Middle Temperature Self-regulating Heating Cable SSR

Middle Temperature Self-regulating Heating Cable SSR

Introduction

SSR self-regulating heating cables provide the most versatility in heat trace designs and applications. Constructed of a semi-conductive heater matrix extruded between parallel bus wires, a self-regulating cable adjusts its output to independently respond to ambient temperatures all along its length. As temperature increases, the heater’s resistance increases, which lowers the output wattage. Conversely, as the temperature decreases, the resistance decreases and the cable produces more heat. So thermostat is not necessary in some applications. It will never overheat or burnout even when overlapped. The cable can also be cut to any length. As the result, we got an energy efficient heating cable.

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.
