Controlled Cable Tensioning

A tension test for measuring cable tension in overhead electricity and communication lines is very important because of environmental influences that often affect the cable length. Changes in cable length obviously alter cable tension and may eventually lead to cable failure. A cable pull test enables controlled cable tensioning that actually solves the problem. A wire pull test which enables the optimal cable tension to be reached is also very important in suspension bridges and other structures that are stabilized and supported by steel cables and guy wire ropes.

In these applications the wire tension test and optimal tensioning are important for stabilization of the structures. 

There are several important features that make the tension and pull scale especially suitable for cable or wire tension testing.The Ron dynamometer scale and load cell series are especially suitable for wire and cable pull test applications:  

>The Ron dynamometer scale, load cell, and overload detector series are very lightweight and therefore portable.
They are available in small carrying cases, have disposable batteries for 2000 hours use and are convenient for working on-site.

This special feature enables the Ron dynamometer scales and load cells to enjoy a significant advantage in the portable use market segment for all those applications that involve frequent carrying of systems, working on-site, etc., and especially in the tensile test applications segment.
For example, electricity companies worldwide use Ron dynamometers for cable and wire tension testing as the lightweight systems enable electricity poles to be climbed easily and safely.

The same need to reach optimal cable tension also exists in other applications where optimal tensioning is important for stabilization of structures. For example: Suspension bridges and structures that are stabilized and supported by guy wires.

HOW TO CHECK TENSION IN A CABLE


How to check tension in a cable without permanently installing a load cell:  




1.  Obtain a tension meter kit which includes:
         a)  an auxiliary cable
         b)  a turnbuckle or cable puller attached to the auxiliary cable
         c)  a Ron Load Cell attached to the auxiliary cable per the manufacturer’s instructions
         This is the tension meter kit.

2.  Using cable grips, attach the tension meter kit, leaving slack, to the fixed cable to be tension tested.

3.  Slowly tighten the tension in the tension meter kit, manually checking the fixed cable for the first signs of slackness.

4.  As soon as the first signs of slackness appear in the fixed cable, the entire load has been transferred to the tension meter kit, and the force will be displayed by the Ron Load Cell.

5.  If the load is less than desired, tighten the turnbuckle on the fixed cable and retest until the desired load is obtained.

6.  If the load is greater than desired, loosen the turnbuckle on the fixed cable and retest until the desired load is obtained.

7.  Remove the tension meter kit.
