Description
The energy source of the U series has been developed using advantageous technologies such as solid insulation, vacuum breaking, and microelectronic control. The automatic recloser or circuit breaker on the three-phase column adopts the latest technology in solid insulation (hydrophobic cyclic grease), vacuum breaking, and insulation materials. This device does not use any gas or oil insulation medium. The isolation of the vacuum arc extinguishing chamber adopts a cycloaliphatic epoxy liner.
