Abstract
The invention discloses a wind energy cable, comprising conductors, an insulation cable core and a sheath layer; the insulation cable core is formed by two insulation cable cores I and one insulation cable core II; each insulation cable core I is formed by wrapping an inflaming retarding ethylene propylene rubber insulation layer on the conductor; the insulation cable core II is formed by weaving a tinned steel wire armor layer after the inflaming retarding ethylene propylene rubber insulation layer wraps the conductor. A wrapping belt layer wraps the two insulation cable cores I and the insulation cable core II which are combined; filling layers are arranged between the wrapping belt layer and the insulation layers. The filling layer is made of Mg(OH)2 powder. A neoprene rubber sheath layer wraps the wrapping belt layer. The wind energy cable is simple in structure, convenient to use, good in flexibility and can normally work under the place with the temperature being below 45 DEG C below zero.
Description
Technical field
The present invention relates to cable industry, be specifically related to a kind of wind energy cable.
Background technology
Cable is normally by the cable of several or at least two every group stranded similar ropes that form of several groups of wires, mutually insulated between every group of wire, and be often twisted into round Yi Gen center, whole outside is surrounded by the cover layer of high-insulation.Cable has power cable, control cables, compensating cable, shielded type cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, shipboard cable, aluminium alloy cable etc.They are all made up of sub-thread or stranded conductor and insulating barrier, are used for connecting circuit, electrical equipment etc.
Wind energy cable mainly refers to and applies to engine room inside, cabin and pylon top, the pylon bottom occasion to change place of tower under casing.Wind energy cable is moving going in outdoor for a long time, vertical unsettled setting up, frequent torsion (driftage is to wind automatically), contact greasy dirt direct sunlight etc., due to the harshness of cable running environment and condition, so turn round (softness), vibration resistance and oil resistant, uvioresistant, the requirements such as seawater corrosion resistance to the requirement of wind energy cable also mechanical strength is high, resistance to.
Summary of the invention
The invention provides a kind of wind energy cable of knowing clearly, it is simple in structure, easy to use, and flexibility is good, can be local at subzero 45 DEG C, normally work.
The solution of the present invention is as follows: a kind of wind energy cable, comprise conductor, insulated wire cores and restrictive coating, described insulated wire cores is made up of two insulating core I and an insulated wire cores II, described insulating core I is wrapped with inflaming retarding ethylene propylene rubber insulating barrier by conductor and forms, and described insulated wire cores II is wrapped with and is woven tin plated steel wire armour after inflaming retarding ethylene propylene rubber insulating barrier and form by conductor; Wrapped belting layer after two described insulating core I and an insulated wire cores II combination, is packed layer between described belting layer and insulating barrier, and it is magnesium hydroxide powder that described packed layer adopts material; Described belting layer outside is enclosed with chloroprene rubber sheath layer.
Further, to amass be 1～200mm to described cross-sectional area of conductor
2, stranded lay ratio is for being less than 10.
Further, described belting layer adopts fire-retardant netted oxygen barrier band to form.
Of the present invention simple in structure, easily manufactured, there is good electrical insulation capability, cable flexibility is good; Belting layer adopts fire-retardant netted oxygen barrier band to form, and adopts neoprene (CR) as sheath simultaneously, has solved polyvinyl chloride insulation control cables local at subzero 45 DEG C, and cable embrittlement can not be installed and frequent torsion problem; In addition, improve cable pliability, in the situation that keeping cable to there is good pliability, improved the intensity of cable.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
A kind of wind energy cable, comprise conductor, insulated wire cores and restrictive coating, described insulated wire cores is made up of two insulating core I and an insulated wire cores II, described insulating core I is wrapped with inflaming retarding ethylene propylene rubber insulating barrier 2 by conductor 1 and forms, and described insulated wire cores II is wrapped with and is woven tin plated steel wire armour 3 after inflaming retarding ethylene propylene rubber insulating barrier and form by conductor; Wrapped belting layer 4 after two described insulating core I and an insulated wire cores II combination, is packed layer 5 between described belting layer and insulating barrier, and it is magnesium hydroxide powder that described packed layer adopts material; Described belting layer outside is enclosed with chloroprene rubber sheath layer 6.Described conductor 1 sectional area is 1～200mm
2, stranded lay ratio is for being less than 10; Described belting layer 4 adopts fire-retardant netted oxygen barrier band to form.
Although above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present invention and change and amendment; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection scope of the present invention.
