The electric wire heart：Use high conductivity material（Copper or aluminium）It is made.According to laying requirement of the use condition to cable softness, every line
The heart may be formed by solid conductor or multiple conducting wires are stranded.2. insulating barrier：Insulating materials as cable should have high exhausted
Edge resistance, high breakdown field strength, low dielectric loss and low dielectric constant.The insulating materials commonly used in cable has oil immersion
Paper, polyvinyl chloride, polyethylene, crosslinked polyethylene, rubber etc..Cable is often classified with insulating materials, such as oil-impregnated paper insulation cable,
Polyvinyl chloride cable, twisted polyethylene cable etc..3. sealing sheath：Protection insulated wire heart is protected from machinery, moisture, moisture, chemistry
The damage of article, light etc..It is general to use lead or aluminium extrusion sealing sheath for the insulation of moisture-sensitive.4. coating is protected：It is used to
Sealing sheath is protected from mechanical damage.It is general that sheath is surrounded as armor using galvanized steel strip, steel wire or copper strips, copper wire etc.
Outside（Claim armored cable）, armor plays a part of electric field shielding and to prevent external electromagnetic wave interference simultaneously.In order to avoid steel band, steel
Silk is corroded by surrounding media, pitch or wrapping macerated jute layer or extruded polyethylene, polychlorostyrene second typically outside them
Alkene set.
The content of the invention
The purpose of the present invention be the technological deficiency for overcoming existing cable there is provided a kind of excellent combination property, while having prominent
The water resistance and the high voltage power transmission power cable of oil resistance gone out.
The high voltage power transmission power cable of the present invention, including core, wrap up the packed layer of the core, are extruded in the filling
Inner sheath outside layer, is coated in the first fire resistant coating outside the inner sheath, wrapped wrapped outside first fire resistant coating
Layer, is wrapped in the armor outside the lapping layer, is extruded in the oversheath outside the armor；The core is extruded by conductor
Insulating barrier outside the conductor, is coated in the second fire resistant coating outside the insulating barrier, wrapped in second fire resistant coating
Outer isolation lapping layer, is wrapped in the screen layer composition outside the isolation lapping layer.
As optimization, the high voltage power transmission power cable, the core is extruded in the tinned copper wire by tinned copper wire conductor
Thermoplastic polyester elastomer insulating barrier outside conductor, is coated in the second fire prevention outside the thermoplastic polyester elastomer insulating barrier
Coating, the wrapped Kapton Tape isolation lapping layer outside second fire resistant coating is wrapped in the Kapton Tape
The tin-coated copper mesh grid tube shield layer composition isolated outside lapping layer.
As optimization, the high voltage power transmission power cable includes the netted gasket for packing packed layers of PP of the parcel core, extruded
TPUE rubber inner sheath outside the netted gasket for packing packed layers of the PP, is coated in the thermoplastic poly ammonia
The first fire resistant coating outside ester elastomer rubber inner sheath, the wrapped pet mylar tapes outside first fire resistant coating
Lapping layer, is wrapped in the steel-tape armouring layer outside the pet mylar tapes lapping layer, is extruded in poly- outside the steel-tape armouring layer
Olefin elastomer oversheath.
As optimization, the first fire resistant coating and the second fire resistant coating are made up of the component of following parts by weight：Acrylic acid
It is 52~58 parts of modified alkyd resin, 32~35 parts of waterborne polyurethane resin, 2~3 parts of yttrium aluminate of 40nm nanometers of average grain diameter, average
20 μm of particle diameter, 4~5 parts of hydroxyapatite, 3~4 parts of diacetyl tartarate list double glyceride, coco amine APEO 2~3
Part, 1~1.2 part of ethylal, 12~14 parts of 800 mesh precipitated calcium carbonate of granularity, the mesh dolomite dust 15~16 of granularity 1500
Part, 3~4 parts of average grain diameter 50nm nanometer tungsten carbides, 1.5~1.8 parts of aluminate coupling agent, 2~3 parts of triethyl citrate, ring
6~8 parts of hexitol phosphate.
The fireproof coating of first fire resistant coating and the second fire resistant coating, is made up of following steps：
(1) by weight by 40nm nanometers of yttrium aluminates of average grain diameter, 20 μm of hydroxyapatites of average grain diameter, biacetyl wine
The single double glyceride of stone acid, coco amine APEO, ethylal, 5 minutes are stirred with magnetic stirrer, then 60~
70 DEG C ultrasonically treated 30 minutes；
(2) the mesh precipitated calcium carbonate of granularity 800, the mesh dolomite dust of granularity 1500, average grain diameter 50nm are received by weight
Rice tungsten carbide, aluminate coupling agent, triethyl citrate, are well mixed；
(3) by weight by acrylic acid modified alkyd resin, waterborne polyurethane resin, add in vertical mould wash mixer
Stir, the mixture then added in step (1) is stirred 20 minutes under the conditions of 80~90 DEG C, then adds step (2)
In mixture stirred 10 minutes under the conditions of 91~98 DEG C, finally under the conditions of 40~50 DEG C, add inositol phosphate
Stir ten minutes.This fireproof coating use special filler and auxiliary agent, by heat energy formation carburization zone have quality it is closely knit,
Thermal conductivity factor is low, the characteristics of fire protecting performance is good, has reached the fire prevention durability for only selecting one or several single fillers not reach completely.
In addition, also having unexpected oil resistant and ageing-resistant performance, the fireproof coating can be made to have oil in wet environment or cable base material
Can also normal operation in the case of dirt.
The high voltage power transmission power cable of the present invention, employs special structure design, and the exsertile fire resistant coating of property,
Therefore with prominent physics, mechanical performance and heatproof flame-retardant performance, disruptive field intensity, elongation at break, tensile strength, impact bullet
