Row frequency-conversion processing, frequency conversion equipment can be applied to, while meet the cable of offshore oil platform application environment.
Technical scheme：In order to solve the above-mentioned technical problem, a kind of offshore oil platform medium voltage converter of the present invention
Cable, it includes conductor, is extruded outside the conductor provided with semiconductive shielding layer I, is set outside the semiconductive shielding layer I
There is insulating barrier, semiconductive shielding layer II is provided with outside the insulating barrier, copper wire is provided with outside the semiconductive shielding layer II
Screen layer, copper strip layer is provided with outside the shielding layer of copper wires, semiconductive belt is provided with outside the copper strip layer, described half
Inner sheath is provided with outside conductive strip layers, steel wire copper wire is provided with outside the inner sheath and intersects armor, in the steel wire copper wire
Intersect and be provided with oversheath outside armor.
The conductor is tinned copper conductor, and it is soft structure, and synnema lay ratio is less than 14 times, twists lay ratio again and is less than 12
Times.
The semiconductive shielding layer I, insulating barrier and semiconductive shielding layer II is three-layer co-extruded forms.
Copper wire interval in the shielding layer of copper wires is not more than 4mm, and its section of weighing is more than 25mm2。
The copper strip layer it is overlapping it is wrapped form, Duplication is more than 20%, and section of weighing is more than 25mm2。
The semiconductive belt it is overlapping it is wrapped form, Duplication 30%, its thickness is 0.50mm.
Cable conductor uses tinned copper conductor, and conductor uses soft structure, and synnema lay ratio is less than 14 times, and it is small to twist lay ratio again
In 12 times, multiple in the same direction twist to realize that conductor diameter minimizes is used.
Semiconductive shielding layer I outside conductor, insulating barrier, semiconductive shielding layer II is three-layer co-extruded, and semiconductive shielding layer I is half
Conductive rubber section bar material, thickness are about 0.80mm, and insulation uses ethylene propylene diene rubber, and thickness ratio commonly waits the insulation thickness of voltage
Thick 1-2mm, semiconductive shielding layer II are semi-conductive rubber material, and thickness is about 0.80mm.
Inner sheath uses the halogen-free flameproof oil resistant polyolefin of resistance to mud, and tensile strength is more than 10MPa, and elongation at break is more than
180%。
Winding steel wire armouring and copper wire armored are used outside inner sheath, steel wire intersects with copper wire contacts placement, nothing
Gap.
Oversheath uses the halogen-free flameproof oil resistant polyolefin of resistance to mud, and tensile strength is more than 10MPa, and elongation at break is more than
180%。
Beneficial effect：Compared with prior art, its remarkable advantage is the present invention：The present invention uses copper wire outside insulation shielding
Winding and the wrapped shielding of copper strips, and protected using semi-conductive tape, can be with the pulse voltage of frequency conversion equipment, while in armouring
Also copper wire is added in layer, increases shielding properties, inner sheath is extruded using the ethyl-propylene insulating materials of insulation-grade, protects cable core,
The oversheath of cable uses fire-retardant low smoke, zero halogen polyolefine material, ensures the fire-retardant and environmentally friendly performance of cable, suitable for sea
The environment of oil platform.
