# Power Transformer — Up to 345 kV, Up to 500 MVA

## Product Overview

Daelim power transformers are engineered for utility, substation and industrial power projects, covering ratings up to **345 kV** maximum voltage and **500 MVA** maximum capacity. The design targets low partial discharge, low loss, low noise, high reliability and strong protection against abrupt short-circuit events, making it suitable for demanding transmission and distribution duties.

Each unit can be configured with cover-mounted or sidewall-mounted bushings for connection to primary and/or secondary switchgear, and constructed with a wide range of core steels and winding conductors to balance efficiency against cost. Flexible core/coil and tank construction allows dimensional requirements to be met.

## Key Features

- Low local discharge, low loss, low noise and high reliability
- Strong protection against abrupt short circuit
- Available with cover-mounted or sidewall-mounted bushings for connections to primary and/or secondary switchgear
- Constructed with a wide range of core steels and winding conductors to optimize efficiency versus cost
- Flexible core/coil and tank construction enables dimensional requirements to be met
- All units meet applicable ANSI, IEEE and NEMA standards, as well as IEC and CSA specifications
- KAMA certificates for Model SFZ11-50000/132

## Applications

Daelim power transformers are suited to utility transmission and distribution substations, industrial power systems and overseas tender projects, including South America.
