Dragline Excavators rely on SES Drive-Isolation Transformers

Dragline Excavators are some of the largest vehicles on land. Standard isolation transformers are not designed to handle the extreme mechanical, electrical, and environmental conditions that this machinery are subject to, so we also manufacture a special type of transformer to cope with these extreme requirements – drive-isolation transformers.

SES has been supplying ABB (previously GE International) and their mining customers with a wide range of drive-isolation transformers, as well as other transformers and power supplies, for use in its Queensland and NSW mining operations for more than 20 years.

Drive-isolation transformers are designed to handle high mechanical stresses, as well as prevent harmful harmonics and voltage spikes from flowing back into electrical supply lines, which could result in damage to other electrical equipment. SES has been supplying drive-isolation transformers to the mining industry for over 20 years for use in draglines and similar equipment, where they are subject to high vibration and harsh environmental conditions.
