copper as conductor for cable used as
Answers
Answer:
Copper is commonly used for building wire because of its conductivity, strength, and reliability. Over the life of a building wire system, copper can also be the most economical conductor. Copper used in building wire has a conductivity rating of 100% IACS or better.
Explanation:
Copper has high electrical conductivity and low resistance. Other than copper; gold can be used for wires but gold is highly expensive. Next possible candidate for wires is aluminum. It has good electrical properties but not good as copper.
Copper resistivity and conductivity : 1,72×10-8 Ω mm2/m , 58,14 Ω m-1
Aluminum resistivity and conductivity : 2.82×10-8 Ω mm2/m , 35,46 Ω m-1
As you can see from upside copper is better than aluminum BUT copper cost 4 times more than aluminum. Furthermore today in most areas aluminum wire usage increase.
Answer:
Copper as a conductor in electrical cable is used in annealed form.
Explanation :
- A cable is a single, insulated conductor that is at least two conductors long.
- A power cable is an electrical cable that is made up of one or more electrical conductors and is typically sheathed to keep it all together.
- Power cable is mostly utilised in annealed form for power distribution and transmission applications.
- The last step in the delivery of electrical power is an electrical distribution system, which transports electricity from the transmission system to the individual users.
- Distribution substations attach to the transmission system and employ step down transformers to reduce the transmission voltage to medium voltage.
- For lines under 10 km in length, power distribution by cable is usually used.
- Cable was frequently used to describe a particular type of nautical line.
- Although small power cables may employ solid conductors, power cables typically use stranded copper or aluminium conductors.
