Comprehensive Arrester Solutions for Southeast Asia
I. Key Challenges in Southeast Asian Power Systems
Extreme Climate Challenges
Highest Global Lightning Density: Over 160 thunderstorm days annually in regions like Indonesia and Malaysia.
Heavy Rainfall + Salt Fog Corrosion: Accelerated equipment aging from salt erosion in coastal areas.
Persistent High Temperature & Humidity: Accelerated degradation of sealing materials in environments ≥35°C and ≥80% RH.
Grid Vulnerabilities
Aged Assets: Over 40% of transmission/distribution equipment is obsolete (e.g., parts of Philippines and Vietnam).
Low Automation Coverage: Distribution network automation coverage <15%, resulting in significant fault response delays.
Vegetation-Related Faults: Mountainous/rainforest lines prone to lightning-induced flashovers from tree falls.
