Oil-immersed test transformer advantages and model selection?

Oil-immersed test transformer compared to the same type, its internal winding is identical, the difference is the insulation material or medium is different, dry-type transformer is epoxy resin insulation, the benefit of relatively light weight, but the voltage is limited, the maximum voltage can only be 120kv, in addition to this, epoxy resin is easy to fracture by the impact of the inflatable transformer is insulated with SF6 gas, high precision, Light weight, relatively expensive, generally is the measurement of the hospital, inspection as a standard voltage used, oil-immersed test transformer in addition to heavy is the shortcomings of the other are advantages.

Oil-immersed test transformer using oil as an insulating medium, high voltage, high capacity, metal shell, solid and durable, in the same capacity under the price to be much cheaper, in addition to this, oil-immersed transformer maintenance is cheap and fast, once the line pack failure occurs, only need to screw off the shell, exclude the insulating oil, replace the new line pack into the new oil injection can be compared to the dry-type and inflatable test transformer to be faster! A lot.

Oil-immersed test transformers have more advantages than disadvantages, we do not have special technical requirements when buying and selling, we recommend that you buy oil-immersed test transformers, cheap, solid and durable, it is heavier than the same type of products, but in the case of capacity is not big, the difference in weight is not obvious, such as: 5 kvA.
