Document description

Engineered for offshore/onshore oil & gas hazardous areas, this transformer features critical vibration endurance, flameproof natural/synthetic ester oil options, streamlined compact dimensions, and high-IP protection boxes; it strictly adheres to IEC 60076 (Power Transformers) and IEC 60079 (Explosive Atmospheres) standards, alongside ATEX Zone 1 & 2 and DNV/BV marine certifications.

Frequently asked questions

Why are oil-filled transformers preferred over dry-type transformers in offshore oil & gas applications?

Compared to dry-type units, oil-filled transformers offer vastly superior insulation endurance and mechanical protection against salt-laden moisture, corrosive pollutants, and structural vibrations.

Can the transformer be filled with flameproof, biodegradable natural or synthetic ester liquids?

Yes, flameproof and biodegradable natural or synthetic oils are available on demand to significantly reduce fire hazards and environmental pollution risks in sensitive offshore waters.
