Abstract
The utility model discloses an ultraviolet-proof cold-resistant cable used for wind power generation. An insulation wire core is formed by a conductor and an insulating layer which extrudes an outside of the conductor. The insulating layer is formed by the conductor, wherein a flame retardant ethylene propylene rubber extrudes the outside of the conductor. Three insulation wire cores are intertwisted as a triangular mode so as to form a cable core. Filling layers are arranged in gaps of the cable cores. A wrapping-tape layer wraps the cable cores and the filling layers. A chloroprene rubber outer sheath extrudes the outside of the wrapping-tape layer. In a place with a subzero 45 degree temperature, a polrvinyl chloride insulation control cable is crisp and can not be installed and can not be twisted frequently. By using the cable of the utility model, the above problem is solved. Besides, softness of the cable is increased. And under the condition of keeping the cable to possess the good softness, intensity of the cable is increased.
Description
Technical field:
The utility model relates to a kind of used for wind power generation antiultraviolet cold resistant cable.
Background technology:
Along with society and expanding economy, the enhancing of mankind's environmental consciousness, when fossil energy is got over poor when general, the world energy sources structure also huge variation is occuring, is developed to renewable energy by non-renewable energy resources, solar energy, wind energy, biomass energy, geothermal energy, oceanic energy etc., become the direction of people's research, in the middle of so numerous energy, wind energy should be most economical, development is also the fastest, a kind of energy that commercialization is the strongest.
At present. the cable of China's wind power generation special use still is in the starting stage.Because the environment of wind power generation is abominable, blower fan is longer service life, and cable constantly rotates with blower fan, performance requirement to cable is higher, so China's wind energy cable is dependence on import always, and expensive, research and develop and the domestic wind energy cable that comes into operation extremely urgent, high-end wind energy cable production domesticization road is shouldered heavy responsibilities.
Wind energy cable mainly refers to apply to engine room inside, cabin and pylon top, pylon bottom to the occasion of tower under casing change place.Its classification mainly contains flexible cable, power cable (fixedly laying and reverse two parts), control cables etc.The environmental quality of wind energy cable operation is long-term moving going in outdoor, vertical unsettled setting up, and frequent torsion the (automatically going off course to wind), contact greasy dirt direct sunlight etc., the marine wind energy cable also will prevent the corrosion of seawater simultaneously.Due to the harshness of cable running environment and condition, so also very high to the requirement of wind energy cable, mechanical strength is high, anti-turning round (softness), vibration resistance and oil resistant, uvioresistant, the requirements such as seawater corrosion resistance.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of used for wind power generation antiultraviolet cold resistant cable, has solved the polyvinyl chloride insulation control cables in the place of subzero 45 ℃, and the cable embrittlement can not be installed and frequent torsion problem; In addition, improve the cable pliability, in the situation that keep cable to have pliability preferably, improved the intensity of cable.
The utility model technical solution problem adopts following technical scheme:
A kind of used for wind power generation antiultraviolet cold resistant cable, consist of insulated wire cores by conductor and the insulating barrier that extrudes outside described conductor, described insulating barrier is extruded outside described conductor by inflaming retarding ethylene propylene rubber and consists of, three described insulated wire cores are with the stranded formation cable core of isosceles triangle, the cable core gap is provided with packed layer, described cable core and packed layer are surrounded with belting layer outward, and described belting layer is extruded with the neoprene oversheath outward.
Described packed layer is filled in the cable core gap by magnesium hydroxide powder and consists of.
Described belting layer consists of outside described cable core and packed layer by fire-retardant netted oxygen barrier band is wrapped.
The sectional area of described conductor is 1.5～300mm
2, stranded lay ratio is less than 10.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model cable conductor adopts the 5th kind of stipulating in GB/T3956 or the 6th kind of soft copper conductor or tinned copper conductor to restraint in the same way stranded forming, and cross-sectional area of conductor is generally 1.5～300mm
2The copper cash mechanical property depends on material selection and processing technology thereof; The copper stranded conductor flexibility depends on diameter and the correlative factors such as direction of lay control and twisting pitch of stranded annealed copper wire.The stranded conductor that the copper line diameter is little, soft, resistance to bend(ing) is good.
Insulating barrier of the present utility model is according to environment for use and cable normal operating temperature, select ethylene-propylene rubber as insulating material, the ethylene-propylene rubber material has remarkable weatherability, anti-ozone, low compression set, good pliability, excellent cold resistance, good electrical insulation capability, good ageing-resistant performance, excellent anticorrosive performance, and nontoxic odorless.Insulating barrier closely is extruded on conductor, and section is without the visible bubble of eyesight and impurity, the outward appearance rounding and easily and conductor peel off.
The fire-retardant netted oxygen barrier band material of the outer employing of cable core and packed layer makes cable core tight and soft.
Oversheath adopts neoprene (CR) material.This material by modification after brittle temperature can reach-45 ℃.By strengthening soft segment molecule amount and the degree of cross linking, increase pliability, make cable become more soft, neoprene (CR) material has very superior mechanical performance, having good uvioresistant, weatherability, high temperature resistant and have again biodegradable environmental-protecting performance, is a kind of desirable cold resistant cable clad material.
