500 kVA 27.6 kV Transformer

500 kVA 27.6 kV Transformer

This 500 kVA transformer is designed with a dead-front configuration and follows a loop feed layout. Crafted by Daelim Transformer, a company with cUL certification, this transformer is tailored for a Canadian clientele. Its specifications include a high voltage of 27.6 kV in a Delta connection, while the low voltage stands at 600Y/347V. It adheres to the CSA C227.4 Standard, with a focus on energy efficiency aligning with the CAN/CSA 802.1 Standard.

The 500 kVA transformer is equipped with 6 loadbreak bushing inserts (rated at 35kV, 200A), 3 elbow arresters, 6 HV bushing wells, 4 LV bushings (each with 4 holes), and a four-position loadbreak switch. Notably, the transformer is fitted with a vacuum pressure gauge, a temperature indicator, and an oil level gauge. These components are equipped with contacts and feature alarm functionality, enabling remote monitoring of the transformer's internal conditions.
