1. Brief introduction PLBS Pole mounted SF6 load break switches are designed to meet growing requirements for Reliability. Switches filled with SF6 gas as the insulating and arc quenching medium with puffing principle. It can be used in 12kv,24kv,36kv overhead line.  It has excellent load breaking and fault making capacity. It has three kinds of operating mechanisms: manual, motor, intelligent The basic mechanism is operator independent quick close and quick open spring toggle mechanism. The motor operating mechanism is developed to meet the feeder automation in addition to the manual switch.    2.Features -various bushing types Besides standard porcelain bushings, we can also supply rubber bushings. -Visible open and close status. It is easy to see clearly the main contact position indicator ( green-open, red-close). This indicator is directly connected with main contact drive shaft assembly so that it can show contact status exactly. -fast operation Spring energy storage operating mechanism can quickly open and close (less than 1 second). -remote control Electronic controller is equipped. Users can operate locally, or operate at master station through FTU interface.    3.Brief specifications
