Abstract
The utility model discloses a crosslinked polyethylene insulating control cable which comprises a cable core. The cable core comprises a plurality of cable conductors which are coated by fireproof mica layers; an insulating layer, a taping layer, a shielding layer and a sheath layer are sequentially coated outside the cable conductors which are coated by the fireproof mica layers from inside to outside; the shielding layer is formed through copper tape knitting and has the thickness of 0.3-0.5 mm; a current leading line is laid outside the shielding layer; the taping layer comprises two polyester tape layers; and a steel wire mesh layer is sandwiched between the two polyester tape layers. The crosslinked polyethylene insulating control cable is safe and reliable and is simple in structure, the fire-resisting and flame-resisting properties are realized by the mica layers, the anti-interference and high-temperature-resistant properties are realized by the current leading line, and the fastness is enhanced in a manner that the strengthening steel wire mesh layer is protected through the two polyester tape layers.
Description
Technical field
The utility model relates generally to technical field, relates in particular to a kind of crosslinked polyetylene insulated control 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, be badly in need of a kind of high temperature resistant, anti-flammability, shielding, control cable that anti-interference is good, safe.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, and a kind of anti-flammability, crosslinked polyetylene insulated control cable that anti-interference is good are provided.
The utility model is realized through following technical scheme:
Crosslinked polyetylene insulated control cable; Include cable core; It is characterized in that: described cable core comprises the many cable conductors that are enclosed with fire-resistant mica layer, insulating barrier from inside to outside successively, is enclosed with belting layer, screen, restrictive coating from inside to outside successively after the many cable conductors that are enclosed with fire-resistant mica layer, insulating barrier are stranded, and screen adopts the copper strips braiding to form; Thickness is 0.3-0.5mm; Be laid with drainage thread in the screen, described belting layer includes the two layers polyester belt, accompanies the layer of steel wire net between the two layers polyester belt.
Described insulating barrier adopts crosslinked polyethylene, and thickness is not more than 0.7mm.
Described restrictive coating adopts polyvinyl chloride, and thickness is 1.8-2.0mm, and the thickness of thinnest part is not less than 1.8mm.
Described cable core core number is no less than four-core.
What described cable conductor adopted is bare copper wire.
The utility model has the advantages that:
The utility model is safe and reliable, simple in structure, and mica layer has been realized fire prevention, fire-retardant, and drainage thread has been realized anti-interference, high temperature resistant, protects one deck to reinforce the steel wire of usefulness through the two layers polyester belt, has strengthened the fastness of the utility model.
Description of drawings
Fig. 1 is the structural representation of the utility model.
