An electrical cross arm is a strong and efficient pole hardware fittings that are used for supporting conductors in a power transmission line. You can also call it as light pole cross arm, telephone pole cross arms or crossarms.
Our electrical cross arm is made of hot deep galvanized steel. This material is strong to withstand any physical forces that act against eat. The galvanization protects the steel material from the effects of rust, corrosion, and abrasion.
Steel is the right choice of material for the electrical cross arm due to its tensile strength. It can sustain the mechanical forces which may threaten its stability.
The electrical cross arm comes in five different configurations. These are the Power pole cross arm, Line-cross arms, Telephone pole cross arms, and Side arms. Each configuration is specifically designed to work well in its application. So you should be aware of the configuration that will work for you.
Shape and Design
Although the electrical cross arm comes in different configurations, they tend to have a similar shape and design. The most common design is the straight bar. The design of this powerline fitting is simple and easy to install.
Another design is the V-shaped cross arm though it is not very popular.
