本实用新型公开了一种防腐耐高温控制软电缆，包括四根内导体、数根外导体，四根内导体、数根外导体外侧均分别包裹有氟塑料绝缘层构成四根内绝缘线芯、数根外绝缘线芯，四根内绝缘线芯绞合成束后外绕包有内绕包层，内绕包层外均匀分布有数根外绝缘线芯后构成缆芯，缆芯外依次设有外绕包层、铜丝编织屏蔽层、氟塑料护套层。本实用新型采用内导体外均匀分布外导体构成缆芯，缆芯有两层绕包层，绕包层的结构设计使得电缆结构紧凑性、耐火性能得到提升，同时电缆的柔韧性优越，延长了电缆的使用寿命。
The utility model discloses an anti-corrosion and high-temperature resistant control flexible cable, which comprises four inner conductors and several outer conductors, and the outsides of the four inner conductors and the several outer conductors are respectively wrapped with fluoroplastic insulating layers to form four inner insulating cores , Several outer insulated wire cores, four inner insulated wire cores twisted into bundles and then wrapped with an inner wrapping layer, and several outer insulated wire cores are evenly distributed outside the inner wrapping layer to form a cable core, and the outside of the cable core is arranged in turn. There are outer wrapping layer, copper wire braided shielding layer and fluoroplastic sheath layer. The utility model adopts the outer conductor uniformly distributed outside the inner conductor to form the cable core. The cable core has two layers of wrapping layers. The structural design of the wrapping layers improves the compact structure and fire resistance of the cable. At the same time, the cable has superior flexibility and extends cable life.
Description
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.
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.
