Abstract
The utility model discloses a kind of rodent-resistant cable, belong to optical cable technology field, solving mouse in prior art will destroy oversheath, just can play the problem of the effect of repellent mouse.The utility model comprises optical fiber, is set in the oversheath outside optical fiber, the reinforcement arranged between optical fiber and oversheath, and oversheath is black flame-retardant oversheath, and oversheath is provided with multiple aperture, is filled with rat destruction material in aperture.The utility model is used for preventing mouse to sting bad optical cable.
Description
Technical field
A kind of rodent-resistant cable, for preventing mouse to sting bad optical cable, belongs to optical cable technology field.
Background technology
(letter out thread 22 years) March in 1897, China's first underground power cable knocks down use in Shanghai, and the light conduits of the most edge sheath sheath of those the 2700 meters of long rubbers used then is imported product.Until after 42 years (nineteen thirty-nine) just produce the domestic cable of root of informing against in Kunming (cable factory).Before 1949, wires and cables industry only has worker more than 2000 people, production equipment about 500, year the highest copper consumption only 6500 tons.Wherein Kunming, Shanghai, Tianjin, four, Shenyang Electric Wire Factory share copper 5700 tons, and output accounts for 87.7% of the whole nation, wires and cables industry slower development.Until after New China was founded in l949, the wires and cables industry of China just obtains develop rapidly.
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.
Traditional cable and optical fiber mostly are split, optoelectronic composite cable structure is less, photoelectricity composite demand softness, tension, oil resistant, high temperature resistant, low temperature resistant, rub resistance etc., high to the environmental performance demand of cable, screen layer many employings tinsel establishment of used for oil platform common cable in the past, easily there is exoperidium bulge or pricks the problem of threading core in cable shield.
Have expelling mouse agent to be arranged between oversheath and internal layer with layer assembling structure in prior art, mouse will destroy oversheath, just can play the effect of repellent mouse, cable finally still can be caused to mend and destroy.
Summary of the invention
The utility model provides a kind of rodent-resistant cable for the deficiencies in the prior art part, and solving mouse in prior art will destroy oversheath, just can play the problem of the effect of repellent mouse.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of rodent-resistant cable, comprise optical fiber, be set in the oversheath outside optical fiber, the reinforcement arranged between optical fiber and oversheath, is characterized in that: oversheath is black flame-retardant oversheath, and oversheath is provided with multiple aperture, is filled with rat destruction material in aperture.
Further, described rat destruction material is polyolefin SR-8851 or expelling mouse agent.
Further, described oversheath is provided with hanging ring.
Further, described hanging ring is the clamping button of annular.
Further, water barrier and flame-retardant layer is provided with between described reinforcement and oversheath.
Further, described water barrier comprises enhancement Layer bonding successively, basic unit, water blocking layer and overlayer, and described enhancement Layer is copper mesh, and basic unit and overlayer are nonwoven fabrics, and water blocking layer is mica tape or glass fibre.
Further, described flame-retardant layer is comprise the copper mesh, expanded granular layer, the mica layer that set gradually.
Further, described optical cable is butterfly optical cable.
Compared with prior art, the utility model has the advantage of:
One, by arranging aperture on oversheath, to mix expelling mouse agent in oversheath inner clip, mouse would not be close, thus play the effect of complete protection against rodents, and oversheath also would not be destroyed;
Two, hanging ring can facilitate attached cable, and hanging ring be annular clamping button, conveniently hang and get from;
Three, in oversheath, be provided with water barrier and flame-retardant layer, waterproof and fire-retardant effect can be played.
