductors.

    Aluminum is also capable of functioning well under different conditions without degrading or getting damaged. It can

     withstand extreme temperature ranges.

    Alloys of aluminum can also be used as long as they meet the technical requirements of the tension clamp.

    The surface treatment of this fitting is hot-dip galvanizing. According to the corrosive environment, the zinc layer thickness 

    should be adjusted within a certain range.



    What is the function of a Tension Clamp?

    • Providing mechanical 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.Tension clamp is designed to give the cables or conductors a strong

    mechanical and electrical connection.

    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.The longitudinal grip of the tension cable is also attributed to mechanical support.

    • Protect the cable/conductor 

    Tension cable is also good at playing a protective role.

    The ergonomic design of this power line fitting ensures that the cable remains at the desired position at any given time.

    This protection is usually important especially against the installation loads.

    • Restrict the movement of the conductor

    Elements of weather such as wind and storm tend to cause unwarranted movements on the conductor. This is an addition to

    natural calamities such as tremors and turbulence among others.

    Constant movements and vibrations of the conductors can disrupt the normal transmission of data and electric current.

    Quality tension clamps are capable of limiting such movements by ensuring that the cable remains sturdy regardless

    of the external factors.
