Abstract
The invention discloses a high-temperature resistant fireproof cable. The high-temperature resistant fireproof cable comprises main wire cores, a copper strip belting layer, a shielding layer, an insulating layer, an armor layer, a waterproof layer and a protective sleeve; the center of the copper strip belting layer is provided with a reinforcing piece, the cross section of the reinforcing piece is composed of a square and a circle arranged in the center of the square, the outer side of the insulating layer is wrapped with an aluminium silicate aluminium silicate layer, and an outer shielding layer is arranged between the armor layer and the waterproof layer. The cable is good in electrical conductivity, the service life is long, the cable is resistant to high temperature, oil and corrosion, fireproof, and mainly applied to the fields such as computers, the communication, the power generation, chemical engineering and petroleum, the cable is waterproof and antioxidative, the shielding performance is strong, and the cable quality is improved.
Description
Technical field
The invention belongs to field of cables, particularly relate to a kind of fire resistant 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, environmental protection and energy saving, the requirement of the aspects such as the utilance of distribute heat is high all especially.Such as present general cable adopts single screen usually, and shield effectiveness is inadequate.And for example present cable, once burning will give out a large amount of dense smoke, pernicious gas, causes great harm.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, the excellent and waterproof oil resistant of shielding insulation performance, the fire resistant cable of environmental protection and energy saving.
The present invention takes following technical scheme to realize: a kind of fire resistant cable; it comprises master core, copper strips belting layer, screen, insulating barrier, armour, watertight composition and protective sleeve; described copper strips belting layer center is provided with reinforcement; described reinforcement cross section is made up of a square and one, center circle thereof; wrap up alumina silicate thermal insulation layer outside described insulating barrier, between described armour and described watertight composition, be provided with outer shielding layer.
Further, described screen is woven by Stainless Steel steel wire outsourcing tinfoil paper to form.
Further, by macromolecule water uptake cotton crosslinked third, solidifying to form described master core be by tinned copper wire outsourcing annealed wire to described watertight composition, according to the ratio of 20/0.5 square millimeter stranded braiding to the right.
Further, described reinforcement is the center woven by multiply annealing nickel coated steel wire, and coated with fluoroplastic forms, and four limits of described reinforcement are tangent with described master core circumference respectively.
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 be mainly used in the fields such as computer, communication, generating, chemical petroleum, waterproof is anti-oxidant, shielding properties is strong, improves cable quality.
