Abstract
The utility model relates to a heat-accumulation heating cable, consisting of an oversheath, shielding braid layers, two inner insulating layers and two heating internal conductors. Two circular inner insulating layers are arranged in the oversheath. Two heating internal conductors are respectively wrapped inside the inner insulating layers. At least one shielding braid layer is mounted between each inner insulating layer and the oversheath. The advantages are that the heat-accumulation heating cable provided by the utility model is reasonable in a structure and long in useful life, the oversheath doesn't directly contact with heating internal conductors and adopts a low-smoke non-halogen oversheath, the fire retardation performance of the oversheath is superior, limit of smoke is very little when in burning without escaping corrosive gas.
Description
Technical field
The utility model relates to a kind of heating cable, particularly a kind of heat accumulating type heating cable.
Background technology
The heating system that heating cable is used in heating system such as indoor heating system, pipeline tracing system, outdoor ice-melt snow system, roof and roof gutter ice dissolution system, factory building and hangar and is applied to football field, lawn, flower bed etc.But, because heating cable is by its lead heating heating, lead after energising, the one, can produce heat, the 2nd, generate an electromagnetic field simultaneously, if the insulating barrier of lead can not be high temperature resistant, the heat that lead produces may burn out cable, produces very serious consequence; Electromagnetic field is harmful in addition; Live in the meeting influence very big in the electromagnetic field for a long time to people's healthy generation; Though Geothermal electric cable in the market designs in the battery shielding, still there is electromagenetic wave radiation to leak, still manpower health is exerted an influence.The sizing material of surrounding materials such as Geothermal electric cable jacket material of existing market all halogen-containing (F, Cl, Br, I, At) and plumbous cadmium chromium mercury is processed in addition, its burning or can send toxic smog when receiving high temperature.
Summary of the invention
The purpose of the utility model is exactly the weak point in the background technology, and a kind of heat accumulating type heating cable is provided.
For achieving the above object; The utility model adopts following technical scheme: a kind of heat accumulating type heating cable; Constitute by oversheath, screening braid, inner insulating layer and heating inner wire; Oversheath is built-in with two circular inner insulating layers, is enclosed with the heating inner wire in the inner insulating layer respectively, is equipped with one deck screening braid at least between each inner insulating layer and the oversheath.
For a kind of optimization of the utility model, said oversheath adopts the low smoke and zero halogen oversheath.
For a kind of optimization of the utility model, said inner insulating layer is a polyethylene layer.
For a kind of optimization of the utility model, said heating inner wire is an alloy resistance wire, and its cross section of adopting comprises circle or flat flat.
For a kind of optimization of the utility model, said oversheath is circular hollow sheath or flat flat hollow sheath, is provided with the insulation filling layer between each insulating barrier and the screening braid.
For a kind of optimization of the utility model, each inner insulating layer is coated with the inner shield braid outward respectively.
The utility model is compared with background technology, have rational in infrastructure, long service life, oversheath directly contact with the heating inner wire, oversheath employing low smoke and zero halogen oversheath wherein, its fire resistance is superior, smoke intensity is very few during burning, the effusion of non-corrosiveness gas.
Description of drawings
Fig. 1 is the schematic cross-section of heat accumulating type heating cable (adopting flat flat hollow oversheath).
Fig. 2 is the schematic cross-section of heat accumulating type heating cable (adopting circular hollow oversheath).
Embodiment
Embodiment 1: with reference to Fig. 1 and 2.The heat accumulating type heating cable; Constitute by oversheath 5, screening braid 4, inner insulating layer 2 and heating inner wire 1; Oversheath 5 is built-in with two circular inner insulating layers 2; Be enclosed with respectively in the inner insulating layer 2 between heating 1, two inner insulating layer 2 of inner wire and the oversheath 5 and be equipped with one deck screening braid 4 at least.Said oversheath 5 adopts the low smoke and zero halogen oversheath.Said inner insulating layer 2 is a polyethylene layer.Said heating inner wire 1 is an alloy resistance wire, and its cross section of adopting comprises circle or flat flat.Said oversheath 5 is circular hollow sheath or flat flat hollow sheath, is provided with insulation filling layer 6 between each inner insulating layer 2 and the screening braid 4.Each inner insulating layer 2 outer inner shield braid 3 that are coated with respectively.Above-mentioned inner insulating layer 2 or insulation filling layer 6 also need pass through irradiation technique and handle; Binding force between the macromolecule that makes inner insulating layer or insulation filling layer 6 after the radiation treatment strengthens greatly, and then strengthens thermal stability, anti-flammability, chemical stability, anti-drip property, intensity and the stress crack resistant of inner insulating layer 2 or insulation filling layer 6.
Foregoing has combined accompanying drawing that the embodiment of the utility model has been carried out exemplary description, and obviously the utility model is not limited thereto, and the various remodeling that in the utility model scope, carry out all fall in the protection range of the utility model.
