What Is 21% Conductivity Copper-Clad Steel Strand?
21% conductivity copper-clad steel strand is a stranded bimetallic conductor consisting of a steel core with a continuous copper cladding layer. The steel provides mechanical strength, while the copper layer provides electrical conductivity and helps protect the steel core.
The term 21% IACS refers to a nominal electrical conductivity level of approximately 21% of the conductivity reference represented by the International Annealed Copper Standard. The appropriate conductivity and conductor construction should always be selected according to the project's electrical and mechanical requirements.
Why Choose 21% IACS Copper-Clad Steel Strand?
CCS strand combines the advantages of two materials to meet electrical and mechanical requirements in demanding infrastructure projects.
Strength + Conductivity
The steel core provides mechanical strength while the copper cladding provides the conductive surface.
Efficient Material Use
CCS uses a steel core instead of making the entire conductor from copper, which can be advantageous for large infrastructure projects.
Mechanical Durability
The steel core helps provide tensile strength for applications where mechanical performance is important.
Multiple Applications
CCS strand can be considered for grounding, lightning protection, railway earthing, utility infrastructure and other applications.
Applications of 21% Conductivity CCS Strand
Grounding Systems
Used in grounding systems where electrical performance and mechanical strength are both important.
Lightning Protection
Can be considered for conductive paths in lightning protection and grounding systems.
Railway Earthing
Suitable for evaluation in railway earthing systems according to project requirements.
Cathodic Protection
Can be used in selected cathodic protection applications subject to system design.
What Should Buyers Check When Purchasing CCS Strand?
A professional CCS strand quotation should include more than the price per kilogram. Buyers should confirm the following technical and commercial requirements before production.
| Item | What Buyers Should Confirm |
|---|---|
| Conductivity | 21% IACS or other required conductivity grade |
| Conductor Size | Overall diameter or required cross-sectional specification |
| Strand Construction | Number of wires, wire diameter and stranding configuration |
| Mechanical Performance | Tensile strength and other project-specific requirements |
| Testing | Electrical, mechanical, dimensional and surface inspection requirements |
| Standard | ASTM, IEC, EN, GB or project-specific specification |
21% vs. 30% vs. 40% vs. 70% Conductivity CCS
Higher conductivity is not automatically the best choice. The correct CCS grade depends on electrical requirements, conductor dimensions, mechanical performance and the applicable project standard.
Suitable for applications where conductivity, mechanical strength and cost efficiency need to be balanced.
Provides a higher conductivity level when required by the electrical design.
Considered where a higher electrical conductivity specification is required.
Designed for applications requiring significantly higher electrical conductivity.

Frequently Asked Questions About 21% CCS Strand
What does 21% IACS mean?
21% IACS indicates a nominal electrical conductivity level of approximately 21% of the conductivity reference represented by the International Annealed Copper Standard.
Is 21% conductivity CCS suitable for grounding?
Copper-clad steel products are used in grounding applications. However, the correct conductivity, diameter and construction must be selected according to the grounding design and applicable standards.
What is the difference between CCS wire and CCS strand?
CCS wire is an individual copper-clad steel element. CCS strand consists of multiple CCS wires stranded together to form a larger conductor.
Is 21% IACS the highest conductivity CCS grade?
No. Copper-clad steel products are available in different conductivity grades. The appropriate grade should be selected based on the electrical and mechanical requirements of the application.
What information should I provide when requesting a CCS strand quotation?
Provide the required conductivity, conductor size, strand construction, application, quantity, applicable standard, destination and required delivery date whenever possible.
