Abstract

The utility model discloses a corrosion resistance and high-temperature resistance control flexible cable. The flexible cable comprises four inner conductors and a plurality of outer conductors. A fluoroplastic insulating layer is wrapped outside each of the four inner conductors so that four inner insulating cores are formed, and a fluoroplastic insulating layer is also wrapped outside each of the outer conductors so that a plurality of outer insulating cores is formed. After the four inner insulating cores are intertwisted and clustered, an inner taped layer is wrapped outside the four inner insulating cores. After the plurality of outer insulating cores is evenly distributed outside the inner taped layer, a cable core is formed. An outer taped layer, a copper wire woven shielding layer and a fluoroplastic sheath layer are successively wrapped outside the cable core. The outer conductors are evenly arranged outside the inner conductors to form the cable core which is provided with the two taped layers, and the structure design of the two taped layers enables compactness and fireproof performance of the structure of the cable to be improved. Meanwhile, the cable of the utility model exhibits excellent flexibility and is prolonged in terms of the service life.

Description

A kind of anticorrosion high temperature resistant control flexible cable
Technical field:
The utility model relates to control cable, relates in particular to a kind of anticorrosion high temperature resistant control flexible cable.
Background technology:
The soft control cable of using is manufactured the technological process of this type of soft control cable according to GB/T9330-2008 at present: conductor bundle strand-insulating exruded-stranding-extrude sheath, roughly four technologies are crossed and are become to finish.
Adopt the soft control cable bending radius of above-mentioned technology bigger (be not less than the outside diameter of cable 6 times), do not satisfy the installation needs of small space sometimes, bending radius is too small can the damage cable, influences the normal use of product.Because this type of soft control cable flexibility is not fine, frequently move around or crooked occasion shorter useful life, in use the cable conductor frangibility causes cable breakdown or broken string accident.
The structural compactness of this outer cable is relatively poor relatively, and fire resistance does not reach the demand of actual working environment.
The utility model content:
The purpose of this utility model provides a kind of anticorrosion high temperature resistant control flexible cable, and the flexibility of cable, compactedness and fire resistance are superior, are applicable to frequently to move around or crooked occasion long service life.
The technical solution of the utility model is as follows:
Anticorrosion high temperature resistant control flexible cable, comprise four inner wires, several outer conductor, it is characterized in that: described four inner wires, several outer conductor outside are enclosed with the fluoroplastic insulation layer respectively and constitute four interior insulated wire cores, several external insulation core, be surrounded with interior lapping layer outside behind four stranded bunchys of interior insulated wire cores, interior lapping layer constitutes cable core after being evenly distributed with several external insulation cores outward, and cable core is provided with outer lapping layer, copper wire woven shield, fluoroplastics restrictive coating outward successively.
Described anticorrosion high temperature resistant control flexible cable is characterized in that: it is overlapping wrapped that lapping layer adopts the high temperature resistance polyester band in described, and the wrapped rate of putting up is not less than 42%.
Described anticorrosion high temperature resistant control flexible cable is characterized in that: described outer lapping layer adopts the high-temperature fibre band overlapping wrapped, and the wrapped rate of putting up is not less than 52%.
The utility model has the advantages that:
The utility model adopts the outer evenly distribution outer conductor of inner wire to constitute cable core, and cable core has two-layer lapping layer, and the structural design of lapping layer makes construction of cable compactedness, fire resistance get a promotion, and the pliability of cable is superior simultaneously, has prolonged the useful life of cable.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
Anticorrosion high temperature resistant control flexible cable, comprise four inner wires 1, several outer conductor 2, four inner wires 1, several outer conductor 2 outsides are enclosed with fluoroplastic insulation layer 3 respectively and constitute four interior insulated wire cores, several external insulation core, lapping layer 4 in outer being surrounded with behind four stranded bunchys of interior insulated wire cores, improved the structural compactness of cable, constitute cable core after being evenly distributed with several external insulation cores outside the interior lapping layer 4, cable core is provided with outer lapping layer 5, copper wire woven shield 6, fluoroplastics restrictive coating 7 outward successively.
Interior lapping layer 4 adopts the high temperature resistance polyester band overlapping wrapped, and the wrapped rate of putting up is not less than 42%.
Outer lapping layer 5 adopts the high-temperature fibre band overlapping wrapped, and the wrapped rate of putting up is not less than 52%.
The structural design of interior lapping layer 4 and outer lapping layer 5 cooperates fluoroplastic insulation layer 3, fluoroplastic insulation layer 7, has improved the fire resistance of cable, has prolonged cable and has got useful life in hot environment.
The operating characteristic of cable and major parameter:
Electric pressure (KV): 0.45/0.75
Withstand voltage test (KV/min): 3.0/5
Conductor allow for a long time maximum operating temperature (℃): 260
Insulation tensile strength median minimum: 13.8 Mpa
Bending radius: be not less than 12 times of the outside diameter of cable.
