Abstract
The invention discloses a high-temperature-resistant double-shielded cable. The high-temperature-resistant double-shielded cable comprises a main cable core, control cable cores as well as a copper belt wrapped layer, a tinned copper wire woven shielding layer, a fluororubber insulating layer and an outer protective sleeve which are packaged on the outer surface in sequence, wherein the three control cable cores are stacked up and down and are mutually externally tangent and tightly arranged; a reinforced shielding layer, an aluminum silicate heat insulating layer and an inner protective sleeve layer are arranged between the fluororubber insulating layer and the outer protective sleeve in sequence. The cable is good in conductivity, high-temperature-resistant, fireproof, oil-resistant, corrosion-resistant, waterproof, anti-oxidant, strong in shielding performance and high in heat utilization rate; meanwhile, fluorescent light can be emitted in a dark environment, so that the cable is conveniently laid and maintained in a dark place.
Description
Technical field
The invention belongs to field of cables, particularly relate to a kind of high temperature resistant screened cable.
Background technology
At present, along with socioeconomic development, cable consumption increases rapidly, also constantly improves the quality requirement of cable.The cable used in the fields such as computer, communication, generating, chemical petroleum, to the fire resistant of cable, shielding insulation performance, waterproof oil resistant, the requirement of the aspects such as the utilance of distribute heat is high all especially.But present general cable runs into the situations such as installation, maintenance in the environment at night or dark, needs the position by the accurate positioning cable of external light source ability, installs once cable, overhauls and just may cause great potential safety hazard not in time.
Only meet the requirements, fail safe during production and application in these fields could be improved.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of fire resistant strong, shielding insulation performance is excellent, waterproof oil resistant, and shielding is strong and can send fluorescence, the high temperature resistant screened cable of the advantages such as utilization is laid, maintenance.
The present invention takes following technical scheme to realize: a kind of high temperature resistant screened cable, it comprises master core, control conductor and is wrapped in copper strips belting layer, tinned copper wire woven shield, fluorubber insulating barrier, the oversheath of outside successively, described master core, described control conductor are three, overlapping, mutual circumscribed tight arrangement up and down, described master core is by tinned copper wire outsourcing annealed wire, overlapping up and down, according to 20/0.5 square millimeter ratio stranded braiding to the right; A ground connection core is also wrapped up in described copper strips belting layer inside, is provided with successively and strengthens screen, alumina silicate thermal insulation layer, inner restrictive coating between described fluorubber insulating barrier and described oversheath.
Further, described control conductor is made up of the zinc-plated aluminium wire cable core that coppered wire is stranded outward and the nickel coated steel wire armour be wrapped in outside cable core.
Further, described reinforcement screen is woven by the outer aluminium foil of the zinc-plated ultra-fine soft copper silk of multiply high strength 99.9999% anaerobic annealing and forms.
The present invention has following beneficial effect in sum: good conductivity of the present invention, long service life, fire resistant, oil resistance anticorrosion loses, and is mainly used in the fields such as computer, communication, generating, chemical petroleum, waterproof is anti-oxidant, shielding properties is strong, and meanwhile, cable can also send fluorescence in the environment of darkness, be conducive to the orientation of identification cable, be convenient to laying and maintenance at shady place of cable.
