ELDEE manufacture’s various modules of Indoor/Outdoor type Compact Sub-Stations upto 2500 KVA capacity, 33KV class of transformers with HT/LT switchgears.
The Compact Sub-Station (CSS) is also known as Unitised Sub-Station (USS) or Packaged Sub-Station (PSS). The Compact Sub-Staton is a compact arrangement, which replaces conventional sub-station arrangement consisting of Load Break Switch / Vacuum Circuit Breaker, Transformer, Distribution Panel, Lightening arresters mounted on a pole structure or on a platform.
CSS is designed, keeping in mind the personal safety & aesthetics, considering HT equipment is located in high density urban places. It is a pre fabricated secondary sub-station consisting of three compartments (i.e.) H.V.Compartment which houses Vacuum Circuit Breaker (VCB) or Load Break Switch (LBS), the transformer compartment which houses dry type /oil cooled transformers & the LV compartment which houses ACB, MCCB, SFU etc. as per client's requirement. All components are housed in an enclosure which protects the equipment against environmental hazards & unauthorized access . The electrical equipments are cooled by natural ventilation.
- Fully compartmentalized design
- Easy to install, operate & require very Less Maintenance
- Cost Effective & Space Saving
- Reduced Electrical Losses as CSS can be installed near the load centre
- A high degree of Safety & operational reliability is achieved by HT & LT switchgear with protective relays
- Reduction in logistic cost as the CSS is delivered as a single unit
- Tailored Configuration to meet customer requirement
- Due to the enclosed construction, it avoids Bird hit, human / animal contact which may lead to fatal accident and disruption of power supply
- Aesthetically enhanced look & designed to suit the site topography, which gives pleasing appearance
- No separate room is required
- Can be installed Indoor & Outdoor
- Load Break Switch with fusetrip& earth switch mechanism, shunt trip coil, HT HRC fuses
- Vacuum Circuit Breaker with metering & protection using current/potential transformers & relays
- Ring Main Units consists of Load Break Switches/Vacuum Circuit Breakers combination
- Oil Filled Transformer
- Dry Type Transformer
- LT Control Panel with ACB & MCCB
- SFU with metering
- CSS are ideally suited for residential and commercial complexes as it can be placed on ground floor or basement or roof top of the high rise buildings
- Mainly used by Power Utilities, Multiplex, Hotels, Hospitals, Shopping Malls, Software Parks, Airports & Residential complexes etc.
