What is an Incandescent Lamp? Definition, Construction, Working, Advantages, Disadvantages & Applications

An incandescent lamp generates light when an electric current passes through a filament, heating it to incandescence. The filament is typically made of tungsten and enclosed in a glass bulb filled with an inert gas (like argon or nitrogen) to prevent oxidation.

What is Discharge Lamp? Construction, Working, Types, Advantages, Disadvantages & Applications

A discharge lamp is a type of light source that generates light by passing an electric current through a gas or a mixture of gases. When the gas is energized by the electric current, it produces visible or ultraviolet light through a process called gas discharge.

What is Shackle Insulator? Construction, Working, Types, Advantages, Disadvantages & Applications

A Shackle Insulator, also known as a spool insulator, is a type of low-voltage electrical insulator commonly used in distribution networks to support and insulate conductors. Shackle insulators are compact, durable, and designed for horizontal or vertical mounting on poles or walls. They are widely utilized for low voltage (up to 33 kV) applications, particularly

What is Pin Insulator? Construction, Working, Types, Advantages, Disadvantages & Applications

A Pin Insulator is a type of electrical insulator mounted directly on a pole or tower to support conductors and insulate them from the supporting structure. It is one of the oldest and most commonly used insulators for low to medium voltage transmission lines. Pin insulators are typically made of porcelain, glass, or composite polymer

What is Strain Insulator? Construction, Working, Types, Advantages, Disadvantages & Applications

A strain insulator is a type of electrical insulator used to withstand mechanical tension in overhead transmission and distribution lines. These insulators are specifically designed to provide both mechanical strength and electrical insulation in situations where conductors are under significant tension, such as at sharp bends, dead-end poles, or long spans.

What is Suspension Insulator? Construction, Working, Types, Advantages, Disadvantages & Applications

A suspension insulator is a type of electrical insulator used in overhead power transmission and distribution lines. Its primary function is to insulate the conductor (carrying high voltage) from the supporting structure (e.g., towers or poles) and maintain the mechanical strength required to sustain the conductor.

What is Underground Cable? Construction, Types, Advantages, Disadvantages & Applications

An underground cable is a type of electrical cable used for transmitting and distributing electricity beneath the ground’s surface. Unlike overhead transmission lines, these cables are concealed, offering better protection from external environmental factors, enhanced safety, and improved aesthetic appeal. Underground cables are widely used in urban areas, industrial installations, and specialized applications like submarine

What is Oil Circuit Breaker? Definition, Construction, Working, Diagram, Types & Applications

An Oil Circuit Breaker (OCB) is a type of circuit breaker that uses insulating oil as both an arc-quenching medium and an insulating medium. The oil is vaporized during the interruption process, producing gases that effectively cool and extinguish the arc formed when contacts separate under load or fault conditions. It is widely used in
