Overview
FZW28F-12 The outdoor boundary vacuum load switch (referred to as FFK) is designed for pole-mounted installations and features both manual and automatic operation. The switch body is maintenance-free and utilizes vacuum arc extinction with SF6 gas as the insulating medium.
This product complies with the following standards:
GB3804-20043.6~40.5kV The high-voltage AC load switch complies with GB/T 11022, which outlines the common technical requirements for high voltage switchgear and control equipment. This manual describes the structure, functionality, and installation and debugging methods of the outdoor boundary vacuum load switch. The FZW28F-12 type outdoor boundary vacuum load switch is equipped with fault detection, protection, control, and communication functions. It is installed on 10kV lines and can autonomously eliminate single-phase grounding faults and automatically isolate phase-to-phase short circuit faults. It is suitable for T-junctions of 10kV distribution lines for user connections or can also be used at other branch line connections that meet the requirements.
