Our powerheat aht is a unique patented high power high temperature constant wattage cable.
Parallel resistance heating cable.
Measure the resistance of each cable individually and investigate deviations in resistance between parallel conductors.
What are self regulating or power limiting heating cables.
Verify uniform resistance of parallel conductors using a low resistance ohmmeter.
It has an aluminium outer.
Where resistance of the material increases as the operating temperature rises a reduction of heating power occurs.
Apart from the connections some of these parallel electrical heating cables can be immersed into fluids.
Given below are various kinds of tests that are conducted on cables.

Constant power output per meter.
The following tests are type test of electrical power cable.
The parallel resistance configuration allows the cable to be cut to length and terminated in the field with easy to use thermon supplied kits.
Single end power input.
One of the key benefits of parallel heating cables self regulating or constant wattage is the ability to cut the cable to length from a drum on site without the need to consider the resistance of the wire itself.
Constant wattage heating cables as their name suggests are designed to deliver the same power output irrespective of pipe temperature.
Can be cut off the roll.
