Abstract
The invention discloses a novel geothermal cable, relating to the field of cables. The novel geothermal cable is characterized in that a cable core comprises a conductor and heat conducting film coated outside the conductor; an insulation layer is arranged outside the heat conducting film; a screening layer is wrapped outside the insulation layer; a resistance wire is wound outside the screening layer; the resistance wire is connected with the conductor in the heat conducting film every other 1cm by a through hole, so that heat energy can be favorably conducted; an isolation layer is arranged outside the screening layer; an inner protection layer is arranged outside the cable core; a cavity is formed between the cable core and the inner protection layer, so that the heat energy is favorably and uniformly emitted; a water blocking layer is arranged outside the inner protection layer; an outer protection layer is arranged outside the water blocking layer; and the inner protection layer, the water blocking layer and the outer protection layer together form an outer protection layer of the cable core. The novel geothermal cable has the characteristics of uniformity in heat emission, high heat efficiency, low energy consumption, water blocking, corrosion resistance, high-temperature resistance, no electromagnetic radiation, ageing resistance, no toxic gas generation after heating, a long service life, and being capable of arbitrary cutting.
Description
Technical fieldThe present invention relates to field of cables, specifically relate to the novel terrestrial cable.
Background technologyAlong with the progress of expanding economy with science and technology, also increasingly high to environmental protection requirement, the requirement of original Boiler heating incompatibility environmental protection and energy saving.China recent years begins to adopt Geothermal electric cable to carry out heating; This heating technology adopts underground heating mode; Inteldectualization Indoors management, charging is controlled at the branch family automatically, has noiselessness, no flue dust, no waste gas, conserve space, has a narrow range of temperature, advantage non-maintaining, applied widely.
But there are some shortcomings in the Geothermal electric cable that uses at present: cable laying is at floor, and cable can produce heat after energising; The insulating barrier of existing cable can not be high temperature resistant; The heat that lead produces can burn out cable gradually, causes shorten useful life, can not with the same longevity of building; Even can cause short circuit, influence the operate as normal of heating.In case it is impaired that cable is anti-corrosion, the electromagenetic wave radiation leakage phenomenon can take place, cause harm to human body; Address this problem and to carry out large-area laying again, cause resource and cost waste.In case the phenomenon of flooding occurs, the floor is immersed in the water, and existing cable can not effectively block water, and can leak electricity to connect the dangerous phenomenon of electricity, jeopardizes personal safety.Existing Geothermal electric cable belongs to the measured length Geothermal electric cable, can not cutting in laying installation process, and in order to guarantee specified power, electric heating cable all is with measured length production traditionally.Can't require rationally to cut out according to laying, cause the inconvenience of laying and installing.
Summary of the inventionIn view of the defective that prior art exists, the objective of the invention is to provide a kind of heat radiation even, the heat efficiency is high, and energy consumption is low; Block water, corrosion-resistant, high temperature resistant, electromagnetic-radiation-free; Anti-aging, the no poison gas in back that is heated produces long service life, the environmental protection and energy saving novel terrestrial cable that can cut randomly.
The technical solution that the present invention adopted is: the novel terrestrial cable comprises core, conductor, heat conducting film, insulating barrier, screen, resistance wire, through hole, separator, cavity, sheath, water blocking layer, outer jacket; Core comprises conductor and is coated on the outer heat conducting film of conductor that heat conducting film is provided with insulating barrier outward, lapped shielding layer outside insulating barrier; Outside screen, twine resistance wire; Resistance wire is every to have a through hole to link to each other at a distance from 1cm with the heat conducting film inner wire, is beneficial to the conduction of heat, outside screen, is provided with separator; Core is provided with sheath outward, leaves cavity between core and the sheath, is beneficial to evenly distributing of heat, and sheath is provided with water blocking layer outward, outside water blocking layer, is provided with outer jacket, is made up of the outer protection layer of core jointly sheath, water blocking layer and outer jacket.Core is three and twists combining structure again, is the outside distribution equalizing structure in center.Conductor is that the outer gasification of carbon fiber carbofrax material is processed.Heat conducting film is a polyimide film, and heat conducting film has constant temperature, insulation, the effect of heat conduction.Insulating barrier is processed by gathering PTFE, gathers PTFE and has good heat-conducting.Screen adopts the netted braiding of aluminium one polythene material to form.Separator is a carbon fiber reinforce plastic cloth.Sheath adopts the low smoke and zero halogen cross-linking polyethylene materials, and water blocking layer adopts soft PVDC material.Outer jacket adopts resistant to elevated temperatures mica material.
Because the present invention has heat radiation evenly, the heat efficiency is high, and energy consumption is low, blocks water, and is corrosion-resistant; High temperature resistant, electromagnetic-radiation-free, anti-aging, the no poison gas in back that is heated produces; Long service life, the characteristics that can cut randomly, the scope of application is extensive, is a kind of new product with promotional value.
