Current and Voltage Effects on Human Body

In my last post about Electrical safety, I talked about the Electrical hazard and the reason behind it. Now I will talk about the Current and Voltage Effect on Human Body. Let’s start with the human body. Human skin resistance varied from 400 ohms for wet skin to 500000 ohms for dry skin. That’s means when you are wet then your body skin resistance will be 400 ohms and when your body skin is dry then your body resistance will Read More …

Different Types of Cable Insulators

Electrical Cable can come with insulation or not. There is some type of overhead transmission and distribution cable don’t have insulation on it because it stays up from ground level. But if a cable is passing through ground level and human and animal are crossing nearby then there is a big possibility that anyone can get Electrical Shock if the cable is not having insulation. Like cable insulation, a cable insulator is also important equipment in power transmission and distributions system. Read More …

Aluminium Conductor Steel Rein-Forced (ACSR)

In my last post, I talked about the various types of the electrical cable conductor. Now I will discuss (ACSR) Aluminium Conductor Steel Rein-Forced. So, let’s go. Aluminium Conductor Steel Rein-Forced: (ACSR) or Aluminium Conductor Steel Rein-Forced consist of a core of galvanized steel strand and its surrounded by a number of Aluminium strands. Normally the steel conductors are used for galvanized in order to prevent any kind of rusting and electrolytic corrosion. The cross section of the two metals Read More …

Various Types of Electrical Cable Conductor

Without a Conductor, it’s not an Electrical Cable. In the market, you will find different types of electrical cable with very few types of conductors. In this post, we will learn Various Types of Electrical Cable Conductor. What is Electrical Conductor: The material, which resists a few portions of current flow known as conducting material. But when it used in a bare strand or solid material then its called conductor. Mainly conducting material used for transmission or the distribution of electric Read More …
