Product Description
The FL(R)N36-12D SF6 High Voltage load Break switch is an indoor switchgear with a rated voltage of 12KV. It uses SF6 gas as the arc extinguishing and insulating medium, and has three positions: closing, opening, and grounding. It is characterized by its small size, convenient installation and use, and strong adaptability to the environment.
By combining the FL(R)N36-12D indoor high-voltage SF6 load switch with other electrical components, control and protection functions can be realized. It can be used for the control and protection of electrical equipment in industrial and mining enterprises, civil power supply systems, and secondary substations. Among them, the load switch-fuse combination electrical appliance matches the protection characteristics of the transformer and is especially suitable for ring network power supply units.
The FLN36-12D/630-20 SF6 High Voltage load Break switch (hereinafter referred to as the load switch) and the FL(R)N36-12D/100-50 combination electrical appliance (hereinafter referred to as the combination electrical appliance) comply with the national standards GB3804 "3~63KV AC High-voltage Load Switches" (EQV IEC60265-1) and GBL6926 "AC High-voltage Load Switch-Fuse Combination Electrical Appliances" (EQV IEC420).
