The waterproof moisture-proof fire-resistant cable comprises a conductor (1); the conductor (1) is covered with an insulating layer (2); the insulating layer (2) is covered with a nonwoven layer (3); the nonwoven layer is covered with a shield layer (4); the shield layer (4) is covered with an asphalt anticorrosion layer (5); the asphalt anticorrosion layer (5) is covered with a fire-resistant layer (6); the fire-resistant layer (6) is covered with a waterproof layer (7); the waterproof layer (7) is covered with an outer sheath (8); the fire-resistant layer (6) comprises a mica layer and a basalt fiber woven layer; the mica layer is 0.2mm to 0.9mm in thickness. The waterproof moisture-proof fire-resistant cable is applicable to cables.
Description
Technical field
The present invention relates to field of cable technology, provide a kind of waterproof and dampproof fire-resisting cable.
Background technology
Cable is when light rail, subway or indoor are laid, and, fire resistance fire-retardant to it proposes very high request.In order to meet the requirement of cable environment for use, according to different fire-retardant, fire resistant requirements deisgn product structure.Now widely used railway signal cable, railway digital signal cable, cable capable of shielding digital signals in railways, fire resistant railway traffic signal cable, answering machine data transmission cable are divided into two large classes, and one is composite sheath structure, and two is aluminium sheath structures.Its anti-shielding ability, water-and fire-proof ability is weak.
Produced Article 1 lv power cable (the wrapped copper conductor of rubber belt) in the world from 1836 so far, electric wire has developed into a large product category of many uses, various in style.China's wires and cables industry, through the development of more than 70 years, also achieves larger progress.Along with Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.State-owned and the above enterprise of scale about 5000 of current China wires and cables industry, wherein large enterprise has 19, and the gross output value accounts for 11% of whole market share.
Electric wire is the conveying energy, the indispensable basic equipment of transmission of information, and from the today in social informatization, electrified fast development, electric wire has become one of most important basic product in economic construction.Wires and cables industry is again supporting industry, and product must meet each main industry of national economy to the requirement of electric wire performance, and national economy thinks that most industry is all relevant to electric wire, and its industrial status is very important.China's wires and cables industry is still in developing stage at present, and as the important guide's industry of the development of the national economy, the growth of electric wire production and marketing index is generally higher than total value of production in national economy outline.
Summary of the invention
The object of the present invention is to provide a kind of shielding properties strong, the waterproof and dampproof fire-resisting cable of the one that heat-resisting ability is good.
The present invention is by the following technical solutions to achieve these goals:
A kind of waterproof and dampproof fire-resisting cable, it is characterized in that: comprise conductor 1, conductor 1 is wrapped with insulating barrier 2, insulating barrier 2 outer wrapping nonwoven layer 3, nonwoven fabrics water blocking layer outer wrapping screen 4, screen 4 outer wrapping asphalt corrosion resistant layer 5, asphalt corrosion resistant layer outer wrapping flame retardant coating 6, flame retardant coating 6 outer wrapping water blocking layer 7, water blocking layer 7 outer wrapping oversheath 8, described flame retardant coating 6 comprises flame-retardant layer and comprises mica layer and basalt fibre braid, and described mica layer thickness is 0.2-0.9mm.
In technique scheme, described basalt braid, filament diameter is 0.2-0.9mm.
In technique scheme, described water blocking layer 7 comprises reinforced layer bonding successively, basic unit, watertight composition and cover layer, and described reinforced layer is copper mesh, and basic unit and cover layer are nonwoven fabrics, and watertight composition is mica tape or glass fibre.
In technique scheme, screen 4 is layers of copper, and layers of copper is evenly equipped with through hole.
In technique scheme, described screen 4 copper-clad paper tinsel, Copper Foil one or both sides are provided with aluminium foil.
Because the present invention adopts above technical scheme, so possess following beneficial effect:
Make cable obtain higher antistatic interference, the interference of anti-external magnetic field, anti-radio frequency interference ability by inner shield and external shield, water-and fire-proof ability is strong.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention.
