XGN68-12(F), XGN68-12(F.R), XGN68-12(Z) Box Type (Indoor) AC Metal-clad Switchgear is the latest HV electrical complete set of equipment which is researched and manufactured by our company together with Beijing Electric Power Research Institution.
ZN100-12 vacuum circuit breaker and FZN58-12 vacuum load switch in XGN68-12 Series Switchgear adopt vacuum interrupter epoxy resin sealing technology, with beautiful appearance, good insulation performance and convenient operation. The patented rotary fuse structure is adopted in the cabinet, which makes the replacement of fuse realize the draw out type, which is particularly convenient.
XGN68-12 Series Switchgear is the smallest in the air insulated cabinet. It meets the environmental protection requirements for urban users and residential areas, and the effective floor area is the smallest.XGN68-12 Series Switchgear is the most ideal choice.

3. Product Feature And Application
a. Vacuum load switch in HV room is maintenance free, the corresponded operating mechanism also needs little maintenance.
b. Simple and reliable mechanical interlock operates easily and prevents malsoperation.
c. Every functional compartment is separated from each other, and is equipped with pressure relief channel to prevent breakdown from expanding and extending.
d. Insulation distances and cable terminal contacts could be watched through observing window.
e. The secondary components room has plenty space, which is convenient to wiring. There's rich space in cable room, it is suitable for kinds of regular cable connection.
f. Fuse included in composite apparatus can be draw out for exchanging, it is simple and convenient.
g. It has small volume, only 50% volume of general switchgear.
