Abstract
The invention discloses a heat tracing cable for large-space roof de-icing, comprising a copper-nickel alloy wire, a tinned copper wire, a main insulation layer, a ground wire, an inner sheath, and an outer sheath. The surfaces of the copper-nickel alloy wire and the tinned copper wire are coated with a filling layer. The main insulation layer is arranged on the outer surface of the filling layer. A heating wire, a shielding layer, the inner sheath, a water-resistant layer, a braided mesh layer, and the outer sheath are sequentially arranged on the outer surface of the main insulation layer. The heat tracing cable is arranged to melt ice on roofs through heat conduction so as to reduce the stress on roofs, improve the safety performance of houses and reduce the production of ice pitons. By arranging the heating wire, the conductivity of heat is improved, the heating effect of the cable is increased, and power is saved. By arranging the water-resistant layer and the braided mesh layer, permeation of water to the cable can be reduced. The heat tracing cable of the invention is simple in structure and convenient to install. The temperature of a heat tracing pipeline is uniform, so that the heat tracing pipeline is not overheated, and is safe and reliable.
Description
Technical field
The present invention relates to field of cables, particularly relate to a kind of accompanying-heat cable for my face snow melt of large bay.
Background technology
Along with the development of society, cable is universal every field, also applies more and more widely and family, in the area of the long-term severe snow of China, because continuous snowfall causes that roof is large-area leaves accumulated snow, these accumulated snow have great bodily injury for house, can press the house that collapses time serious, and thaw along with accumulated snow, roof four weekly assembly produces ice piton, also can produce injury to human body time serious, therefore, the problem solving this class seems particularly important.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of accompanying-heat cable for the snow melt of large bay roofing, by accompanying-heat cable to external world heat conduction thick snow is melted, to solve the harm of existing snowfall to roof and people.
In order to solve the problem, the invention provides a kind of accompanying-heat cable for the snow melt of large bay roofing, include Contra wire, tinned copper wire, main insulating layer, earth connection, inner sheath and oversheath, described Contra wire and tinned copper wire Surface coating have packed layer, the outside of described packed layer is provided with main insulating layer, and the outer surface of described main insulating layer is provided with heating wire, screen, inner sheath, water blocking layer, woven mesh layer and oversheath according to this.
Further improvement is: the outer surface of described Contra wire is coated with crosslinked polyetylene insulated layer, and the outer surface of described tinned copper wire is coated with conducting plastics layer.
Further improvement is: be provided with tension muscle between described oversheath and woven mesh layer.
Further improvement is: be provided with glass layer between described inner sheath and water blocking layer.
The invention has the beneficial effects as follows: by being provided with accompanying-heat cable, heat transfer snow melt is carried out to the accumulated snow on roof, that reduces roof bears dynamics, to improve the security performance in house, and reduce the generation of ice piton, the conductibility of heat can be improved by being provided with heating wire, increase the heating effect of cable, simultaneously can saves energy, and by being provided with water blocking layer and woven mesh layer can reduce the infiltration of ponding to cable.Structure of the present invention is simple, and easy for installation, heat traced pipeline homogeneous temperature, can not be overheated, safe and reliable.
