Solid Load Break Switch for 25.8 kV (Overhead Line) | Solid Load Switchgear

• Applicable to 22.9kV-Y isolating/classifying distribution sections. For insulation,

 epoxy and break vacuummethod used instead of SF6 insulating gas.

Solid Load Switchgear
Features

• 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
