The BRUSH range of single compartment units with high-speed resistor transition is designed for three-phase systems with voltages up to 66kV line end or 132kV neutral end and nominal rated current of 300A, 400A for linear regulation.
AT & ATV tap changers have a maximum of 17 tapping positions (16 steps) 15 possible for linear regulation and 33 tapping positions (32 steps) for reversing of course/fine regulation.
AT OLTCs are capable of reverse flow at full power. The OLTCs are a flange-mounted tapchangers where the oil in the switch compartment is kept separate at all times from the oil in the main transformer.
Manufactured in accordance with IEC 60214 and also complies with many other national and international standards.
