Transformer Corrosion, Oil Degradation & Protective Measures in the Humid Mediterranean Climate
Technical analysis of environmental challenges affecting outdoor and kiosk transformers in coastal Alanya and Antalya: high humidity, airborne sea salts, bushing flashovers, and mobile vacuum oil purification solutions.
The Mediterranean coastal belt exposes medium-voltage electrical apparatus to severe relative humidity (up to 85%), airborne marine salts, and extreme ambient heat. These factors accelerate tank oxidation, bushing tracking, and dielectric oil degradation.
Key Protective Measures:
- Hermetically sealed tank construction preventing atmospheric ingress
- C5-M ISO 12944 marine-grade epoxy and polyurethane tank coatings
- Hydrophobic RTV silicone coatings on porcelain bushings
- On-site mobile vacuum degasification restoring oil breakdown to >65 kV
