Where resistance of the material increases as the operating temperature rises a reduction of heating power occurs.
Parallel resistance heating cable.
Constant wattage heat tracing cables advantages.
It has an aluminium outer.
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.
Apart from the connections some of these parallel electrical heating cables can be immersed into fluids.
Single end power input.
Can be cut off the roll.
Fp parallel resistance constant watt heating cables are de signed to provide freeze protection or process temperature maintenance to piping tanks and equipment.

What are self regulating or power limiting heating cables.
Measure the resistance of each cable individually and investigate deviations in resistance between parallel conductors.
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.
Given below are various kinds of tests that are conducted on cables.
We produced the world s first parallel resistance cut to length heating cable in 1978.
Our powerheat aht is a unique patented high power high temperature constant wattage cable.
