Low Temperature Self-regulating Heating Cable MSR




Short Introduction:

MSR Self-regulating heating cable is mostly used for inner pipe or outer side pipe frost protect. Especially our MSR-PF have Teflon outer jacket, the Teflon outer jacket have NSF certificate, it can be used for drinking water. 

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 Advantages:

Three layer co-extrusion technology

1. Conductor
2. Low resistance transition layer
3. PTC Semi-conductive
4. Inner insulation layer
5. Outer insulation layer
6. Metal braid
7. Outer jacket


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. Most of out-sourcing insulation resin will damage the PTC matrix on the performance such as life-span and insulation safety. Huanrui improved it by using self-made special modified insulation resin, the resin matches the PTC well and avoids the damaged to both layers, with longer life-span and higher performance. 

D. Low starting current

The inner insulation layer using the self-made insulation, due to the special nature of PTC material, the market most of the insulation of PTC will be more or less damage, and we use a unique formula of self insulation, insulation itself does not have any damage to the PTC, Between the insulation and PTC is compact in structure, can effectively waterproof. In addition to our self insulation and good weather resistance, low temperature resistance, high temperature, anti ultraviolet radiation.
E. Safety
The traditional production process of self regulating heating cables between the combination does not close, the air and impurities are not fully discharged, electric heating at high temperature for a period of time it caused by the metal electrode and the PTC heating element.

The contact surface of the separation failure, resistance caused by fire, with three layers of extrusion technology development and application, effectively put an end to these potential risks, to avoid the fire, security.

F. Material properties
Excellent weather resistance and ultraviolet radiation. 
High and low temperature resistance, -50°C—140°C.
Great insulating property. 2000MΩ per 100 meters. 

3.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, increase mechanical strengthen extend the service life.
