Electricity transmission is the procedure to deliver generated electricity mainly over long distances to the grids usually situated in populated areas. There are some vital components of electricity transmission. Electrical transmission systems combine distribution systems, power plants, substations etc. Read this blog to know about important components of electricity transmission systems.
What is electricity transmission?
Electricity transmission lines manage bulk transportation of the electricity from one point to another. The main part of this entire process of transmission consists of transformers that increase voltage levels for making long-distance electricity transmission feasible.
What are vital components of electricity transmission?
Several important components of electricity transmission lines play an integral role in successfully conveying power from the plants to utilities. Have a look:
a) Towers
Transmission towers are the visible vital component of the huge power transmission system. They keep high voltage conductors isolated from their surroundings & even from each other. Higher voltages lines always need greater separation. These towers are also known as electricity pylons – a tall structure that supports overhead power lines. In the electricity power grids, transmission towers are used to convey HV transmission lines from generating stations to substations. The design consideration for the towers must prevent faults. Those considerations are conductor spacing, height and length of insulator needed for mounting the conductor.
b) Conductors
Several conductor compositions in recent years can meet varied particular requirements. Previously copper material was used due to its great electrical conductor. Conductors are the main components that carry current from one point to the other. Usually, the single circuit poles consist of three conductors. Few poles are specially designed for carrying two circuits and these poles consist of six-line conductors.
c) Substations
The voltage needs economical electricity transmission of electric power exceeding voltage apt for distribution to the users. The main purpose of substations is to – lower the high voltage electricity from the transmission system into much lower voltage electricity. What is the reason? It is needed so that electricity can be supplied easily to houses and business areas via LV distribution lines. Transformers are devices to reduce voltages before getting to the distribution system. These transformers are situated at the substations.
d) Insulators
Transmission line insulators are made up of porcelain. The main aim of these insulators is – to insulate the conductors from the poles and support them.
e) Power line markers
The power line markers make transmission lines visible to the drone operators, pilots and other operating machines in the surrounding areas.
f) Vibration damper
Vibration dampers usually are installed on the transmission lines for controlling the vibrations of the overhead lines. The vibration dampers have bell-shaped metallic weights fixed to metal rods.
Electricity is conveyed to the utility consumers via complex networks, Electricity gets generated at the power plants and transferred through a system. The electricity transmission system is a vital process that involves the bulk movement of electricity from the power plants to electrical substations. For maintaining a proper electricity transmission, vital components are there. You can reach out to reliable suppliers of electricity transmission solutions.
