Farady oil immersed transformer features

Farady can design and manufacture oil immersed transformer with voltage up to 220KV and capacity up to 100MVA according to IEC standard, This series of oil immersed transformer have following features: low loss,low temperature rise and low partial discharge, high reliability, core lifting free,no leakage. Farady oil immersed power transformer is advanced insulation temperature control technique, special insulation material are used in hot-spot of the winding and transformer body.

The structure of Farady transformer

For distribution transformer, insulation and cooling conditions according to points, can be divided into oil immersed transformers and dry type transformers. In order to strengthen the insulation and cooling conditions, the transformer core and windings are together immersed in a tank filled with transformer oil in. In exceptional cases, such as street lights, mine illumination, but also with dry-type transformers. In addition, there are a variety of special-purpose special transformers.

Oil immersed transformer classification

Oil immersed transformers 1000kVA and above, shall be installed outdoor thermometer type signal, and then the distant signal. 800kVA and above should be installed oil-immersed transformer gas relay and pressure protection device, 800kVA transformer oil-immersed according to the following requirements, in consultation with the manufacturer, but also can be equipped with gas relay. Dry-type transformers shall be specified by the manufacturer, the installation of a temperature measuring device, and more generally for the 630kVA transformer installations. Products classified according to the number of phases to distinguish between single transformer can be divided into three-phase transformers and single phase transformer. In a three-phase power system, the general application of the three-phase transformer, when the oversized transport conditions and subject to the three-phase power system can also be applied consisting of three single-phase transformer transformer group.

Oil Immersed Transformers are mostly used for outside applications

Because of safety reason and the flammability of the oil in the oil type transformer,oil immersed transformers are mostly used for outside applications. Farady oil immersed distribution transformers are suitable in case of external installations or in the most heavy industrial areas. The transformers are filled with mineral oil free from PCB and PCT. The oil tank is realized to allow the oil expansion during the normal heating and cooling phases of transformer due to load cycles, or by a radiators system. It is also possible to produce transformers in the version with oil conservator or the hermetic type.

Farady power and distribution transformer manufacturer

We manufacture Outdoor/indoor oil immersed distribution transformer without top expansion tank upto 33kv substation system voltage. This design has a single tank. The core and windings are contained in the lower tank. The primary winding is taken through the HT insulator to be connected to the primary terminal arranged at the top of the HT insulator. The secondary windings are connected to secondary terminals placed on the lower tank.

Farady power transformer

Farady power transformer manufacturer present the largest portion of the capital investment in addition the power transformer remains oil immersed power transformer which presents a fire hazard that is particularly objectionable in urban and metropolitan environment. After careful studies of various alternatives to conventional transformer technology to produce a gas insulated power transformer with increased mega volt-ampere ratings, gas insulated power transformer has been developed with a use with non flammable gas. For changing the insulating material from oil to gas a comparative study between these types of transformers should be made. In this paper two mathematical models are suggested and simulated by computer programs to calculate the temperature of the cooling mediums and transformer windings.

Farady Amorphous oil-immersed transformer

Widely replacing the silicon steel core transformer by amorphous alloy core oil immersed transformer in outdoor power distribution system, then we can get the desirability of good energy saving effect and reduce the pollution of the atmosphere. Farady Amorphous Core Transformer commonly use sealed structure, so insulated oils and dielectric are not affected by air pollution, which can be run in a damp environment. In this case, it is ideal equipment for distribution in urban and rural general distribution network, especially suitable for low power, load fluctuations and the area which is difficult to carry out routine maintenance.

Farady distribution transformer with Conservator

Farady distribution transformer has a power range of 6.3-2500kVA, and it suits for 10KV, 50/60Hz power transmission and distribution systems. The Farady oil immersed transformer is often accepted for 6KV and 10KV power transmission and distribution systems, the high voltage auto load booster shows lowered no-load loss and reduced no-load current, thus realizing notable energy saving performance. Moreover, the noise level meets relevant requirements of environmental protection policy. So, this is an energy saving and environmental friendly product.
