Abstract
The utility model relates to a medium pressure electric power cable with the functions of water prevention, salt mist prevention and corrosion prevention for silicone rubber sheaths of coastal construction. The utility model is characterized in that a conductor is covered with an inner semi-conduction layer, an insulation material layer and an outer semi-conduction layer which form an insulation layer; the insulation layer is made of crosslinked polyethylene material with excellent electrical property, and the crosslinked polyethylene material is vulcanized in nitrogen gas under high temperature and high pressure; a copper belt shielding layer is covered outside the insulation layer; a filling layer and a winding and covering belt are arranged between the shielding layer and an isolation sleeve; the polyethylene material isolation sleeve with excellent waterproof property is covered outside the winding and covering belt; a double-layer steel strip armoring layer is wound and covered on the isolation sleeve; the armoring layer is extruded and covered with a high strength pull resistant silicone rubber material outer sheath with the functions of water prevention, salt mist prevention and corrosion prevention, and the outer sheath is vulcanized in steam or nitrogen gas or hot air under high temperature and high pressure. The utility model has the characteristics of good waterproof property, good corrosion prevention property, good salt mist prevention property, long service life, etc.
Description
Affiliated technical field
The utility model relates to a kind of cable, especially a kind of coastal construction silicone rubber jacket waterproof, anti-salt fog, anticorrosion medium-pressure power cable.
Background technology
A distinguishing feature of coastal construction is exactly that environment is abominable, and coastal working cable often will steep in water, stands the erosion of seawater etch or coastal steam (salt fog), and is aging easily.
At present, the coastal medium-pressure power cable that generally uses is the cable that crosslinking polyethylene insulated steel band armored pvc sheath is formed, and the cable waterproof poor performance of this structure, resistance to corrosion seawater are poor, anti-salt fog poor performance, and the useful life of cable is short.
Summary of the invention
The suitable coastal working silicone rubber jacket waterproof that the purpose of this utility model provides that a kind of water resistance is good, corrosion resistance and good, anti-salt fog performance reach long service life well, prevent salt fog, anticorrosion medium-pressure power cable.
The technical solution of the utility model is: a kind of silicone rubber jacket waterproof, anti-salt fog, anticorrosion medium-pressure power cable, on conductor, extrude interior semi-conductive layer, insulation material layer and outer semiconducting layer and constitute insulating barrier in three-layer co-extruded mode, conductor and insulating barrier constitute insulated wire cores, outside insulating barrier, coat the copper strips screen that conducts electricity very well, outside screen, coat the good polyethylene separation sleeve of water resistance, wrapped double-deck steel band armour extrudes oversheath outside armour on separation sleeve.
The number of described insulated wire cores is 3 or several, and forms by a plurality of insulated wire cores are stranded, and each insulated wire cores constitutes by conductor and the insulating barrier that is coated on the conductor.
Described semi-conductive layer is a semiconductive material.
Be provided with packed layer and twining package tape between described screen and the separation sleeve.
Described insulating barrier is the cross-linking polyethylene materials of the electrical property excellence vulcanized in the nitrogen of high temperature, high pressure.
Described oversheath is the waterproof of vulcanizing in the steam of high temperature, high pressure or nitrogen or hot-air, anti-salt fog, etch-proof high strength tension silastic material.
The beneficial effects of the utility model are: insulating barrier is after the sulfuration of HTHP nitrogen, by original linear macromolecule structural transformation is space network, cannot not change moltenly insoluble performance into by original fusible solubleness, this has improved operate power, ampacity, working temperature and the useful life of cable greatly.Polythene material has excellent waterproof property, makes the separation sleeve of cable with polythene material, and the water resistance of cable is improved greatly.Adopt double-deck steel-tape armouring, can improve the mechanical performance of cable, greatly improved the shock resistance of cable simultaneously.Silicone rubber jacket has excellent waterproof, anti-salt fog and Corrosion Protection, and the useful life of greatly having improved cable.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, conductor, 2, interior semi-conductive layer, 3, insulation material layer, 4, outer semiconducting layer, 5, screen, 6, packed layer, 7, twining package tape, 8, separation sleeve, 9, armour, 10, oversheath.
Embodiment
As shown in drawings: a kind of silicone rubber jacket waterproof, anti-salt fog, anticorrosion medium-pressure power cable, semi-conductive layer 2, insulation material layer 3 and outer semiconducting layer 4 constitute insulating barriers in extruding with three-layer co-extruded mode on conductor 1, and insulating barrier is the cross-linking polyethylene materials of the electrical property excellence vulcanized in the nitrogen of HTHP.By three conductors be coated on insulating barrier on the conductor and twist together and constitute insulated wire cores.Be outside equipped with copper strips screen 5 at insulating barrier, be provided with packed layer 6 and twining package tape 7 between screen and separation sleeve, order coats the good polyethylene separation sleeve 8 of water resistance, double-deck steel band armour 9 and oversheath 10 successively outside twining package tape 7.Oversheath is the waterproof of vulcanizing, anti-salt fog, etch-proof high strength tension silastic material in the nitrogen of HTHP.
