Abstract
The utility model discloses a control cable specially for wind power generation. The control cable is characterized in that conductors adopt tinned soft copper wires; an ethylene propylene rubber insulating layer is extruded on each conductor and thus an insulating wire core is formed; multiple insulation wire cores are twisted to form a cable core; the surface of the cable core is sequentially provided from outside to inside with an extruded inside liner layer, an aramid fiber yarn and tinned copper wire braided layer, and an extruded rubber outer sheath layer. The control cable, serving as a control cable specially for wind power generation, has good anti-torsion performance, stretch resistance, oil resistance and anti-ultraviolet resistance in complicated occasions, is low in production cost, simple in process, and at the same time, has functions of signal control and electric energy transmission, and flexibility.
Description
Technical field
The utility model relates to a kind of electrical equipment control cables, relates in particular to a kind of wind power generation Special control cable, belongs to technical field of electric wires and cables.
Background technology
The wind-driven generator private cable, because the environment of wind power generation is abominable, usually be applied to drying, cold, tight heat, moist, the comparatively abominable area of weather conditions such as ultraviolet ray is strong, general multiplex northern area or coastal area in China, weather is cold, and day and night temperature is larger, so the wind-driven generator private cable also must satisfy ambient temperature-45 ℃～+ 50 ℃, and operating temperature is-40 ℃～+ 80 ℃ service condition.Except the performance that satisfies common cable, also must satisfy bending radius little, frequently reverse, ambient temperature and operating temperature be interval large.The while cable will have can carry certain-length deadweight and flexibility, also will have the characteristics such as oil resistant, antiultraviolet, anti-electromagnetic interference.Control cables need to meet the environment of electrical equipment operation as electrical equipment corollary equipment connecting line.Present general category control cables is difficult to satisfy the requirement in this field.
Summary of the invention
The utility model is for avoiding the existing weak point of above-mentioned prior art, a kind of have under complicated occasion good anti-torsion, tension, oil resistant, ultraviolet resistance being provided; Low cost of manufacture, the simple wind power generation Special control cable of technique.
The utility model is that the technical solution problem adopts following technical scheme:
The design feature of the utility model wind power generation Special control cable is that conductor adopts tin annealed copper wire, extrudes the ethylene-propylene rubber insulated layer at described conductor and consists of insulated wire cores; By a plurality of insulated wire cores twisted synthesizing cables, consist of cable conductor; Set gradually from inside to outside inner covering, aramid yarn and the tincopper fuse wire braided armor that extrudes and the rubber external sheath layer that extrudes on the surface of described cable core.
The design feature of the utility model wind power generation Special control cable also is:
Described conductor adopts among the GB/T3956 the 5th kind or the 6th kind of flexible conductor thigh strand and twists again regular lay configuration.
Pitch is 14-18 with the ratio of external diameter in the regular lay configuration of described conductor.
The pitch of described cable conductor is 12-20 with the ratio of external diameter.
The braiding angle of described aramid yarn and tincopper fuse wire braided armor is that 45 °, count are for being not less than 75%.
Described rubber external sheath layer is as material take neoprene rubber, chlorosulfonated polyethylene or haloflex.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model conductor adopts tin annealed copper wire thigh strand, twists regular lay configuration again, has guaranteed the electrical safety performance of cable, good bending property and flexibility, by improving stranded lay ratio, makes that cable is more anti-to be reversed.
2, the load-bearing reinforced layer between cable inner covering and the outer jacket has adopted the aramid fiber yarn of high strength and modulus and tinned copper wire jointly to weave in the utility model, has on the one hand certain drawing-resistant function, has also played shielding and overcurrent protection simultaneously.
3, the cable inner covering is to adopt the plsitive mold production technology to extrude to form in the utility model, makes the structure of cable tightr, improves the stability of the construction of cable, also improves the twisting property of cable.
4, the utility model uses the chloride element rubber class material of high strength, oil resistant, anti-high/low temperature, the better performances such as weather-proof to make external sheath layer, has good low temperature resistant and resistance to wear, and fatigue durability, weather-resistant performance, anti-microbial performance, oil product, chemicals are had fabulous corrosion resistance.Greatly improved cable useful life when free suspension or fixed installation in the dried tower.
5, the utility model has adopted excellent rubber insulation and sheath, finished cable is under-40 ℃ low temperature environment, can stand positive and negative each four transfer to once, windup-degree is 360 °, number of times is no less than 3000 times anti-torsion performance test, and fracture, jacket surface did not crack conductor after cable testing finished; Cable can suitable environment temperature-45 ℃～+ 110 ℃, operating temperature is-40 ℃～+ 110 ℃; Fixed installation is not less than 4 times of the outside diameter of cable, and mobile installation is not less than 5 times of the outside diameter of cable.
