Unitised Substation

We are offering unitised substation.
Description
unitised substation are designed for locations where space and safety is a concern, population density is high, such as urban centre. Unitised substation is divided in three section or compartment � medium voltage, transformer and low voltage switchboard. Unitised substations are designed in accordance with is 14786 iec 61330 standards with degree of protection for ip23 for transformer and ip54 for mv & lv compartments or as per customer requirement.

assured features
windings are electrically balanced to minimize axial short circuit forces.
Coils are held rigidly in place between insulators clamped to the upper and lower core frames under high compression.
Precise casting under vacuum ensuring low partial discharge.
Smooth surface finish and robust construction of mv & lv cast coils.
Adequate ducts between coils, discs for maximum air flow and reduced hot spot temperature.
Step-lap designed crgo lamination for lower losses and excitation current.
