FZW28-12F

OUTDOOR BOUNDARY VACUUM
LOAD BREAK SWITCH

Overview
FZW28F-12 outdoor boundary vacuum load break switch (FFK for short) is used for installation on the column, and has manual and electric operation
functions. The switch body adopts the VSP5-12 maintenance-free load switch imported from Japan Toshiba Corporation, and uses vacuum arc extinction
and SF6 gas as the insulating medium.
This product meets the following standards:
GB3804-2004 3.6 ～ 40.5kV high voltage AC load switch
GB / T11022 Common technical requirements for high-voltage switchgear and control equipment standards
This manual describes the structure, function, installation and debugging methods of outdoor boundary vacuum load switches.
The FZW28F-12 outdoor boundary vacuum load switch has fault detection, protection, control and communication functions. It is installed on a 10kV
line and can realize single-phase grounding fault isolation and automatic phase-to-phase short circuit fault isolation. It is suitable for T connection or
user terminal of 10kV distribution line user incoming line, and can also be used for other branch line connections that meet the requirements.
