Abstract
The utility model discloses a waterproofing type power cable, including conductor, cladding semiconduction internal shield layer the conductor outside, cladding at semiconduction external shielding layer the insulating layer outside of the outer insulating layer in semiconduction internal shield layer, cladding, soft copper area iron shielded layer that to be located the semiconduction external shielding layer outer, outside being located soft copper area iron shielded layer the metal armor layer and be located the metal armor layer outside the outer jacket, semiconduction internal shield layer, insulating layer and semiconduction external shielding layer are the three -layer and crowd just the three -layer of dry -type crosslinked altogether and crowd altogether layer, the inside and outside side overlapping of soft copper strips iron shielded layer has a semiconduction area that blocks water, and it has the polypropylene separation sleeve to block water the cladding of outband side at the semiconduction, the outer jacket comprises at polypropylene water blocking layer and the PVC outer jacket of cladding outside the polypropylene water blocking layer outside the metal armor layer the cladding. This power cable has improved the block -water performance of cable.
Description
Technical field
The utility model relates to cable, more specifically to a kind of water-resistance electric power cable.
Background technology
Shown in Figure 2, the crosslinked polyetylene insulated stainless steel wire armoured power cable of existing YJV72 copper core, by stranded compact conductor 1, the semiconductive internal shield 2 be coated on outside stranded compact conductor 1, the insulating barrier 3 be coated on outside semiconductive internal shield 2, the semiconductive outer shielding layer 4 be coated on outside insulating barrier 3, the soft copper band metal screen layer 6 be coated on outside semiconductive outer shielding layer 4, the plastic barrier jacket layer 11 be coated on outside soft copper band metal screen layer 6, is coated on the metal armor layers 8 outside plastic barrier jacket layer 11 and the outer jacket 10 be coated on outside metal armor layers 8 is formed.This power cable can be laid in soil or pipeline, cable trough, also can bear certain pulling force, cable itself does not possess water resistance characteristic, in level of ground water, high or long-term area of heavy rainfull moisture very easily oozes people's outer jacket or invades cable inside from the breakage of outer jacket, along the longitudinal diffusion of cable, and radial penetration, fill up cable internal voids, extend to conductor from insulating barrier, cause whole cable to scrap, and accidents caused.
For the problems referred to above, ointment can be adopted to fill cable core technique and to realize under cryogenic blocking water or adopting clad metal watertight composition to cable.But, adopt ointment to fill and need special ointment pad device, its processing technology is loaded down with trivial details, speed of production is low, exist in process of production and produce the defect such as ointment drip and adhesion, in installation cable running, ointment overflows with cable temperature change outlet ointment, impacts cable running safety.When adopting clad metal watertight composition, sheath, aluminium bag and corrugated metalpipe can prevent moisture from immersing completely, but the outside diameter of cable and weight can be made to increase, and there is cable product cost increases, and cable is hardening installs and uses the problems such as inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of water-resistance electric power cable, to improve the block-water performance of cable.
Water-resistance electric power cable described in the utility model, comprise conductor, the semiconductive internal shield be coated on outside conductor, the insulating barrier be coated on outside semiconductive internal shield, the semiconductive outer shielding layer be coated on outside insulating barrier, the soft copper band metal screen layer be positioned at outside semiconductive outer shielding layer, the outer jacket that is positioned at the metal armor layers outside soft copper band metal screen layer and is positioned at outside metal armor layers, described semiconductive internal shield, insulating barrier and semiconductive outer shielding layer are three-layer co-extruded and the crosslinked three-layer co-extruded layer of dry type; Described soft copper band metal screen layer medial and lateral overlap is surrounded with semiconductor waterstop, is coated with polypropylene separation sleeve outside semiconductor waterstop; Described outer jacket is made up of the polypropylene water blocking layer be coated on outside metal armor layers and the PVC outer jacket be coated on outside polypropylene water blocking layer.
Further, described conductor is stranded compact conductor, is filled with waterproofing agent between stranded conductor, guarantees gapless between wire.
Further, described metal armor layers is non-magnetic stainless steel silk armour, and steel wire gap adopts silicone oil coating waterproofing agent.
Water-resistance electric power cable described in the utility model, owing to having said structure, semiconductive internal shield, insulating barrier and semiconductive outer shielding layer are three-layer co-extruded and the crosslinked three-layer co-extruded layer of dry type, metal screen layer medial and lateral overlap is surrounded with semiconductor waterstop, make gapless between lapping layer and insulating barrier, be coated with polypropylene separation sleeve outside semiconductor waterstop to ensure that and hold tightly together between separation sleeve and insulated wire cores, outer jacket is the composite sheath mode of polypropylene water blocking layer and PVC outer jacket, achieves block-water effect.The utility model has that processing technology is comparatively simple, lighter in weight, the advantage such as easy to install.
