An underground cable is a type of insulated conductor that carries electrical power below the earth's surface. It is well-protected from weather, accidents, and vandalism.
Solder (धातु मिश्रधातु)
Flux (फ्लक्स – साफ और चिपकाने वाला पदार्थ)
Let’s understand both in detail.
sually wires or terminals) by melting a filler metal (solder) between them. It is commonly used in electrical and electronic work to ensure a strong and low-resistance connection.
.
When two or more wires need to be connected together, we use joints in electrical conductors. A good joint ensures proper current flow, low resistance, and mechanical strength.
Conducting materials are substances that allow electric current to pass through them easily. These are used in wires, cables, circuits, terminals, and other electrical components.
In electrical work, materials are classified based on how easily they allow electric current to pass through them.
A Conductor is a material that allows electricity to pass through it easily.
Electricity is a form of energy that powers most of our tools, lights, machines, and appliances. As an electrician, it’s important to understand the basic concepts of electricity before handling electrical systems.
.
Electricians often work with wood to install panels, switchboards, or fittings. So it's important to know about basic carpenter’s tools and how to maintain them.
A thread gauge is a tool used to check the size and pitch of a screw thread. It helps identify the type of thread on a bolt, screw, or nut.
.
In sheet metal and electrical fitting work, rivets are used to permanently join two or more metal sheets or components. This method is called riveting.
