Compact Switchboards
Safety-enhanced and compact-structured switchboard with MCBS (Molded Case Busbar System),
BMT's own patented technology.
Features
Compact structure to save space
- Reduces volume and busbar by more than 40% and 10% respectively, compared to conventional switchboards.
- The structure of separating each phase (R/S/T/N) reduces the restriction of clearance/creepage distance.
- Maximizes the practical space use of the electrical room and reduces construction costs.
- Height of electrical room : about 700mm ↓(For TR Capacity of up to 500kVA)
- Height of electrical room : about 500mm ↓(For TR Capacity of up to 750kVA)
- Height of electrical room : about 400mm ↓(For TR Capacity of up to 1000kVA)
Clearance/creepage distance of the BMT compact switchboard’s busbar
- Phase-Ground 50mm
- Phase-Phase 40mm
- Same Phases 50mm
Clearance/Creepage Distance for conventional HV switchboard (22.9kV)(Based on Article 108 and KEMC 2101))
- Phase-Ground 200mm
- Phase-Phase 215mm
- Same Phases 225mm
Convenient operability and expandability
- Modulization enables disconnection of individual module and partial replacement/repair.
- Simple extension and convenient connection with existing busbar lindes.
- Allows for a busbar system that can be installed without additional support insulators, and enables easy installation and maintenance.
Innovative safety and excellent durability
- A flame retardant material is applied to MCBS (PA66 GF30% Flame Retardant Reinforced) in order to eliminate the risk of accidents caused by electric shock or short circuit and to prevent fires from spreading.
- By maintaining the MCBS’s dielectric strength completely (up to 20 kV) with a closed structure separating each busbar, the systems and workers are safe from the risk of short circuit/ground fault/electric shock caused by incomplete power supply, moisture, dust, etc.
- Anti-loosening lock bolts are applied to busbar to protect it from vibration due to resonance, etc.
- An earthquake-resistant design (zone 4 level or seismic intensity 7) is adopted for the enclosure to enhance safety.

MCBS(Molded Case Busbar System)
MCBS is the world's first modular assembly busbar system made with BMT's own patented technology.
- The BMT compact switchboard with MCBS dramatically reduces the spatial constraints of power receiving facilities and electrical rooms in factories, buildings, etc.
- The closed structure made of the flame-retardant material protects against electric shock and short circuits, thus preventing fire and safety accidents
