Product Description

We are known as one of the leading manufacturers, suppliers and exporters of optimum quality Distribution Transformer. This transformer is admired in the global market for its longer service life, high efficiency and voltage capacity. With an ISO 9001:2000 certified mark, our offered products adhere with the set industry standards to ensure their flawlessness. We offer transformer that is used to carry electrical energy and provide electric supply in various industries. Available at affordable prices, we provide Distribution Transformer at the clients' destination within given time period.

Distribution transformer is used to convert electrical energy of higher voltage (usually 11-22-33kV) to a lower voltage (250 or 433V) with frequency identical before and after the transformation. Application of the product is mainly within suburban areas, public supply authorities and industrial customers. With given secondary voltage, distribution transformer is usually the last in the chain of electrical energy supply to households and industrial enterprises. 

Some of the salient features of Vener7 Distribution Transformers is as follows :


1. Core

Core is made from best grade imported cold rolled grain oriented silicon steel lamination with the latest technique of annealing. Interleaved and mitered joints reduce the core losses and magnetizing current considerably. Core is specially designed to sustain over-fluxing up to 12.5%. Core is clamped with steel channels rigidly to reduce the cartite sound level and earthed with electrical grade copper sheet.

2. Winding

The winding cab be of any type (i) spiral (ii) crossover (iii) helical (iv) disc, designed to withstand the optimum electrical, mechanical, dynamic and thermal stresses depending upon the current and voltage. The coils are wound with electrolytic grade high conductivity, annealed wire and strips covered with high quality insulation. All coils are reinforced, insulated to withstand the effect of short circuits and impulse voltage shocks. Cooling ducts are provided to minimize the hotspot temperature and temperature gradient between winding and oil.

3. Insulation and Oil

The insulation material like pre-compressed boards, blocks, corrugated cylinders, Bakelite tube, insulating tapes, empire sleeves, glass sleeves varnish, epoxy bushing, porcelain bushing etc. are used of best quality to ensure long life to the transformers. Oil used as a coolant and insulating medium is of the best quality conforming to IS: 335. Before filling into Filtration Plants and tested to ensure free from moisture and dust.

4. Tank and Radiator

The tanks are made from premium quality mild steel sheets, plates and pipes by electrical welding. Proper bracing and stiffeners are provided for robust construction. The tank are tested at specific pressure for leakage at joints/welds. Sufficient cooling radiators are provided for maximum dissipation of heat during extreme ambient temperatures. The radiators are made from best grade pressed steel fins or elliptical tubes.

5. Painting

Tank surface exposed to atmosphere is painted with two coats of red oxide paint to provide maximum resistance to corrosion and two coats of epoxy based anti-corrosive enamel paint. Surface in contact with oil is treated with two coats of 'Oil and Heat Resistant Paint'. This paint has more effective resistance compared to ordinary enamel paint against corrosion and oil/heat reactions.

6. Vector Group

Various vector groups can be provided as per demand.

7. Temperature Rise

Our transformers are designed for maximum temperature rise at full rated load 40 degree c/50 degree c for oil/winding for aluminium wound transformers and 45 degree C/55 degree C for copper wound transformers.

8. Overloading

Our transformers are designed for overloading excess than normal rating as per IS:6600.

9. Fitting and Accessories

Standard fitting recommended in IS 2026-1977 are provided. Extra fittings like buchholz relay, dial type thermometer, winding temperature indicator, marshalling box, H.V. & I.V. cable boxes, PRV and OSP are provided as per the requirement of the customers.

Distribution Transformer Applications:


1. Power Distribution: Distribution transformers are primarily used in power distribution systems to reduce the high voltage power from the transmission lines to a lower voltage that can be used by homes and businesses.

2. Industrial Applications: Distribution transformers are used in various industrial applications to power machines and equipment that require lower voltage power. They are used in industries such as manufacturing, mining, and construction.

3. Renewable Energy: Distribution transformers are also used in renewable energy systems such as solar and wind power systems. They are used to step down the voltage of the power generated by the renewable energy source before it is fed into the electrical grid.

4. Residential Applications: Distribution transformers are commonly used in residential applications to provide power to homes and apartments. They are used to reduce the voltage of the power supplied by the electrical grid to a level that is safe for use in homes.

5. Commercial Applications: Distribution transformers are used in commercial applications such as shopping malls, hospitals, and office buildings. They are used to power lighting, HVAC systems, and other equipment that requires low voltage power.

6. Rural Electrification: Distribution transformers are used in rural electrification projects to bring electricity to remote areas that are not connected to the national grid. They are used to step down the voltage of the power generated by local power sources such as small hydro power plants or diesel generators.

Frequently Asked Questions:


1. What is a distribution transformer?


Ans: A distribution transformer is an electrical transformer that is used to convert high voltage power into lower voltage power for use in homes, businesses, and other low voltage applications.

2. How does a distribution transformer work?


Ans: A distribution transformer works by using electromagnetic induction to transfer electrical energy from one circuit to another. It consists of two coils of wire, the primary coil and the secondary coil, which are wrapped around a common magnetic core. The high voltage power is applied to the primary coil, which creates a magnetic field that induces a voltage in the secondary coil. This voltage is then stepped down to a lower voltage that can be used by homes and businesses.

3. What are the different types of distribution transformers?


Ans: The different types of distribution transformers include pole-mounted transformers, pad-mounted transformers, and underground transformers. Pole-mounted transformers are mounted on utility poles, while pad-mounted transformers are installed on concrete pads. Underground transformers are buried in the ground.

4. What is the difference between a distribution transformer and a power transformer?


Ans: A distribution transformer is designed to step down the voltage of power from the high voltage transmission lines to a lower voltage for use in homes and businesses, while a power transformer is designed to step up or step down the voltage of power for transmission over long distances.

5. How long do distribution transformers last?


Ans: The lifespan of a distribution transformer depends on various factors such as the quality of the transformer, the operating conditions, and maintenance practices. However, a well-maintained distribution transformer can last for 25 to 30 years.

6. What are the safety precautions when working with distribution transformers?


Ans: Safety precautions when working with distribution transformers include wearing appropriate protective gear, ensuring that the transformer is properly grounded, and following the manufacturer's instructions for maintenance and operation. Only qualified personnel should work on distribution transformers.

7. How do you determine the appropriate size of a distribution transformer for an application?


Ans: The appropriate size of a distribution transformer for an application depends on the power requirements of the equipment being powered. The size of the transformer is determined by the kVA rating, which is a measure of the transformer's power output. A qualified electrician or engineer can determine the appropriate size of a distribution transformer for an application.
