copper wire

Copper wire is the preferred conductor for many electrical applications because of the high conductivity of copper, which contributes to its optimal performance. Suitable for a wide range of applications due to its versatility, copper requires less insulation and can be stretched more effectively than other metals. Though copper is an excellent conductor of electricity, there are several different types of copper conductors to choose from, and it is important to understand the variances when selecting wire for your application.

copper wire advantages

Electrical and thermal conductivity: The high electrical and thermal conductivity of copper makes it stand out from other metals. This makes copper wiring the go-to option for applications such as transformers, switch gears, and many other electrical applications.
Ductility and malleability: Copper wires are highly ductile and malleable and can be formed and stretched easily without breaking or affecting their electrical properties.
Good tensile strength: Copper wiring has a high tensile strength which prevents breakage, stretching, and other physical damage.
Creep resistance: Creep is the deformation of metal conductors that occurs when they expand and contract under cyclic loads. Copper has higher creep resistance compared to other metals like aluminum.
Corrosion resistance: Copper wires generally have good corrosion resistance properties and keep good performance when affected by moisture, humidity, industrial pollution, and other environments.
