Abstract
The utility model provides an ultrahigh temperature shielding control cable which adopts the structure that a conductor wraps an insulating layer, and then a brass wire shielding layer and an inner protection layer are wound or wrapped to form a single-core shielding wire. A plurality of single core shielding wires are intertwisted to form a cable core according to the arrangement of a concentric circle, and a protection layer, an inner sheath, a total shielding layer, a refractory layer, an insulating fireproof layer and a refractory layer sequentially wind or wrap outside the cable core, and finally an outer sheath wraps outsides the cable core. The utility model adopts the technical proposals that the conductor wraps the insulating layer, then the brass wire shielding layer and the inner protection layer are winded or wrapped to form the single core shielding wire, a plurality of single core shielding wires are intertwisted to form the cable core according to the arrangement of the concentric circle, and multiple layers such as the protection layer, the inner sheath, the total shielding layer, the refractory layer, the insulating fireproof layer, the refractory layer, the outer sheath, and the like sequentially wind or wrap outside the cable core, thereby the problem that the prior cable cannot satisfy the multi-function requirements such as high-temperature impact resistance, fire resistance, cold resistance, wear resistance, and the like in a special environment and using place is solved. The utility model is suitable for the ultrahigh temperature shielding control cable used for a field having complex and bad using environment, and in particular to the ultrahigh temperature shielding control cable used for an instantaneous high-temperature environment.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to the shielding conductor be made up of conductor outer wrapping insulating barrier, screen and sheath and cable core and the superhigh temperature shielding control cable of wrapped more cold-resistant multilayer protection such as fire-resistant outside cable core.
Background technology
The existing electrical equipment that is used for some special control appliance connects and shields control cable with superhigh temperature, at first can be abominable because of environment such as fields of employment, have high temperature resistant impact, fire-resistant, cold-resistant, wear-resisting etc. more multi-functional when requiring cable work; Secondly, cable can satisfy instructions for use at aspects such as flexibility, insulating properties.But the weak point that in use exists of this type of cable product is at present: one, product is produced by a plurality of supporting enterprises, and transportation range is far away, and intermediate link is many, makes the production cycle lengthening, product subject to damage in transportation simultaneously, difficult quality guarantee; Two, the existing cable that uses adopts manual coiling multi-layer high-temperature band on the heat-insulating, fire-preventing layer, and this high temperate zone costs an arm and a leg, and causes product cost to improve, and makes by hand because of employing again, and operation is many, the time is long, and the production cycle is increased; Three, the existing cable that uses, its single-core shielding line adopts the copper wire braid, constitute the cross network structure, single core shielding external diameter increases, the entire outer diameter of cable is strengthened, and flexibility is poor, again because of the influence of copper wire joint, under the twisting force of follow-up stranding operation strand system, easily cause damage, influence product quality insulating; Four, the existing cable that uses, its heat-insulating, fire-preventing layer is the wrapped structure that adopts manual coiling multi-layer high-temperature band, it or not entity closely, gapped between band and the band, Duplication and surface quality can be affected when manual coiling, and can cause coming off easily under the effect of high temperature and high speed gas-flow and have a strong impact on the heat-insulating, fire-preventing effect.
Summary of the invention
At above-mentioned situation, the purpose of this utility model is to provide a kind of superhigh temperature shielding control cable, and it had both had high temperature resistant preferably impact, fire-resistant, cold-resistant, wear-resisting etc. more multi-functional; Flexibility, insulating properties are preferably arranged again; And work simplification, the production cycle shortens, manufacturing cost reduction, steady quality, safe and reliable, heat-insulating, fire-preventing is effective, can bear TRANSIENT HIGH TEMPERATURE and impact.
To achieve these goals; a kind of superhigh temperature shielding control cable; the conductor wrap insulate layer that it is formed by stranded copper wire strand system, and outer wrapped copper wire screen of insulating barrier and outsourcing tack plastic film sheath composition single-core shielding line, several single-core shielding lines are arranged by donut and are twisted into cable core; the wrapped successively outward protective layer of cable core; parcel inner sheath, total screen, wrapped flame retardant coating, parcel heat-insulating, fire-preventing layer; wrapped flame retardant coating wraps up oversheath at last.
For implementation structure optimization, its further step is:
Single-core shielding line is more than three and three.
Inner sheath is the cold resistance polyvinyl chloride layer.
Total screen is the tinned copper wire layer.
The heat-insulating, fire-preventing layer is the polymeric layer that contains metal hydrate.
Oversheath is the flame-proof polyvinyl chloride layer.
Protective layer comprises wrapped one deck mica tape and one deck glass tape, wrapped again two layers of F4 film.
Flame retardant coating comprises wrapped one deck mica tape and one deck glass tape.
Flame retardant coating comprises wrapped one deck mica tape and one deck high flame retardant glass tape.
The utility model adopts the conductor wrap insulate layer of being made by the stranded copper wire strand; wrapped again or parcel screen and sheath are formed single-core shielding line; several single-core shielding lines are arranged by donut and are twisted into cable core; the wrapped successively outward or parcel protection of cable core; in protect; total shielding; fire-resistant; heat-insulating, fire-preventing; the technical scheme of multilayer such as fire-resistant and protect has outward solved existing superhigh temperature shielding control cable and can not satisfy high temperature resistant impact in particular surroundings and field of employment; fire-resistant; cold-resistant; multi-functional requirement such as wear-resisting and to flexibility; insulating properties has the problem of special instructions for use.
The beneficial effect that the utility model is produced compared to existing technology:
(a) adopt conductor outer wrapping or wrapped thinwalled insulation layer and copper wire screen to form single-core shielding line, make that the total body diameter of cable reduces, softness improves, install lay simple and easy, convenient;
(b) multiple layer refractory, fire prevention and protection make the heat-insulating, fire-preventing better effects if, can bear TRANSIENT HIGH TEMPERATURE and impact;
(c) work simplification, with short production cycle, low cost of manufacture, steady quality, safe and reliable.
The utility model is fit to the environment for use complexity, occasion such as abominable shields control cable with superhigh temperature, is particularly suitable for shielding control cable with superhigh temperature in high temperature and high speed gas-flow and the TRANSIENT HIGH TEMPERATURE environment.
Below in conjunction with drawings and Examples the utility model is described in further detail.
