Abstract
The invention discloses a cross arm for wire pole wiring. The cross arm comprises a cross arm supporting layer, glass fibers, a waterproof foamed plastic resistance body filled in the cross arm supporting layer, a first uvioresistant layer and a second uvioresistant layer, the first uvioresistant layer and the second uvioresistant layer are coated on the cross arm supporting layer, the glass fibers are continuously wound on the cross arm supporting layer to form a square tubular object, and the waterproof foamed plastic resistance body filled in the cross arm supporting layer is identical with the glass fibers in dielectric factor to be used as equipment on a wire pole of an overhead power system to support load. By combining multiple insulating materials, the cross arm is enabled to be light in weight and have effect of being resistant to environmental aging and polluting, so that wiring safety and power supply reliability are improved.
Description
Technical field
The present invention relates to electric pole stringing cross-arm, relate in particular to a kind of combination by multiple insulation materials, make the lighter electric pole stringing cross-arm of weight of cross-arm.
Background technology
Traditional electric pole stringing cross-arm, is using timber or FRP material as cross-arm, because the greenhouse phenomenon of global weather causes ultraviolet ray and temperature to increase, traditional cannot meet demand using timber or FRP material as cross-arm.
Summary of the invention
The object of the invention is to be to provide a kind of electric pole stringing cross-arm, by the combination of multiple insulation materials, make the weight of cross-arm lighter, and possess the effect of anti-environmental aging, pollution, improve stringing safety and the reliability of powering.
According to an aspect of the present invention, a kind of electric pole stringing cross-arm is provided, comprise cross-arm supporting layer, glass fiber, be filled in the water proofing property foamed plastic resistance body of cross-arm supporting layer and be coated in the first uvioresistant layer and the second uvioresistant layer of cross-arm supporting layer, glass fiber continuous winding is in cross-arm supporting layer, to form square tube, the water proofing property foamed plastic resistance body that cross-arm supporting layer is filled is and the water proofing property foamed plastic resistance body of glass fiber same dielectric substrate coefficient, supports loading to use to be provided as equipment on the electric pole of making somebody a mere figurehead power system.
In some embodiments: be coated in the uvioresistant layer of cross-arm supporting layer, with the one-body molded practice of pyrocondensation die casting, and made with ultraviolet ray-resistant material.
In some embodiments: the both ends open of cross-arm supporting layer seals with lid.
In some embodiments: lid is made with the macromolecular material such as glass fiber or polyethylene.
In some embodiments: cross-arm support layer surface can be made into the beveled structure of evagination, indent.
The present invention is simple in structure, easy to use, by the combination of multiple insulation materials, makes the weight of cross-arm lighter, and possesses the effect of anti-environmental aging, pollution, improves stringing safety and the reliability of powering.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of electric pole stringing of the present invention cross-arm.
The specific embodiment
Below in conjunction with accompanying drawing explanation, the present invention is described in further detail.
As shown in Figure 1, a kind of electric pole stringing cross-arm, comprises cross-arm supporting layer 1, glass fiber 2, is filled in the water proofing property foamed plastic resistance body 3 of cross-arm supporting layer 1 and is coated in the first uvioresistant layer 4 and the second uvioresistant layer 5 of cross-arm supporting layer 1.Glass fiber 2 continuous windings are in cross-arm supporting layer 1, to form square tube, utilize glass fiber 2 light weights, high-intensity mechanical property using the main support as cross-arm supporting layer 1, cross-arm supporting layer 1 inner hollow position, the water proofing property foamed plastic resistance body 3 of filling is and the water proofing property foamed plastic resistance body 3 of glass fiber 2 same dielectric substrate coefficients, and be coated in anti-the first uvioresistant layer 4 and the second uvioresistant layer 5 of cross-arm supporting layer 1, one-body molded with pyrocondensation die casting, and made with ultraviolet ray-resistant material.Cross-arm supporting layer 1 both ends open, is to seal with the made lid 6 of the macromolecular material such as glass fiber or polyethylene, to prevent bird and rainwater intrusion.1 surfacing of cross-arm supporting layer, in the not enough situation of shallow leakage distance, can be made into the beveled structure of evagination, indent, to improve along the shallow leakage distance of face along face in insulation.
By the combination of multiple insulation materials, form square tubulose electric pole stringing cross-arm A, support loading to use to be provided as equipment on the electric pole of making somebody a mere figurehead power system, make the weight of cross-arm A lighter, and possessing the effect of anti-environmental aging, pollution, and the characteristic such as anti-mechanical durability characteristic, resistance to curved, anti-electric stress, galvanic corrosion, improves the reliability of stringing safety and power supply, and then the structure of safety and firmness can be provided, reach the safe bearing load of built on stilts power equipment.And water proofing property foamed plastic resistance body 3 packing materials can make cross-arm A inside be unlikely to occur electric stress concentration phenomenon, and prevent moisture content intrusion cross-arm A inside, cause cross-arm A defective insulation, provide high fiberglass pipe counter-bending mechanical strength ability simultaneously.
In sum, the present invention is simple in structure, easy to use, by the combination of multiple insulation materials, makes the weight of cross-arm lighter, and possesses the effect of anti-environmental aging, pollution, improves stringing safety and the reliability of powering.
The above is only one embodiment of the present invention; it should be pointed out that to those skilled in the art, without departing from the concept of the premise of the invention; can also make some similar distortion and improvement, within these also should be considered as protection scope of the present invention.
