Description
Before dead-front technology became a utility standard, CES first designed and manufactured live-front transformers. With utilities being experts in HV line work many still prefer the live-front standard which eliminates the requirement for costly elbow and bushing well terminations. CES can customize the layout and orientation of LV and HV compartments to cater to our customers project requirements.
