6.6 kV Cast Resin Dry-Type Transformer

Overview: A 6.6 kV cast resin dry-type transformer is a possible indoor step-down solution for industrial medium-voltage systems. The winding insulation and air-cooling arrangement should be matched to the room and operating duty.

Where this configuration is considered

Facilities with a 6.6 kV bus may place dry-type equipment near production loads or electrical rooms. Harmonic-producing equipment, motor starts and limited ventilation need specific review.

Information to define before quotation

State kVA, HV/LV ratio, frequency, impedance, load cycle, harmonics, ambient temperature, altitude and room airflow. Specify enclosure, temperature monitoring, sound and documentation needs.

International standards to review

Reference standards may include IEC 60076-1:2011, IEC 60076-11:2018. The applicable editions, clauses, conformity evidence and test scope must be agreed for the final design and destination market. This page does not claim certification or guaranteed compliance for an unspecified product.

A useful question for the technical brief

Are there frequent motor starts or converter loads on the secondary bus?
