The inner core of the heating cable consists of cold and hot wire, and the outer part consists of an insulating layer, a ground layer, a shielding layer, and an outer shell. As for heating cables, single core and double core are most often used. The structure of the single terminal is such that the cable enters from the "cold wire", sequentially connects the "hot wire", and then connects the "cold wire" to the lead. A single-core heating cable is characterized by a "head and tail," both of which are "cold wires" for connecting to a thermostat. The two-core heating cable comes from the "cold wire", connects the "hot wire" in series, and then returns from the "cold wire" in the cable. Its peculiarity is that the head and tail are at the same end.

road snow melting

When the road in front of the house has a large slope, when snow or frost falls in winter, it will be difficult and dangerous for vehicles to rise and descend the slope. If we lay heating cables under the rut of this slope section of the road to melt the snow and ice, then such difficulties and dangers will be effectively resolved. Changchun installed heating cables in the overpass with a slope of 4% and achieved good results. The use of snow melting technology with heating cable on airport runways was relatively extensive and mature.

The melting of snow and ice on the cornices and roofs

Ice and snow will cause serious damage to the roof, and heavy snow will increase the load on the roof of the large-span building and, if it is not melted in time, will cause a dangerous building. On the cornishes during snow melting in the northern regions, there is often ice skating, the length of which sometimes reaches 1 m and weighs more than ten kilograms, and it is very dangerous to break and fall. The roof and cornices can effectively prevent the danger from snow and ice. Civilian buildings suitable for using heating cables for snowmelt roofs include rescue centers, hospital roofs, helipads, glass roofs, flat roofs, large-span structural roofs, simple roofs for pedestrian crossings, roofs (to prevent ice injury), special figured roof, etc.

Heating cables are widely used not only in industry but also in civil buildings and have shown their high viability. Combined with the current engineering situation, heating cables are mainly used in parking lots, equipment floors, elevators in civil buildings insulation of indoor machines, pipe wells, etc. D., as well as snow melting for school wind and snow areas, building roofs, underground garage ramps, etc. D. As this technology improves and people are aware of it, the range of its application in civilian buildings will further expand. It is believed that the application of this technology will bring more safety and comfort to people's lives and will be a new bright spot in the green construction that we advocate for.
