Abstract
The utility model relates to a cable with special purposes, specifically to a temperature self-regulated heating cable. The temperature self-regulated heating cable comprises a conductor and a heating element, wherein the conductor is composed of two soft carbon fibres arranged side by side at the cabling structure centre; the outer side of the conductor is wound with the heating element which is made of high polymer with PTC switch performance; an heat resisting insulating layer made of fluoroplastic materials is extruded out of the heating element; a heat conducting and metal shield layer made of annealing soft copper strips is wound out of the insulating layer evenly; an outer protection layer composed of a non-alkaline glass fibre weaving layer and a heat resisting insulating paint layer coated in the non-alkaline glass fibre weaving layer is wound out of the heat conducting and metal shielding layer. The cable has the characteristics of simple structure, high heat efficiency, long service life, stable performance, sensitive response to difference or change of environmental temperature, superior softness, high safety, economical and practical performances, and energy conservation.
Description
Technical field
The utility model relates to the special purpose cable, specifically a kind of self controlled heating cable.
Background technology
Self controlled heating cable is that a kind of temperature sensitivity of self material that relies on is regulated power output automatically, realizes the effect of A.T.C.Very great development has been arranged in recent years, and particularly in Japan, the heating cable of various structures, different materials emerges in an endless stream, and range of application also day by day enlarges.Domestic relevant enterprise also constantly puts out a new product, and mainly is the heat tracing of the equipment such as holding vessel, pipe-line equipment and container that are used in industries such as oil, chemical industry, metallurgy, electric power, water conservancy, light industry, pharmacy.Electric pressure is at 220V.Be applied in civilian warming installation, health care device, household electrical appliance insulation etc. in addition, electric pressure is at 12-60V.This cable common type adopts the alloy silk to do conductor, cause a kind of macromolecule heating as heater element by the current flow heats mode, this cable exists in use that energy resource consumption is big, heating power is unstable, cable useful life is short, heater element is aging easily, harder, the not high defective of the heat efficiency of whole cable, particularly in civilian and medical facilities, these deficiencies are more obvious.
The utility model content
The utility model is intended to solve the problems referred to above that existing cable exists, and a kind of self controlled heating cable of new structure is provided, and it can improve the performance of cable, improves the efficiency of heating surface, improves the useful life and the flexibility of cable.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of self controlled heating cable, comprise conductor, heater element, described conductor is made of the soft charcoal fiber of two parallel placements that place the stranding structure centre, the conductor outside is surrounded with heater element, this heater element is made of the high molecular polymer with PTC switch performance, heater element is extruded with the insulating barrier that one deck is made of resistant to elevated temperatures fluoroplastics material outward, heat conduction and metal screen layer that the wrapped equably one deck in this insulating barrier outside is made of the annealed copper band, this heat conduction and metal screen layer are surrounded with the outer jacket that one deck is made of alkali-free glass wool braid and the high-temperature insulation japanning that is coated with outward outside this alkali-free glass wool braid.
Compared with prior art, the utility model is simple in structure, adopted simultaneously charcoal fiber with suitable volumes resistivity as the high polymer with PTC switch performance of conductor and a kind of novel KT series as heater element, improve heating efficiency and useful life.Temperature control performance is stable under different initial temperatures, and current time constant is little, and programming rate is fast.Adopt the copper strips lapping layer to improve thermal conductance, metal screen layer as cable is that the protective earth that prevents generation of static electricity increases heat transfer and thermolysis simultaneously, and the uniform heat distribution, adopt thermostable fluorine plastics and glass fiber and insulating varnish cable security performance, heat resistance further to be improved as insulation and sheath.In a word, this construction of cable is simple, heat efficiency height, and long service life, stable performance, to the difference or the reacting condition sensitivity of ambient temperature, particularly soft, safe, economical and practical, energy-conservation.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
Among the figure: charcoal fiber conductor 1, heater element 2, insulating barrier 3, heat conduction and metal screen layer 4, outer jacket 5.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to Fig. 1, the described self controlled heating cable of present embodiment, two charcoal fibers of the parallel placement in its cable center position conductor 1, be added with the heater element 2 that one deck is made of the KT series high polymer with PTC switching characteristic two charcoal fiber conductor 1 outsides, extrude the insulating barrier 3 that one deck is made of resistant to elevated temperatures fluoroplastics in heater element 2 outsides, these insulating barrier 3 thickness are even, smooth surface.Insulating barrier 3 outsides are surrounded with one deck equably by the annealed copper band of 0.05mm thickness heat conduction and the metal screen layer 4 as the heat conducting piece, be woven with one deck alkali-free glass wool in the copper strips outside, this glass braid density is not less than 80%, scribble the insulating varnish of the resistant to elevated temperatures environment-friendly type of one deck at the glass fiber skin, form outer jacket 5 with glass fiber, guarantee the useful life and the fail safe of product.In this embodiment, key is to select for use the high polymer of suitable charcoal fiber conductor of resistivity 1 and heating as heater element 2, and select for use and the combination of both materials is to realize the present utility model purpose technological core.
