By manufacturing both the bus duct and switchgear, we ensure efficient integration of components on site.
Our equipment is developed on world-leading design and technology and proven acceptance. Available in single-phase systems for 15 kV / 16.7 Hz and in single phase or two-phase systems for 27.5 kV / 50 Hz, the MCS air insulated metal clad switchgear switches and protects the main railway traction circuits including the overhead line.
