Medium-Voltage Switchgear

MV Secogear Switchgear

SecoGear PV is metal-clad medium-voltage switchgear for utility, industrial, and building applications. It is designed, assembled, and tested to IEC 62271-200, with grounded metal barriers that segregate primary functions so no live parts are exposed. Safety interlocks, closed-door racking, a breaker position indicator, and positively actuated shutters are standard. The 40.5 kV configuration uses the SecoVac embedded-pole vacuum circuit breaker and is rated 630–3150 A, 50/60 Hz, with short-time withstand of 25 / 31.5 / 40 kA (3 s) and panel ingress protection of IP4X (compartment IP2X). It is used for safe switching and protection of cables, transformers, capacitors, motors, and other MV equipment.

Medium-Voltage Switchgear

SecoGear 12–27 kV Switchgear

SecoGear 12–27 kV is indoor metal-clad air-insulated switchgear for the MV section of HV/MV and MV/MV substations. It is designed, assembled, and type-tested to IEC 62271-200 (LSC2B, PM metallic partition) and IEC 62271-100, with earthed metal compartments, safety interlocks, closed-door racking, automatic shutters, and an embedded-pole SecoVac vacuum circuit breaker. Rated 12 / 17.5 / 24 / 27 kV, 50/60 Hz. Up to 17.5 kV the current range is 630–5000 A (4000/5000 A with forced cooling) with short-time withstand of 25 / 31.5 / 40 / 50 kA. 24/27 kV ratings go to 3150 A and 25 / 31.5 kA. Internal arc classification AFLR up to 50 kA / 1 s, enclosure IP4X (compartment IP2X). Used for switching and protection of cables, transformers, capacitors, and motors.
