详细报告
## Background
Connecting remote wind farms to the grid requires long transmission lines. Traditional steel-cored aluminum (ACSR) is heavy and prone to theft. Copper is too expensive and heavy.
## The Challenge
A grounding and transmission solution that:
1. Is theft-deterrent (unlike pure copper).
2. Has high mechanical strength for long spans.
3. Provides adequate fault current capacity.
## The Solution
Raytron Copper Clad Steel (CCS) strand.
- **Strength**: Steel core provides exceptional tensile strength.
- **Conductivity**: Copper cladding handles high-frequency AC and transient fault currents (skin effect).
- **Theft**: Difficult to recycle/separate compared to pure copper, discouraging theft.
## Results
- **infrastructure**: Reduced tower count by 10% due to longer spans.
- **Safety**: Maintained grounding safety levels during fault conditions.
- **Reliability**: Zero theft incidents in the first 2 years.
