摘要： A composite crossarm fixed on a pole body of a transmission pole is disclosed. The composite crossarm includes: a core rod, an insulating layer and a load-bearing member. The insulating layer and the load-bearing member cover and are fixed to an outer peripheral surface of the core rod. The load-bearing member is positioned in a middle region of the core rod connected to the pole body, and the insulating layer is positioned in regions of the core rod other than the middle region. A transmission pole using the above composite crossarm is also disclosed. In the above manner, the load-bearing member is arranged at a position where the core rod is connected to the pole body in advance. On one hand, the core rod is able to be connected to the pole body without providing with a hole. On the other hand, the load caused by the fixed connection is applied on the load-bearing member directly, with no damage to the insulating layer. Both the load-bearing member and the insulating layer cover and are fixed on the outer peripheral surface of the core rod, so that the core rod is protected from external corrosion, to ensure the mechanical properties of the composite crossarm.

摘要： Disclosed in the present invention is a post insulator, comprising a hollow insulating tube, a shed positioned on periphery of the hollow insulating tube, and an upper flange and a lower flange provided at two ends of the hollow insulating tube, wherein gas is sealed inside of the hollow insulating tube, and the absolute pressure of the gas is 0.1-0.15 MPa. Further disclosed is an insulated support post formed by the end-to-end connection of the post insulators. The post insulator and the insulated support post of the present invention solve an interface problem present in internal insulating solid material filling, and also solve a gas leaking problem that occurs when using high-pressure gas filling, such that the post insulator does not need to be detected and maintained. At the same time, the margin of the micro-water control range is improved, and micro-water control and production difficulty is reduced.

摘要： An overhead power distribution line (10) comprises a tension resistant pole (101), two composite crossbeams (102) and tension resistant fixing members (103). A middle portion of the composite crossbeam (102) is horizontally secured on the tension resistant pole (101), and end portions of the composite crossbeam (102) are connected to the tension resistant fixing members (103). The tension resistant fixing members (103) enable the two composite crossbeams (102) to integrally connect and are for fixing conducting lines. With the above configuration, two composite crossbeams (102) are secured on the same horizontal plane of the tension resistant pole (101), thus satisfying vertical tension of a tension resistant requirement. Further, by using composited crossbeam bodies (102), a dry arc distance is significantly increased, and electrical lightning resistance performance is enhanced, preventing incidents such as line disconnection and flashover caused by lightning strike. The composite crossbeams (102) are maintenance-free and do not require periodical inspection and maintenance, significantly reducing labor costs. The use of crossbeams (102) can further eliminate the use of tension insulators and simplify the structure of lines.
