Self Regulating Heat Tracing Cable

Short Description:

LSR self regulating heating cable is an exceptional heating cable. Constructed of a semi-conductive heater polymer(also named as “PTC”) extruded between parallel bus wires with the addition of insulation layer. Suitable for both metal and non-metal piping systems, storage tanks and equipment to provide anti-freeze protection, except for those of of steam purging.

As for the application of electric heat tracing, it may be known that it is the most effective and advanced method to maintain the process temperature of liquid storage medium tanks and infusion pipes for heat tracing, heat preservation, antifreeze and anticoagulation of pipes, valves, pumps, tanks and tank solvents in chemical, electric power, machinery, shipping, petroleum, pharmaceutical and other industries. Electric heat tracing is not only suitable for steam heat tracing places, but also can solve the difficult problems of steam heat tracing.


heating cable

LSR self regulating heat tracing cable is an exceptional heating cable. In each heat tracing wire, the number of circuits between the busbars varies with the temperature. When the temperature around the electric heat tracing wire becomes cold, the conductive plastic will shrink the micro molecules to connect the carbon particles to form a circuit, and the current will pass through these circuits to heat the electric heat tracing wire.


LSR-J is the basic low temperature heating cable type, with the Max.maintain temperature up to 65℃(149°F), while the Max.exposure temperature is 85℃ (185°F). Generally used in places where there is no explosion-proof or anti-corrosion requirements, and the environmental humidity is not high.

LSR-P/F is enhanced with an additional aluminum-magnesium alloy braid(tinned cooper for option), sheathed by a fluoropolymer out jacket. Compared to LSR-J, it has a good performance on anti-corrosive, also with characteristic of explosion-proof, ideal for places with explosion-proof requirements, especially chemicals, power supply and other places need corrosion resistance.

1. Energy saving: Due to the unique PTC property, the cable adjust the output power respond to ambient temperature.

2. Easy installation: PTC semi-conductive matrix is composed of the infinite parallel connection of carbon particles, allowing it to be cut into the exact length required.

3. Long service life: A lower starting current and attenuation rate ensures our cables provide you a longer service life.

4. Safety for use: Can be overlapped by themselves without the danger of overheat or burnout.

5. High quality with low cost: self- regulating, easy operation, low cost to maintain. No recycled material used, all the components are manufactured by our own factory, which means better quality and competitive cost for you.
