Abstract
The utility model discloses a temperature resistant environmental friendly double-conductor heating cable, comprising two heating conductors which are parallelly disposed, and an insulating layer is disposed outside the two heating conductors by extrusion molding. The periphery of the insulating layer is provided with a ground lead. The ground lead is formed by braiding anaerobic tinned copper wires. A shielding layer is disposed outside the ground lead. An outer sheath layer is disposed outside the insulating layer by extrusion molding. The cable is reasonable in structural design. A cable core is formed by two parallel high-performance copper-based alloy wires or nichrome wires. Linear resistance of the material is uniform and stable, and is high in control precision. Compared with a single-conductor heating cable, the double-conductor structure is small in inductance eddy, and is stable and reliable in heating power. In addition, the cable has good high-temperature resistance, and is environmental friendly, soft, and has bending resistance performance.
Description
Technical field:
The utility model relates to line cable technology field, relates in particular to the two heating cables of leading of a kind of heatproof environmental protection.
Background technology:
Along with the development of society, the progress of science and technology, traditional heating mode can't satisfy the heating theory of people's safety, environmental protection.Heating cable heating is a kind of environment friendly and pollution-free, safety, economy, occupy that the space is few, shelf life long, be convenient to control heating mode.Be widely used in the heating of conveyance conduit or the container of oil, chemical engineering industry, civilian, commercial, agriculture etc. have a place that heating requires, and can be installed on any occasion that needs underground heat, comprises bathroom, kitchen, bedroom etc.; Can be layed in different ground, under the materials such as floor tile, floor, ceramic tile, woollen blanket, cement, asphalt surface.
Existing heating cable generally adopts heating conductor, crosslinked polyetylene insulated PVC sheath material, in use the defective such as poor, not environmental protection of low, the anti-soft bendability of high temperature resistant grade.
The utility model content:
In order to remedy the prior art problem, the purpose of this utility model provides that a kind of heatproof environmental protection is two leads heating cable, and reasonable in design has well high temperature resistant, environmental protection, softness, resistance to bend(ing) energy.
The technical solution of the utility model is as follows:
The two heating cables of leading of heatproof environmental protection, comprise two heating conductors, it is characterized in that: described two parallel placements of heating conductor also have insulating barrier in outside extrusion moulding, the insulating barrier periphery is provided with earth connection, earth connection is that the zinc-plated soft copper silk braiding of anaerobic consists of, earth connection is provided with screen outward, and the outer extrusion moulding of screen has external sheath layer.
Described heatproof environmental protection is two leads heating cable, it is characterized in that: described two heating conductors adopt acid bronze alloy silk or nichrome wire.
Described heatproof environmental protection is two leads heating cable, and it is characterized in that: described insulating barrier adopts 125 ℃ of high resistance irradiation second third materials.
Described heatproof environmental protection is two leads heating cable, it is characterized in that: it is that the braiding of 0.29mm tinned copper wire consists of that described earth connection adopts 16 diameters.
Described heatproof environmental protection is two leads heating cable, it is characterized in that: described screen employing aluminium-plastic tape is wrapped to weave double-decker with tinned copper wire.
Described heatproof environmental protection is two leads heating cable, and it is characterized in that: it is flame retardant polyurethane that described external sheath layer adopts material.
The utility model has the advantages that:
1, cable core adopts two high performance copper-based alloy silks that are arranged in parallel or nichrome wire to form, and the linear resistance of material is uniform and stable, and control precision is high, and two guide structures compare with singly leading heating cable that to have an inductance eddy current little, and heating power is reliable and stable.
2, insulating barrier adopts 125 ℃ of high resistance irradiation second third materials, not only electric property is good, the feature of environmental protection is high, and higher than general heating cable temperature resistant grade, and serviceability temperature can reach 125 ℃ continuously, mechanical strength does not reduce yet, and has greatly strengthened the useful life of cable.
3, the restrictive coating materials'use high, the soft resistance to bend(ing) of intensity, cold resistance, resistance to wear, radiation hardness, and the equal outstanding TPU polyurethane jacket of the properties such as low temperature resistant, surface temperature is 100 ℃ under its cable carpet after tested, 48 ℃ of carpet surface temperature, the thick end of carpet is 10mm, experimental period be 180 days 24 hours uninterrupted, high-temperature resisting heating cable is still working on.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
The two heating cables of leading of heatproof environmental protection, comprise two heating conductors 1, two heating conductor 1 parallel placements also have insulating barrier 2 in outside extrusion moulding, insulating barrier 2 peripheries are provided with earth connection 3, earth connection 3 is that the zinc-plated soft copper silk braiding of anaerobic consists of, be provided with screen 4 outside the earth connection 3, screen 4 outer extrusion moulding have external sheath layer 5.
Two heating conductors 1 adopt acid bronze alloy silk or nichrome wire.
It is that the braiding of 0.29mm tinned copper wire consists of that earth connection 3 adopts 16 diameters, has corrosion-resistant by force, and drainage effect is good.
It is flame retardant polyurethane that external sheath layer 5 adopts materials, even improve the anti-flammability of cable and cold resistance, resistance to wear, radiation hardness, resistance to bend(ing), and low temperature resistant under subzero 30 degrees centigrade of cryogenic conditions, still can keep its pliability.
