After using above-mentioned technical proposal, the present invention has the effect of below positive：It is produced according to the method for the present invention Cable be that one kind adapting to photovoltaic project construction installation environment waterborne, have photovoltaic project radial direction waterproof waterborne, longitudinal water-blocking, The specific functions such as antiultraviolet, and can directly be suspended under horizontal plane, the cable of any related accessory is not needed in water.
Specific implementation mode
(embodiment 1)
The preparation method of the straight ac cable of photovoltaic project suspension waterborne,
Step 1：Design the construction of cable；Include power transmission cable core, buoyancy liner, waterstop, radial direction successively from the inside to the outside Waterproof layer, anti-corrosion asphalt layer, oversheath, pulling force reinforcer and anti-corrosion winding rope；
Step 2：Prepare power transmission cable core；
Step 3：Calculate the thickness of buoyancy liner；It is converted according to the volume of buoyancy liner, the volume of buoyancy liner calculates public affairs Formula is：
Wherein, VIt is floatingFor the volume of buoyancy liner, ρIt is floatingFor buoyancy inner lining material density, VWaterFor cable displacement of volume, ρWaterFor water Density, ViFor the volume of every layer of structure of cable, ρiFor the density of every layer of structural material of cable；ρIt is floatingMuch smaller than ρWater；By buoyancy liner It is extruded in the periphery of power transmission cable core or is made after band around the periphery of power transmission cable core；
Step 4：Wrapped one layer of waterstop outside buoyancy liner；
Step 5：Setting closing metal tube is as radial waterproof layer outside waterstop；
Step 6：Set gradually anti-corrosion asphalt layer, oversheath, pulling force reinforcer and anti-corrosion winding rope.
Power transmission cable core for insulated wire cores, buoyancy filler and tightens band from the inside to the outside；Insulated wire cores and buoyancy filler Twisted synthesizing cable；Buoyancy filler is round or fan-shaped.Insulated wire cores are made of conductor and insulation, can be single or multicore, middle pressure It further includes conductor shielding, insulation, insulation shielding, metallic shield that the insulated wire cores of cable are outer in insulation, and metallic shield uses copper strips Or copper wire.Buoyancy filler is a kind of light material that a kind of density is significantly smaller than water, such as inflation expansion type or skeletal support Property polyolefine material.
Buoyancy liner is a kind of light material that a kind of density is significantly smaller than water.Buoyancy liner is extruded in power transmission cable core Periphery or be made after band around the periphery of power transmission cable core.Buoyancy liner plays so that cable has axial block water The invasion of water can be controlled the purpose in effective range by ability to prevent cable from surprisingly intaking.In extrusion type buoyancy liner layer The outer wrapped band structure that blocks water, or in compound one layer of water blocking layer outside pouch-type buoyant belt material, the vertical of water is blocked after playing water-swellable To extension problems.Buoyancy liner and the main buoyancy elements of buoyancy filler group cost cable are provided for cable and are suspended in water Buoyancy.
Each structure of cable is other than electrical, mechaincal wood considers, according to the demand for laying suspension function in the water of cable, The buoyancy for needing to provide much abilities is to meet cable to be suspended in water surface key below.In every layer of structure of cable, electricity Insulation system, anti-corrosion layer structure, outer jacket structure, the density of material of anti-corrosion winding rope structure of cable are close and close less than water Degree can cancel this part-structure so being calculated to simplify, and be not involved in calculating, and emphasis calculates conductor structure, the gold of cable Belong to caliber to waterproof construction, the density of material of pulling force reinforcement structure and volume.The thickness of buoyancy liner is according to buoyancy liner Volume converts, and the volume calculation formula of buoyancy liner is：
Wherein, VIt is floatingFor the volume of buoyancy liner, after the volume for calculating buoyancy liner, by calculating power transmission cable core ruler After very little, so that it may which the thickness for calculating buoyancy liner specifies the thickness of extrusion die or wrapped band by thickness；
ρIt is floatingFor buoyancy inner lining material density, this is material property, and the density of the material will be significantly smaller than the density of water, together To the effect for providing buoyancy in water；
VWaterFor cable displacement of volume, be suspended in horizontal plane according to design cable hereinafter, and it is whole impregnate in water, so Cable displacement of volume is exactly the volume of cable entirety；
ρWaterFor the density of water,
ViFor the volume of every layer of structure of cable,
ρiFor the density of every layer of structural material of cable；ρIt is floatingMuch smaller than ρWater。
Radial waterproof layer is closing metal tube.Close metal tube on be arranged semicircle phase cut type embossing, semicircle radius be 5mm~ 8mm.Radial waterproof layer plays waterproof effect, according to the suspension function of cable, metal tube material using the smaller aluminium of proportion or Aluminum alloy materials.According to the requirement that cable is frequently bended caused by by wave in water, metal tube makes wrinkle shape.Wrinkle has Cyclic annular crepe structure and spiral corrugated structure, wherein longitudinal fire resistance characteristic of cyclic annular crepe structure is stronger.Wrinkle shape is semicircle Phase cut type, and semicircle radius control, between 5mm~8mm, such structural cable can meet in water with wave flexural oscillations Without being damaged by external force.
Erosion resistant coating is one layer of anti-corrosion asphalt of coating, and 10-20 parts of machine oil are added in plain asphalt, thus improves pitch Plastic deformation ability prevents asphalt corrosion resistant layer from cracking and loses the anti-corrosion energy of water-proof metal layer during meeting cable bend Power.
Pulling force reinforcer is that Young's modulus of the more uniform windings in oversheath periphery increases not less than 500GPa glass fibres Strong plastics round bar.Have proportion small with common steel wire ratio in cable, the high feature of intensity is suitble to the laying of suspension cable in water Installation function requirement, plays fixed cable position, provides the function of tension ability.
Anti-corrosion winding rope is polypropylene rope, and winding pitch is the diameter of polypropylene rope.And impregnate anti-corrosion asphalt by whole Processing is frequently wanted oversheath, pulling force reinforcer and anti-corrosion winding rope overall fusion one to meet cable by wave bending It asks.O-hydroxyl-diphenyl ketone phenols UV absorbers are added in pitch simultaneously, can effectively improve the anti-of pitch anti-corrosion increasing Ultraviolet light and aging ability, while pitch anti-corrosion increases entirety and has wrapped up cable outer layer, has also effectively obstructed solar ultraviolet light to cable The ability of internal radiation protects the ageing resistance by ultraviolet light ability of cable.
Particular embodiments described above has carried out further in detail the purpose of the present invention, technical solution and advantageous effect It describes in detail bright, it should be understood that the above is only a specific embodiment of the present invention, is not intended to restrict the invention, it is all Within the spirit and principles in the present invention, any modification, equivalent substitution, improvement and etc. done should be included in the guarantor of the present invention Within the scope of shield.
