Abstract

The utility model discloses a high-performance degaussing cable for a warship, belonging to the electric cable technical field, which solves the problems of the prior cable for the warship that the insulation layer is easily corroded and punctured by the microbe parasitism. The high-performance degaussing cable for the warship comprises a degaussing cable, a zero-halogen lapping layer outside a stranding soft copper conductor, a zero-halogen ethylene-propylene rubber layer cladding the outside of the zero-halogen lapping layer, a neoprene inner sheath and an irradiation cross-linked polyethylene outer sheath which clad the zero-halogen ethylene-propylene rubber layer in turn, wherein the thickness ratio of the neoprene inner sheath to the irradiation cross-linked polyethylene outer sheath is 4:1. The diameter of the conductor mono-filament is 0.5mm and the conductor mono-filament is bundled to form a strand along the same direction and the lay ratio of the same-direction stranding is (7-9):1 and the strand is re-stranded to form a stranded soft copper conductor 1 along the reverse direction and the lay ratio of the reverse-direction re-stranding is (10-12):1. The cable decelerates the microbe parasitism corrosion and aging of the cable and the low smoke low-halogen material ensures the environmental protection performance and the human health.

Description

Warship high-performance degaussing cable

Technical field

The utility model relates to a kind of power cable, particularly a kind of warship high-performance degaussing cable.

Background technology

The conductor of cable is coated with insulating barrier outward, because warship is often worked under water with cable, the microbe in the water body is very abundant, and cable contacts water for a long time, and its insulating barrier is outer will to adhere to a lot of microbes.And the erosion of microbe is easy to the insulation-piercing layer, and the safe handling of cable is exerted an influence.

The utility model content

The utility model provides a kind of warship high-performance degaussing cable, to solve in the prior art problem of insulation-piercing layer owing to the erosion of microbe.

For solving above technical problem, a kind of warship high-performance degaussing cable provided by the utility model, stranded soft copper conductor peripheral hardware has the ethylene propylene rubber insulated layer of Halogen, outer neoprene inner sheath and the IXPE oversheath of being coated with successively of the ethylene propylene rubber insulated layer of described Halogen.

With respect to prior art, the utility model has been obtained following beneficial effect: insulating barrier adopts Halogen ethylene-propylene rubber to have excellent flexibility, makes the minimum bending radius of cable reach 4～6 times the outside diameter of cable; The neoprene inner sheath has low cigarette, low halogen, oil resistant, low temperature resistant, wear-resisting waterproof, corrosion resistant characteristics; IXPE oversheath smooth surface, marine microorganism is not easy parasitism, can slow down microbe the parasitism corrosion of cable is worn out; Adopt the low-smoke low-halogen material to guarantee environmental-protecting performance and health of human body.

As improvement of the present utility model, be provided with the Halogen lapping layer between the ethylene propylene rubber insulated layer of described stranded soft copper conductor and described Halogen.The Halogen lapping layer can be kept apart stranded soft copper conductor and insulating barrier, avoids between insulating barrier and the conductor chemical reaction taking place, and reduces the performance of cable.

As preferred version of the present utility model, the monofilament nominal diameter of described stranded soft copper conductor is 0.5mm.

As preferred version of the present utility model, the equidirectional synnema of the monofilament of described stranded soft copper conductor constitutes strand, stranded in the same way lay ratio is (7～9): 1, and the multiple in the other direction strand of described strand constitutes described stranded soft copper conductor, and oppositely the lay ratio of multiple strand is (10～12): 1.The equidirectional synnema of monofilament constitutes strand, and the multiple in the other direction again strand of strand constitutes twisted copper conductors, can avoid in the conductor monofilament silk to occur jumping and make the insulating barrier part thin excessively, causes insulation breakdown.

As preferred version of the present utility model, described neoprene inner sheath is 4: 1 with the thickness ratio of described IXPE oversheath.

Description of drawings

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

Among the figure: 1 stranded soft copper conductor, 2 Halogen lapping layers, the ethylene propylene rubber insulated layer of 3 Halogens, 4 neoprene inner sheaths, 5 IXPE oversheaths.

Embodiment

As shown in Figure 1, warship of the present utility model high-performance degaussing cable, stranded soft copper conductor 1 peripheral hardware has Halogen lapping layer 2, Halogen lapping layer 2 is coated with the ethylene propylene rubber insulated layer 3 of Halogen, be coated with neoprene inner sheath 4 and IXPE oversheath 5 successively outside the ethylene propylene rubber insulated layer 3 of Halogen, the neoprene inner sheath is 4: 1 with the thickness ratio of IXPE oversheath.

Conductor adopts the stranded tin-coated copper conductor of soft junction structure that meets GB/T3956-2008 the 5th class, conductor monofilament nominal diameter is 0.5mm, the earlier equidirectional synnema of conductor monofilament constitutes strand, stranded in the same way lay ratio is (7～9): 1, the multiple in the other direction again strand of strand constitutes stranded soft copper conductor 1, and oppositely the lay ratio of multiple strand is (10～12): 1.

In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
