Self-regulating heating cable SRL up to 85°C and power up to 31 W/m
Self-regulating heating cable SRL up to 85°C and power up to 31 W/m
For freeze protection or temperature maintenance up to 65°C. For use with pipes, valves, tanks, etc. where the exposure temperature does not exceed 85°C
No risk of overheating or damage to cables during overlapping or insulation penetration
Standard powers: 9/15/24 and 31 W per metre at 10°C (voltage: 230 V)
Section lengths up to 225 metres in length depending on capacity, minimum temperature and circuit breaker type.
A self-regulating cable is a cable whose heating element is a semiconductor matrix. A semiconductor has the property of increasing or decreasing its resistance when the ambient temperature changes. Thus, the cable is able to independently adjust itself to certain temperature conditions; at positive temperatures the cable will heat up less, at minus temperatures it will heat up more, while the change in cable heating temperature is local.
The main advantage of this type of cable is its resistance to possible overheating.
Among the disadvantages: its price, instability to mechanical loads, and fear of moisture. If the outer sheath of the cable is mechanically damaged and moisture enters the semiconductor matrix, the cable fails.
The main application of this type of cable is heating of pipelines and heating of tanks, as well as all kinds of objects where the use of resistive cables is impossible due to the likelihood of overheating and failure.
