Aluminum alloy tension clamp for transmission lines type NLL-3 with
This is a simple device that comprises of several parts which are
used for terminating conductors at different points. The device is
also used to provide adequate mechanical and electrical connection
to the insulator strings which is around the conductor.
The clamps can support conductors on the straight sections and as
well as those on the twisted sections.
When in the twisted sections, tension clamps up to an angle of 90
Materials used on Tension Clamps:
1) The main materials used are aluminum and cast iron.
2) These two materials are preferred because they are compatible
3) they can survive well under different conditions without
corroding or rusting.
4) The selection of these two materials is also based on their
5) They are extremely hard and can’t be easily affected by
Here are some of the uses of tension clamps:
1) Tension clamps are designed to provide strong and safe
mechanical and electrical connections regardless of the conditions.
Whether the cables are having longitudinal tension or even maximum
working loads, tension clamps are still able to provide an adequate
connection that is coupled up with the longitudinal grip.
2) The design of the tension clamps enables them to protect the
3) Usually, conductors and transmission lines are exposed to the
vagaries of nature such as wind and storm.
Sometimes, the wind can be too strong such that it can cause
movements and vibrations of the conductors.
In doing so, the vibrations can emanate from the conductor and data
By controlling random movements, tension clamps help to limit the
vibrations that emanate from the conductor.
Although there could be other functions of the tension clamps, the
three that we have mentioned are vital for any overhead lines.
