Why is White Powder Used in Electrical Cables?

We always see a white powder inside an electrical cable. It is wondering mostly why we use this powder in the cables.

In this article, we will discuss about the electrical drawings and types of electrical diagrams mostly used in the industrial sectors.

In this article, you will learn why is IGBT used in VFD drive. IGBT means Insulated Gate Bipolar Transistor.

A current Transformer is a device that is surrounded by a live phase wire in a three-phase system, to measure the current flowing through it.

The Buchholz relay is used to detect internal faults in an oil-filled transformer and it works on the theory of gas detection.

In this post, we will learn the effect of the long distance cables between VFD and motor, and why it must be avoided.

A transformer bushing is an electrical insulator that allows the safe passage of electrical conductor current.

An auto changeover switch is used to automatically switch the electrical power between primary and secondary sources.

In this post, we will learn the types of conductors used in overhead cables. An electrical wire has two parts – conductor and insulator.

In this post, we will learn about the most common types of industrial circuit breakers and their principle of operation.
