Oil-Filled Distribution Transformers

Oil-Immersed Distribution Transformers
Oil-immersed distribution transformers are used to reduce medium voltage (3.3 – 36 kV) to low voltage levels (≤ 1000 V).

Medium Power Transformers
These transformers are widely used in urban distribution networks, industrial installations, and power plants.

Distribution and medium power transformers can be manufactured in single-phase or three-phase versions. Mineral oil, either inhibited or uninhibited, is used as the cooling medium. Upon request, non-flammable fluids can also be used.

According to customer requirements, they can be supplied with:

• Cooling systems ONAN, ONAF, ODAF, OFAF, OWAF
• With conservator (oil expansion tank) or hermetically sealed
• With off-load or on-load tap changer
• With cable box or protection box
• With porcelain bushings or plug-in type resin terminals

Transformers are manufactured according to customer specifications, contractual requirements, or technical standards such as TS 267, IEC 60076-1, BS 171, DIN, ANSI, ENEL, ENDOSA, CSA, ensuring high quality, reliability, and long service life.
