Abstract
The utility model relates to a composite insulating cross-arm comprising an epoxide resin insulating tube full of foamed plastic inside and coated by a fluoroplastic polymeric layer outside. The fluoroplastic polymeric layer can be made of polytetrafluoroethylene, fluorocarbon, polyvinylidene fluoride or the like, and the epoxide resin insulating tube is made of glass fiber-reinforced epoxide resin materials. The fluoroplastic polymeric has good hydrophobic property, electrical corrosion resistance,leakage track resistance and superior the insulating ability, and is not easy to combine with water. The fluoroplastic polymeric is also anti-aging, and has thermal insulation and ultraviolet resistance properties or the like. The aerated plastics filled in the insulating tube can prevent water into the tube, further keeping the insulating ability. The composite insulating cross-arm coated by a fluoroplastic polymeric layer outside has the advantages of good insulativity, durable use, free maintenance, high safe reliability or the like.
Description
Technical field:
The utility model relates to ultra-high-tension power transmission line and transformer station and is used to support a kind of composite insulation cross arm with insulated conductor.
Background technology:
Traditional insulator crossarm has angle steel cross-arm, fiberglass cross-arm, and the angle steel cross-arm gets rusty easily, and insulation property are relatively poor; Fiberglass cross-arm bad mechanical strength, aging easily fracture.Chinese patent literature discloses a kind of power circuit cross-arm (patent No. is 99223724.6), and cross-arm is made up of two-layer, and skin is the ambroin layer; The skin of some cross-arm is plastic cement or epoxy resin.That the skin of above-mentioned cross-arm all exists is easily aging, water resistance and shortcoming such as insulation property are poor, uvioresistant is weak, need often go to safeguard, takes place to prevent accident.
The utility model content:
The purpose of this utility model provides a kind of good insulation preformance, long service life, safe and reliable composite insulation cross arm.
Scheme of the present utility model is: comprise the epoxy resins insulation pipe, epoxy resins insulation casing pack foamed plastic, the outer fluoroplastic polymer layer that coats.
The fluoroplastic polymer layer can be made by polytetrafluoroethylene, fluorine carbon or polyvinylidene fluoride material; The epoxy resins insulation pipe is made by the glass fiber reinforced epoxy resin material.The cross-arm cross section is circular, square, rectangle, " L " type, " I " type or " ㄈ " type.
The utility model has the advantages that: the fluoroplastic polymer hydrophobicity is good, is difficult for knot water; Anti-galvanic corrosion damage property and anti-creepage trace are better, and insulation property are superior; And possess anti-aging, high-low temperature resistant, antiultraviolet, characteristics such as anticorrosive.The plastic foam of filling in the insulated tube can prevent to manage interior water inlet and cause decreasing insulating.So coating the composite insulation cross arm of fluoroplastic polymer layer, outer surface has good insulating, advantage such as durable in use, non-maintaining, safe and reliable.
Description of drawings:
Accompanying drawing is the utility model sectional view.
Embodiment:
With reference to accompanying drawing, composite insulation cross arm is formed by three layers, and internal layer is a foamed plastic 1, and the centre is a glass fiber reinforced epoxy resin insulated tube 2, and outermost layer is a fluoroplastic polymer layer 3.Fluoroplastic polymer layer 3 can be made by fluoroplastic polymer materials such as polytetrafluoroethylene, fluorine carbon, Kynoar.The cross-arm cross section is circular, square, rectangle, " L " type, " I " type or " ㄈ " type.
Fluoroplastic polymer contains ultraviolet screener and antiaging agent, and handles and waterproof and dampproof soda acid is handled through heating cure, good insulation preformance, waterproof and dampproof, high-low temperature resistant, uvioresistant, be difficult for aging, anticorrosive.The utility model long service life, dependable performance, fail safe are good, play main insulation or supplementary insulation effect on shaft tower, and lead fixed can be hung insulator string on the insulation cross bar, also can not hang insulator string.
Claims (4)
1, a kind of composite insulation cross arm comprises epoxy resins insulation pipe (2), it is characterized in that the interior filling foamed plastic of epoxy resins insulation pipe (2) (1), the outer fluoroplastic polymer layer (3) that coats.
