South Africa Regional Dead Tank SF6 Circuit Breaker Solution Report
Ⅰ. Project Background
As the first African country adopting dead tank SF6 circuit breaker technology, South Africa's grid system faces these challenges:
- Aging Dead Tank SF6 Circuit Breakers: Existing high-voltage circuit breakers exhibit severe aging, particularly legacy dead tank SF6 circuit breakers with increased failure rates.
- Dead Tank SF6 Circuit Breaker Limitations: In high-altitude regions (>2,000m), conventional dead tank SF6 circuit breakers experience insulation degradation from low-temperature liquefaction.
- Corrosion Vulnerability: Industrial pollutants accelerate corrosion on dead tank SF6 circuit breaker components like bushings.
- Dead Tank SF6 Circuit Breaker Maintenance: Frequent outages of older models elevate maintenance costs by 38%.
II. Solution
