Our Infrastructure
   

Located in Vadodara (Gujarat, India), our production facility spans across a vast area. It comprises two major factories located in the reputed industrial areas of the city. Each Factory has area of about 50,000 sq. ft. on over 2.19 acres.Our manufacturing unit is equipped with hi-tech equipment, which includes hydraulic power press welding agents, hydraulic bending and shearing machinery, hydraulic press breaks and CNC Plasma Cutting/Oxy Fuel Machine. The company can easily make assemblies on the basis of welding facilities of CO/MIG/MAG & Arc. Powder coating and epoxy painting is done using machinery, which helps in proper surface treatment like 7-tank treatment, shot blasting and final finishing. With the help of the cutting-edge CNC machine technology installed within the manufacturing unit,

We undertake the following at competitive market prices:

  • Cut to size shearing, bending, rolling and various other sheet metal work
  • Coil de coiling –leveling – shearing facility of any length with upto 3 mm thickness and 1500 mm width
  • Supply of Mild Steel and Stainless Steel Sheets, Angle, Flats, Channel, Beams(H- I), Pipe, Rod
  • Supply of Transformer Tank parts inclusive of Top Cover cutting and holes through CNC plasma cutting and top cover embossing plus tank parts’ Shearing, Bending, Rolling, Corner Cutting
  • Fabrication of M.S. Transformer Tanks with the help of advanced welding, grinding and drilling machinery
  • Frame parts for M.S. Transformer Tanks
  • Surface preparation through shot blasting, liquid dipping

 

Manufacturing Facility

The prime material in a transformer is the core. Nakoda uses high quality Cold Rolled Grain Oriented Magnetic Silicon Steel to ensure optimum losses and most efficient working of the transformer. The type of magnetic steel is chosen according to the desired loss level. The lamination are cut geometrically to ensure optimum flow of magnefic flux and minimum or gap between the art of two consecutive sheets. The supporting structures and clamping devices of the core contribute to the compactness of the design and also ensure low sound levels.

 

The Core: Rectangular and round conductor are used for the windings. The conductor is usually insulated with either high-grade multi paper covering or with an insulating enamel coating. The windings are such designed sues to ensure reduced axial stresses in Short circuit conditions and also to withstand impulse and over-voltages. Some standard forms of coil windings are spiral, helical, interleaved disc and plain disc. For Power Transformers, both low voltage and high voltage windings are disc type, which give highest resistance against short circuits. It is ensured that proper tension is given on the winding for rigidness.

 

The Winding: The "active" part of the Transformer consists of the magnetic core with windings and accessories. The windings are placed over the core limbs and necessary connections are made as per the tapping and vector group. Sufficient ducts are provided between the coils to ensure heat dissipation through circulation of oil. Best quality insulation is provided at all joints and gaps. The optimum design of Core-Coil Assembly is achieved by consider the required technical particulars, cooling, size compactness and tapping arrangement. All leads and conductors are rigidly supported by special wooden frames.

Core-Coil Assembly:
The Core-Coil Assembly is placed in the vacuum oven for removal of moisture. After the drying process, the assembly is tightened to take up all shrinkage and then the unit ready for tanking.

Vacuum Drying:
After removing the Core-Coil Assembly from the heating oven, it is thoroughly cleaned by pressurized air and then placed into the tank and bolted up. All necessary accessories / fittings such as bushings, valves, oil level indicator, pressure relief device, temperature indicator, tap changer etc. are fitted on to the tank body. High quality filtered transformer oil is then filled in the tank to completely immerse h e assembly. Finally connections of primary and secondary to the terminal.

Tank-up:
Tanks are made of high quality odd steel sheets and plates. State-of-the-Art welding technology is applied to give immaculate finish and leak proof tanks. Cooling is provided by either Pressed Steel type Radiators, which are attached by flange of welded directly onto the body, or by corrugated fin walls. Either types of tanks can be supplied as per customer's requirement, however, corrugated type tank has merits over conventional radiator type tank because of its compact size and aesthetic, Every 'ranks is rigorously tested for any leakage or seepage. air pressure test, fluid test and ultraviolet amp test are conducted on each tank to ensure that no leakage takes place. Continuous efforts in Research and Development result in excellent finish, leak proof and rigid tanks.

Warehousing and Packaging

We have established a vast warehouse on our premises. The building is built in accordance with the specifications provided by talented architects. It is capable of storing vast quantities of our products in a pristine condition. We have segregated the warehouse into many sections so as to store the products in a categorical and cataloged manner. The warehousing professionals keep the premises clean and tidy, while ensuring that the atmosphere remains well ventilated. Our packaging professionals are capable of undertaking large scale packing of products in a short period of time. They guarantee the timely delivery of products at the client’s premises.
