Description
Technical field
The utility model relates to electric and electronic technical field, is specifically related to a kind of heating cable.
Background technology
Heating cable is taking electric power as the energy, utilizes alloy resistance wire to carry out heating power, reaches a kind of construction of cable of heating or heat insulation effect.Heating cable inner core is made up of cold line hot line, and outside is made up of insulating barrier, ground connection, screen and oversheath.After energising, hot line heating, and move in the temperature range of 40 DEG C～60 DEG C, be embedded in the heating cable in packed layer, heat energy is passed to heated body by heat conducting mode and the far-infrared thermal radiation mode of the 8um～13um sending.Because thermal source is cable itself, therefore work long hours under hot environment, exert an influence for wire rod itself and the wrapped material of wire rod unavoidably, when serious, when occurring, in the situation of fire alarm, may to produce a large amount of noxious substances, be detrimental to health, contaminated environment.
Utility model content
The purpose of this utility model is, a kind of environment-friendly type heating cable is provided, and solves above technical problem.
The technical problem that the utility model solves can realize by the following technical solutions:
Environment-friendly type heating cable, comprises cable core, is provided with successively insulating barrier, screen and restrictive coating outward at described cable core, it is characterized in that, the low smoke and zero halogen restrictive coating that described restrictive coating adopts low smoke and zero halogen material to make.
The utility model is by arranging low smoke and zero halogen restrictive coating, makes in the time there is the dangerous situations such as fire alarm, and the toxic smog that can not distribute after by calcination because of sheath and cause environment to be polluted, personnel health suffers damage.
The cable core that described cable core adopts copper alloy silk to make, has and heats soon while making cable work, the advantage that heat-conductive characteristic is good.
The insulating barrier that described insulating barrier adopts fluoroplastics to make.Fluoroplastics have the performances such as excellent dielectric property and resistance to chemical attack, high-low temperature resistant, waterproof, sticky, low-friction coefficient, good self lubricity.At present, be widely used in the industrial circles such as chemical industry, electronics, electric, Aeronautics and Astronautics, semiconductor, machinery, weaving, building, medicine, automobile, the insulating barrier made from fluoroplastics, can effectively protect cable core.
The copper strip shielding layer that described screen adopts copper strips to make.In the utility model use procedure, due to the effect of electric current, can around cable core, form magnetic field, if exceeding 100 micro-teslas, electromagnetic field will impact health and other electrical equipment, by copper strip shielding layer is set, electromagnetic field is limited in core, makes it to be diffused into outside; Meanwhile, screen made of copper is also conducive to increase mechanical strength and the tensile strength of whole cable, extends its useful life.
Between described screen and described insulating barrier, be provided with a lapping layer, the glass tape lapping layer that described lapping layer adopts a glass fibre to make, the lapping layer of making by glass fibre is set, is improved the safety in utilization of cable.The glass tape lapping layer that the utility model adopts glass fibre to make, increase the tensile strength of cable entirety, make cable be not easy wrinkling in transport and installation process and fractureed, resistance to sulfuration, the smokeless halogen-free characteristic nontoxic and that do not fire of glass fibre has also increased cable fail safe in use greatly simultaneously.
Described cable core is at least provided with two, the outside of arbitrary described cable core be respectively equipped with one described in insulating barrier, the cross section of at least two described cable cores is after word order in outside successively to lapping layer, described screen and described restrictive coating described in outer wrapping;
Fill by inserts in space after at least two described cable cores are arranged mutually and between described lapping layer.
Beneficial effect: owing to adopting technique scheme, the utility model not only has excellent mechanical strength and tensile characteristics, also possesses environmental-protecting performance, can not discharge because of the impact of environment for use poisonous and harmful substance, has higher safety in utilization.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is another kind of structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with further elaboration the utility model of concrete diagram.
With reference to Fig. 1, environment-friendly type heating cable, comprises the cable core 1 that copper alloy silk is made, and is provided with successively insulating barrier 2, lapping layer 3, screen 4 and restrictive coating 5 outside cable core 1, and restrictive coating 5 adopts low smoke and zero halogen material to make.The utility model is by arranging low smoke and zero halogen restrictive coating, makes in the time there is the dangerous situations such as fire alarm, and the toxic smog that can not distribute after by calcination because of sheath and cause environment to be polluted, personnel health suffers damage.
The cable core 1 that copper alloy silk is made has and heats soon while making cable work, the advantage that heat-conductive characteristic is good.Insulating barrier 2 adopts fluoroplastics to make.Fluoroplastics have the performances such as excellent dielectric property and resistance to chemical attack, high-low temperature resistant, waterproof, sticky, low-friction coefficient, good self lubricity.At present, be widely used in the industrial circles such as chemical industry, electronics, electric, Aeronautics and Astronautics, semiconductor, machinery, weaving, building, medicine, automobile, the insulating barrier made from fluoroplastics, can effectively protect cable core.Screen 4 adopts copper strips to make.In the utility model use procedure, due to the effect of electric current, can around cable core, form magnetic field, if exceeding 100 micro-teslas, electromagnetic field will impact health and other electrical equipment, by copper strip shielding layer is set, electromagnetic field is limited in core, makes it to be diffused into outside; Meanwhile, screen made of copper is also conducive to increase mechanical strength and the tensile strength of whole cable, extends its useful life.Lapping layer 3 adopts glass fibre to make, and the lapping layer 3 of making by glass fibre is set is improved the safety in utilization of cable.The glass tape lapping layer that the utility model adopts glass fibre to make, increase the tensile strength of cable entirety, make cable be not easy wrinkling in transport and installation process and fractureed, resistance to sulfuration, the smokeless halogen-free characteristic nontoxic and that do not fire of glass fibre has also increased cable fail safe in use greatly simultaneously.
