The utility model relates to a shipboard power cable, the low cost just insulates, the resistance to corrosion is strong.

Description

Ship power cable

Technical field

The utility model relates to a kind of power cable, especially relates to a kind of power cable be applied on boats and ships, belongs to field of cable technology.

Background technology

At present, along with the increase of steamer tonnage and increasing of electrified application, the cable that every steamer is laid also gets more and more, and the insulated cable easily more than thousands of kilometer spreads all over full ship; Therefore, the demand of the shipboard cable of low cost is progressively increasing and is proposing higher performance requirement; Simultaneously for the insulated power cable be applied on outer boats and ships because Long Term Contact wet environment even may be immersed in water, possess except the general performances such as conventional control cable electrical insulating property, electromagnetism interference except needs, also need to possess the performances such as excellent water resistance and nontoxic, low smoke, zero halogen, in addition, also need to possess good mechanical performance, to tackle the test of all kinds of external forces such as towing, tractive, impact.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, a kind of low cost is provided and insulation, ship power cable that resistance to corrosion is strong.

The purpose of this utility model is achieved in that

A kind of ship power cable, described ship power cable includes core cable, described core cable is wound around by two aluminum-alloy wires and forms, described core cable is wound around twining package tape outward and forms lapping layer, and between core cable and lapping layer, fill filler formation packed layer, described lapping layer is outside equipped with screen, and described screen is outside equipped with armour, and described armour is outside equipped with restrictive coating; In described packed layer, interval arranges multiple temperature sensor and water sensor, and the signal lead-out wire of temperature sensor and water sensor is embedded in packed layer along cable length direction.

A kind of ship power cable of the utility model, the material forming the twining package tape of lapping layer is that chemical fibre substrate surface is attached with polyacrylamide amine layer.

A kind of ship power cable of the utility model, the inserts forming packed layer is magnesium oxide mineral powder.

A kind of ship power cable of the utility model, the material of described screen is electric isolution paper.

A kind of ship power cable of the utility model, described armour is the armouring cover become by braided steel wire.

A kind of ship power cable of the utility model, described restrictive coating is halogen-free anti-flaming polyolefin sheath.

Compared with prior art, the beneficial effects of the utility model are:

The utility model adopts aluminium alloy silk thread to substitute conventional copper cash, greatly reduces the production cost of cable; Meanwhile, by the design of packed layer, screen, armour and restrictive coating, improve insulation and the resistance to corrosion of cable.

Accompanying drawing explanation

Fig. 1 is the sectional view of a kind of ship power cable of the utility model.

Wherein:

Core cable 1, lapping layer 2, packed layer 3, screen 4, armour 5, restrictive coating 6.

Embodiment

See Fig. 1, a kind of ship power cable that the utility model relates to, described ship power cable includes core cable 1, described core cable 1 is wound around by two aluminum-alloy wires and forms, the outer twining package tape that is wound around of described core cable 1 forms lapping layer 2, and fills filler formation packed layer 3 between core cable 1 and lapping layer 2, and described lapping layer 2 is outside equipped with screen 4, described screen 4 is outside equipped with armour 5, and described armour 5 is outside equipped with restrictive coating 6;

The material forming the twining package tape of lapping layer 2 is that chemical fibre substrate surface is attached with polyacrylamide amine layer, polyacrylamide has stronger water-swelling property, therefore when moisture enters after in cable, polyacrylamide coated by waterstop surface can sharply expand, thus filling gap, stop the continuation of moisture to be infiltrated;

The inserts forming packed layer 3 is magnesium oxide mineral powder, fill magnesium oxide and make cable have good fire protecting performance, and cost is lower, makes cable product have higher cost performance.

The material of screen 4 is electric isolution paper, and electric isolution paper can reduce the impact of electrostatic interference effectively, and has cold-resistant, high temperature resistant, the characteristic such as acid and alkali-resistance, waterproof;

Described armour 5 is the armouring cover become by braided steel wire, is not only served the effect strengthening cable machinery intensity, also coordinate the good electric magnetic shield performance achieving cable with electric isolution paper by the armouring of braided steel wire;

Described restrictive coating 6 is halogen-free anti-flaming polyolefin sheath;

Preferably, in packed layer 3, multiple temperature sensor and water sensor can be set at interval, and the signal lead-out wire of temperature sensor and water sensor is embedded in packed layer 3 along cable length direction, for the Timeliness coverage when temperature is too high or infiltration occurs.

In addition: it should be noted that above-mentioned embodiment is only a prioritization scheme of this patent, any change that those skilled in the art does according to above-mentioned design or improvement, all within the protection range of this patent.
