Abstract
The utility model discloses and a kind of used for wind power generationly cold-resistantly resistance toly turn round frequency conversion flexible cable, comprise conductor, the first separator, insulating barrier, the second separator, screen, the 3rd separator, sheath from inside to outside successively; Described conductor forms by multiply conductor is stranded in the same way, and screen is made up of tin-coated copper tow and synthetic fiber yarn.The utility model, compared to the heavy seal coat of pure tinned copper wire or copper wire+single fiber-bundles yarn, effectively raises flexibility, and then enhances the resistance to of variable frequency pneumatic electric cable and turn round characteristic; The utility model construction of cable is simple, rationally, what the unique design of screen made the utility model cable resistance toly turns round, anti-interference, compressive property are superior.
Description
Technical field
The utility model relates to new forms of energy field of cables, refers in particular to a kind of used for wind power generationly cold-resistantly resistance toly to turn round frequency conversion flexible cable.
Background technology
Domestic existing frequency-changing cable, resistance to characteristic of turning round does not reach requirement, and cable is short for useful life, and performance can not meet GB/T29631-2013 standard.Along with the development and utilization of wind resource, higher to the grid-connected requirement of Wind power cable, need to carry out frequency-conversion processing to wind power generation, therefore also to have frequency-changing cable used for wind power generation and resistance toly accordingly turn round requirement, under the prerequisite ensureing serviceability, improve the resistance to of cable as far as possible and turn round characteristic, to increase the useful life of cable.Frequency-changing cable used for wind power generation should be able to stand various high and low temperature environment, salt air corrosion, ultraviolet ageing and oils etch requirement.
China's wind-powered electricity generation cable is generally pressed GB/T 29631-2013 " rated voltage 1.8/3kV and following torsion-resisting soft cable for wind power generation " and is produced, and this standard contains only single core non-shielding cable, does not make requirement to band shielding wind-powered electricity generation cable.
Utility model content
The purpose of this utility model is to provide the used for wind power generation cold-resistant resistance to of a kind of GB/T of meeting 29631-2013 standard and turns round frequency conversion flexible cable.
The technical solution of the utility model a kind of used for wind power generationly cold-resistantly resistance toly turns round frequency conversion flexible cable, comprises conductor, the first separator, insulating barrier, the second separator, screen, the 3rd separator and outer jacket from inside to outside successively; Described screen is formed by three strands of tinned copper wires and three bursts of synthetic fiber yarn weavings; Described tinned copper wire dextrad braiding; Described synthetic fiber yarn left-hand braiding.
Described conductor adopts that strand copper wire is stranded in the same way to be formed.
Described tinned copper wire and the synthetic fiber yarn area ratio in unit length is between 1:0.7 to 1:1; Braiding joint is through than between 1.8-5.2.
Described first separator is semiconductive nylon tape; Described insulating barrier is ethylene-propylene rubber mixture; Described second separator and the 3rd is semiconductive cotton tape; Described outer jacket is cold-resistant CPE rubber composition.
Described first separation layer thickness is 0.1mm; Described second separator and the 3rd thickness be 0.3mm.
The utility model adopts technique scheme, and the utility model has the following advantages:
(1) the utility model is compared to the heavy seal coat of pure tinned copper wire or copper wire+single fiber-bundles yarn, effectively raises flexibility, and then enhances the resistance to of variable frequency pneumatic electric cable and turn round characteristic.
(2) the utility model construction of cable is simple, rationally, the design of screen and low temperature resistant sheath makes cable of the present utility model softness, low-temperature torsion resistance, electromagnetism interference, oil resistant, decay resistance superior.
(3) the first separator of the present utility model selects the semiconductive nylon tape of 0.1mm, increases noiseproof feature while playing a very good protection to conductor; Second separator and the 3rd separator select the semiconductive cotton tape of 0.3mm, and cotton tape better softness can play anti-interference and soft effect preferably.
