Who is Cable? , part | type

One Electricity A cable is an assembly of one or more wires, side-by-side, or bundles, that are used to carry electric current. A cable assembly is the structure of one or more electrical cables and their associated connectors.

What is cable? , What is the cable?

a such dielectric casing wire, in which one or more wires are bent. Cable It is called Thickness of insulation level on cable conductor Voltage depends on.


The number of different insulations in the entire conductor covered by one insulation is called a cable of as many cores. In an insulating cable, the erosive current flows radially along the core and the useful current flows radially from the core to the cover.

Cable parts | Cable ke bhaag

Its parts are as follows-

  1. Insulation- This is part of the cable. any Driver to insulate Vulcanized Rubber, Paper, Varnish, Fabric, Plastic Fabric Tape Petroleum jelly is used between the layers. Saturated insulating paper is used more.
  2. Cable Core- this piece aluminum either copper The key is made by wrapping one or more wires. This is the central part of the cable. The number of wires to be wrapped in the cable is placed in such a way that it forms a roundabout of the elongated section.
  3. Metallic Sheath- First the insulation is done over the conductor, then over the insulation aluminum or lead A thin layer is applied. This layer does not allow the moisture of the external environment to pass through to the insulation. In this, glass is used as the metal and sometimes aluminum sheath is used.
  4. Bedding- A layer of paper is mounted or plated over the metallic sheath. Bedding protects the metallic sheath.
  5. Armouring- through the cable Mechanical Power Is given. This steel tape is in the form of wires.
  6. Serving – A layer like bedding is applied over the armoring, which is serving it is said.

Cable Types | Cable ke Prakar

  1. VIR cable- its full form Vulcanized Indian Rubber There is cable. It is prepared by weaving cotton yarn and applying bitumen coating. use of this type of cable capping-casing, conduit pipe and temporary Electricity wiring is done.
  2. PVC cable- This cable is produced by plating PVC over a copper or aluminum bare wire. It protects the cable from the effects of the environment and from external influences.
  3. CTS cable- This is called Tough Rubber Shield Cable. This type of cable is used for electrical wiring in damp places.
  4. Tropodure Cable- It is prepared by coating a ‘thermoplastic compound’ over PVC cable. It is used in railway signal and power equipment.
  5. lead sheathed cable It is mechanically sound. It is produced by plating a vulcanized Indian rubber cover over a tin coated copper wire and a lead metal protective cover over it. They are used in the wiring of chemical industries and other machines.
  6. weather-proof cable This VIR It’s like a cable. But instead of coating the bituminous substance in it, it is subjected to environmental change temperatures ( sun, cold and rain etc.) immersed in a tolerant liquid ‘Weather-proof’ is done. use this home and industrial in open spaces.
  7. Armored Cable – It is made by plating a dielectric layer of polyethylene over a single-stranded copper wire. It is used for power supply in the form of underground cable.
  8. Flexible Cable- This cable made by collecting many fine wires as a group by applying a dielectric cover is called flexible cable.

Classification of cables on the basis of voltage grade. Voltage grade ke aadhaar par cable ka vargeekaran

  1. low voltage cable The cable that we use to light the lights and run the fan in the house is Lower voltage of happens. This 250 volts Can carry voltage up to This PVC, CTS, VIR, Weather-proof & Flexible There are.
  2. medium voltage cable 650 volts voltages designed for industrial and household power loads up to medium voltage called cables. This CTS, PVC, VIR, Lead Sheathed, Weather-Proof, Tropodure & Flexible There are.
  3. High Voltage Cable – 22,000 Volts cables used in power distribution systems, high voltage cable are called. This Armored Cable & Stranded There are types of bare wire.
  4. ultra high voltage cable 22,000 volts cables used at higher voltages, very high voltage are called. It is a stranded type of bare wire and it copper are made of.

Cable Qna-

How is the cable made?

To make it, one or more wires are prepared by joining and twisting.

What is the cable used for?

What is a cable example?

The definition of cable means a rope-like bunch of wires used to connect two things. A cord connecting your phone to a wall socket is an example of a cable. The connection between your computer and your Internet service provider is an example of a cable.

What is cable structure?

Cable structure, form of long span structure that is subject to tension and uses suspension cables for support. The cable-stayed roof is supported from above by steel cables that run down from masts that rise above roof level.

How do cables work?

Electrical cables work by providing a low resistance path for current to flow. The simplest electrical cable may just be a metal conductor – these cables are used as overhead line wires constructed without any insulating material around the conductor other than the air around the conductor.
