Description
Technical field
The present invention relates to field of cable technology, provide a kind of Anti-moth-eating cable of double shield.
Background technology
The problems such as existing cable in use exists mouse and stings, termite moth, and waterproof and dampproof ability is not good.
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 in a kind of screening energy strong, moisture protection is strong, the Anti-moth-eating cable of a kind of double shield that Anti-moth-eating ability is good.
The present invention is by the following technical solutions to achieve these goals:
A kind of Anti-moth-eating cable of double shield, it is characterized in that: comprise conductor 1, be wrapped in the insulating barrier 2 outside conductor 1, insulating barrier 2 is outside equipped with internal shield 4, internal shield 4 is wrapped with inner restrictive coating 5, inner restrictive coating 5 is wrapped with reinforced layer 6, reinforced layer 6 is wrapped with outer shielding layer 7, outer shielding layer 7 is wrapped with external sheath layer 8, uniformly in described external sheath layer 8 be provided with cavity 9, be provided with pest repellant in cavity 9, be provided with optical fiber 11 in described inner restrictive coating 5, optical fiber 11 is wrapped with watertight composition 10.
In technique scheme, described in described screen 4, internal shield 4 adopts layers of copper, and described layers of copper is evenly equipped with through hole.
In technique scheme, described outer shielding layer 7 comprises Copper Foil, and Copper Foil two sides is provided with aluminium foil.
In technique scheme, described watertight composition 10 comprises reinforced layer bonding successively, 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.Watertight composition 10 produces deformation by not allowing after water, thus can not extrude optical fiber because watertight composition 10 expands, and causes Optical Fiber Transmission rate to decline.
In technique scheme, space between described insulating barrier 2 and internal shield 4 is provided with inserts 3, described inserts is fireproof water-resisting tape, it comprises mica layer, the strengthening course of mica layer two sides difference adhering glass fiber mesh establishment, the film that bonding one deck is made up of water-proofing powder on strengthening course forms water blocking layer.
Because present invention employs above technology which is put, so possess in screening energy strong, moisture protection is strong, Anti-moth-eating ability.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention.
