Products Description
NLL Type Galvanized Cable Suspension Clamp tension clamps Dead End Clamp
NLL series bolt type tension clamp is mainly used in standing electric power line or substation, stationary conduction line and lightning conductor and also be used in jointing the strain insulators by joining hardware or jointing the lightning conductor with the perch.
It is designed for aerial lines up to 30kV.
1) Be suitable for fixing insulated aluminum conductor or naked aluminum conductor on the rotate angle or insulator of terminal strain pole, to fix and tighten the aerial conductor.
2) Material: body, keeper - aluminum alloy, split pin - stainless steel, others - hot-dip galvanized steel.
3) Grip strength of the clamp is more than 95% break strength of the conductor.
4) Insulation cover and strain clamp used together for insulation protection

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.

Product Design Feature
The design, shape and dimension of the tension clamps for the overhead line will determine its usability and how it will be connected to other components on the pole line.
The tension fitting design should be in such a way that it allows the fitting to move freely along the conductor.
The design of the tension clamp fastening should also minimize the load and fatigue on the cable.
The dimension of the tension clamp fastening entail parameters such as length, width and thickness. It should be accurate and match the pole requirement.
Connecting the tension clamp to the pole line should be an easy task thanks to the excellent design and dimension.

What is a Tension Clamp?
A tension clamp is a sturdy fitting that is used for completing the tensional connection on a conductor or cable. The fitting has different components that are connected to the cable a specific points.As it completes the connection, tension clamp helps to provide mechanical support to the insulator and also around the conductor.The design of a tension clamp ensures that it can easily fit at any point of the cable or conductor.
What is the function of a Tension Clamp?
* Providing mechanical connection
* Protect the cable/conductor
* Restrict the movement of the conductor
* Protect the cable/conductor
* Restrict the movement of the conductor
What should I look into when choosing tension clamps?
* Designs * Materials * Dimensions * Quality Compliance and standards
