15 Important Electrical Safety Procedure and Precaution

In my last post I talked about Current and Voltage effects on human body and now I am going to tell you what Electrical Safety Procedure and Precaution you should maintain when you are at electrical work? 15 Electrical Safety Procedure and Precaution: Don’t depend only on switches; pull the plug from the socket. As an additional precaution, fuse must also be pulled where provided. Use a maintenance friendly safety panel board. Use cartridge fuse in panels. Never use re-writable Read More …

Current and Voltage Effects on Human Body

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

Different Types of Cable Insulators

Electrical Cable can come with insulation or not. There are some type of over head transmission and distribution cable don’t have insulation on it because it stay up from ground level. But if a cable is passing through ground level and human and animal is 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 equipments in power transmission and distributions Read More …

Aluminium Conductor Steel Rein-Forced (ACSR)

In my last post I talked about the various types of electrical cable conductor. Now I will discuss about (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 it surrounded by a numbers 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 Conductor its not an Electrical Cable. In market you will find different types of electrical cable with few types of conductor. In this post we will learn Various Types of Electrical Cable Conductor. What is Electrical Conductor: The material, which resist a few portion of current flow known as conducting material. But when, it used in bare strand or solid material then its called conductor. Mainly conducting material used for transmission or the distribution of electric power. For this reason Read More …
