Ring Main Unit (RMU)

Compact / Unitised / Packaged Sub-station (CCS/USS/PSS)

We manufacture 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.



ADVANTAGES

·        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

APPLICATIONS

·        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.

Electrical Power Substation - Type of Electrical substation

Electrical Substation Now days the electrical power demand is increasing very rapidly. For fulfilling these huge power demands the modern time requires creation of bigger and bigger power generating stations. These power generating stations may be hydro-electric, thermal or atomic. Depending upon the availability of resources these stations are constructed different places. These places may not be nearer to load centers where the actual consumption of power takes place. So it is necessary to transmit these huge power blocks from generating station to their load centers. Long and high voltage transmission networks are needed for this purpose. Power is generated comparatively in low voltage level. It is economical to transmit power at high voltage level. Distribution of electrical power is done at lower voltage levels as specified by consumers. For maintaining these voltage levels and for providing greater stability a number of transformation and switching stations have to be created in ...

What Is Energy Efficiency Level 2 Transformer ?

High-efficiency transformers make financial benefits for the society. Other than diminished greenhouse gas emanations, they progress reliability and deliver possibly longer benefit life by bringing down temperature rises through energy-efficiency advancements. India has, by presently, received the universal IEC standards as well as presented star naming for chosen categories of transformers. Most power losses happen within the transformer core made up of magnetic steel or within the electrical coils or windings of either aluminum or copper. Copper diminishes load loss, since it could be a more proficient conductor. The significant Indian standard for distribution transformers (DTs) IS:1180/1989 has been changed within the year 2014 as IS:1180 (Part1)/2014 by Bureau of Indian Standard (BIS) subsequently superseding IS:1180 (Portion 1 and 2)/1989 both for fixed and non-sealed sort. This standard advance prescribes numerous reviewing with respect to vitality effectiveness, i.e. three ...

Ring Main Unit (RMU)

  Ring Main Unit,   RMU   is a compact, enclosed and sealed type of Switchgear used for medium voltage power distribution. It is a complete Switchgear in itself. A complete Switchgear means, assembly of required switching devices, protection device as well as metering device. RMU of different voltage (mostly 12 kV and 24 kV) and current ratings are available.  Indoor as well as outdoor types of Ring Main Units are available. Ring Main Unit comprises of one incomer feeder and one or more outgoing feeder. The incomer feeder is either Vacuum Circuit Breaker or SF 6  Circuit Breaker with associated Disconnect Switch and Earth Switch. This incomer feeder is given with the provision of bushing protruding from the enclosure of RMU for supply cable connection. A typical Ring Main Unit is shown in figure below. Outgoing feeder comprises of Load Break Switches with associated Disconnect Switch and Earth Switch. Provision for cable connection is provided in outgoing f...
