What is computer power cable?

Alternatively known as a power cable, mains cable or flex, a power cord is the primary cable that provides power to the computer, printer, monitor, and components within a computer. The image is an example of the power cord that is commonly used with computers, monitors, printers, and other peripherals.

What is inside a power cord?

The hard wired (non-detachable) power cord consists of a plug, the cordage, and a strain relief device to secure the cord to the equipment enclosure. The detachable power cord, also known as a power cord set, consists of a plug, cordage and a connector or receptacle.

Why is metal used for power cables?

All metals have some amount of resistivity to electrical currents, which is why they require a power source to push the current through. The lower the level of resistivity, the more electrical conductivity a metal has. Copper has low resistivity, and therefore is an excellent conductor.

Why are electric wires covered with plastic?

Most electrical wire is covered in a rubber or plastic coating called insulation. ... The purpose of insulation covering the metal part of an electrical wire is to prevent accidental contact with other conductors of electricity, which might result in an unintentional electric current through those other conductors.

Which is the best conductor of electricity?

Which Metal Conducts Electricity The Best?

Material IACS (International Annealed Copper Standard)
Ranking	Metal	% Conductivity*
1	Silver (Pure)	105%
2	Copper	100%
3	Gold (Pure)	70%

What are the top 5 electrical conductors?

The most effective electrical conductors are:

• Silver.
• Gold.
• Copper.
• Aluminum.
• Mercury.
• Steel.
• Iron.
• Seawater.

Is Gold the best conductor of electricity?

Gold is used as a contact metal in the electronics industry as it is a good conductor of both electricity and heat. ... Gold wire Gold is ductile: it can be drawn out into the thinnest wire.

Why is gold not used for electrical wires?

Gold is not used for making electric wires because it is too rare, and too costlier than Copper. Silver and copper are used for making wires. Copper is almost used in electric lines. ... But, gold is too costlier than these two.

Which is the bad conductor of electricity?

Materials like glass and plastic are poor electrical conductors, and are called insulators. They are used to stop electricity from flowing where it is not needed or where it can be dangerous, such as through our bodies.

Is Salt a conductor?

This is because salt water is a good conductor of electricity which makes ocean water a resource for renewable energy. Salt molecules are made of sodium ions and chlorine ions. ... These ions are what carry electricity through water with an electric current. In short, salt water can help to produce electricity.

Is good conductor of electricity?

Most metals are considered to be good conductors of electrical current. Copper is just one of the more popular materials that is used for conductors. Other materials that are sometimes used as conductors are silver, gold, and aluminum. ... Some common insulator materials are glass, plastic, rubber, air, and wood.

What is a Class 1 conductor?

Conductors of different circuits. Class 1 circuits can occupy the same cable, enclosure, or raceway without regard to whether the individual Class 1 circuits are AC or DC, provided all the Class 1 conductors are insulated for the maximum voltage of any conductor in the cable, enclosure, or raceway.

What is the largest conductor?

The larger the AWG number or wire guage, the smaller the physical size of the wire. The smallest AWG size is 40 and the largest is 0000 (4/0).

What is a class 5 conductor?

This refers to the flexibility and thermal effects i.e temperature of a conductor. Class 1: Solid conductor. Class 2: Stranded conductor intended for fixed installation. Class 5: Flexible conductor.

What are the standard cable sizes?

Standard Cable & Wire Sizes

International standard wire sizes (IEC 60228)

0. What does 12 gauge wire mean? The gauge is the size of the wire. The higher the number the smaller the wire. If your stereo is high power you might want to use 14 or 12 gauge wire for better power handling. Is 1554 a standard? conforming to IS: 1554(Part-I) and its amendments. provided on the outer sheath of all cable with marking “WBSEDCL”. armouring shall be galvanized round steel wires and its nominal diameter shall conform to clause no. 13. IS 1554 and IS 7098? Code: IS: 7098, 1554 / IEC: 60502 / BS: 6622 / BS: 7835. It could be also called inner sheath or inner jacket, which serves as a bedding under cable armoring to protect the laid up cores and as a separation sheath. Inner sheath is over laid up of cores. Is 5831 Type ST2? Type A General purpose insulation for maximum rated conductor temperature 70°C intended for cables with rated voltages U,/U up to and including 3. Is standard for FRLS cables? For 'FRLS' cables during fire, visibility maintained is at least 40% or smoke density of 60% maximum. It is measured as per IS 10810 Part 63 or ASTM D 2843. For 'LSZH' cables during fire, visibility maintained is at least 80% or smoke density of 20%. It is measured as per IS 10810 Part 63 or ASTM D 2843. What is the difference between FR and FRLS wires? FR PVC insulation has better fire retardant properties than normal PVC. FRLS PVC insulation provides better fire retardant properties then normal PVC & also emits Low Smoke, in case of fire. Is 694 a Polycab? Polycab PVC insulated Industrial Wires & Cables are manufactured as per IS 694 : 1990, in Single Core sizes from 0. Is 694 an electrical wire? These cables are designed for residential and commercial infrastructure. Ratnaflex -M FR-LSH: Flame Retardant Low Smoke Low Halogen (FR-LSH) cables are suitable for wiring in public places like schools, hospitals, theatres, etc. ... Is STI a 694? Amendment No 3, May 2006 to IS 694:1990 has been published (copy enclosed). In view of above, the STI has been revised as Doc: STI/694, 9 June 2006, (copy enclosed). ...
