Which are the best electrical wires?

Made of pure Electrolytic Copper material with less Voltage drop with best Insulation .

silver conducts best but is rather expensive.
copper is next best.

Copper wire is the best all around wire for general wiring.

1- Platinum ,Gold
2- silver
3-pure copper
4- industrial copper
5-Tungsten carbide
6-Aluminum
Each material wire it use in different electric wiring ,depend on how fast and low resist electricity you need .In very high tech performance devices ,such as space shuttles ,high tech air plans ,the most the wiring is use gold for fst transforming the information and electricity .In lower performance devices ,such industrial or residential electricity copper is most useful metal wiring .In some electronic devices ,such as computer boards a micron plated gold is require to transfer the information as fast as possible .For creating heat in devices carbit tangestan is most useful wire type .

Dear,
Thanks, am also fine like you then dear now am using chetan make also best.

gold > silver > copper > aluminum

Wire and cable must be sized and installed correctly to pass an electrical inspection and keep electricity running safely through your home. This guide will teach you the difference between wire and cable and considerations for choosing between the two.Actually, wires are selected according to the different purpose and as per the required amount of electricity to be drawn.In construction of a house/ building house owner should focus on electric works also; which need a lot of attention while laying wiring as well as quality of wiring, specification of electric appliances and cables/wires. Due to carelessness or lack of knowledge by electrician fatal accidents may occur in later and take up more money in repair. Thus every care should be taken while doing electrical fittings. Here are given some tips on how to lay wiring.

Generally,copper cables and highly insulated wires are chosen for the household and other purposes.Electrical cables/wires are laid inside walls and RCC slab which may require dismantling if any problem/defect arises in later. Dismantling is very costly as compared to getting it rightly fixed first time.
n case of defects in electrical wires they can cause fire in house and may even take human life in some cases. So make sure you do the following to ensure good electric works.
A professional or good electrician should be hired for electric works. All electric works and installations should comply with latest Indian Electricity Acts and Rules in all respects.
All materials used in electrical fittings should be of approved and from a reputed manufacturer as per ISI specifications.
Make sure that electrician has calculated total load from various items that would be used in the house. Whether he lays wires that are capable of taking total load.
It is seen that a lot of times electricians are careless while putting right load bearing wires for a purpose and these wires get burnt at the movement when entire load is put on wires.

The most common mistake we make as engineers is inadequate definition of the problem. We want it to work BEFORE we say what does it mean to work? Ampacity, conductor design, insulation material and design, operating environment, and expected functionality, life and cost are all part of working best. A different best wire in your smart phone than best wire for the power pole.

Different wires are best for their own purpose. Almost all are made of copper.Wire size is dependent on load and current. Cost is a factor.
Wires used for headphones are what are called "tinsel" wires because they have to be super flexible but only carry very small current so they are like the width of a hair, while the supply to your meter are about as thick as a finger of solid copper strands to handle the current - over 100 Amps, and are not flexible.

Next, consider the insulation as this is application and budget dependent.

And stranded is usually "better" than solid, but not always, especially in smaller sizes
