Industrial, Substation & Distribution purpose Manufacturing range Upto 2MVA 22 KV naturally air cooled. A dry type transformer has an iron core, vacuum pressure resin impregnated high voltage windings and low voltage windings . The low voltage winding is constructed with conductors. Dupond nomex insulating material includes an apparatus to secure the windings in place during a vacuum and pressure resin impregnation process. The result is a coil that exhibits high short circuit protection due to the tightly bond conductors comparable to completely resin encased molded transformers at a substantially reduced cost.

Voltage converter which is without neutral and earth fault protection.Neutral earthing transformer has zig-zag (interstar) winding to achieve the required zero phase impedance. In addition an auxiliary winding can also be provided to meet the requirement of auxiliary power supply.

A distribution transformer is a transformer that provides the final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the level used by the customer. The invention of a practical efficient transformer made AC power distribution feasible; a system using distribution transformers was demonstrated as early as 1882. If mounted on a utility pole, they are called pole-mount transformers. If the distribution lines are located at ground level or underground, distribution transformers are mounted on concrete pads and locked in steel cases, thus known as pad-mount transformers. Distribution transformers normally have ratings up to 200 kVA, although some national standards can describe units up to 5000 kVA as distribution transformers. Since distribution transformers are energized for 24 hours a day (even when they don't carry any load), reducing iron losses has an important role in their design. As they usually don't operate at full load, they are designed to have maximum efficiency at lower loads. To have a better efficiency, voltage regulation in these transformers should be kept to a minimum. Hence they are designed to have small leakage reactance.

Step up transformer is connected to the power source and the other windings are known as secondary windings. There is a core with one winding of wire placed close to one or more windings, which can couple two or more alternating-current circuits together by employing the induction between the windings. If the secondary voltage wire is less than the primary wire, the transformer is called a step down transformer. If the secondary wiring is of higher voltage, the transformer is a step-up transformer, which increases voltage input.

Step down transformer are very easy and required devices. But the step down transformers continue to change with the latest updated technology as per their designs and materials. Step down transformers are electrical devices that change power via coupling. The primary winding is connected to the power source and the other windings are known as secondary windings. There is a core with one winding of wire placed close to one or more windings, which can couple two or more alternating-current circuits together by employing the induction between the windings. If the secondary voltage wire is less than the primary wire, the transformer is called a step down transformer.

Power distribution transformers are comprised of a plurality of conductor strands spirally wound for a plurality of coil layers. The low and high voltage winding sections are laterally spaced with the low voltage windings disposed in side-by-side positions and adjacent to the high voltage windings. The high voltage windings have a smaller turn height than the low voltage windings and have conductor strands of smaller gauge than the pancake coils of the low voltage windings.

L T transformers the dielectric insulating fluid in the transformer tank is completely sealed and is in zero contact to the atmosphere. The design avoids air in the transformer tank thereby avoiding sludging and oxidation of the dielectric fluid.

Industrial transformer , they are called pole-mount transformers. If the distribution lines are located at ground level or underground, distribution transformers are mounted on concrete pads and locked in steel cases, thus known as pad-mount transformers.

Hermetically sealed transformer is a transformer design which has no conservator. Here the dielectric insulating fluid in the transformer tank is completely sealed and is in zero contact to the atmosphere. The design avoids air in the transformer tank thereby avoiding sludging and oxidation of the dielectric fluid. Hermetically sealed transformers are totally maintenance free and are particularly suited for use in exposed outdoor environments such as moisture, salt or dust laden atmospheres. They are used extensively in chemical plants, oil and gas terminals where poor accessibility makes regular maintenance impracticable. Transformers immersed in synthetic coolants are suitable for use indoors with adequate ventilation or near to the load center where oil would not be considered environmentally acceptable. Normally these type of transformers are accommodated by devices that measure heat related volume variations. Gas cushion is used to compensate the volume variation due to heat. Normally the gas is nitrogen. This gas is thermally uncoupled from the dielectric liquid.
