Grounding System Key Metrics Comparison

Metric	CCS	Pure Copper	Note
Conductivity	20-40% IACS	100% IACS	Grounding focuses on fault current capacity
Tensile Strength	850-1300 MPa	200-400 MPa	CCS 3-4x stronger
Grounding Life	30+ years	15-20 years	CCS longer lifespan
Theft Risk	Low	High	Steel core no scrap value
Thermal Stability	Excellent	Good	Low thermal expansion

Why CCS is Recommended for Grounding Systems?

💪

Ultra-High Strength

Tensile strength up to 1300MPa, 3-4x that of pure copper. Ideal for long-span overhead ground wires, reducing support towers.

⏱️

Extended Lifespan

Grounding lifespan up to 30+ years, 1.5-2x that of pure copper. Reduces maintenance and replacement costs.

🔒

Theft Deterrent

Steel core has no scrap value, effectively preventing grounding wire theft. Protects critical infrastructure.

🌡️

Thermal Stability

Low thermal expansion coefficient, dimensionally stable during temperature changes. Suitable for extreme climates.

💰

Cost Effectiveness

Material cost 20-30% lower than pure copper, plus longer life and lower maintenance, lower total cost of ownership.

📜

Standards Compliance

Compliant with IEEE 80, ASTM B227 international standards. Widely used in power, railway, telecom industries.
