Electrical cross arm is an engineered piece of composite equipment used in pole line technology to support power lines and other electric equipment. It is also known as telephone pole cross arm, light pole cross arm or power pole cross arms.
What is the main purpose of cross arm?
The function of the steel cross arm is to support distribution transformers, fuses, isolating links, and other line equipment. Steel cross arms of different configurations are used on overhead lines, transmission towers, transmission lines, wood poles, utility poles, power poles, and light poles.
What is the main purpose of cross are used in electric poles?
In light poles, the electrical cross arm is used to provide support to street light power lines. Along with distribution and transmission lines, the electrical cross arm used to support and anchor conductors. It holds the cable and the insulator to the main body usually the tower.
What is an electrical arm?
Circuit breakers equipped with Eaton's Arcflash Reduction Maintenance System TM (ARMS) will extinguish an arc almost instantaneously. This greatly reduces arc flash energy and the risk of injury. In the event of an arc fault, this system ensures an accelerated shutdown in comparison to a standard short circuit release.
What are wood cross arms made of?
Wood crossarms are one of the most important components at the top of electric transmission and distribution poles. Produced from Douglas Fir and Southern Pine timber, wood crossarms must meet exacting standards for strength and durability in use.
What are cross arms treated with?
- CCA.
- Penta.
- CuNap- Copper Napthenate.
What are cross arm pin insulators also called?
It is also known as telephone pole cross arm, light pole cross arm or power pole cross arms.
What is steel cross arm?
The function of the steel cross arm is to support distribution transformers, fuses, isolating links, and other line equipment. Steel cross arms of different configurations are used on overhead lines, transmission towers, transmission lines, wood poles, utility poles, power poles, and light poles.
What is a cross arm on a power pole?
The cross arm of the power transmission line is a special steel structure designed to hold the power line wires on the pole. Cross arm is installed on poles of both round and square cross-section with fastening by a clamp/pole strap. They are used to fix securely the wires of the overhead line to the pole.
