Abstract

The invention provides a 35kV double-circuit tubular composite rod tower. The 35kV double-circuit tubular composite rod tower comprises a metal rod body and a composite insulation rod head, wherein an earth wire cross beam and three square-tube-shaped composite cross beams are fixed to the composite material insulation rod; an earth wire side earthed downlead framework is mounted on the composite material insulation rod; a metal rod body side earthed downlead framework is also mounted at a junction of the metal rod body and the composite insulation rod head; an earthed downlead is mounted between the earth wire side earthed downlead framework and the metal rod body side earthed downlead framework; the distance between the earthed downlead and two ends of each square-tube-shaped composite cross beam is greater than or equal to 0.6m; the distance between the junction of the metal rod body and the composite insulation rod head and a lower phase lead is greater than or equal to 2m. The 35kV double-circuit tubular composite rod tower is applicable to 35kV wires with wide ranges of span distances, is high in universality and high in electric reliability; the lightning protection performance and the antifouling performance of the composite rod tower can be effectively improved.

Description

technical field [0001] The invention relates to a pole tower, in particular to a 35kV double-circuit tubular composite pole tower. Background technique [0002] The tower is an important equipment of the transmission line, and the characteristics of the materials used directly affect the safety, economy and reliability of the line operation. Because steel has the advantages of high strength-to-weight ratio, easy processing and installation, all steel towers are mostly used at home and abroad. However, the all-steel tower also has its own shortcomings such as high quality (higher steel density) and easy corrosion, so it needs to invest a lot of manpower and material resources in the construction, transportation and maintenance of the tower. [0003] In recent years, with the rapid development of electric power technology, scientific research projects on composite towers combined with engineering have been established successively. Composite materials have the characteristic...
