Abstract

The utility model discloses an environmental protection power cable for offshore banks, including insulating cable core, around nonmetal band layer and crowded package the low smoke and zero halogen inner liner in the nonmetal band layer outside of package in the insulating cable core outside, space between the insulating cable core NOT AND metal bag lacing is equipped with the packing, armor and outer armor in the low smoke and zero halogen inner liner outside is equipped with, interior armor includes around the stainless steel armor area and crowded package low smoke and zero halogen fire -retardant sheath in stainless steel armor outband side of package in the low smoke and zero halogen inner liner outside, outer armor includes the glass fiber epoxy armor area and the cable outer jacket of crowded package in glass fiber epoxy armor outband side in the armor outside including the package. This environmental protection power cable, the convenience is laid in the whole light in weight of cable, construction, and the insulation core protection is reliable, is showing the anti destruction and the corrosion -resistant ability that have improved the cable.

Description

A kind of offshore banks environmental-friendly power cable

Technical field

The utility model is related to a kind of power cable, specifically a kind of offshore banks environmental-friendly power cable.

Background technology

The water proof that conventional subsea cable typically to realize cable conductor using sheath sheath is moistureproof, adopts steel wire armour outer layer more Dress plus the outer form simultaneously being coated pitch of fiber are protected.Lead and pitch all can work the mischief to environment and marine organisms.With When, because lead and a large amount of armouring wire are required for special construction using so that submarine cable is very heavy, constructing and lay Ship and equipment, for offshore banks distribution facility, submarine cable is obviously not suitable for and expensive.

Common seawater corrosion resistant cable, lightweight, construction is laid conveniently, but this cable is had no with common cable structure Much difference, simply, more resistant to the corrosion of seawater, this cable machinery low intensity, without it for the jacket material of cable His safeguard measure, then be difficult to stand washing away for a long time of tide and wave, and this construction of cable be simple, radial seal protective Can be poor, when cable sheath breakage, sea water intrusion enters cable core, then the life-span of cable will fall rapidly upon.

Utility model content

For solving above-mentioned technical problem, the utility model provides a kind of offshore banks environmental-friendly power cable, lightweight, apply Work is laid conveniently, and insulated wire cores protection is reliable, and collapse resistance and corrosion resistance are strong.

The technical solution adopted in the utility model is: a kind of offshore banks environmental-friendly power cable, including insulated core, around Wrap in the nonmetallic belting layer outside insulated core and the low smoke and zero halogen inner liner being extruded in outside nonmetallic belting layer, described exhausted Space between edge cable core and nonmetallic belting layer is provided with packing, be provided with outside described low smoke and zero halogen inner liner inner armor layer and Armoured layer, described inner armor layer includes the stainless steel armoring tape outside the wrapped inner liner in low smoke and zero halogen and is extruded in stainless steel Low-smoke halogen-free flame-retardant sheath outside armoring tape, described armoured layer includes the glass fibre epoxy outside the wrapped layer in inner armor Resin armoring tape and the protective coverings of cable being extruded in outside glass-epoxy armoring tape.

Described insulated core includes conductor, is extruded in insulating barrier outside conductor, waterstop outside insulating barrier for the vertical bag With metallo-plastic composite band, outside described metallo-plastic composite band, it is extruded with low smoke and zero halogen sheath.

Described stainless steel armoring tape is two-layer.

The material of described protective coverings of cable is plastics or synthetic rubber.

The utility model has the advantages that: 1, the armoured layer of cable adopts the replacement of glass-epoxy armoring tape common Wire armoring, makes the external diameter of cable less, and cable weight is compared conventional subsea cable and significantly mitigated.2nd, whole cable is used Material is all environmentally friendly, without heavy metal substance and poisonous and harmful material.3rd, the insulated wire cores of cable compare common Seawater corrosion resistant cable has obtained multilayer and has reliably protected, cable go ashore leave intertidal zone or on draw and exceed highest level face When, can be with peeling outer layer glass-epoxy armor, now cable also has one layer of stainless steel armoring tape protection, and cable connects Enter equipment or entrance distribution facility is more easy to construct.4th, the environmental-friendly power cable that this offshore banks lays, insulated wire cores protection can Lean on, significantly improve collapse resistance and the corrosion resistance of cable, even if cable is armoured and all destroyed situation of inner armor Under, remain to make line security reliably run.

Brief description

Fig. 1 is structural representation of the present utility model；

Wherein: 1, conductor, 2, insulating barrier, 3, waterstop, 4, metallo-plastic composite band, 5, low smoke and zero halogen sheath, 6, filling Bar, 7, nonmetallic belting layer, 8, low smoke and zero halogen inner liner, 9, stainless steel armoring tape, 10, low-smoke halogen-free flame-retardant sheath, 11, glass Fibrous epoxy resin armoring tape, 12, protective coverings of cable.

Specific embodiment

In order to deepen, to understanding of the present utility model, to make into one to of the present utility model below in conjunction with embodiment and accompanying drawing Step describes in detail, and this embodiment is only used for explaining the utility model, does not constitute the restriction to protection domain of the present utility model.

As shown in figure 1, a kind of offshore banks environmental-friendly power cable, by wrapped non-after one or more insulated core stranding Metal tape layer 7, extrudes low smoke and zero halogen inner liner 8, between insulated core and nonmetallic belting layer outside nonmetallic belting layer 7 Space be provided with packing 6, low smoke and zero halogen inner liner 8 lateral gap around stainless steel armoring tape 9 of double-baging, in stainless steel armoring tape Extrude low-smoke halogen-free flame-retardant sheath 10 outside 9 and form inner armor layer, coarse pitch is wrapped many outside low-smoke halogen-free flame-retardant sheath 10 Stock glass-epoxy armoring tape 11, the protective coverings of cable 12 finally extruding one layer of seawater corrosion resistance forms armoured layer. The material of protective coverings of cable can be plastics or synthetic rubber.

Wherein, insulated core includes conductor 1, is extruded in the insulating barrier 2 in conductor 1 outside, the vertical bag waterstop in insulating barrier 2 outside 3 and metallo-plastic composite band 4 extrude low smoke and zero halogen sheath 5, and then formed and keep off damp sheath and longitudinal water blockoff structure with metal Insulated core.

The protection of multilayer armouring and the application of the damp sheath of metal gear, significantly improve mechanical strength and the collapse resistance energy of cable Power, makes cable safe and reliable to operation.
