Abstract
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.
