Modern Transformers Private Limited

We manufacture CRGO Lamination For Transformers with following functionality:

• Slitting :- The CRGO steel is received in the form of coil and can be silted in the minimum  width of 5 mm and multiples of 5 mm. The cutters are frequently grinded to control the burr level.
• Shearing :-  The silted coil are sheared in the treadle shearing machine at an angle of 45 deg. & in case of mitered core and 90  deg in case of rectangular core. Utmost care is taken in grinding of the blades at specific interval of time   in order to minimize the burr level not exceeding than 10 micron.
• V-Notching :- The process of V-notching in the yoke plates of the stacked lamination are carried out in semi automatic power presses using dies made of tungsten carbide for achieving almost zero burr level.
• Stress Relieving Annealing :-  During the course of process the stresses developed in the stacked lamination tend to increase the losses and magnetizing current of the core. This is relieved by subjecting the lamination in roller hearth stress relieving  annealing furnace.
• Testing :- Random tests are conducted on sample of the CRGO Packing. The CRGO Lamination are packed on the wooden pallets and covered  by the water proof hessian cloth duly strapped in order to avoid damage to the core edges. Lamination for measurement of losses, insulation resistance, bend test, burr level etc.

We manufacturer MS Tanks For Transformers. Our manufactured transformers tanks are readily accepted by leading manufacturers of transformers in India. These transformers tanks are manufactured by tested MS material procured form reputed manufacturers and fabricated with the help of most modern welding equipments to ensure best quality of welding.

At Modern we have a well established quality system. Modern has a stringent incoming material and in-process quality plan, routine inspection.

Features:

• All transformers tanks after welding undergo a full dimensional check.
• All tanks are pressure tested individually under water for leakage test.
• After painting the paint thickness is measured on all tanks. Paint peal off test is performed on randomly selected tanks.
