Abstract
The utility model relates to a same core type conductor ship power cable, comprising a wire core formed by at least one conductor which is provided with an insulating layer; the external surface of the wire core is uniformly distributed with a plurality of same core conductors which are covered by insulating belts to form a cable core; the cable core is covered by an oversheath. The same core type conductor ship power cable not only can meet requirements of fault current for cross section, but also can be used as a shielding layer and an armor layer, effects are good; cable anti-traction capability is also improved to a certain degree; the same core type conductor ship power cable is a new cable which has the characteristics of excellent performance, compact structure and higher flame retardation capability and is suitable for ships.
Description
Technical field
The utility model relates to a kind of shipboard cable, relates in particular to a kind of with core formula conductor power cable peculiar to vessel.
Background technology
The modern ships electrifing degree is more and more higher, more and more stronger to the dependence that electric power is supplied with, power supply-distribution system has become one of indispensable important system of modern ships, system not only will guarantee not interrupt the power supply to the boats and ships visual plant under condition of severe, keep higher power supply quality again under the condition of the numerous and diverse variation of operating mode; In order to satisfy boats and ships to the requirement of power supply, not only need the function admirable system equipment, connection is also very important with cable, yet existing cable used for distribution still has the some shortcomings part, 1, interference free performance is poor, when containing higher harmonic components in the electric current that cable itself is carried, cable can produce electromagnetic interference to the electronic equipment around it; Otherwise extraneous electromagnetic interference also can be coupled on the cable core, to the various electric generation electromagnetic interference of joining with cable; 2, one zero short-circuit impedances are big mutually, circuit single-phase short circuit current value is reduced, influence the sensitivity deficiency of head end protective device when single-phase short circuit so that the overcurrent protective device of circuit head end effectively moves, often cause jeopardizing electric equipment and the personal safety of whole system; 3, produce overvoltage under the galvanomagnetic effect effect of powerful lightning current at sea, and cause the damage of insulating barrier or breakdown, even installation armoured cable, have shielding action concurrently, its sectional area is relative deficiency also, 4, the outside dimension crane span structure resource that takies bigger than normal, softness is not flexible inadequately, influences efficient during installation exercise.
Summary of the invention
The utility model provides a kind of compact conformation, good mechanical property, same core formula conductor power cable peculiar to vessel that fire resistance is good in order to overcome the above problems.
The technical solution of the utility model is: this cable comprises a core that reaches with the upper conductor formation that is provided with insulating barrier, the even five equilibrium of described core outer surface arranges many same core conductors, described many constitute cable core with the outer lapped insulation band of core conductor, and described cable core is provided with oversheath outward.
Described core and many are provided with filling with being provided with fire-retardant band and inner cushion layer between the core conductor from the inside to the outside successively between described fire-retardant band and the insulating barrier.
Described conductor is copper or tinned conductor.
Described insulating barrier is the cross-linked polyolefin insulating barrier of high insulation resistance.
Described with core conductor by many copper wires or the tin copper wire is stranded or twine and to constitute, its footpath and radical satisfy with the gap between core conductor cross section and two monofilament and are not more than 2 times of filament diameter.
Described insulation band is the wrapped formation of high insulated nylon band spiral.
Described oversheath is irradiation type low-smoke non-halogen flame-retardant cross-linked polyolefin sheath.
Described inner cushion layer is the low-smoke non-halogen flame-retardant cross-linked polyolefin, and its thickness is 0.8-1.8mm.
The utility model is evenly distributed on mode on insulation or the inner cushion layer with the copper wire of certain diameter, some numbers, not only satisfy the requirement of fault current pair cross-section, while double as screen and armour, respond well, the anti-driving power of cable also has increase to a certain degree, be a kind of function admirable, compact conformation, have higher fire retardancy, be fit to the novel cable that boats and ships use.
