Indoor AC high voltage isolation vacuum load switch

Outline

TFZN-24D / T630-20 indoor AC high voltage vacuum load switch and TFZRN-24D/T125-20 indoor ac high voltage vacuum load switch fuse combination (hereinafter referred to as “TFZN-24 series vacuum load switch”) are designed and developed by our company based on GB83804-2004, GB16926-1997 and Q/GDW Zhejiang province electric power company enterprise standards. TFZN series vacuum load switches have obvious visible isolation fracture, long electric life, frequent operation, large switching current, basic maintenance free, manual and electric operation function, and it can achieve long-distance control and other advantages. It is suitable for AC 50Hz, rated voltage 24KV network, and it can switch off active load current (capacitive load), overload current and short circuit current. It is installed in ring network switchgear, box substation and wall mounting.

Use

TFZN-24 series vacuum load switches are suitable for 50 Hz rated 24KV power grid to switch off load current overload current and short circuit current. Visible isolation fracture can ensure the safety of live maintenance personnel. It is especially suitable for places without oil, maintenance and frequent operation.
