Abstract

The utility model provides a frequency converter soft cable suitable for 1,000V and lower than 1,000V for ships and warships, which comprises a plurality of cores; each core comprises a copper conductors formed by twisting a plurality of tin plated copper wires; the outside of the copper conductor is coated with an insulating layer made of a soft cross-linked polyethylene material in an extruding way; the outside of the insulating layer is coated with an insulating shield layer made of an embossed copper strip or copper-plastic composite strip material; a wrapping layer made of a halogen-free, low-smoke, low-poison and fire-resistant material wraps the outsides of the plurality of cores; a filler is filled among the plurality of cores in the wrapping layer; a copper braid mesh layer wraps the outside of the wrapping layer; and the outside of the copper braid mesh layer is coated with a sheath made of a halogen-free, low-smoke, low-poison and fire-resistant cross-linked polyolefin material in an extruding way. The frequency converter soft cable has the advantages of good electrical properties, long service life, small bending radius for laying the cable, convenient mounting and laying of the cable, conservation of a great amount of used space in the ships and the warships, and suitability for rated voltage of high-frequency current.

Description

One kilovolt and following naval vessel frequency conversion flexible cable

Technical field

The utility model relates to technical field of electric wires and cables, specifically is a kilovolt and following naval vessel frequency conversion flexible cable.

Background technology

At present, the common crosslinked polyetylene insulated polyolefin jacket cable of general employing in the Ship System, the permission minimum bend inside radius of cable is 6 times the outside diameter of cable when laying.This is the typical products characteristic of naval vessel with cable, can only be applicable to the frequency of 50Hz, can not satisfy the demand of growing Ship System high-frequency frequency conversion equipment.And the space that requires during this type of cable laying is big, has brought many inconvenience and trouble for the design on naval vessel and construction.

The utility model content

The utility model provides an a kind of kilovolt and following naval vessel frequency conversion flexible cable, its good electric property, long service life, lay bending radius little, be convenient to install and lay and can save a large amount of naval vessels usage space and be applicable to the rated voltage of high-frequency current.

The technical solution of the utility model is:

One kilovolt and following naval vessel frequency conversion flexible cable, include several cores, described core includes copper conductor, copper conductor is extruded with insulating barrier outward, described several core is surrounded with the lapping layer that low smoke, zero halogen low-poison and combustion-resisting material is made outward, be filled with filler between several cores in the lapping layer, lapping layer is extruded with the oversheath that low smoke, zero halogen low-poison and combustion-resisting cross-linked polyolefin material forms outward, it is characterized in that: described copper conductor is by many tinned copper wire stranded compositions, the insulating barrier of described core is surrounded with insulation screen outward,, be surrounded with the copper wire woven mesh layer between described lapping layer and the oversheath.

A described kilovolt and following naval vessel frequency conversion flexible cable is characterized in that: described insulation screen selects the embossing copper strips for use or compound copper-plastics band is wrapped forms outside insulating barrier.

The beneficial effects of the utility model are: owing to wrapped embossing copper strips or compound copper-plastics band on the insulating barrier, copper wire woven mesh layer on lapping layer, make the electromagnetic induction of this cable itself not produce interference to external world, this frequency-changing cable be can be used in the higher circuit of frequency, cause even frequency wherein whetstone mutually disappears, the odd frequency can rely on the knot title property elimination of cable, and clutter can rely on screen to eliminate, also can fully eliminate the interference of outer this cable of bound pair, this all makes this cable electrical performance and useful life all be greatly improved; Again because conductor adopts many stranded the forming of superfine copper wire, it is 4 times the outside diameter of cable that insulation adopts the flexibility material can make the permission minimum bend inside radius of cable when laying, and can save a large amount of naval vessel usage spaces.

Description of drawings

Fig. 1 is a schematic cross-section of the present utility model.

Embodiment

As shown in the figure, one kilovolt and following naval vessel frequency conversion three core flexible cables, include 3 cores, described core includes by the many stranded copper conductors 1 of forming of tinned copper wire, copper conductor is extruded with the insulating barrier 2 that soft cross-linking polyethylene materials is made outward, insulating barrier 2 is surrounded with the embossing copper strips outward or the compound copper-plastics band material forms insulation screen 3, described 3 cores are surrounded with the lapping layer 5 that low smoke, zero halogen low-poison and combustion-resisting material is made outward, be filled with filler 4 between 3 cores in the lapping layer 5, the lapping layer 5 outer copper wire woven mesh layer 6 that are surrounded with are extruded with the oversheath 7 that low smoke, zero halogen low-poison and combustion-resisting cross-linked polyolefin material forms outside the copper wire woven mesh layer 6.

Claims

1. a kilovolt and following naval vessel frequency conversion flexible cable, include several cores, described core includes copper conductor, copper conductor is extruded with insulating barrier outward, described several core is surrounded with the lapping layer that low smoke, zero halogen low-poison and combustion-resisting material is made outward, be filled with filler between several cores in the lapping layer, lapping layer is extruded with the oversheath that low smoke, zero halogen low-poison and combustion-resisting cross-linked polyolefin material forms outward, it is characterized in that: described copper conductor is by many tinned copper wire stranded compositions, the insulating barrier of described core is surrounded with insulation screen outward, is surrounded with the copper wire woven mesh layer between described lapping layer and the oversheath.

2. a kilovolt according to claim 1 and following naval vessel frequency conversion flexible cable is characterized in that: described insulation screen selects the embossing copper strips for use or compound copper-plastics band is wrapped forms outside insulating barrier.
