Marine Transformers (Off-Shore Applications)
In all cases reliability is the key issue and the reason why many ship owners, operators and system designers continually specify the STS product.
Protection enclosure ranges from IP23, to IP55 (totally sealed) combined with the required cooling arrangements such as naturally air or forced air cooling systems or air/water heat exchangers.
These configurations can be optimized to align with the specified vessel system, accounting for power ratings, available installation space, and environmental protection requirements.
The marine transformers produced by our company can be classified as follows:

Drive Transformers
These are converter transformer for electric motor driven ships used in the New Age propulsion systems. Apart from the use of copper conductive, special materials are also used against corrosion under sea conditions. In addition vibration effects are important in design. The conditions of the medium and sizing should be stated by the customer. STS (Sonmez Transformer) is able to produce converter transformers for 6-12-18-24-36-48 pulse applications. Detailed information about converter transformer could be found under "Converter Transformers" topic in our website.

Internal Need Transformers
These transformers are designed to meet the internal power supply requirements of ships. They incorporate copper conductors and special materials to withstand harsh sea conditions. Additionally, careful consideration is given to vibration effects during the design process. The customer is expected to specify the conditions of the medium and sizing requirements. It is advisable to include a spare coil for optimal supply."

General Information About Production
CORE
The magnetic circuit comprises laminated cores made from M5, M4, or M3-grade steel arranged in a step-lap configuration. Losses at no-load, noise levels, and harmonic distortion values have been minimized. The core and coils are secured with stainless steel clamps to withstand mechanical stresses from short circuits.
WINDINGS
The conductive material for windings is produced from copper strips or sheets. Winding insulations consist of Nomex, enamel, or glass fiber, depending on the desired insulation class. Coils are wound in multi-layered cylindrical, helical, or disc winding shapes. Depending on the type, windings are impregnated or encapsulated in epoxy resin casting."
ASSEMBLY
Utilizing terminals compliant with DIN standards.All outputs are tin-plated, and bare conductors are not visible. Tap changing is done with removed adjustment tips on the coil. Cooling in AN transformers is achieved through natural air circulation, while AF transformers use ventilation fans. The transformer is enclosed in a housing based on the desired protection class.
CLASS CERTIFICATION
Marine Transformers produced by STS can be certified by class certification companies upon request. STS has extensive experience collaborating with various class certification entities. A few of them include:
