Middle Temperature Self-regulating Heating Cable HWSR

Middle Temperature Self-regulating Heating Cable HWSR is design for hot water temperature maintain,when hot water taps are infrequently used,the water stay in the distribution pipework cools and is usually run to waste before hot water from the storage cylinder arrives at the tap. We have two types of HWSR cable,one can maintain the temperature around 50°C to 60°C,another can up to 70°C.Our HWSR cable max exposure temperature is 120°C.

Product Name:
Middle Temperature Self-regulating Heating Cable HWSR

Short Introduction:

Middle Temperature Self-regulating Heating Cable HWSR is design for hot water temperature maintain,when hot water taps are infrequently used,the water stay in the distribution pipework cools and is usually run to waste before hot water from the storage cylinder arrives at the tap. We have two types of HWSR cable,one can maintain the temperature around 50°C to 60°C,another can up to 70°C.Our HWSR cable max exposure temperature is 120°C.

The self-regulating heating cable (self-regulating heating cable and auto temperature control heating cable) is a new generation and the only constant temperature electric band heater. The resistivity of the heating element is of extremely high “PTC” (positive temperature coefficient) and these elements are in parallel connection. The characteristics are as follows: it can automatically restrict the heating temperature, and can automatically adjust the output power with the temperature of the heated body with no need of any other additional equipment; it can be cut or connected in a certain length at free will for use, and allows multiple overlapping with no high temperature hot spots or worry about being burnt up. By right of these characteristics, heating cables are provided with advantages including overheating prevention, convenient usage and maintenance as well as energy saving. They are applicable for temperature control, heat trace, insulation and heating of pipes, equipment and containers, especially there is any material easy to break down, deteriorate, crystallize or condense and freeze. They have been widely used in industries including petroleum, chemical industry, power, metallurgy, light industry, foods, freezing, buildings, coal gas, production and processing of agricultural byproducts as well as other departments.

Our Advance:
Three layer co extrusion technology
1)Principle
Three layer co extrusion technology of self regulating heating cables, which is characterized in that: two metal wire coated with a low resistance layer, a conductive layer, insulating layer and the insulating layer, a metal shielding net. Among them low resistance layer, conductive layer and the insulating layer of the three layer of a extrusion. 
2)Advantages
The two metal wire coated with new low resistance layer, the insulation layer of the conductive layer, forming a three layer with the extrusion production process, the conductive layer and the insulating layer structure closely No gap, no air, no impurities, reducing self heating single fault rate and decay rate, convenient and safe, long service life.
Due to low resistance between the transition layer and the PTC contact closely, effectively reduce the starting current, the current impact to the material of PTC, prolong service life, reduce the 3)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.
4)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.
5)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.
