American prefabricated substations is based on urban and rural power grid construction and development and transformation of the needs of the development of a series of products. It is the transformer body, switchgear, fuses, tap-changers, low-voltage power distribution equipment and other auxiliary equipment for the combination of transformer, to meet the user energy metering, reactive power compensation, low voltage shunt and other preparation requirements. ZGS-type modular transformer as AC 50Hz, 6 ~ 10kV network, rated capacity of 63 ~ 1600kVA independent set of power distribution equipment, both for outdoor use, can also be used indoors. Widely used in industrial parks, urban residential areas, commercial centers, high-rise buildings and temporary construction sites and other places.
Dry type transformers shall be installed in accordance with the manufacturer's requirements, and shall be equipped with temperature measuring devices, generally 630kVA and above transformers. A,1000kVA and above oil-immersed transformer shall be equipped with an outdoor signal thermometer and can take distant signals. Product features: A, tank using corrugated sheet, it has the respiratory function to compensate for temperature change caused by the oil volume change, so the product without oil storage tank, obviously reduce the height of the transformer. B, because the corrugated film replaces the storage tank, the transformer oil is isolated from the outside, thus effectively preventing the entry of oxygen and water and the decrease of insulation performance. C, according to the above five performance, to ensure the oil-immersed transformer within the normal operation of the don't need an oil change, greatly reduces the maintenance cost of transformer, and prolong the service life of the transformer. D. In addition to the small capacity of copper wire, copper foil is usually used in the cylinder structure. The high voltage winding adopts multi-layer cylindrical structure to balance the ampere-turns distribution of the winding, the leakage is small, the mechanical strength is high, and the anti-short circuit capability is strong. E, iron core and winding each adopt the fastening measure, the height of the device, the low voltage lead wire and other fastening parts are equipped with self-locking anti-loose nuts, adopt the non-lifting structure, can withstand the shock of transportation. F, coil and iron core adopt vacuum drying, the transformer oil adopts vacuum filter oil and oil filling process, which minimizes the moisture in the transformer.

The KCT range of split core current transformers have been specifically designed to be small CT and easy to open and yet maintain the accuracy required for kwh meters. The benefit of a split core current transformer is that it can be placed into position easily and without disturbing or disconnecting the main cables it is monitoring. The KCT range of current transformers has two insulated terminal covers for connecting the S1 and S2 cables which lock down over the terminal screws fully insulating the connections. This makes it ideal to use Autometers cable hamesses which are colour coded and individually numbered on each conductor ensuring simple and easy connection from the current transformer to the electricity meter.
