Description
Technical field
A kind of cable is the utility model is related to, especially a kind of ethylene propylene rubber insulated wet type submarine cable.
Background technology
At present, in high-tension electricity transmission line of electricity or submarine cable, frequently with crosslinked polyetylene insulated+lead sheath+highly dense
Spend the HYJQ41 type structures of pe sheath.But larger using the submarine cable external diameter and weight of this structure, cable is more stupid
Weight, production and installation cost are undesirable.Ethylene propylene rubber insulated wet type extra large cable replaces crosslinked polyethylene exhausted using ethylene propylene rubber insulated
Edge, tin-coated copper strip replace lead set, while remove high-density polyethylene outer sheath, allow seawater and it is ethylene propylene rubber insulated directly contact,
While cable performance is ensured, the external diameter and weight of cable are significantly reduced, saves production and the installation cost of cable.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of ethylene propylene rubber insulated wet type submarine cable, is ensureing
While submarine cable performance, the external diameter and weight of cable are significantly reduced, saves production and the installation cost of cable.
In order to solve the above technical problems, technical scheme is used by the utility model：A kind of ethylene propylene rubber insulated wet type
Submarine cable, including power cable, protective layer is coated with power cable, the power cable includes leading from the inside to the outside successively
Body, water blocking layer, conductor shield, insulating barrier, insulation screen and metal screen layer, the insulating barrier is using ethylene propylene rubber insulated
Layer, the metal screen layer use tin-coated copper strip metal screen layer.
Preferably, the water blocking layer is filled with rubber, and is banded with outside rubber semiconductive and blocks water binding strap.
Preferably, the power cable is provided with multigroup.
Preferably, in addition to optical cable.
Preferably, the optical cable is wire armoring reinforced fiber.
Preferably, polypropylene rope is filled between the power cable and optical fiber, power cable and optical fiber are coated with poly-
Propylene rope serving.
Preferably, the polypropylene rope serving is coated with steel wire armor layer.
Preferably, the steel wire armor layer is externally provided with polypropylene rope serving.
A kind of ethylene propylene rubber insulated wet type submarine cable provided by the utility model, has the advantages that：
1st, crosslinked polyetylene insulated+lead sheath+height is substituted using the wet type extra large cable structure of ethylene propylene rubber insulated+tin-coated copper strip
The HYJQ41 type structures of density polyethylene sheath.It is ethylene propylene rubber insulated to replace crosslinked polyetylene insulated, tin-coated copper strip to replace lead set,
Remove high-density polyethylene outer sheath simultaneously, save production stage, saved raw materials for production, reduce production cost.
2nd, conductor, which blocks water, is between elastomeric material is squeezed into connector slots while passing through conductor strand, submarine cable by
Seawater is obstructed when being damaged to external mechanical and enters conductor, is minimized loss.
3rd, it is ethylene propylene rubber insulated to use new imported material, excellent performance.Especially water treeing resistance and can accelerate water imbibition
Can, the requirement in AEIC CS6-82 and ICEA S-68-516 is met respectively.Ensure that insulation with the property after contact with sea water
It can not reduce.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is structural representation of the present utility model；
In figure：Water blocking layer 1, insulating barrier 2, tin-coated copper strip metal screen layer 3, polypropylene rope 4, polypropylene rope serving 5, steel
Silk armor 6, optical fiber 7.
