FL(R) N36-12 is 10 kV medium-voltage switchgear which has been developed by SOJO according to IEC and GB standards. The switch has passed all the related standards and has been used widely in 10kV variable power distribution system. 继续浏览
Features
FL(R) N36-12 medium voltage load switch had reinforced epoxy resin cast, which uses SF6 gas for insulation and also arc quenching medium. The gas pressure is 0.045Mpa.
Three position rotatable moving contacts for close, open and earthed operation.
The resin cast has anti-explosion pressure relief value fitted at back for ensuring safety of operators.
FLN36-12/T630-20 has single K-type spring mechanisms, normally used for incoming and outgoing line.
FLN35-12D/T125-50 has double A-type spring mechanisms, normally used together with fuse for transformer protection.
Build-in capacitive sensors
Optional motor operation
