Abstract
The utility model discloses a flat ribbon provided with reinforced steel wires in an inner side of an outer sheath. The flat ribbon heater comprises three conductive cores, which are in a parallel arrangement; three first insulation layers and three second insulation layers, which are disposed on the outer sides of the conductive cores in a wrapped manner. The outer sides of the conductive cores are wrapped by an inner sheath, and a filler layer is disposed between the conductive cores and the inner sheath in a filled manner. The outer side of the inner sheath is provided with a metal shielding layer in a wrapped manner, and the outer side of the metal shielding layer is provided with the outer sheath in the wrapped manner. The inner side of the outer sheath is provided with the reinforced steel wires. The inner sheath and the outer sheath adopt the inflaming retarding polyolefin materials. The flat ribbon heater is advantageous in that the inner side of the outer sheath is provided with the reinforced steel wires, and the strength of the ribbon heater can be greatly enhanced, and the stressed parameter can be optimized; the ribbon heater cannot be broken even when being used overhead for a long time, and therefore the equipment safety can be guaranteed, and the economic losses of the enterprises can be reduced.
Description
Technical field:
The utility model relates to field, ribbon heater, relates in particular to the flat ribbon heater that is provided with reinforcement steel wire in a kind of oversheath.
Background technology:
Heat tape, because it is safe and reliable, purposes is wide, free from environmental pollution, the life-span is long, is widely used in pipeline, the tracing thermal-insulating of storage tank, the anti-freezing, antifreeze of the industrial enterprises such as oil, chemical industry, iron and steel, electric power; Generally be applicable to general area, hazardous area and corrosion region.But it is aerial heat tape need to be arranged on to height in some occasion, because the reason time of deadweight has been grown the easily sagging fracture of appearance of ribbon heater, bring direct economic loss to enterprise.Therefore imagination provides a kind of new construction to solve this problem.
Utility model content:
The purpose of this utility model is just to provide the flat ribbon heater that is provided with reinforcement steel wire in a kind of oversheath, solve in some occasion and heat tape need to be arranged on to height in the air, because the reason time of deadweight has been grown the easily sagging fracture of appearance of ribbon heater, bring the problem of direct economic loss to enterprise.
The technical solution adopted in the utility model is:
In a kind of oversheath, be provided with the flat ribbon heater of strengthening steel wire, comprise conductor wire core: conductor wire core is three copper cash that are arranged in parallel, every copper cash is all enclosed with the first insulating barrier and the second insulating barrier outward, conductor wire core is wrapped with inner sheath, between conductor wire core and inner sheath, be filled with packing layer, inner sheath is wrapped with metal screen layer, and metal screen layer is wrapped with oversheath, is provided with reinforcement steel wire in oversheath.
Described inner sheath and oversheath all adopt flame retardant polyolefine material.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is strengthened the structure of steel wire by arranging in the oversheath of ribbon heater, greatly strengthens ribbon heater intensity, and has optimized and be subject to force parameter, is erected at the medium-term and long-term use in high-altitude and also can not ruptures, and has ensured device security, has reduced business economic loss.
Brief description of the drawings:
Accompanying drawing 1 is the utility model structural representation.
Embodiment:
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail:
In a kind of oversheath, be provided with the flat ribbon heater of strengthening steel wire, comprise conductor wire core: the three piece copper cash of conductor wire core 1 for being arranged in parallel, every copper cash is all enclosed with the first insulating barrier 2 and the second insulating barrier 3 outward, conductor wire core 1 is wrapped with inner sheath 5, between conductor wire core 1 and inner sheath 5, be filled with packing layer 4, inner sheath 5 is wrapped with metal screen layer 6, and metal screen layer is wrapped with oversheath, is provided with and strengthens steel wire 7 in oversheath; Inner sheath 5 and oversheath all adopt flame retardant polyolefine material.
Above-described embodiment is only preferably execution mode of the present utility model, and in addition, the utility model can also have other implementations.It should be noted that, do not departing under the prerequisite of the utility model design, within any apparent improvement and modification all should fall into protection range of the present utility model.
