12kV 24kV 40.5kV Indoor SF6 Load Break Switch

Additional information

Product Details:

Introduction

FL(R)N36 Indoor AC High Voltage SF6 Load Break Switch and LBS-Fuse Combination are used for the three-phase AC 50/60Hz RMU and terminal power station. The switches are suitable for protecting the 10kV, 24kV and 35kV power system’s on load situation. The switch can switch off the on load current, closed loop current, no load transformer capacity and cable charging current. The switch with fuse combination can cut off any current, when the current is in the range of the rated short-circuit breaking current. They are suitable for the RMU, combined transformer, etc..
