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.
Technical specifications
mv switchgear- 3.3 to 33 kv
type of switchgear- lbs sfu breaker rmu
insulation medium- sf6 gas or vacuum
tripping- fuse relay
short circuit rating- up to 20 ka or as per customer requirement
type of cooling- oil immersed dry type
rating- 100 to 2000 kva
voltage -3.3 to 330.433 kv or any specific
phase frequency- 3 phase 50 or 60 hz.
Vector group- dyn1 or dyn5 or dyn11 or any specific.
Mv switchgear- acb's, mccb's
current rating- up to 3250 amps
voltage- 433 volts
no. Of poles- 3 4
short circuit rating- 50ka 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.
