Description
Technical field:
The utility model relates to a kind of cable, specifically a kind of cable for wind power generation.
Background technology:
In wind generator system, cable is the important component part that electric power transfer, signal transmit.Cable for wind power generation should have the performances such as good lower temperature resistance, corrosion resistance, UV resistant, weather-resistant.Cable for wind power generation can be divided into fixing and mobile installation cable by use occasion, mobile with vertical unsettled the laying of cable, and needs frequent torsion, and therefore mobile also should have good anti-torsion and bending property with cable.Cable cover(ing) directly contacts with external environment, and cable is shielded, and it should have good lower temperature resistance and flexibility, to reduce, reverses the internal stress producing, and prevents structural destruction.
Utility model content:
The purpose of this utility model is to provide a kind of cable for wind power generation, and this cable has excellent mechanical property, toughness, has good anti-torsion and bending property.
In order to solve above-mentioned existing technical problem, the utility model is by the following technical solutions: a kind of cable for wind power generation, comprise oversheath, in oversheath, be wrapped in oxygen barrier layer, in oxygen barrier layer, be wrapped in three insulated wire cores, wherein insulated wire cores extrudes separator outward by conductor, and separator outer wrapping insulating barrier and formed, and adds rubber filling layer and add-on type silica gel tackifier between oxygen barrier layer and insulated wire cores.
Described separator consists of polyether-type thermoplastic polyurethane compound.
Described insulating barrier consists of silastic material.
Described oxygen barrier layer consists of low smoke and zero halogen cross-linking radiation polyolefin.
Described oversheath consists of flame resistance polyurethane elastomer material.
Its operation principle: a kind of cable for wind power generation, by conductor, separator, insulating barrier, rubber filling layer, add-on type silica gel tackifier, oxygen barrier layer and oversheath, formed, in the described oversheath being formed by flame resistance polyurethane elastomer material, be wrapped in oxygen barrier layer, in oxygen barrier layer, be wrapped in three insulated wire cores; Oversheath adopts flame resistance polyurethane elastomer material, has that intensity is high, elasticity is large, resistance to wear is good, an excellent properties such as oil resistant, softness, fire-retardant, high-low temperature resistant; Extrude low smoke and zero halogen irradiation crosslinked polyolefin insulating material as oxygen barrier layer, make cable there is good environmental resistance.Insulated wire cores extrudes separator outward by tinned copper conductor, and separator outer wrapping insulating barrier and formed; The insulating barrier consisting of silicon rubber has more excellent thermal endurance and cold resistance, good electrical insulation capability, resistance to ozone aging, oxygen aging, light aging and atmospheric aging; And because its surface of silicon rubber can be low, with many material surfaces be difficult to bonding firmly, changeable because of the operational environment of cable again, make relative sliding between insulated wire cores, have wearing and tearing, in order to fix each core of cable, therefore adopt rubber filling layer and add-on type silica gel tackifier; The separator consisting of polyether-type thermoplastic polyurethane compound has excellent mechanical property, toughness, chemical resistance, low-temperature pliability, water stability and the performance such as windproof, cold-proof, uvioresistant and environmental protection; Tinned copper conductor structurally flexible, toughness are high.
The beneficial effects of the utility model: this cable has excellent mechanical property, toughness, have good anti-torsion and bending property, environmental protection, preferably environmental resistance, intensity is high, elasticity is large, resistance to wear is good, soft, fire-retardant.
Accompanying drawing explanation:
Below by the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, conductor; 2, separator; 3, insulating barrier; 4, insulated wire cores; 5, rubber filling layer; 6, oxygen barrier layer; 7, oversheath.
Embodiment:
Referring to accompanying drawing 1, a kind of cable for wind power generation, comprise oversheath (7), in oversheath (7), be wrapped in oxygen barrier layer (6), in oxygen barrier layer (6), be wrapped in three insulated wire cores (4), wherein insulated wire cores (4) is by the outer separator (2) that extrudes of conductor (1), separator (2) outer wrapping insulating barrier (3) and is formed, and adds rubber filling layer (5) and add-on type silica gel tackifier between oxygen barrier layer (6) and insulated wire cores (4).
Described separator (2) consists of polyether-type thermoplastic polyurethane compound, it can prevent insulation and conductor adhesion, the oxidation that alleviates conductor, makes cable have the performances such as excellent mechanical property, toughness, chemical resistance, low-temperature pliability, water stability and windproof, cold-proof, uvioresistant and environmental protection.
Described insulating barrier (3) consists of silastic material, require cable section without the visible bubble of eyesight and impurity, it makes cable have more excellent thermal endurance and cold resistance, good electrical insulation capability, resistance to ozone aging, oxygen aging, light aging and atmospheric aging.
Rubber filling layer (5) is in order to fix each core of cable, middle space is filled up, changeable due to the operational environment of cable, make relative sliding between insulated wire cores, have wearing and tearing, when cable bend, filler is insulated core compressing, make the outer margin deformation of filler, thereby make cable have crooked durability and reelability, cable can be used under the environment of alternating bending, has improved the environmental suitability of cable; And its surface of silicon rubber can be low, with many material surfaces be difficult to bonding firmly, therefore adopt add-on type silica gel tackifier (5) to play excellent Efficient Adhesive Promotion, improved compactness and the protection effect of cable inside.
Described oxygen barrier layer (6) consists of low smoke and zero halogen cross-linking radiation polyolefin, it has good fire resistance and excellent process industrial art performance, also having feature not halogen-containing, that the amount of being fuming is low, is a kind of fire proofing of environmental type, makes cable have good environmental resistance.
Described oversheath (7) consists of flame resistance polyurethane elastomer material, and cable section is without the visible bubble of eyesight and impurity, the excellent properties such as it makes, and cable has that intensity is high, elasticity is large, resistance to wear is good, oil resistant, softness, fire-retardant, high-low temperature resistant.
