  • INQUIRY
Mineral insulated self-regulating cable is composed of conductive polymer, two parallel metal wires and insulation sheath. Suitable for temperature control, heat tracing, heat preservation and heating of pipes, equipment and containers, especially when materials are easy to decompose, deteriorate, crystallize, condense and freeze. Mineral insulated self-regulating cable is widely used in petroleum, chemical industry, electric power, metallurgy, light industry, food, freezing, construction, gas, agricultural and sideline products production, processing and other sectors.

Within Mineral insulated self-regulating cable each hot wire, the number of circuits between bus lines varies with the influence of temperature. When the temperature around the hot wire cools, the conductive plastic produces the contraction of micro molecules and the carbon particles connect to form circuits.

self-regulating cable

As the temperature rises, the conductive plastic expands with tiny molecules, and the carbon particles gradually separate, causing circuit terminals to rise in resistance, which automatically reduces the power output.
As Mineral insulated self-regulating cable the temperature cools, the plastic reverts to a state of micromolecular shrinkage, and the carbon particles connect accordingly, forming circuits that rise automatically with the tropical heat.
Self-limiting temperature tracing has the advantage that other heat tracing equipment does not have. The temperature it controls is neither too high nor too low, because the temperature is automatically adjusted.
Since the heat tracing cable power varies with the temperature at various points in the electrical wake, the heated semiconductor core material behaves as a variable temperature resistance contrary to the trend of high/low heating temperature. Self-limiting electric wake will not overheat even if overlapped. No special design is required. The self-limiting electric tracing cable can be cut at any time in the field to exactly correspond to the actual laying length of the pipeline.
