Abstract

The invention discloses a sliver-plated aluminum alloy armoring and insulation shielding flexible cable. The sliver-plated aluminum alloy armoring and insulation shielding flexible cable is composed of control cable cores, grounding cable cores and five layers of outer protection layers. The five layers of the outer protection layers are a butyronitrile insulation layer, a copper strap shielding layer, a silver-plated aluminum alloy armoring layer, a tin-plated copper strap armoring ethylene propylene sheath layer and a chloroprene rubber sheath layer in sequence from interior to exterior. The control cable cores are arranged to be two sets, the interior of each set is provided with three sets of tin-plated anneal copper conductor cable cores, two metallic flexible tubes and three layers of sheath layers. The three layers of the sheath layers are a silver-plated aluminum wire armoring layer, a polyvinyl ethylene propylene insulation layer and a chlorosulfonated ethylene propylene sheath layer. The grounding cable cores are arranged to be two sets and are pressed and wrapped in the gap of the butyronitrile insulation layer. The sliver-plated aluminum alloy armoring and insulation shielding flexible cable is good in insulation effects, strong in stability of the cable cores in the cable, strong in fire resistance performance, suitable for use in the petroleum chemical industry field, strong in tension resistance and capable of achieving an oil-resistance effect.

Description

A kind of silver-plated aluminium alloy armored and insulation shielding flexible cable

Technical field

The invention belongs to field of cables, particularly relate to a kind of silver-plated aluminium alloy armored and insulation shielding flexible cable.

Background technology

Cable is normally by the cable of several or the stranded similar rope of several groups of wires [often organizing at least two]; often organize mutually insulated between wire; and be often twisted into round a center; whole outside is surrounded by the cover layer of high-insulation; but the inner conductor of cable and external protection structure varied; according to different field need especially can be different; the cable used in apparel; if cable insulation is effective; core is strong at cable internal stability; fire resistance is strong, and grease proofing, the resistance to tearing of tension, that has left nothing to be desired.

Summary of the invention

In order to increase the practicality of prior art, the object of this invention is to provide a kind of grease proofing, resistance to tearing of tension, and the strong silver-plated aluminium alloy armored of fire resistance and insulation shielding flexible cable.

The present invention takes following technical scheme to realize: a kind of silver-plated aluminium alloy armored and insulation shielding flexible cable, it is by control cable core, ground connection cable core and five layers of external protection composition, five layers of external protection are followed successively by butyronitrile insulating barrier from inside to outside, copper strip shielding layer, silver coated aluminum alloy armour, tin-coated copper strip pe sheath layer and chloroprene rubber sheath layer, described control cable core is provided with two groups, all be extruded in butyronitrile insulating barrier inner, often organize inside and be provided with three groups of zinc-plated annealed copper conductor thread cores, two metal hoses and three layers of restrictive coating, often organize zinc-plated annealed copper conductor thread core inside and extrude the zinc-plated annealed copper conductor of the six roots of sensation, wrapped one deck low smoke and zero halogen pe sheath layer and a zinc-plated nickel wire drainage thread, it is inner that zinc-plated nickel wire drainage thread is extruded in low smoke and zero halogen pe sheath layer, three layers of restrictive coating are followed successively by silver-plated aluminium wire armour, polychlorostyrene second propylene insulating barrier and chlorosulfonation second propylene restrictive coating, two metal hoses are silver-plated aluminium wire metal hose, squeeze symmetrically and embrace at silver-plated aluminium wire armour, between polychlorostyrene second propylene insulating barrier and chlorosulfonation second propylene restrictive coating, described ground connection cable core is provided with two groups, be extruded in the gap of butyronitrile insulating barrier inside, often organize inside and extrude two groups of silver-plated annealed copper conductor thread cores, often organize silver-plated annealed copper conductor thread core inside and extrude three silver-plated annealed copper conductors.

The long scope of cross-sectional diameter of described zinc-plated annealed copper conductor is 0.5 ㎜ to 0.8 ㎜.

The present invention has following beneficial effect in sum: this kind of cable insulation is effective, and core is strong at cable internal stability, and fire resistance is strong, be applicable to petrochemical industry and use, and pull resistance is strong, grease proofing.
