Service of pipelines and various surfaces in winter time is complicated by considerable difference of temperatures. Consequences of it result in considerable wear of these systems. An optimal option allowing to protect communications from congestions of frost, freezing of the environment and formation of condensate is heating by means of electrical wire. The single-core heating cable is an inexpensive and effective tool for maintenance of the necessary temperature and elimination of frost.
In comparison with heating cables which have two or three cores the single-core product has a number of advantages:
The electrical wire with one core effectively warms space, having section with rather small area. It can be crucial parameter if it is necessary to warm objects with minimum sizes.
The resistive cable transfers electric energy into thermal by means of own resistance. The core of such product possesses constant characteristics. Feature of a resistive heating wire is stable thermal emission. In case of increase in tension it starts to generate more heat, however it is required to observe certain technical requirements for prevention of damage of the line of the heating cable. The section with specific thermal emission is chosen depending on length of the warmed object on the basis of the specification. Independent change of length of section is forbidden as it will affect technical characteristics of the heating cable.
When installing a single-core resistive heating electrocable it is necessary to consider that both ends of section have to be connected to a current source. When laying it is necessary to avoid overlaps as it can lead to overheating and failure of the whole section.
It is effectively used for:
A wide choice of electrocables for heating systems is presented inthe ‘‘Teplovye Sistemy’’ catalog. It is possible to buy everything in Moscow and other cities of the Russian Federation.
