2700 Series self-regulating heating cable with fluoropolymer jacket up to 85°C and up to 32 W/m
2700 Series self-regulating heating cable with fluoropolymer jacket up to 85°C and up to 32 W/m
The 2700 Series cables provide freeze protection and process temperature maintenance for fluid handling and storage systems requiring very high levels of heat dissipation or exposure to elevated temperatures.
Cables can be configured for both normal (non-explosive) areas and hazardous (explosive) areas, including locations where exposure to corrosive or organic materials is possible.
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.
