Benefits of Modular design:
QUICK DELIVERY
The skeleton of the Panel is made from just two profiles, the Vertical and the horizontal members. The rest of the partitions, base plates, base channels and doors are all standardized for different sizes in multiples of 30 mm in X, Y and Z axis. All these components are stocked based on the concept of minimum reorder volumes. Hence the deliveries are practically possible for quick delivery
FLEXIBLE
Scores of standardized components go to make the Modular design. These are versatile in the features of inter-changeability; can accommodate late minute component additions, changes and even have the doors reversible from left to right and vice versa! Any make of electrical switchgear can be accommodated with ease and extensions to the panels can even be done at site with precision. The panels can be made in Form 1 to Form 4b with all variations including single and double front.
COST EFFECTIVE
Standardization helps scaling. The result is economies of scale. The beneficiaries are our customers and end users. Further the profiles are not only with 3 / 4 bends but also punched with 6.5 dia holes at 30 mm interval delivering modularity to our switchboards. This also renders the Panels rugged, sturd and reliable yet being light weight. Less material, more technology, less cost & less scrap!

Salient features of the panels
Use of non-hygroscopic SMC supports for Bus bar for adequate mechanical and electrical strength to withstand specified full current.
Panels are totally enclosed, dust proof and vermin proof, and fully compartmentalized, cubicle design and modular construction. The covers and doors are well gasket with neoprene rubber gaskets so as to obtain dust proof enclosure.
The panels are manufactured with separate Bus bar chamber isolated from Unit feeder chambers and Cable Alleys. This provides extra safety for working personnel.
The panels are made of 2/1.6mm thick CRCA / Special grade GI sheet steel for robust construction. The doors are provided with concealed hinges for better aesthetic appearances.
All sheet metal work is processed using CNC Laser machines and CNC Press Brake machines, resulting in desired accuracy.
Standardized & Optimized design and size of Panels, compartments, Bus bar Chamber and Cable alley.
The panels are treated for de-greasing, de-rusting, Phosphating and Passivation by adopting eight tank processes as per the Indian Standard Specification before powder coating with epoxy based powder.
All Control and Power wiring terminals are brought out in the Cable Alley for easy cable termination.
All Power and Control wiring is done using numbered ferrules of proper size and quality at both ends for identification. The wiring is neatly bunched and kept in the PVC trunking and closed by a cover for a clear wiring.
All Bus bars are insulated with heat shrinkable PVC sleeves and all the live parts are shrouded to avoid accidental contact.
