Abstract：In the process of economic development， the demand for electricity is increasing， and the power grid system continues to expand， and the risks it bears are also increasing， such as tripping， power grid safety accidents， etc.， people are constantly looking for and trying new methods to reduce or even avoid risks. With the continuous progress of technology， the role of composite materials in the power transmission system has become greater and greater. For example， cross arm poles made of composite materials have gradually replaced traditional wooden or metal alloy cross arm poles， which reduces the risk probability and improves the efficiency of the power system. Compared with traditional wooden or metal alloy cross arm poles， the application of composite materials in cross arm poles has certain advantages. This paper calculates and studies the bearing capacity of composite cross arm poles in 10kV distribution lines， and compares them with the actual stress situation， verifies the calculation results， which provides support and basis for the research and design of composite cross arm towers for distribution lines. It is of great significance to the development of the power system.

Key words：distribution lines; composite materials; cross arm poles and towers; bearing capacity calculation
