A layer of mica tape is lapped on a single conductor and an insulation layer is extruded on the mica tape and then an insulation screen layer is lapped on the mica tape to form one single wire core and filler is filled between the two or more than two wire cores and a lapping layer is lapped on the periphery of the filler and a weaving layer is weaved on the lapping layer and an outer sheath is lapped on the weaving layer and the conductor is tinned copper wire conductor. The insulation layer is formed by injection molding of cross-linked polyethylene and the insulation screen is formed by aluminum plastic belt material and the filler is dust-free rock-wool rope and the lapping layer is formed by the low-smoke halogen-free low-toxicity fire retardation belt material and the fire retardation belt is glass fiber thread belt and the weaving layer is formed by weaving zinc coated wire and the outer sheathe is formed by the low-smoke halogen-free low-toxicity fire retardation cross-linked polyolefin material.
Description
Technical field
The utility model belongs to technical field of electric wires and cables, refers in particular to the fire-resistant frequency-changing cable of a kind of 3kV and following naval vessel.
Background technology
Present stage, the structure of the general frequency-changing cable that uses is extruded insulation and a lapped insulation shielding composition core on single copper conductor on the naval vessel, fill filler in the periphery, at the peripheral wrapped lapping layer of filler, weave the copper wire braid and extrude oversheath, insulation is crosslinked polyetylene insulated or rubber-covered, sheath is polyolefin jacket or rubber sheath, the permission minimum bend inside radius of cable is 8 times the outside diameter of cable when laying, the space that requires is big, has brought many inconvenience and trouble, insulation and sheath non-refractory for the design on naval vessel and construction, and the general mica tape of no use of this type of cable is wrapped on conductor, does not play fire-resistant effect; Braid is ordinary steel wire braiding, and tension, compression strength are little, and useful life is short, and this frequency-changing cable can not satisfy the needs of growing Ship System high-frequency frequency conversion equipment.
Summary of the invention
The purpose of this utility model provides that a kind of fire resistance height, high temperature resistant, good electric property, tension, compressive property are strong, long service life, lay bending radius little, be convenient to install and lay and can save a large amount of naval vessels usage space, be applicable to the fire-resistant frequency-changing cable of rated voltage 3kV and following naval vessel of high-frequency current.
The purpose of this utility model is achieved in that
The fire-resistant frequency-changing cable of 3kV and following naval vessel, it is characterized in that: be at the wrapped one deck mica tape of the outer surface of single conductor, extrude a layer insulating successively and one deck lapped insulation screen is formed single core at the outer surface of mica tape, between two or two above cores, fill inserts, at the wrapped one deck lapping layer of inserts outer surface, outside lapping layer, weave one deck braid, outside braid, extrude one deck oversheath.
Above-mentioned conductor is the tinned copper wire conductor.
Above-mentioned insulating barrier is injection molded through 125 ℃ of cross-linking radiations with crosslinked polyethylene.
Above-mentioned insulation screen aluminium plastic composite strip material forms.
Above-mentioned inserts is dustless mineral wool rope.
Above-mentioned lapping layer is the low smoke, zero halogen low-poison and combustion-resisting band made from glass fiber.
Above-mentioned braid is to form with the zinc-coated wire braiding.
Above-mentioned oversheath is formed by low smoke, zero halogen low-poison and combustion-resisting cross-linked polyolefin material.
The outstanding compared to existing technology advantage of the utility model is: because the utility model adopts braiding zinc-coated wire braid; make cable itself have the effect of electromagnetic radiation shielding; this frequency-changing cable be can be used in the higher circuit of frequency; because of even frequency wherein can be cancelled out each other; the odd frequency can rely on the symmetry of cable to eliminate; and clutter can rely on screen to eliminate; can also fully eliminate the interference of outer bound pair cable; this all makes this cable electrical performance and useful life all be improved; it is 4 times the outside diameter of cable that insulation adopts the flexibility material can make cable allow the minimum bend inside radius when laying; can save a large amount of naval vessel usage spaces; wrapped mica tape lapping layer on conductor; has fire-resistant effect; braid has mechanical protection with the zinc-coated wire braiding; tension; resistance to compression, this cable also have the characteristics of low smoke, zero halogen low-poison and combustion-resisting.
