Abstract
The utility model discloses a kind of multicore distribution armoured cable, include two oval oversheaths connected side by side, cable core one and cable core two is placed with respectively in the inside of two oval oversheaths, described cable core one includes core and S type rubber skeleton, described core includes leading body, described leading body is twisted by tin annealed copper wire bundle to form, polyolefin insulation layer is coated with successively in the outside of leading body, fireproof paint layer and tinned copper wire add aramid yarn woven shield, the core described in double-deck zinc-plated steel-tape armouring layer formation is surrounded by outside by after three leading body bundle strands, core is placed with respectively in the space up and down of S type rubber skeleton.The double-deck zinc-plated steel-tape armouring layer of the utility model has high permeability, and have good Magnetic Shielding Effectiveness, may be used for anti-glitch, and can make armoured cable directly buried installation and avoid poling, can bear mechanical pressure, multicore distributes, stable signal transmission.
Description
Technical field
The utility model relates to field of cable technology, particularly relates to a kind of multicore distribution armoured cable.
Background technology
In order to prevent being subject to mechanical damage, power cable, at outer armored protective layer, forms armoured cable.Cable adds that the object of armour is except strengthening the mechanical protection such as tensile strength, compression strength and increasing the service life; more importantly improve cable interference free performance by shielding protection, in addition can in case pound, press, rack cable sheath after damage core and cause short circuit.The deficiency of existing armoured cable is: armored protective layer tensile strength is lower, and the external force of bearing is large not; Armored protective layer shield effectiveness is poor, can not be used for the occasion that electromagnetic interference is serious; In addition, the cost of armoured cable is higher.
Utility model content
The utility model object is exactly the defect in order to make up prior art, provides a kind of multicore distribution armoured cable.
The utility model is achieved through the following technical solutions:
A kind of multicore distribution armoured cable, include two oval oversheaths connected side by side, cable core one and cable core two is placed with respectively in the inside of two oval oversheaths, described cable core one includes core and S type rubber skeleton, described core includes leading body, described leading body is twisted by tin annealed copper wire bundle to form, polyolefin insulation layer is coated with successively in the outside of leading body, fireproof paint layer and tinned copper wire add aramid yarn woven shield, the core described in double-deck zinc-plated steel-tape armouring layer formation is surrounded by outside by after three leading body bundle strands, core is placed with respectively in the space up and down of S type rubber skeleton, leading body is placed with respectively at the left and right sides of S type rubber skeleton, and outside be coated with successively ellipse scribble the fabric strip of semiconductive colloid and the fire-resistant fireprotection layer of oval Ceramic silicon rubber form described in cable core one, described cable core two includes control conductor, described control conductor is twisted by zinc-plated nickel wire bundle to form, be coated with glass fiber tape after control conductor and round polyester material are torn pair twist of restricting in outside successively and add Ceramic silicon rubber band lapping layer, cable core two described in plastic film lapping layer and LWA light wire armoured flame retardant coating are formed.
The utility model has the advantages that: the double-deck zinc-plated steel-tape armouring layer of the utility model has high permeability, has good Magnetic Shielding Effectiveness, may be used for anti-glitch, and armoured cable directly buried installation can be made and avoid poling, can bear mechanical pressure, multicore distributes, stable signal transmission.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of multicore distribution armoured cable, include two oval oversheaths 1 connected side by side, cable core one and cable core two is placed with respectively in the inside of two oval oversheaths 1, described cable core one includes core and S type rubber skeleton 2, described core includes leading body 3, described leading body 3 is twisted by tin annealed copper wire bundle to form, polyolefin insulation layer 4 is coated with successively in the outside of leading body 3, fireproof paint layer 5 and tinned copper wire add aramid yarn woven shield 6, be surrounded by double-deck zinc-plated steel-tape armouring layer 7 after three leading bodies 3 are restrainted strand in outside and form described core, core is placed with respectively in the space up and down of S type rubber skeleton 2, leading body 3 is placed with respectively at the left and right sides of S type rubber skeleton 2, and be coated with ellipse in outside successively and scribble the fabric strip 8 of semiconductive colloid and the fire-resistant fireprotection layer of oval Ceramic silicon rubber 9 forms described cable core one, described cable core two includes and controls conductor 10, described control conductor 10 is twisted by zinc-plated nickel wire bundle to form, be coated with glass fiber tape successively in outside after control conductor 10 and round polyester material are torn rope 11 pair twist and add Ceramic silicon rubber band lapping layer 12, plastic film lapping layer 13 and LWA light wire armoured flame retardant coating 14 form described cable core two.
