Electric poles are structural elements used to support overhead power lines and various utility cables. They are essential for the distribution and transmission of electricity. The type of pole selected depends on factors such as load requirements, environmental conditions, and cost considerations. Below are the main types of electric poles: 1. Wooden Poles– 2. Concrete … Read more

A Strain or tension-type insulator is a type of electrical insulator designed to withstand mechanical tension or stress in addition to providing electrical insulation. These insulators are used in power transmission and distribution lines where conductors (wires or cables) need to be supported while being kept electrically isolated from supporting structures, like poles or towers. … Read more
A suspension type insulator is a type of electrical insulator used in high-voltage transmission and distribution systems. It is designed to suspend the overhead conductor or power line and electrically isolate it from the supporting structures, such as towers or poles. This ensures that electrical energy is transmitted safely without leaking to the ground or … Read more
The overhead lines conductors Pin type insulator should be supported on the poles or towers in such a way that currents from conductors do not flow to earth through supports. The insulators provide necessary insulation between line conductors and supports and thus prevent any leakage current from conductors to earth. Properties of Good Insulators- ❑High … Read more
bus bar in electrical is defined as a conductor or a group of conductor used for collecting electric power from the incoming feeders and distributes them to the outgoing feeders. The electrical bus bar is available in rectangular, cross-sectional, round and many other shapes. The rectangular bus bar is mostly used in the power system. … Read more
