Abstract
The utility model discloses a kind of second the third glue insulation watertight type naval vessel power cable, comprise that three mutual stranded bunchys of insulated wire cores form cable core, three insulated wire cores all adopt conductor outer cladding ethylene-propylene rubber insulated layer to form, gap between conductor outer wall and conductor is provided with fluid sealant one, and the ethylene-propylene rubber insulated layer of every insulated wire cores is coated with fluid sealant two outward; Cable core center is provided with the packed layer that unvulcanised rubber packing forms, gap between unvulcanised rubber packing outer wall and the unvulcanised rubber packing of packed layer is provided with fluid sealant three, cable core is coated with ethylene-propylene rubber sheath, tinned copper wire braiding armour outward successively, tinned copper wire braiding armour is coated with fluid sealant four outward, and tincopper fuse wire braided armor is coated with neoprene rubber external sheath layer.The utility model novel structure, cable is being met before water between conductor copper wire seamlessly between gap and construction of cable unit, meets direction waterproof under high hydraulic pressure (6 ~ 7MPa) and the gas-tight test requirement under 0.3 ~ 0.5MPa.
Description
technical field:
The utility model relates to power cable, relates in particular to a kind of second the third glue insulation watertight type naval vessel power cable.
background technology:
The fast development of the undersea ships such as submarine and deep water equipment, user has proposed requirements at the higher level to longitudinal waterproof of cable, except meeting the direction waterproof performance under high hydraulic pressure (6 ~ 7MPa), also should meet the gas-tight test requirement under 0.3 ~ 0.5 MPa.
Traditional direction waterproof cable is to adopt gap-fill between conductor copper wire to meet blocking water to bring and realizing longitudinal waterproof of wrapped chance water rapid expanding between the water-proofing powder of water rapid expanding and each layer, but this cable still has some gaps between gap and construction of cable unit meeting before water between conductor copper wire, therefore cannot meet the gas-tight test requirement under direction waterproof and 0.3 ~ 0.5 MPa under high hydraulic pressure (6 ~ 7MPa).
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of second the third glue insulation watertight type naval vessel power cable, meets the gas-tight test requirement under direction waterproof and 0.3 ~ 0.5 MPa under high hydraulic pressure (6 ~ 7MPa).
The technical solution of the utility model is as follows:
Second the third glue insulation watertight type naval vessel power cable, comprise that three mutual stranded bunchys of insulated wire cores form cable core, it is characterized in that: three described insulated wire cores all adopt conductor outer cladding ethylene-propylene rubber insulated layer to form, gap between described conductor outer wall and conductor is provided with fluid sealant one, and the ethylene-propylene rubber insulated layer of every insulated wire cores is coated with fluid sealant two outward; Cable core center is provided with the packed layer that unvulcanised rubber packing forms, gap between unvulcanised rubber packing outer wall and the unvulcanised rubber packing of packed layer is provided with fluid sealant three, cable core is coated with ethylene-propylene rubber sheath, tinned copper wire braiding armour outward successively, tinned copper wire braiding armour is coated with fluid sealant four outward, and tincopper fuse wire braided armor is coated with neoprene rubber external sheath layer.
Described second the third glue insulation watertight type naval vessel power cable, is characterized in that: described conductor adopts the stranded tinned copper conductor of 2 class.
Described second the third glue insulation watertight type naval vessel power cable, is characterized in that: described cable core through extrusion moulding in ethylene-propylene rubber sheath, gapless between cable core and ethylene-propylene rubber sheath.
The utility model has the advantages that:
The utility model structural design is new reasonable, be provided with fluid sealant by many places such as the gap location between conductor outer wall and conductor, ethylene-propylene rubber insulated layer outer wall, packed layer, tinned copper wire braiding armours, make cable meet before water between conductor copper wire seamlessly between gap and construction of cable unit, meet the gas-tight test requirement under direction waterproof and 0.3 ~ 0.5 MPa under high hydraulic pressure (6 ~ 7MPa).
brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to accompanying drawing:
Second the third glue insulation watertight type naval vessel power cable, comprise that three mutual stranded bunchys of insulated wire cores form cable core, three insulated wire cores all adopt conductor 1 outer cladding ethylene-propylene rubber insulated layer 2 to form, gap between conductor 1 outer wall and conductor is provided with fluid sealant 1, the outer fluid sealant 24 that is coated with of ethylene-propylene rubber insulated layer 2 of every insulated wire cores; Cable core center is provided with the packed layer 5 that unvulcanised rubber packing forms, gap between unvulcanised rubber packing outer wall and the unvulcanised rubber packing of packed layer 5 is provided with fluid sealant 36, cable core is coated with ethylene-propylene rubber sheath 7, tinned copper wire braiding armour 8 outward successively, tinned copper wire braiding armour 8 is outer is coated with fluid sealant 49, and tincopper fuse wire braided armor 8 is coated with neoprene rubber external sheath layer 10.
Conductor 1 adopts the stranded tinned copper conductor of 2 class, and flexibility is good.
Cable core forms solid entirety in ethylene-propylene rubber sheath 7 through extrusion moulding.
