Transformers - Electrical, Lighting and Power
Marine transformers provide electrical isolation, voltage transformation, and power distribution for shipboard lighting, control, instrumentation, and auxiliary systems. They are available as dry-type, cast-resin, or oil-immersed units, with construction selected for marine environmental and classification requirements.
ProShipWorks provides end-to-end support to source and supply Transformers for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | IEC 60076 applies to power transformers; IEC 60092-303 covers electrical equipment and transformers for ships. IEC 60092-504 may apply to special features. Final certification depends on transformer design, installation, vessel type, and project requirements. |
|---|---|
| Class Approval | Marine installations may require approval or type approval from DNV, ABS, Lloyd's Register, Bureau Veritas, or ClassNK. Acceptance is subject to the selected design, ratings, environmental conditions, and vessel rules. |
Installation, Maintenance & Safety Information
| Installation Notes | Verify voltage ratio, frequency, kVA rating, impedance, phase configuration, earthing arrangement, enclosure protection, and classification requirements before installation. Install on a rigid foundation with adequate ventilation and clearance. Follow the manufacturer connection diagram and torque values. |
|---|---|
| Maintenance Tips | Inspect terminals, cable connections, enclosure condition, ventilation openings, and signs of overheating or moisture. Check insulation resistance and protective devices at planned intervals. For cast-resin units, keep cooling surfaces clean and dry. Perform thermal scanning where applicable. |
| Safety Notes | Isolate, lock out, and verify absence of voltage before work. Transformers may retain hazardous voltage and stored energy. Use appropriate arc-flash, electrical, and confined-space precautions. Do not exceed rated voltage, load, temperature, or short-circuit withstand limits. |
