pole mounted transformers in extensive rural area

pole mounted transformers are used in extensive rural area. These polemounted transformers range from 3kva transformer to 167kVA transformer and transform 11,000 to 33,000 volts down to a low voltage of 400 volts. Pole mounted transformers (50 kva pole mount transformer)are reasonably small in size and mass so that it is easy to install them on single pole structures, and larger units on two-pole structures, approximately 5 meters above the ground. This makes the pole mounted transformers inaccessible, reducing the risk of injury to animals and people and minimizing vandalism.

Oil-immersed transformers to a energy saving and environmental protection

Oil-immersed transformers are a relatively traditional electrical equipment, especially in the use of oil-immersed transformers for economic development has an important role, and thus for the industry is advancing with the times, oil-immersed transformers The oil-immersed transformer (50kva power transformer)oil is also constantly improved, mainly to improve the use and quality, making the oil-immersed transformer work more smoothly, improve efficiency. And with the development of the market and the needs of social development for the oil-immersed transformer industry is also toward the direction of energy-saving development. So for oil-immersed transformers in terms of oil is constantly improving, toward a more energy-efficient and environmentally friendly direction to develop!
In the view of some experts, the use of traditional mineral oil oil-immersed transformer oil, oil type transformer and other electrical equipment may not be in the short term failure, but there may be risks in the long run. Some substandard oil-immersed transformer oil is corrosive sulfur caused by oil-immersed transformer winding burn failure, causing the direct cause of the accident for the choice of oil-immersed transformer oil improper. Some oil-immersed transformers after about 10 years of operation, the oil-immersed transformer oil contained in the sulfur will lead to oil-immersed transformer breakdown burned, resulting in improper selection of oil-immersed transformer oil caused by the accident.
It is understood that the base oil of oil-based oil does not contain sulfur, can be practical application of sulfur caused by the corrosive problem to a minimum. At the same time, gas production of low-temperature performance better, in the winter in Harbin can be used normally. In addition, the oxidation stability of gas oil has a significant advantage, can effectively extend the service life of oil, flash point of 191 degrees Celsius, a substantial increase in safety standards, and oil consumption is significantly reduced by nearly 25%, protection of oil-immersed transformers Equipment safe, durable and efficient operation.
With the further promotion of the product application, I believe it will help users to control high-pressure challenges, and continuously improve the level of operation and maintenance equipment. In the Chinese market, Shell electrical insulating oil "Dayana" S4 also performed well. In addition to the new installed power transmission equipment, with the large and medium-sized cities to upgrade the power grid and the construction of small towns to promote the Shell electrical insulation oil "Dayana" S4 can help oil-immersed transformers to achieve better low energy consumption, High reliability and efficient operation, help China's power industry to a more secure, more efficient development of the road.
Oil-immersed transformer oil for the continuous transformation of the environment and the use of oil-immersed transformers will be a huge change, and thus for the oil-immersed transformer manufacturers to increase efforts to produce more environmentally friendly oil Immersion transformer oil, to promote the industry to continue to update and development, in the development of oil-immersed transformers to make out to contribute!

single phase pole mounted transformers

single phase pole mounted transformers are usually used in rural areas where three phase power may not be required.  These Transformers reduce the voltage from the line voltage 11kV to a single phase voltage usually 230V.The secondary of the Pole mounted Distribution is usually connected between the two phases of a MV line.  The secondary voltage is a single phase voltage which is fed to the house.  These transformers (includ 50 kva pole mount transformer)can be easily installed and do not require extensive mounting Structures.Pole mounted Transformers come in sizes up to 500 kVA.These transformers have a fuse to protect against faults inside the transformer.  They are also equipped with an interrupting device.  These Transformers are tested to withstand the impulse of lightning. In the US, The secondary of these transformers has a centre tapping and therefore has three terminals.The voltage between the end terminal and the centre tapping will provide 120V while the voltage between two end terminals will be 220 volts. These Single Phase Pole Mounted transformers can also be used to provide three phase LV supply.
