Product Detail

Distribution transformer products are manufactured in self-contained synchronous line, with advanced equipment and technology, imported from developed nations. Production process was managed by ISO 9001-2008 International Quality Management System. All of products test in testing room of transformer. The distribution transformer range to 10.000 kVA, voltage up to 35kV, designed and manufactured in accordance with the IEC 76 standard. Others capacity, voltage, vector group will manufacture on customer demand.
