Abstract

The present invention provides a 35kV double-circuit tube-type composite material pole tower, which includes a metal shaft and a composite material insulating pole head. The ground wire crossarm and three square tubular composite material crossarms are fixed on the composite material insulating pole head. The grounding down conductor frame on the ground wire side is installed on the insulating rod head of composite material, and the grounding down conductor frame on the metal shaft side is also installed at the joint between the metal shaft and the insulating rod head made of composite material, and the grounding down conductor frame on the ground wire side is installed A grounding down-conductor is installed between the frame and the grounding down-conductor frame on the side of the metal shaft, and the distance between the grounding down-conductor and the two ends of the square tubular composite material cross arm is ≥0.6m; the metal shaft and the composite The distance between the connection part of the material insulation rod head and the lower phase conductor is ≥2m. The 35kV double-circuit tubular composite material pole tower provided by the invention is suitable for 35kV lines with a wide range of spans, has good versatility, high electrical reliability, and can effectively improve the lightning protection and antifouling performance of the composite material pole tower.

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...
