Description

A kind of waterproof cable for ship

Technical field

This utility model relates to a kind of cable, is specifically related to a kind of cable for ship.

Background technology

Cable for ship, as the ingredient of ship electrical system, is responsible for as critical functions such as power electrical apparatus power supplys various on ship and signal transmission.Along with naval vessel is electrified and the improving constantly of automaticity, the usage amount of cable for ship is increasing.Existing cable for ship generally exist waterproof, decay resistance is poor, by problems such as external force are easily damaged, thus affects using effect.

Summary of the invention

Goal of the invention: the purpose of this utility model is to overcome deficiency of the prior art, it is provided that a kind of integral waterproofing performance is good, and tensile property is good, waterproof cable for ship safe and reliable to operation.

Technical scheme: in order to solve above-mentioned technical problem, the waterproof cable for ship of one described in the utility model, it includes conductor, it is provided with insulating barrier outside described conductor, it is provided with semiconductive shielding layer outside described insulating barrier, cellosilk braid it is provided with outside described semiconductive shielding layer, they form conductive unit, described insulating barrier and semiconductive shielding layer are co-extruded, described conductive unit is at least provided with two, they circumscribed settings, waterproof packed layer it is provided with outside described conductive unit, it is provided with semiconductor waterstop layer outside described waterproof packed layer, it is provided with cushion outside described semiconductor waterstop layer, it is provided with outer water blocking layer at described buffer exteriors, described outer water blocking layer includes waterproof inner restrictive coating, metal armor layers and external sheath layer.

Described conductor is oxygen-free copper conductor.

Described insulating barrier is tetrachloroethylene hexafluoropropylene copolymer insulating barrier or crosslinked polyetylene insulated layer.

Described cellosilk braid by aramid fiber silk according to 1 repeatedly 2 vertical woven form.

Described waterproof packed layer is light-duty waterproofing rope packed layer.

Described cushion is tensile elastic layer.

Described waterproof inner restrictive coating is water resistant polyurea ethylene restrictive coating.

Described external sheath layer is high-flame-retardanthalogen-free halogen-free low cigarette polyolefin sheath layer.

Beneficial effect: this utility model is compared with prior art, its remarkable advantage is: this utility model overall structure arranges rationally, use waterproof packed layer, semiconductor waterstop layer and outer water blocking layer, it is effectively improved integral waterproofing performance, use cellosilk braid and cushion, substantially increase the tensile property of cable, use insulating barrier and the screen layer of double-layer coextrusion, ensure that the insulating properties of cable, and prevent the generation of water tree, use metal armor layers, reduce the interference that during cable uses, magnetic field is external, each layer connects and coordinates, cable overall volume is little, lightweight, meet cable for ship requirement.

Accompanying drawing explanation

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

Detailed description of the invention

With embodiment, this utility model is further described below in conjunction with the accompanying drawings.

As shown in Figure 1, the waterproof cable for ship of one described in the utility model, it includes conductor 1, it is provided with insulating barrier 2 outside described conductor 1, it is provided with semiconductive shielding layer 3 outside described insulating barrier 2, it is provided with cellosilk braid 4 outside described semiconductive shielding layer 3, they form conductive unit, described insulating barrier 2 and semiconductive shielding layer 3 are co-extruded, described conductive unit is at least provided with two, they circumscribed settings, waterproof packed layer 5 it is provided with outside described conductive unit, it is provided with semiconductor waterstop layer 6 outside described waterproof packed layer 5, it is provided with cushion 7 outside described semiconductor waterstop layer 6, it is provided with outer water blocking layer outside described cushion 7, described outer water blocking layer includes waterproof inner restrictive coating 8, metal armor layers 9 and external sheath layer 10；Described conductor 1 is oxygen-free copper conductor；Described insulating barrier 2 is tetrachloroethylene hexafluoropropylene copolymer insulating barrier or crosslinked polyetylene insulated layer；Described cellosilk braid 4 by aramid fiber silk according to 1 repeatedly 2 vertical woven form；Described waterproof packed layer 5 is light-duty waterproofing rope packed layer；Described cushion 7 is tensile elastic layer；Described waterproof inner restrictive coating 8 is water resistant polyurea ethylene restrictive coating；Described external sheath layer 10 is high-flame-retardanthalogen-free halogen-free low cigarette polyolefin sheath layer.This utility model overall structure arranges rationally, use waterproof packed layer, semiconductor waterstop layer and outer water blocking layer, it is effectively improved integral waterproofing performance, use cellosilk braid and cushion, substantially increase the tensile property of cable, use insulating barrier and the screen layer of double-layer coextrusion, ensure that the insulating properties of cable, and prevent the generation of water tree, use metal armor layers, reduce the interference that during cable uses, magnetic field is external, each layer connects and coordinates, cable overall volume is little, lightweight, meets cable for ship requirement.

This utility model provides a kind of thinking and method; the method and the approach that implement this technical scheme are a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications; these improvements and modifications also should be regarded as protection domain of the present utility model, and each ingredient the clearest and the most definite in the present embodiment all can use prior art to be realized.
