Product Introduction

SUMMARY

 

XGN15-12L HV switchgear metal enclosed AC ring main unit is a new HV 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 model SF6 switch equipment produced by ABB company or FLN36-12D model SF6 switch eq uipment 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.

 

 

OPERATING CONDITIONS

 

1. Ambient temperature: -25 ~+40;

2.  Altitude: 1000m;

3. Relative humidity: daily average 95%, monthly average 90%;

4. Occasions without flammable and explosive matter, without corrosive chemical and frequent severe vibration, without strong shake.
