Abstract
The utility model discloses an insect bite-prevention serial-type ribbon heater, 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 inner sheath is coated with a metal shielding layer; the metal shielding layer is coated with an outer sheath; the outer sheath is coated with an insect-prevention protective layer; both the inner sheath and the outer sheath are made of flame-retardant polyolefin; and a plurality of nylon wires are tightly wound and braided to form the insect-prevention protective layer. As the insect-prevention protective layer is added at the outer layer of the serial-type ribbon heater, damage to the ribbon heater due to insect bite can be effectively prevented, 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 the series electric heating band that a kind of ant prevention bites.
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 in southern certain areas, worm ant is more and can gnaw and bite ribbon heater, causes device damage, equipment heating properties can not get ensureing, to enterprise, brings 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 the series electric heating band that a kind of ant prevention bites, solution is in southern certain areas, and worm ant is more and can gnaw and bite ribbon heater, causes device damage, equipment heating properties can not get ensureing, brings the problem of direct economic loss to enterprise.
The technical solution adopted in the utility model is:
The series electric heating band that a kind of ant prevention bites; comprise conductor wire core: 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, be filled with packing layer; inner sheath is wrapped with metal screen layer, and metal screen layer is wrapped with oversheath, and oversheath is wrapped with ant prevention protective layer.
Described inner sheath and oversheath all adopt flame retardant polyolefine material.
Described ant prevention protective layer be some nylon yarns be closely wound around braiding form.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is by adding the structure of ant prevention protective layer at series electric heating band skin, effectively prevent from that worm ant from gnawing to bite the ribbon heater of causing and damage, and ensured device security, 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:
The series electric heating band that a kind of ant prevention bites, 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, inner sheath 5 is wrapped with metal screen layer 6, and metal screen layer 6 is wrapped with oversheath 7, and oversheath 7 is wrapped with ant prevention protective layer 8; Inner sheath 5 and oversheath 7 all adopt flame retardant polyolefine material; Ant prevention protective layer 8 forms for some nylon yarns are closely wound around braiding.
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.
