Abstract
The utility model discloses a kind of heating cable, this heating cable comprises two heating cores, oversheath, inner sheath, screening braid, the periphery of heating core is provided with insulating barrier, evenly screening braid is provided with in the outside of insulating barrier, inside is provided with thermal insulation board, thermal insulation board is positioned at the centre of two heating cores, is separated by two heating cores.The oversheath with fan-shaped space that the utility model adopts; while outer protection effect can be ensured; in the outside of sheath, there are fan-shaped heat radiation lattice; heat energy can be distributed as soon as possible; can not at inner stored heat; good heat dissipation effect and service life of cable can be extended; the utility model is rational in infrastructure; long service life; oversheath does not directly contact with heating inner wire; wherein oversheath adopts low smoke and zero halogen oversheath, and during the burning of its superior flame retardant property, pernicious gas is few, and non-corrosiveness gas is overflowed.
Description
Technical field
The utility model relates to a kind of cable, particularly relates to a kind of heating cable.
Background technology
Why heating cable heating is referred to as optimal heating system in winter, is not only its economy, safety, convenience, high-quality, and is that it is using the main body of people as life, highlights theme that is comfortable, healthy, this three large modern life of environmental protection; The human oriented design of height, simply, control mode flexibly, brings great convenience to user; Hidden in underground system architecture, save the interior space to greatest extent.Heating cable take electric power as the energy, carries out by alloy resistance wire the effect that heating power reaches heating or insulation.But the problem that heating cable exists is exactly, due to the existence of oversheath, dispel the heat usually uneven, the effect of heat radiation is bad, and just surface temperature is lower to cause heating cable, causes intensification slower, and local easy overheated wire rod entirety heating, heating ground can not be capped.Once cover, coated region temperature can continue to raise, until exceed safe temperature, damages wire rod, even breaking out of fire.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, a kind of heating cable is provided, there is fire prevention, radiating efficiency is high, uniform feature of dispelling the heat, can prevent from causing hot-spot, the hidden danger of breaking out of fire because heat generating wire cable heating is uneven.
The technical solution of the utility model is: a kind of heating cable, this heating cable is by oversheath, inner sheath, screening braid, heating core composition, it is characterized in that: heating core comprises the heating core and the peripheral insulating barrier arranged that are positioned at center, evenly screening braid is provided with in the outside of insulating barrier, inner sheath is provided with in shielding braid outside, the heat radiation lattice of sector structure are provided with between inner sheath and oversheath, heat radiation lattice are made up of heat-dissipation spacer, described heat-dissipation spacer one end is fixedly connected with inner sheath, the heat-dissipation spacer other end is fixedly connected with oversheath, especially portion of dispelling the heat is provided with external sheath layer, described screening braid inside is provided with dividing plate, dividing plate is positioned at the centre of two heating cores, two heating cores are separated, thermal insulation board two ends and screening braid are mutually permanently connected.
Further, the material of described heating core is nichrome resistance wire or corronil resistance wire.
Further, described insulating barrier is coated with screening braid.
Further, the material of described insulating barrier is magnesia or high density polyethylene (HDPE).
Further, the shape of described oversheath is oval hollow sheath or platypelloid type hollow sheath.
Further, described oversheath adopts low smoke and zero halogen oversheath, and its material is polyolefin or radiation hinge polyolefin.
Further, the cross sectional shape of described heating core is oval or platypelloid type.
Further, described screening braid is Copper Foil braid or aluminium foil braid.
Further, described sheath is the bulkiness glass fibre of coating silicon rubber.
The beneficial effects of the utility model are: a kind of heating cable, comprise bar heating core, oversheath, inner sheath, screening braid, the periphery of heating core is provided with insulating barrier, described heating core is nichrome resistance wire or corronil resistance wire, the resistivity of these two kinds of resistance wires is larger, and intensity and fusing point very high, at high temperature these two kinds of resistance wires are not oxidized and long service life.Be provided with thermal insulation board in described screening braid, this thermal insulation board is positioned in the middle of two heating cores, and dividing plate is the micro-material heat insulating thermal preserving board of nanometer, serves heat insulation function, prevents two cores that generate heat from pressing close to produce the disaster hidden-trouble that high temperature causes.Described screening braid is Copper Foil braid or aluminium foil braid, has effectively masked the interference that electric field is lived to people, serves earth leakage protective effect simultaneously.If insulating barrier is once be destroyed, screen layer is first charged, and when screen layer belt current reaches 30mA, the earth leakage circuit-breaker auto-breaking of its front end, plays a protective role to personal safety.Fan-shaped heat radiation lattice are provided with between described oversheath and inner sheath, heat radiation lattice are made up of multiple heat-dissipation spacer, have and make heating core radiating efficiency high, and heat radiation acts on uniformly, can prevent from causing hot-spot, the hidden danger of breaking out of fire because heat generating wire cable heating is uneven.Described oversheath adopts low smoke and zero halogen oversheath, its superior flame retardant property, and during burning, pernicious gas is few, sheath adopts the bulkiness glass fibre of coating silicon rubber, have and outstanding moltenly spatter resistance, pliability and water resistant oil resistant characteristic, also there is excellent wear-resisting and thermal resistance performance.
