Abstract
The utility model relates to the technical field of cables. A fire-proof water-proof cable includes at least three conductors (1). The conductors are wrapped with insulating layers (2). The conductors wrapped with the insulating layers (2) are wrapped with inner shielding layers (3). The gaps between the inner shielding layers (3) and the insulating layers (2) are filled with filling material (4). The inner shielding layers (3) are wrapped with outer shielding layer (5). The outer shielding layer (5) is wrapped with water-proof layer (6). The water-proof layer (6) is wrapped with sheath layers (7). The inner shielding layers and the outer shielding layers all include copper foils. The two sides of the copper foils are equipped with aluminum foils.
Description
Technical field
The utility model relates to cable technology field, and a kind of fire-resistant water repellent electric cable is provided.
Background technology
Cable is in the time of light rail, subway or indoor laying, and, fire resistance fire-retardant to it proposed very high request.In order to meet the requirement of cable environment for use, according to different fire-retardant, the fire-resistant deisgn product structures that requires.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, the one, composite sheath structure, the 2nd, aluminium sheath structure.Its anti-shielding ability, a little less than water-and fire-proof ability.
Produced in the world Article 1 lv power cable (the wrapped copper conductor of rubber belt) 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, has also been obtained larger progress.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.At present approximately 5000 of the state-owned and above enterprises of scale of China's wires and cables industry, wherein large enterprise has 19, and the gross output value accounts for 11% of whole market share.
Electric wire is to carry the 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 the requirement of the each main industry of national economy to electric wire performance, and national economy thinks that most industries are 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 fire-resistant water repellent electric cable of one that heat-resisting ability is good.
The present invention is to achieve these goals by the following technical solutions:
A kind of fire-resistant water repellent electric cable, it is characterized in that: comprise at least 3 conductors 1, the outer all wrap insulate layers 2 of conductor, all conductors 1 that are enclosed with insulating barrier 2 are wrapped up by internal shield 3, and filler 4, internal shield 3 outer wrapping outer shielding layers 5 are filled in the gap between internal shield 3 and insulating barrier 2, outer shielding layer 5 outer wrapping water blocking layers 6, water blocking layer 6 outer wrapping restrictive coatings 7, described internal shield and outer shielding layer include Copper Foil, and Copper Foil two sides is equipped with aluminium foil.
Described filling filler 4 is fireproof water-resisting tape, and it comprises mica layer, and mica layer two sides is the strengthening course of adhering glass fiber mesh establishment respectively, and the film that bonding one deck is made up of water-proofing powder on strengthening course forms water blocking layer.
Described filling filler 4 is glass fibre.
Described filling filler 4 is rubber.
Described water blocking layer 6 comprises bonding successively reinforced layer, basic unit, water blocking layer and cover layer, and described reinforced layer is copper mesh, and basic unit and cover layer are nonwoven fabrics, and water blocking layer is mica tape or glass fibre.
Because the utility model 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.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model.
