Embodiment Construction

[0032] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0033] Such as figure 1 As shown, the present invention provides a power transmission tower (mainly designed for straight-line towers in this application), which includes a support rod body 10 and a cross arm 30 connected to the support rod body 10, wherein, in order to lower the The weight of the support rod body 10 is increased, which facilitates the transportation, installation and maintenance of the transmission tower in mountainous areas. The material of the support rod body 10 is glass fiber reinforced resin-based composite material.

[0034] The glass fiber reinforced resin-based composite material not only has high strength, light weight, fatigue resistance, etc., is suitable for making the support rod body of the power transmission tower, b...

Abstract

The invention provides a transmission tower. The transmission tower comprises a supporting rod body and a cross arm, wherein the supporting rod body is made of glass fiber reinforced resin matrix composites, and the cross arm is connected with the supporting rod body. According to the transmission tower, the supporting rod body is made of the glass fiber reinforced resin matrix composites, and therefore the transmission tower has the advantages of being high in strength, low in weight, resistant to abrasion and fatigue and capable of effectively solving the technical problem that an existing transmission tower is difficult to transport, install and maintain in a mountain area zone because a supporting rod body is heavy.

Description

technical field [0001] The invention relates to the field of power line installation equipment, in particular, to a power transmission tower. Background technique [0002] The construction of power distribution lines in hilly and mountainous areas is greatly restricted by environmental factors. The cement support poles (commonly known as utility poles) of the commonly used 12M and 15M transmission towers are heavy, and trucks and cranes are required for transportation and assembly. Due to the limitation of the construction area and terrain of the towers in mountainous areas, on the one hand, it is not easy for engineering vehicles to reach the construction site, which brings difficulties to the transportation and installation of transmission towers. On the other hand, accidents are more likely to occur during the construction process. [0003] In addition, the existing transmission towers are not only heavy in weight, but also prone to cracking. At the same time, the cross-a...
