Abstract
A kind of bank electricity system cable, including cable core, the cable core is twisted by several copper cores and water blocking yarn, the cable core is wrapped with cross-linking radiation polyolefin, the cross-linking radiation polyolefin is externally provided with water-proofing powder, water-proofing powder is externally provided with high temperature vulcanizable silicone, the high temperature vulcanizable silicone is wrapped with polypropylene film, the polypropylene film is wrapped with tin-coated steel mesh grid, the tin-coated steel mesh grid is wrapped with thermoplastic polyurethane oversheath, is equipped with aramid fiber yarn braiding layer in the thermoplastic polyurethane oversheath.Cable provided by the utility model has multiple waterproof material, while having good intensity, wear-resisting anti-tear, is particularly suitable for bank electricity system and uses.
Description
Technical field
The present invention relates to field of cable technology more particularly to a kind of anti-tear resist bending water-proof cables.
Background technique
Bank electricity system is powered without using marine generator group by shore electric power during referring to ship berthing.The bank electricity of harbour
It is debarked by ship and is electrically connected cable and shore connection box to the power electrical apparatus on ship, guarantee is able to satisfy marine electric installation
Power demand.If diesel oil generates exhaust gas in combustion, to periphery using itself diesel-electric set electric supply when naval vessel berthing
Environment pollutes, while efficiency is lower, cost of electricity-generating is higher, is powered with harbour power grid and replaces traditional diesel generator group
Power supply, energy-saving effect is significant, furthermore diesel generating set generates electricity, and vibration and noise are larger, after harbour bank electricity, can also disappear
Except above-mentioned influence, the life comfort of warship person is improved.Bank electricity system is beneficial to energy conservation, emission reduction, noise reduction meet becoming for Green Development
Gesture, environmentally protective aspect are significant.But in use due to bank electricity system, due to the shaking of hull, the blowing of wind,
Gravity etc. can generate dragging to connecting cable, and bending damages cable, simultaneously because institute's use environment liquid to steam ratio is heavier,
Also cable dampness is easily made to cause short circuit.
Summary of the invention
In order to overcome the not resistant to bending deficiency of the existing not anti-tear waterproof of bank electricity system cable, the present invention provides a kind of bank electricity
System cable, the cable not only anti-tear resist bending, can also effectively prevent intrusion of the steam to cable.
The technical solution adopted by the present invention to solve the technical problems is: a kind of bank electricity system cable, including cable core,
The cable core is twisted by several copper cores and water blocking yarn, and the cable core is wrapped with cross-linking radiation polyolefin, the spoke
It is externally provided with water-proofing powder according to cross-linked polyolefin, the water-proofing powder is externally provided with high temperature vulcanizable silicone, the high temperature vulcanized type silicon rubber
Glue is wrapped with polypropylene film, and the polypropylene film is wrapped with tin-coated steel mesh grid, and the tin-coated steel mesh grid is wrapped with heat
Plastic polyurethane oversheath is equipped with aramid fiber yarn braiding layer in the thermoplastic polyurethane oversheath.
Water blocking yarn water-swellable can be effectively prevented water and invade in longitudinal i.e. joint, and cross-linking radiation polyolefin has good
Good insulating properties, at the same it is wear-resisting it is resistance to pull, water-proofing powder also has the characteristic of water-swellable, prevents the intrusion of water, high temperature vulcanized type
Silicon rubber not only insulate, and also has fabulous toughness, enhances the intensity of cable, and the good leakproofness of polypropylene film prevents water
The infiltration of vapour, tin-coated steel mesh grid further increase the whole tensile strength of cable, add in thermoplastic polyurethane oversheath
Aramid fiber yarn braiding layer, the characteristic for making thermoplastic polyurethane oversheath not only keep original insulation wear-resisting, further increases oversheath
The resistance to ability of pullling.
The beneficial effects of the present invention are: the cable has multiple waterproof material, while there is good intensity, it is wear-resisting anti-tear,
It is particularly suitable for bank electricity system to use.
Detailed description of the invention
The invention will be further described with example with reference to the accompanying drawing.
Fig. 1 is structural schematic diagram of the invention.
1. copper core in figure, 2. water blocking yarn, 3. cross-linking radiation polyolefin, 4. water-proofing powders, 5. high temperature vulcanizable silicones, 6. is poly-
Polypropylene film, 7. tin-coated steel mesh grids, 8. thermoplastic polyurethane oversheaths, 9. aramid fiber yarn braiding layers
Specific embodiment
In Fig. 1, a kind of bank electricity system cable, including cable core, 1. copper cores, the hot cross-linking radiation polyene of 2. water blocking yarn 3.
Hydrocarbon, 4. water-proofing powders, 5. high temperature vulcanizable silicones, 6. polypropylene films, 7. tin-coated steel mesh grids, 8. thermoplastic polyurethanes protect outside
Set, 9. aramid fiber yarn braiding layers, the cable core are twisted by 7 copper cores and 12 water blocking yarns, and the cable core is wrapped with spoke
According to cross-linked polyolefin, the cross-linking radiation polyolefin is externally provided with water-proofing powder, and the water-proofing powder is externally provided with high temperature vulcanizable silicone,
The high temperature vulcanizable silicone is wrapped with polypropylene film, and the polypropylene film is wrapped with tin-coated steel mesh grid, the plating
Tin steel mesh grid is wrapped with thermoplastic polyurethane oversheath, is equipped with aramid fiber yarn braiding layer in the thermoplastic polyurethane oversheath.
