60 kVA Three Phase Isolation Transformer, 190V to 400V, Step Up/Down

Note:

1. The transformer can only convert voltage, and CANNOT convert frequency.
2. The transformer CANNOT convert 1-phase voltage to 3-phase voltage.
3. Input/output voltage, power rating, and whether a shell for all transformers can be customized to meet clients' requirements.

Q1. What distinguishes the 60 kVA unit from smaller ratings in this transformer series?

At 60 kVA, this transformer enters a capacity range suited for supplying entire production sections, building distribution sub-panels, or multiple machines simultaneously — rather than individual equipment point connections typical of smaller ratings. The unit weight (268 kg aluminium open type, up to 345 kg copper protected type) and physical footprint reflect this scale, and optional movable wheels become practically important for positioning during installation. High-grade component selection and the latest manufacturing technology are particularly relevant at this capacity, where the consequences of premature failure or degraded insulation are significantly greater than at sub-20 kVA ratings.

Q2. What does "maintenance-free working" mean in practice for a 60 kVA transformer?

Maintenance-free refers to the dry-type, air self-cooling construction — the transformer contains no insulating oil and requires no external cooling equipment. Unlike oil-filled transformers, there is no oil to sample, test, top up, or replace over the unit's service life. Routine care is limited to periodic visual inspection of the enclosure, terminal connections, and ventilation clearances. This significantly reduces the total cost of ownership at the 60 kVA scale compared with oil-cooled alternatives, and removes the need for oil containment infrastructure, specialist maintenance contracts, or scheduled outages for fluid servicing.
