Abstract
The utility model relates to a coal-mine radiation-type leakage coaxial cable and relates to the technical field of cables. The coal-mine radiation-type leakage coaxial cable is characterized by comprising an inner conductor, an insulator arranged outside the inner conductor, an outer conductor arranged outside the insulator and a sheath arranged on the outer conductor. The coal-mine radiation-type leakage coaxial cable has better bending flexibility, has longer service life compared with a common cable, has wider application temperature range, and has higher use frequency, lower frequency attenuation, good overall shielding performance and high reliability.
Description
Technical field
The utility model relates to the cable technology field, is specifically related to a kind of colliery and uses radial leak coaxial cable.
Background technology
Wires and cables industry is the second largest industry that China is only second to automobile industry, and product variety satisfies rate and domestic market occupation rate all above 90%.Worldwide, the Chinese electric wire gross output value has surpassed the U.S., becomes first in the world electric wire producing country.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.China's economic growth continuously and healthily; For cable products provides the huge market space, the temptation that Chinese market is strong makes the world all focus on Chinese market to sight; Reforming and opening up to the outside world short decades, the formed huge production capacity of Chinese cable manufacturing industry lets the world regard with special esteem.Along with the continuous expansion of industry sizes such as China Power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire already also has huge development potentiality.
Coaxial cable (Coaxial) has been meant two concentric conductors, and the cable in conductor and the shared same axle center of screen.The copper conductors that modal coaxial cable is isolated by insulating material is formed, and is another layer ring shaped conductor and insulator thereof in the outside of nexine insulating material, and whole then cable is encased by the sheath of polyvinyl chloride or special teflon material.The occasion that use with signal-transmitting cable in the colliery is more abominable, and than common cable, the requirement of strength of this type cable is very high, needs corrosion-resistant, rub resistance, acid-fast alkali-proof performance all very strong, also needs stronger stretch-proof performance.Owing to accident occurs through regular meeting in the colliery, cause the cable can't transmission signals.At this moment need develop some subsequent use performances of cable.
The utility model content
The utility model technical problem to be solved is to provide a kind of reasonable in design, and radial leak coaxial cable is used in the colliery of economy and durability.
The utility model technical problem to be solved adopts following technical scheme to realize,
Radial leak coaxial cable is used in a kind of colliery, it is characterized in that: comprise inner wire, be located at the outer insulator of inner wire, be located at the outer outer conductor of insulator and be located at the sheath on the outer conductor.
Described outer conductor is provided with slotted eye.
Described insulator is a foamed polyethylene.
Described outer conductor is braiding or bundle strand outer conductor.
Described sheath is fire-retardant adjudicate two cases together ethene sheath.
The beneficial effect of the utility model is: the utlity model has crooked preferably softness, than common cable long service life, the serviceability temperature scope is wideer, frequency of utilization is higher, decay is lower, the bulk shielding performance is good, reliability is high.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, radial leak coaxial cable is used in a kind of colliery, comprises inner wire 5, is located at the outer insulator 4 of inner wire 5, is located at the outer outer conductor 2 of insulator 4 and is located at the sheath 1 on the outer conductor 2.Outer conductor 2 is provided with slotted eye 3, and insulator 4 is a foamed polyethylene, and outer conductor 2 is braiding or bundle strand outer conductor, and sheath 1 is fire-retardant adjudicate two cases together ethene sheath.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
