Abstract

Disclosed in the utility model is a power cable for a ship. The power cable consists of conductors, wire cores, insulated wire cores and a sheath layer. A cable core is formed by combination of six insulated wire cores; and each insulated wire core is formed by wrapping three conductor cores successively by a fireproof mica layer and a flame-retardant wrapping belt layer. The outside of the cable core is successively wrapped with a fireproof mica layer II, a flame-retardant coating layer, a dual-layer flame-retardant wrapping belt layer II and an outer sheath layer made of a halogen-free low-smoke flame-retardant polyolefin material. In addition, six control wire cores are also arranged among the six insulated wire cores; two conductor cores are twisted in a pair and then are wrapped with a flame-retardant wrapping belt layer to form one control wire core; and the conductor cores are formed by wrapping conductors in a manner of extrusion by crosslinking polyethylene insulating layers. Besides, the gap between the cable core and the fireproof mica layer II is filled with a glass fiber rope. According to the scheme, with the cable, when a fire occurs, the flame can be effectively prevented from spreading to the insulating layers, so that the flame-retardant performance is good. Moreover, the blocking property of the power cable is good.

Description

A kind of warship ship power cable

technical field

The utility model relates to a kind of warship ship power cable, belongs to technical field of electric wires and cables.

background technology

Along with the development of shipping industry, especially along with the development of large-tonnage ships technology, also more and more for the cable demand of boats and ships.Along with scientific and technical development, to requiring also more and more higher with the cable of marine equipment.Conventionally flame retardant cable used is substantially all to adopt flame retardant insulation material, fire-retardant band, flame-retardant filler, flame-retardant sheath material.Its deficiency is: in the time of breaking out of fire, cable stops the performance of propagation of flame not strong, and flame easily spreads to insulating barrier.Boats and ships and personnel's safety is caused to very large hidden danger.For shipboard cable, fire resistance requires very high, and the cable of ordinary construction, in the time of ignition of cable, can not effectively stop spreading of flame.

utility model content

The purpose of this utility model is to provide a kind of warship ship power cable, in the time of ignition of cable, can effectively stop flame to spread to insulating barrier, and fire resistance is good, and has stagnant right property.

Scheme of the present utility model is as follows: a kind of warship ship power cable, comprise conductor, core, insulated wire cores and restrictive coating, described cable core is combined by six roots of sensation insulated wire cores, and described insulated wire cores is led core by three, and wrapped fireproof mica layer, fire-retardant belting layer form successively outward; The outer wrapped fireproof mica layer II successively of described cable core, flame retardant coating, double-deck fire-retardant belting layer II and the external sheath layer that adopts halogen-free and low-smoke flame-retardant polyolefin material to make; Between described six roots of sensation insulated wire cores, be also provided with six roots of sensation control core, after described control core is led core pair twist by two, wrapped fire-retardant belting layer forms; The described core of leading extrudes crosslinked polyetylene insulated layer outward by conductor and forms; Between described cable core and fireproof mica layer II, be filled with glass cord.

Further, described conductor structure meets the requirement of the 5th kind of conductor in GB/T 3956, by stranded the forming of 5-80 thigh silver-gilt copper wire.

Further, described thickness of insulating layer is 0.06-0.1mm.

The utility model arranges one deck flame retardant coating, and this coating can improve self-extinguishment, hydrophobicity, sealing, insulating properties of cable etc., and this coating self adhesive force is good, fineness is good.Lead core and cable core fire-resistant female layer that goes is all set outward, can make cable there is better flame retardant effect.

Brief description of the drawings

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

embodiment

A kind of warship ship power cable, comprises conductor, core, insulated wire cores and restrictive coating, and described cable core is combined by six roots of sensation insulated wire cores, and described insulated wire cores is led core by three, and wrapped fireproof mica layer 3, fire-retardant belting layer 4 form successively outward; The outer wrapped fireproof mica layer II 5 successively of described cable core, flame retardant coating 6, double-deck fire-retardant belting layer II 7 and the external sheath layer 8 that adopts halogen-free and low-smoke flame-retardant polyolefin material to make; Between described six roots of sensation insulated wire cores, be also provided with six roots of sensation control core 9, after described control core is led core pair twist by two, wrapped fire-retardant belting layer forms; The described core of leading forms by extruding crosslinked polyetylene insulated layer 2 outside conductor 1; Between described cable core and fireproof mica layer II, be filled with glass cord.

Described conductor 1 structure meets the requirement of the 5th kind of conductor in GB/T 3956, by stranded the forming of 5-80 thigh silver-gilt copper wire.Described insulating barrier 2 thickness are 0.06-0.1mm.

Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and amendment; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
