Abstract
The utility model discloses a high-temperature-resistant corrosion-resistant computer cable, comprising four conductor groups, each of which is formed by intertwisting of two conductors wrapped by insulating layers and a tensile core. Each of the four conductor groups is externally wrapped by an inner wrapping layer formed by lapping of an insulating wrapping tape, a sub shielding layer and a middle wrapping layer in order. The four conductor groups wrapped by the middle wrapping layers are intertwisted to form a cable core, which is externally wrapped by an outer wrapping layer and a main shielding layer. A filling layer, which is composed of fillers, is arranged among the cable core center, the cable core and the outer wrapping layer. Five tensile steel wires are disposed in the filling layer, wherein one of the five tensile steel wires are located at the cable core center, and the other four are located between the middle wrapping layers and the outer wrapping layer. The external of the main shielding layer is wrapped by a sheath layer. The high-temperature-resistant corrosion-resistant computer cable of the utility model is reasonable in structural design. The inner, middle and outer wrapping layers are adopted to enhance the insulating performance and the fireproof performance of the cable. The match between the five tensile steel wires and the tensile cores increases the tensile strength of the cable and prolongs the service lifetime of the cable.
Description
Technical field
The utility model relates to the computer cable field, relates in particular to a kind of high-temperature resistant anti-corrosive computer cable.
Background technology
The utility model is applicable to that industries such as exchanging 300/500V electric power, metallurgy, petrochemical industry have high-low temperature resistant, corrosion-resistant and be main automatic control with the electronic computer to specific (special) requirements occasions such as the soda acids of draining the oil, is particularly useful for computer distributed control system, automation control system makes control line and instrument and meter is used in detection.
The essential structure of cable be insulated wire cores with two be twisted into to or three in groups stranded, the shielding form can be to a minute shielding, total shielding, divide shielding form such as shielding totalling shielding, around after add sheath etc.But the resistance to elevated temperatures of previous cable and tensile strength etc. do not reach the requirement in the practical work process far away.
The utility model content
In order to remedy the deficiency of prior art, the purpose of the utility model provides a kind of high-temperature resistant anti-corrosive computer cable, and reasonable in design has improved the insulation property and the tension of cable and thought ability, has satisfied the demand in the practical work process.
The technical scheme of the utility model is following:
The high-temperature resistant anti-corrosive computer cable; Comprise four conductor groups; It is characterized in that: described four conductor groups are respectively by the conductor of two wrap insulate layers and tensile core is stranded each other constitutes, and described four conductor groups are enclosed with interior lapping layer, sub-shield, the middle lapping layer of the wrapped formation of insulation band, four of lapping layer mutual stranded formation cable cores of conductor group in the parcel outward respectively successively; Cable core is wrapped with outer belting layer, total screen; Be provided with the packed layer that filler constitutes between cable core center and cable core and the outer belting layer, be provided with five tension steel wires in the packed layer, one of them is positioned at the cable core center five tension steel wires; All the other four are located at respectively between middle belting layer and the outer belting layer, and described total screen outside is enclosed with restrictive coating.
