Koprex states that its copper strip and busbar offerings can be supplied in soft, half-hard, and hard conditions.

Copper Strip Sizes and Specifications

One of the most important considerations when sourcing copper strips is dimensional accuracy.

Copper strip sizes can vary significantly according to the application.

Buyers should specify:

There is no universal size that is suitable for every application.

For example, a copper strip used in a compact electrical assembly may require very different dimensions from one used in a large power distribution system.

Koprex currently lists a copper strip/busbar range with a minimum cross-sectional area of 10 mm², maximum cross-sectional area of 2,000 mm², and minimum width of 2 mm, while noting that specifications can vary according to the product requirement. This is why buyers should provide a detailed drawing or technical specification wherever possible.

Copper Strip Grades: Why They Matter

The copper grade influences the material's properties and suitability for different applications.

Depending on the product and manufacturer, copper strip grades can include different commercially pure copper and specialised copper grades.

When evaluating copper strip specifications, buyers should look at:

The correct grade should be selected based on the application's actual requirements rather than simply choosing the highest-purity material available.

Major Applications of Copper Strips

Copper strips are used in many industries because of their electrical and thermal properties.

Electrical Panels and Switchgear

Copper strips can be used as conductors and connection components within electrical distribution systems.

They may form part of:

Their high conductivity can support efficient power transmission within the equipment.

Copper Busbar Applications

Copper busbar strips are widely associated with electrical power distribution.

A busbar provides a low-impedance path for distributing electrical power between different circuits or equipment.

Copper is well suited for busbar applications because of its combination of conductivity, thermal performance, and machinability.

Koprex identifies copper strips and busbars as products used for electrical conductivity and heat dissipation and offers different hardness conditions for application-specific requirements.

Transformer Applications

Copper is extensively used in electrical transformers because of its conductivity and ability to carry current efficiently.

Depending on the transformer design, copper strip or related copper conductors may be used in winding and connection applications.
