  • Features & Benefits
Product Name:
Low Temperature Self-regulating Heating Cable RSR

Short Introduction:

RSR is ideally used for process temperature maintenance and frost protection of regular diameter pipelines, tanks, valves, flanges, roof & gutter de-icing and other application where low temperature is needed. It is suitable for non-hazardous area, and cable with fluoropolymer outer jacket can also be used in hazardous area and corrosive area. 

In the past 40 years, self-regulating heating cables (heat trace cable) have become very popular all over the world. Self-regulating heating cable can be used for a lot applications like pipe and vessels freeze protection, pipe and tank temperature maintenance, snow melting for roads and walkways, roof and gutter de-icing.

Our Advance:
Three layer co extrusion technology
1)Definition
Three layer co-extrusion technology of self-regulating heating cables is characterized in: the cables consist of two conductive wires with a low resistance transition layers, PTC semi-conductive matrix, inner insulating layer and outer insulating layer, metal braid and outer jacket. Among them the three layers — low resistance transition layer, PTC Semi-conductive matrix and inner insulting layer are extruded in one step.
2)Advantages
A. Owing to three layer co-extrusion technology, the inner insulating layer wrapped the PTC semi-conductive matrix tightly. No gap, no air, no water, no oil and no impurities will contaminate the matrix, which reduces the cable decay rate.
B. Low resistance transition layer contacts the PTC semi-conductive matrix tightly, effectively reducing the current impact to the material of PTC, reducing the start current, prolonging service life.
C. Because of the special nature of PTC semi-conductive matrix, almost all of the insulating material on the market will damage the PTC semi-conductive matrix more or less. The insulating material and PTC semi-conductive matrix we are using are made by our own exclusive technology. The insulating material can match the PTC semi-conductive matrix perfectly and doesn't cause any damages to the semi-conductive matrix.
3)Material properties:
Excellent resistance to weather and ultraviolet radiation. 
High and low temperature resistance, -50°C — +140°C.
Great insulating property. 2000MΩ per 100 meters.
4)Process

The three layer with double insulation extrusion technology (the world's first) with the tropics, forming a two insulating layer of the production process in the three layer of the application with the extrusion technology, three layer with double insulation extrusion technology to improve the insulation performance with the tropics, increased mechanical strengthen extend the service life.
