General Description   HXGN15-12 switchgear metal enclosed AC ring main unit is a new apparatus which introduced from abroad and accord with the requirement of rural distribution and city distribution in nation. Main switch, operation mechanism and component use the SFL-12/24 model SF6 switch equipment produced by ABB Company or FLN36-12D model SF6 switch equipment produced by our company. Also can use the HAD/US model SF6 circuit breaker or VD4-S model vacuum circuit breaker produced by company ABB according to requirement of customer operation type is manual and motor.         Model Definition       Operating Condition Ambient temperature: -25°C-40°C; Altitude: ≤3000m Relative humidity: daily average≤95%, monthly average≤90%; Applicable occasions without flammables, explosives, corrosives, frequent severe vibration and strong shake.       Design Feature Panel structure: the panel body is enclosed by 2 mm aluminum-zinc plated steel plate after multi-bending. It is simple, firm, delicate and peculiar. Bus bar compartment: the bus bar compartment is located in the top and connects with neighboring panel. Load break switch is a separated unit with SF6 gas. Cable compartment: approximately 75% room for connecting cable and installation fuse, earthing switch and PT. Mechanism chamber and interlock: the chamber consists of operating mechanism, mechanism interlock, position, indicator, auxiliary contact trip coil, charge indicator and interlock. LV chamber: LV chamber is located in the top. It mainly user for installing instrument, relay and motor. Circuit breaker compartment: the circuit breaker (SF^ or Vacuum) is located below load break switch.   Pressure release: Upper pressure release: it is mainly used for releasing gas pressure which produced by arc accident in bus bar load break switch compartment. Down pressure release: it is mainly used for releasing gas pressure which produced by arc accident in cable small compartment.       Technical Parameters
