Product Description

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
 

What is the function of a Tension Clamp?

1,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.
 

2,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.
 

3,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.

 

What are the types of tension clamps for overhead lines?
According to the design, tension clamps are divided into the following categories:
1,Wedge type tension clamp
2,Cone tension clamp
3,Compression dead end clamp
4,Bolted type tension clamp
