Background

An electric power line refers to a line used to transmit electric energy between a power plant, a substation, and an electric power consumer. It is an important component of a power supply system and is responsible for the task of delivering and distributing electrical energy. The power circuit is a conductor loop which connects the power substation and the distribution substation with each electric energy user or electric equipment and transmits and distributes electric energy from the power supply end (the power substation and the distribution substation) to the load end (the electric energy users or the electric equipment). The power line is divided into high voltage line and low voltage line according to voltage. The high-voltage line refers to a power line with a voltage of 1kV or more, and the low-voltage line refers to a power line with a voltage of 1kV or less. Some power lines of 1kV to 10kV or 35kV are referred to as medium-voltage lines, power lines of 35kV or more to 110kV or 220kV are referred to as high-voltage lines, and power lines of 220kV or more are referred to as extra-high-voltage lines. Basic requirements of the power line: safe and reliable power supply, convenient operation, flexible operation, economy and favorable development. The cross arm is an important component in a tower and is used for installing insulators and hardware fittings so as to support a conducting wire and a lightning conductor and keep a certain safety distance according to regulations.
