Abstract
The utility model discloses a snow melting cable for a roof, which comprises a hot line, a cold line, a wrapping layer, a master insulating layer, a grounding line, a shielding layer and a sheath layer. The hot and cold lines are positioned in the wrapping layer. The master insulating layer is arranged outside the wrapping layer. The grounding line and the master insulating layer are arranged in the shielding layer and the grounding line is arranged outside the master insulating layer. The sheath layer is arranged outside the shielding layer. The hot line is composed of heating alloy wires, a Teflon insulating layer, an FEP insulating layer and a PTEF insulating layer, wherein the Teflon insulating layer, the FEP insulating layer and the PTEF insulating layer are sequentially coated on the outside of the heating alloy wires. The cold line is composed of conductive copper wires and a conductive insulating layer wrapped outside the conductive copper wires. According to the technical scheme of the utility model, the long-term outdoor severe environment and the production cost are comprehensively considered. Therefore, the snow melting cable can be adapted to outdoor environments in areas larger in snowfall and higher in UV intensity and is good in roof snow-melting effect.
Description
Technical field
The utility model relates to cable product technical field, is specifically related to a kind of roof snow melt cable.
Background technology
Heating cable, is to make the construction of cable, take electric power as the energy, utilizes alloy resistance wire to carry out heating power, reaches a kind of product of the effect of heating or insulation.After heating cable energising, between the temperature of 40～60 ℃, move, and the mode of heat energy being conducted to (convection current) by heat is passed to heated body with the far-infrared radiation mode of the 8～13um sending.By can effectively preventing that at roofing heating cable roof accumulated snow from causing building damage, the snow melt cable that is layed in roof need to consider long-term outdoor adverse circumstances and production cost and structure reasonable in design.
Summary of the invention
The purpose of this utility model is to provide a kind of roof snow melt cable, considers long-term outdoor adverse circumstances and production cost, can adapt to the regional outdoor environment that ultraviolet ray is strong, snowfall is larger, obtains good roof snow melt effect.
To achieve these goals, the technical scheme the utility model proposes is:
A snow melt cable, comprises hot line, cold line, lapping layer, total insulating barrier, earth connection, screen, restrictive coating; Described hot line and described cold line are positioned at described lapping layer, described total insulating barrier is positioned at outside described lapping layer, described earth connection and described total insulating barrier are positioned at described screen and described earth connection is positioned at outside described total insulating barrier, and described restrictive coating is positioned at outside described screen; Described hot line comprises Exothermal Alloys silk and is wrapped in successively Teflon insulating barrier, polyfluorinated ethylene insulating barrier, the teflon insulation layer outside described Exothermal Alloys silk, and described cold line comprises conductive copper wire and is wrapped in the conduction insulating barrier outside described conductive copper wire.
As the further improved roof snow melt cable of the utility model, described restrictive coating is that black polyolefine material is made.Described structure can make roof snow melt cable anti-ultraviolet property strengthen, thereby has increased the useful life of cable.
As the further improved roof snow melt cable of the utility model, described total insulating barrier is that self-crosslinking ambroin is made.
As the further improved roof snow melt cable of the utility model, in described lapping layer and be positioned at described hot line and described cold line is outside equipped with packed layer, described packed layer is that heat conduction carbon fibre material is made.Described structure can improve the mechanical strength of cable, thereby increases the useful life of cable; And contribute to electric cable heating heat conduction.
Snow melt cable in roof provided by the utility model, considers long-term outdoor adverse circumstances and production cost, can adapt to the regional outdoor environment that ultraviolet ray is strong, snowfall is larger, obtains good roof snow melt effect.
