Modular traction substation.  Design

The number of cubicles in the modular traction substation is represented to suit standard network topology and can be adjusted to suit particular needs of the customer.

Modular traction substation is a functionally finished product with provision of power and auxiliary circuits connection points. 

Modules are mechanically independent and can be installed in accordance with the design solution. 

Reliable power supply is provided by power distribution equipment, automatically controlled by SCADA system. Auxiliary system provides operating power supply to all vital systems. Each modules have robust structure, designed for electrical installations weight up to 22 tons. The modules are dust and moisture resistant with IP55 protection level in accordance with IEC 60529 . Substation modules are lined with steel sheets with corrosion resistant and weatherproof coating. Floor, walls and roof are thermally insulated. 

External materials are fire retardant with low smoke and halogen free emission. All metal parts of the module are treated to avoid corrosion. Each module is equipped with ladders and drains. Substation is equipped fixtures for loading and unloading.

Each module is structurally divided into two compartments: transformer compartment and switchgear compartment. Each module has individual earthing point.

Equipment in modules is located in accordance with functional groups.
