Abstract
The utility model discloses a serial-type ribbon heater with a metal reinforcement rib, which comprises a conductive wire core. The conductive wire core is three copper wires arranged triangularly; each copper wire is coated with a first insulating layer and a second insulating layer; the conductive wire core is coated with an inner sheath; a material filling layer is filled between the conductive wire core and the inner sheath; the metal reinforcement rib is arranged inside the material filling layer; the inner sheath is coated with a metal shielding layer; the metal shielding layer is coated with an outer sheath; and both the inner sheath and the outer sheath are made of flame-retardant polyolefin. Through arranging the metal reinforcement rib in the material filling layer of the serial-type ribbon heater, strength of the ribbon heater is greatly enhanced, stress parameters are optimized, the ribbon heater does not break when set up high in the air and used for a long time, security of the equipment is ensured, and the economic loss of an enterprise is reduced.
Description
technical field:
The utility model relates to field, ribbon heater, relates in particular to a kind of series electric heating band with metal reinforcing.
background technology:
Serial heating band is by three, to have same cross-sectional to amass, the parallel insulation copper stranded conductor of certain length is as power source bus and heating heart yearn, by the reliable short circuit in its one end, the other end connects the voltage of 380V(or design) power supply, just formed a star load, according to joule-Lenz's law: Q=0.24IRT, electric energy conversion is that heat energy star load is constantly emitted heat, forms that one continuous, uniform electric-heating belt generates heat.Because it is safe and reliable, purposes is wide, free from environmental pollution, the life-span is long, be widely used in the pipelines of industrial enterprise such as oil, chemical industry, iron and steel, electric power, the tracing thermal-insulating of storage tank, anti-freezing, antifreeze; Generally be applicable to general area, hazardous area and corrosion region.But it is aerial serial heating band 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, to enterprise, bring direct economic loss.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 a kind of series electric heating band with metal reinforcing, solution need to be arranged on serial heating band high aerial in some occasion, because the reason time of deadweight has been grown the easily sagging fracture of appearance of ribbon heater, to enterprise, bring the problem of direct economic loss.
The technical solution adopted in the utility model is:
A kind of series electric heating band with metal reinforcing, comprise conductor wire core, it is characterized in that: conductor wire core is to be three copper cash that isosceles triangle is arranged, 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, is filled with packing layer, is provided with metal reinforcing in packing layer, inner sheath is wrapped with metal screen layer, and metal screen layer is wrapped with oversheath.
Compared with prior art, the beneficial effects of the utility model are:
The utility model, by the structure of metal reinforcing is set in series electric heating band packing layer, strengthens ribbon heater intensity greatly, 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 rupture, and has ensured device security, has reduced business economic loss.
accompanying drawing explanation:
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:
A kind of series electric heating band with metal reinforcing, comprise conductor wire core: three copper cash that conductor wire core 1 is arranged for being isosceles triangle, 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, in packing layer 4, be provided with metal reinforcing 8, inner sheath 5 is wrapped with metal screen layer 6, and metal screen layer 6 is wrapped with oversheath 7; Inner sheath 5 and oversheath 7 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.
