Abstract
The utility model relates to the technical field of cables. The utility model provides a water-proof cable. The purpose of the utility model is to provide a moisture-proof and water-proof cable with good shielding property and good high temperature resisting property. The cable includes single-strand cable parts. Each single-strand cable includes at least three conductors (1). The conductors are all wrapped with insulating layers (2). At least two single-strand cables are wrapped with inner shielding layers (3) to form a single-strand shielding cable body. Filling material (4) is filled in a gap between the inner shielding layers (3) and the single-strand cables. At least two single-strand shielding cables are wrapped with outer shielding layer (5). The outer shielding layer is wrapped with water-proof layer (6). The water-proof layer (6) is wrapped with sheathing layers (7). The inner shielding layers are copper layer. Through holes are disposed on all copper layer. The outer shielding layer includes copper foils. The two sides of the copper foils are provided with aluminium foils. The water-proof layer (6) includes non-woven fabrics. The two sides of the non-woven fabrics are all disposed with polyacrylate layers.
Description
Technical field
The utility model relates to cable technology field, and a kind of water repellent electric cable is provided.
Background technology
Cable, when light rail, subway or indoor laying, has proposed very high request to its waterproof, protection against the tide, fire-retardant, fire resistance.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.
From 1836, produce in the world article one lv power cable (the wrapped copper conductor of rubber belt) 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 the state-owned and above enterprise of scale of China's wires and cables industry is approximately 5000, and 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 each main industry requirement to electric wire performance of national economy, 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, waterproof, protection against the tide, a kind of water repellent electric cable that heat-resisting ability is good.
The present invention is to achieve these goals by the following technical solutions:
