Abstract

The utility model discloses a high temperature resistance detection instrument cable for an intrinsically safe system, which comprises four twisted-pair conductor groups; the four twisted-pair conductor groups are arranged in a square shape; the four twisted-pair conductor groups are respectively formed by stranding two cable conductors coated with insulating layers; each pair of stranded cable conductors are coated with a separated shielding layer; a wrapping tape layer, a shielding layer, an inner jacket, an armor layer and an outer sheath layer are sequentially coated outside the four twisted-pair conductor groups from inside to outside; drainage threads are uniformly distributed inside the separated shielding layers of the twisted-pair conductor groups; the drainage thread of each twisted-pair conductor group is positioned at the position closest to one cable conductor of the adjacent twisted-pair conductor group; and a drainage thread is arranged between the wrapping tape layer and the shielding layer of each twisted-pair conductor group. The high temperature resistance detection instrument cable has simple structure and is convenient and rapid to manufacture; the flame retardance and the waterproofness of the high temperature resistance detection instrument cable are greatly improved; the drainage thread of each twisted-pair conductor group is positioned at the position closest to one cable conductor of the adjacent twisted-pair conductor group and the separated shielding layers are added, so that the anti-interference performance is greatly improved and the high temperature resistance detection instrument cable is suitable for places with dense population.

Description

Intrinsic safety system is with high temperature resistant detecting instrument cable
Technical field
The utility model relates generally to field of cables, relates in particular to a kind of intrinsic safety system with high temperature resistant detecting instrument 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.
The application of electronic computer, instrument and meter is universal day by day, and people's awareness of safety constantly strengthens, and the performance and the environmental requirement of the cable supporting with it also improved constantly.Existing computer and instrument are high temperature resistant not high with fire resistance with cable, and the security reliability of cable is low under fire condition, and shielding properties and interference free performance are not high, are not suitable for as densely populated and higher to device security reliability requirement place.
Therefore, it is good to be badly in need of a kind of high temperature resistant, anti-flammability, shielding, anti-interference, and safe intrinsic safety system is with high temperature resistant detecting instrument cable.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, to provide a kind of intrinsic safety system with high temperature resistant detecting instrument cable.
The utility model is realized through following technical scheme:
Intrinsic safety system is with high temperature resistant detecting instrument cable; Comprise four pair twist conductor groups; Described four pair twist conductors are formed square arrangement; It is characterized in that: described four pair twist conductor groups are enclosed with all by the outside respectively that two cable conductors of insulating barrier are stranded to be constituted; Two cable conductor outsides after stranded are enclosed with individually shielded layer, and four pair twist conductor group outsides are enclosed with belting layer, screen, sheath, armour, external sheath layer from inside to outside successively, and the inboard of the individually shielded layer of described pair twist conductor group is evenly equipped with drainage thread; The drainage thread of each pair twist conductor group is positioned at apart from wherein position that cable conductor is nearest of adjacent pair twist conductor group, also is provided with a drainage thread between described belting layer and the screen.
Described individually shielded layer is a semiconductive shielding layer.
The direction of lay that is two cable conductors in two conductor groups that diagonal arranges in described four conductor groups is identical, and the direction of lay of two cable conductors in four conductor groups in adjacent two conductor groups is vertical each other.
Described screen adopts aluminium-plastic tape overlapping wrapped.
Described armour adopts the steel band braiding to coat.
Described cable conductor adopts bare copper wire.
The utility model has the advantages that:
The utility model is simple in structure, manufacturing is convenient; Its resistance to wear, anti-flammability, water proofing property improve greatly; The drainage thread of each pair twist conductor group is positioned at apart from wherein position that cable conductor is nearest of adjacent pair twist conductor group; And increased the individually shielded layer of one deck, and improved anti-interference greatly, be adapted at densely populated place and use.
