Overhead line fittings are components that are used to connect and support conductors and insulators in overhead power transmission and distribution systems. They are designed to withstand the mechanical and electrical stresses of the system and provide a reliable and durable means of transmitting electrical power.
There are various types of overhead line fittings, each with a specific function and application. Some of the commonly used fittings include:
1. Suspension clamps: These are used to hang conductors from a pole or tower.
2. Tension clamps: These are used to maintain the tension in conductors and keep them in place.
3. Dead-end clamps: These are used to terminate a conductor at the end of a line.
4. Splices: These are used to join two conductors together.
5. Insulators: These are used to support conductors and provide electrical insulation.
The working principle of overhead line fittings is based on the mechanical and electrical properties of the materials used in their construction. These fittings are designed to withstand the mechanical stresses caused by the weight of the conductors and the wind load. They are also designed to provide electrical insulation and prevent electrical discharge.
The choice of fitting depends on the application and the type of conductor being used. For example, high voltage conductors require fittings that can withstand higher electrical and mechanical stresses compared to low voltage conductors.
In conclusion, overhead line fittings are an essential part of any electrical transmission and distribution system. They provide a reliable and durable means of transmitting electrical power and ensuring the safety of the system. Understanding the different types of fittings and their working principles is crucial in designing and maintaining an effective overhead power transmission and distribution system.
