Abstract
The utility model discloses a ship power cable with a rated voltage of 0.6/1kV or below. With utilization of the ship power cable, defects of poor oil resistance and weather resistance, low mechanical strength, no flame-resistance effect, low cable security and reliably, and short service life and the like of the existing power cable for ships currently can be overcome. And the provided ship power cable has the characteristics of environment protection, inflaming retarding, low-smoke and halogen-free property, good weather resistance and oil resistance, and good wearing resistance. The ship power cable comprises a cable core including a plurality of wire core conductors arranged in a filling body; conductor insulation layers are arranged at the outer walls of the wire core conductors; and the plurality of wire core conductors are arranged and are formed by twisting. Besides, a cable belting layer, a cable inner sheath layer, a cable armoured layer, and a cable outer sheath layer successively coat the outer wall of the filling body from inside to outside.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of rated voltage 0.6/1kV and following warship ship power cable.
Background technology
The warship ship power cable oil resistance of producing at present both at home and abroad is poor, weatherability is poor, mechanical strength is low, not fire-retardant, cause the cable security reliability to reduce and the problem such as shortening in useful life, be not suitable for use for a long time on naval vessel.
Chinese patent application CN101834027A discloses a kind of low-smoke zero-halogen low-toxicity light power cable for ships and warships, it comprises three groups of cores, three groups of core outsides set gradually band, cross-linked polyolefin inner sheath, armour and cross-linked polyolefin oversheath from inside to outside, between three groups of cores and band, the polyethylene foamed inserts is set, every group of core is comprised of tinned copper conductor and the outer polyolefin insulation layer of tinned copper conductor respectively.This patent insulation adopts polyolefine material, and the specific insulation of polyolefine material own is little, insulation resistance is little, and under moist environment, insulation is water suction easily, causes insulation resistance to descend, and insulation property are difficult to guaranteed.
Chinese patent application CN103137263A discloses a kind polyethylene ship power cable, comprise that many eradication edge cores wrap up twining package tape, screen, armour, restrictive coating after stranded from the inside to the outside successively, be provided with inserts between described insulated wire cores and twining package tape, described every eradication edge core comprises the three-layer co-extruded insulating barrier that conductor is outer with being wrapped in conductor, and described three-layer co-extruded structure is followed successively by conductor screen, dry chemical crosslinked polyethylene, insulation shielding from the inside to the outside.This patent insulation adopts three-layer co-extruded insulating barrier, and insulation thickness is large, and the finished cable external diameter is large, has increased cost on the one hand, is unfavorable for that on the other hand cable lays in small space.This patent insulating sheath material is crosslinked is physics, chemical crosslinking, with the cross-linking radiation of my company, compares, and all there is a big difference for electric property, mechanical performance and stability.
The utility model content
The purpose of this utility model, exactly for overcoming above-mentioned the deficiencies in the prior art, provides a kind of rated voltage 0.6/1kV and following warship ship power cable, and this cable has the feature of environmental protection, anti-flammability, low smoke, zero halogen, weatherability, oil resistance, the characteristics such as resistance to wear.
For achieving the above object, the utility model adopts following proposal:
A kind of rated voltage 0.6/1kV and following warship ship power cable, it comprises cable core, and cable core comprises and is arranged in obturator the some core conductors that meet the 2nd class tinned copper conductor requirement in GB3956, and the outer wall of every core conductor is equipped with insulating layer of conductor; Stranded the forming of described some core conductor arrangement; Described obturator outer wall wraps up tape for cables layer, cable inner restrictive coating, cable sheath and cable jacket layer from inside to outside successively.
Described tape for cables layer is fire-retardant gluing type glass strap, makes fire resistance more reliable.
Described cable inner restrictive coating is irradiation crosslinking halogen-free low-smoke flame-proof polyolefin inner restrictive coating.
Described cable sheath is the braiding armour, and the braiding armour is tinned copper wire.
Described cable jacket layer is irradiation crosslinking halogen-free low-smoke flame-proof polyolefin external sheath layer.
Described insulating layer of conductor is the IXPE insulating barrier.
The utility model is rated voltage 0.6/1kV and the following warship ship power cable that is applied to naval vessel, the outer wall of every core conductor is IXPE, the insulation property of product have been improved, reduced the loss of energy in transmitting procedure, made in addition the core conductor there are the characteristics of weatherability, resistance to ag(e)ing.Inner sheath is the irradiation crosslinking halogen-free low-smoke flame-proof polyolefin, possesses good anti-flammability, low smoke, zero halogen.Cable jacket is the irradiation crosslinking halogen-free low-smoke flame-proof polyolefin, and protective cover material has the characteristics such as excellent splitting resistance, LSOH anti-flaming, oil resistance, resistance to wear, weatherability.
Tape for cables is fire-retardant gluing type glass strap, makes fire resistance more reliable.
Cable sheath adopts the tinned copper wire braiding, makes the cable tension, anti-ly deflects, the mechanical performances such as lateral pressure resistant, bend resistance are significantly increased, and conduct in addition the effect of Leakage Current simultaneously.
The beneficial effects of the utility model are: environmental protection, and fire-retardant, low smoke, zero halogen, good weatherability, oil resistance is good, and resistance to wear is good.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
