Abstract
The utility model discloses a shielded twisted pair cable for an electronic computer. The shielded twisted pair cable comprises three conductor groups, wherein each conductor group is formed by mutually twisting two conductors which are wrapped by insulating layers; a tension resistant core is arranged in each conductor; inner wrapping layers and separated shielding layers wrap the three conductor groups respectively and sequentially; a grounding wire is arranged between each inner wrapping layer and each separated shielding layer; the three conductor groups which are wrapped by the separated shielding layers are twisted with each other to form a cable core; an outer wrapping layer and a general shielding layer wrap the cable core; filling layers consisting of fillers are arranged in the center of the cable core and between the cable core and the outer wrapping layer; tension resistant steel wires are arranged in the filling layers; and a waterproof layer and a sheath layer wrap the general shielding layer. The shielded twisted pair cable is reasonable in structural design; inner and outer wrapping tape layers in different wrapping overlapping ratios are used for improving the fire resistance of the cable, so that strength performance of the integral structure of the cable is effectively improved; the waterproof layer is arranged on the inner side of an outer sheath layer, so that the water resistance is good, and the service life of the cable is prolonged.
Description
Technical field:
The utility model relates to the computer cable field, relates in particular to a kind of electronic computer and uses the pair twist shielded type 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 and water resistance 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 electronic computer and uses the pair twist shielded type cable, and reasonable in design has improved insulation property and the tensile property and the water resistance of cable.
The technical scheme of the utility model is following:
Electronic computer is used the pair twist shielded type cable, comprises three conductor groups, it is characterized in that: described three conductor groups constitute by the conductor of two wrap insulate layers is stranded each other respectively; Be respectively equipped with tensile core in the conductor; Described three conductor groups are enclosed with interior lapping layer, sub-shield outward respectively successively, are provided with earth connection between interior lapping layer and the sub-shield, the mutual stranded formation cable core of three conductor groups of parcel sub-shield; Cable core is wrapped with outer lapping layer, total screen; Be provided with the packed layer that filler constitutes between cable core center and cable core and the outer lapping layer, be provided with four tension steel wires in the packed layer, one of them is positioned at the cable core center three tension steel wires; Its excess-three root is located at respectively between sub-shield and the outer lapping layer; Described total screen outside is enclosed with restrictive coating, and the restrictive coating inwall is provided with watertight composition, and waterproofing layer thickness is not less than 0.10mm.
Described electronic computer is used the pair twist shielded type cable, it is characterized in that: lapping layer, outer lapping layer adopt polyester film or the wrapped formation of aluminium foil in described, and the Duplication of interior lapping layer is not less than 45%, and the Duplication of outer lapping layer is not less than 55%.
Described electronic computer is used the pair twist shielded type cable, it is characterized in that: it is flame-proof polyethylene that described insulating barrier, restrictive coating adopt material.
The utility model has the advantages that:
The reasonable in design of the utility model; Adopt the inside and outside different wrapped Duplication of belting layer to improve the fire resistance of cable; Four tension steel wires match with the conductor that contains tensile core and have strengthened the tensile strength of cable, make that the overall construction intensity performance of cable is promoted effectively, and this external sheath layer inboard is provided with watertight composition; Water resistance is good, has prolonged the useful life of cable.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1:
Electronic computer is used the pair twist shielded type cable, comprises three conductor groups, and three conductor groups constitute by the conductor of two wrap insulate layers 21 is stranded each other respectively; Be respectively equipped with tensile core 3 in the conductor 1; Lapping layer 4, sub-shield 5 were provided with earth connection 6 between interior lapping layer 4 and the sub-shield 5 in three conductor groups were enclosed with respectively outward successively, the mutual stranded formation cable core of three conductor groups of parcel sub-shield 5; Cable core is wrapped with outer lapping layer 7, total screen 8; Be provided with the packed layer 9 that filler constitutes between cable core center and cable core and the outer lapping layer 7, one of them is positioned at the cable core center to be provided with 10, three tension steel wires of four tension steel wires in the packed layer 9; Its excess-three root is located at respectively between sub-shield and the outer lapping layer 7; Total screen 8 outsides are enclosed with restrictive coating 11, and restrictive coating 11 inwalls are provided with watertight composition, and watertight composition 12 thickness are not less than 0.10mm.
Interior lapping layer 4, outer lapping layer 7 adopt polyester film or the wrapped formations of aluminium foil, and the Duplication of interior lapping layer 4 is not less than 45%, and outer wrapped 7 layers Duplication is not less than 55%.
