• Applicable to 22.9kV-Y isolating/classifying distribution sections. For insulation,
epoxy and break vacuummethod used instead of SF6 insulating gas.
• Eco-friendly break vacuum method adopted as an alternative for SF6, which is a type of greenhouse gases
• Polymer insulation method adopted as it requires no steady maintenance
• Maximum switching performance with the use of vacuum interrupter
• Auto/manual control available, and remote operation available when operating an integrated terminating device
• Insulation cover connected to charging parts to prevent accidents caused by external contacts
• Easy detection of battery status and issues (remote monitoring also available)
• Epoxy bushing highly resistible to pollution for polluted areas
