75 kVA Three Phase Isolation Transformer, 480V to 220V, 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 does RLV compliance mean for a 75 kVA transformer?

At 75 kVA, RLV compliance is particularly relevant for large machine tool installations, industrial automation systems, and commercial building infrastructure, where multiple control circuits are fed from a common isolation transformer rather than individual smaller units. Compliance with RLV regulations is often a mandatory requirement under the EU Machinery Directive, local electrical codes in Australia and the UK, and equivalent regulations across the Asia-Pacific markets.

Q2. How does "lower temperature rise" benefit a 75 kVA installation?

A lower temperature rise means the transformer's windings and core operate at a cooler temperature under full load — extending insulation life, reducing the risk of thermal degradation over time, and allowing the unit to be installed in more confined spaces where heat dissipation is limited. At 75 kVA, even a modest reduction in operating temperature translates to a meaningful extension of service life.
