What Is Electrical Cable-:Electrical cable is consisting of two or more wires, or conductors with their own insulation. Its wires are bonded, twisted or braided together. An electrical cable are more flexible by stranding the wires. Obviously maximum time we are used copper wires in a cable and it may be bare tin, gold, and silver. Very low amount prone are given from Tin, Gold and Silver so its oxidation is much less to copper, and makes soldering easier than to copper. What is Earth Leakage Circuit Breaker (ELCB)-: ELCB is a voltage detection device or safety device. These equipment is used in electrical installations with high earth impedance to avoid shock. These devices detect the small stray voltage of the electrical device on the metal enclosures, and obstruct the circuit by identifying a dangerous voltage. Protects humans and animals from dangerous electric shock.
Generally having two type of ELCB
(1) Voltage Operated
(1) Current Operated
Electrical cable generally four types & they are:- PVC(Polyvinyl Chloride) Cable-: PVC is asymmetric material obtained from acetylene and can be used in many ways ,and it can be done on the basis of polarization process. These is a common plastic cable insulation or jacket. Which is in the form of white powder, it is usually non-flammable and insoluble at normal temperature in a fluid, tasteless, odorless. Its temperature range is -55 ° C to 105 ° C and its have moisture and friction-resistant. In pure form it is rigid and brittle at low temperature. Therefore it is better for rubber in many environmental conditions.
