MODUTEC MV Basic Kit range is an indoor switchgear flat pack assembly that provides maximum user safety, simplicity and reliability during installation, operation and maintenance. It meets all electrical distribution needs up to 33 kV and incorporates a set of innovative solutions. With the combined experience of the MV Switchgear manufacturer and MODUTEC, we are now offering our MODUTEC Basic Kit with Type Test Certification/compliant to IEC 62271-200. We have developed draw out mechanisms, shutter assemblies and different types of spouts with investment in R&D, dies and fixtures for different makes of MV Switchgear.

I started business as an Electrical Stockist and then went up the value chain with Product solutions in terms of LV Switchboards. We further upgraded ourselves from making these in welded fabrication to a modular system. Having done this and experienced the advantages of the modular flexibility, adaptability and versatility, and when we went on to serve the Industry with 3.3kV to 33kV Medium Voltage Switchboards, we did these also in a modular design.
With just 2 punched and bent profiles we were able to build the entire skeleton of the Switchboard and then embellish it with the partitions, bus bar supports and doors etc. This helped us simplify, standardise and scale our business both in LV & MV.
Moreover, when we studied the trend abroad, in advanced countries, we reckoned that the typical Panel Builder is focused only on his core competency of 'electricals' while he outsourced his requirements of 'mechanicals'. In India too, Schneider are on the threshold of introducing the Prisma Switchboards with a HUB & SPOKE Model; ie a central point of Enclosure manufacturing and several Alliance Partners in different parts of the Country to assemble these Type Tested Enclosures with their switchgear.
If we study the growth of modular switchboard enclosure systems manufacturing companies like Elsteel, Cubic and Logstrup too, we will find that they are heavily 'mechanical' focused, while their Customers are all largely 'electrical' focused. It's a WIN-WIN as each does most, what they do best. Economies of scale for each therefore bring out the best value for the Customer techno-commercially. The idea that struck us is why not replicate the same in Medium Voltage?
The majority of the MV Panel requirement followed a particular rhythm of compartmentalization, of Type Testing as per IEC 62271-200 and then the Internal Arc Test. Variants to these would be the double bus bar arrangement, the 2 tier VCB arrangement but these are in lesser frequency. However, these too could be catered to from our modular design concept to individual Panel Builder specification.
Rationale behind the MV Basic Kit and it's augmenting simplifying panel building.
The Panel Builder ideally focuses on his core competency of 'electricals' while he outsources his requirements of 'mechanicals'. The mechanicals are manufactured in MODUTEC which becomes the HUB of the HUB & SPOKE Model; ie a central point of Enclosure manufacturing and several Alliance Partners in different parts of the Country to assemble these Type Tested Enclosures with the respective switchgear.
The majority of the MV Panel requirement follow a particular rhythm of compartmentalization, of Type Testing as per IEC 62271-200 and then the Internal Arc Test. Variants to these would be the double bus bar arrangement, the 2 tier VCB arrangement but these are in lesser frequency. However, these too could be catered to from Modutec's modular design concept to individual Panel Builder specification.
On close examination, we found that
The Internal Arc Test is mainly for the MV compartments of a, b & c above.
Each of the above 3 compartments had to be air tight to enable the gases generated from the possible internal arc in any of these 3 compartments, to open the respective pressure flap on top of the Panel. When & if this happens, the resultant gases are channelized out, thus protecting the blasting off of the Switchboard door and flying of parts, on to the operating personnel in front, rear and sides of the panel, to comply with AFLR internal arc classification.
We first separated our VCB into a separate air tight module as a "Power Module". This comprised of the bare VCB as supplied to us by Schneider Electric. We then developed the draw out mechanism for this VCB with the shutter assembly and spouts to take the 3 poles of the VCB out onto the Bus Bar Chamber on top and the cable chamber below.
This VCB module sits on our modular frame at the bottom as well as at the back. The bus bar compartment on top is completely segregated by a sheet metal partition that keeps the section air tight and mechanically robust to help withstand the short circuit currents as required. Accordingly, the outgoing cable chamber automatically becomes air tight and internal arc fault ready.
Each of these 3 compartments are now ready as air tight parts of the MV Switchboard with the flaps on top to release the Internal Arc pressure, in the event of a fault.
Handling of internal arc situations does not get limited to designing the panel to withstand the internal pressure developed during such a fault, but also extends to the subject of disposing off; by carrying the arc products to a much safer place away from the people. This task will involve adding the arc ducts over and above the standard MV panel, to carry away the arc products and also to cool and absorb the arc energy as it travels in the arc duct. Design and supply of arc ducts to suit specific installation site conditions is taken up based on specific customer requirements.
Thus, the modular 11kV VCB Basic Kit emerged as a possibility. It can be shipped as a Flat Pack with the VCB and accessories separately packed. An instruction manual would then assist the Panel Builder in putting the MV Switchboard together along with the Breaker draw out mechanism, the shutter assembly, the spouts with a provision to mount the bus bars. In the cable chamber, then the CTs and as required PTs could also be mounted. On top of the VCB Power Module, the LT Chamber can then be fabricated/ sourced by the Panel Builder and mounted as this would be dimensioned on the height based on the number of relays and meters the specific project requirement would need.
The significant advantages & benefits that the use of the modular VCB Basic Kit would deliver to the Panel Builder are:
So, what is being aimed at is to create the making of the MV Switchboard foray possible for the Panel Builder who desires to upgrade his manufacturing capability to include this range of switchboard offering as well. Thus, MODUTEC's centralized mechanical modular Basic Kit manufacturing facility, can serve the needs of several Partner Switchboard manufacturers who could just assemble these flat packs in their facility. This would empower them to make available Type Tested MV Panel Enclosure systems, to reach their Customers without actually spending money in this expensive and specialized Type Testing.(
The further benefits of this arrangement would be that
All this concept, simply emerged from a dream to reach MV as well as, of course, LV Switchboard solutions also to a larger electrical installation base in an organized, economical and authentic manner. Done well, this has the potential, we believe, to scale the Switchgear sales significantly and renders availability of the MV & LV Switchboard solutions through multiple partners to a larger and wide spread Customer base.
If you would like to know more about this concept, that's evolving from 11 kV & up to 33kV and be part of our mission in Simplifying Panel Building, do get in touch with us at [email protected] . It takes a lot to electrify India. And the un-electrified parts of our Country and also the world, can't wait!
