Although 750 kva 3 phase dry type transformers exhibit excellent technical performance in various aspects, their relatively high cost and considerations related to capital investment make them unsuitable for all situations.750 kva 3 phase dry type distribution transformers are primarily used in the following scenarios where750 kva 3 phase oilimmersed distribution transformers may not be the preferred choice:
In places with high fire safety requirements and densely populated important buildings (such as subways, high-rise buildings, theaters, shopping malls, airport terminals, etc.) and in oil-free distribution equipment within industrial facilities (such as power plants, steel mills, petrochemical plants), 750 kva 3 phase dry type distribution transformers should be selected according to design specifications.
When the available space is limited and the technical and economic indicators are reasonable,750 kva 3 phase dry type distribution transformers are a suitable choice.
Considering the initial investment, as well as the additional costs associated with750 kva 3 phase oil immersed power transformers, such as oil drainage facilities, explosion-proof barriers, waste oil disposal, operation, maintenance, and losses,750 kva 3 phase dry type distribution transformers may be chosen when deemed economically feasible through technical and economic comparisons.
Distribution substations that are integrated with residential buildings or lack independent transformer rooms are better suited for750 kva 3 phase dry type distribution transformers.
Locations where it is difficult to address environmental pollution caused by oil spill accidents with750 kva 3 phaseoilimmersed power transformers may opt for750 kva 3 phase dry type distribution transformers.
In outdoor box-type substations located too close to important buildings, where fire safety clearance is insufficient,750 kva 3 phase dry type distribution transformers can be a suitable choice.
