NEX METAL-CLAD SWITCHGEARS Medium voltage metal-clad switchgear is one of the most important units in the power supply distribution system. On the basis of its longterm experience of equipment supply Pluton offers as MV switchgears NEX cubicles manufactured under license of Schneider Electric Company. NEX is indoor, metal-enclosed switchgear designed for step-down and distribution substations, and also for distribution centers. NEX integrates a host of innovative solutions designed around proven techniques and includes: high performance switchgear, digital protection, monitoring and control...

MAIN COMPONENTS OF SWITCHGEAR NEX Current transformers Evolis Vacuum Circuit-Breaker Evolis circuit-breaker is used to protect and control MV public or industrial distribution network. Technical parameters of Evolis circuit-breaker: • Rated operating voltage up to 17.5 kV • Short circuit breaking capacity up to 31.5 kA. • Rated current from 630 A to 2500 A. • Axial magnetic field (AMF) breaking technology. • Withdrawable version. Special configuration of working contacts in circuit-breaker vacuum chambers and arc movement during its “blowout" provide maximum possible in this type of...
