MV Switchgear & Switchrooms
Medium voltage switching and protection for primary power distribution.
Overview
Basiia supplies Medium Voltage (MV) switchgear, ring main units (RMUs), and complete switchroom packages for primary power distribution in industrial facilities, substations, and utility networks. Our MV switchgear solutions cover 3.3 kV to 36 kV systems — including air-insulated switchgear (AIS), gas-insulated switchgear (GIS), and vacuum circuit breaker (VCB) panels — with integrated protection relays, metering, and SCADA connectivity. We manage the complete switchroom scope including civil, structural, earthing, and commissioning.
Typical Applications
- Primary substation MV switching and protection
- Industrial facility MV distribution (6.6 kV, 11 kV, 33 kV)
- Ring main units (RMU) for distribution networks
- Motor feeder protection for HV motors
- Transformer primary protection and switching
- Generator interconnection and protection
- Renewable energy (solar/wind) grid connection
- Utility and grid substation equipment
Key Features
Engineered for Performance
Vacuum Circuit Breaker (VCB) Panels
Metal-clad and metal-enclosed VCB switchgear for 3.3 kV to 36 kV — fixed and withdrawable designs with arc flash containment, interlocking, and integrated numerical protection relays.
Gas-Insulated Switchgear (GIS)
SF₆ or clean-air insulated GIS for compact substation footprints — suitable for indoor, outdoor, and space-constrained installations with reduced maintenance requirements.
Ring Main Units (RMU)
Compact, sealed RMUs for distribution network switching and protection — load break switch, fuse combination, or circuit breaker configurations for ring and radial network topologies.
Numerical Protection Relays
Integrated numerical protection relays (Siemens SIPROTEC, Schneider Sepam, ABB REF/REL) for overcurrent, earth fault, differential, distance, and busbar protection — with IEC 61850 GOOSE communication.
Complete Switchroom Packages
Turnkey switchroom delivery including prefabricated building or civil works, MV switchgear, LV auxiliary boards, earthing system, cable trenches, lighting, and HVAC — single-point responsibility.
Commissioning & Testing
High-voltage testing, protection relay testing and setting, interlock verification, and power system studies (load flow, fault level, arc flash) — with full commissioning documentation and as-built drawings.
