はじめに
A 30kVA transformer is a compact and reliable power distribution unit designed for low to medium voltage applications. Whether used in residential complexes, small commercial spaces, or light industrial systems, it ensures efficient voltage transformation while maintaining power stability and safety.
Understanding the 30kVA transformer price and its influencing factors can help businesses and engineers make cost-effective decisions. In this article, we’ll explore product features, pricing, technical data, and real-world applications of 30kVA transformers in the context of modern electrical systems.
What Is a 30kVA Transformer?
A 30 kilovolt-ampere (kVA) transformer is an electrical device designed to convert voltage between different levels while maintaining the same frequency. It can step up or step down voltage and is available in multiple configurations such as:
- Oil-immersed type
- Dry-type (cast resin)
- Pole-mounted
- Pad-mounted
These transformers are part of the broader category of phase transformers and are available in both single-phase そして three-phase formats, depending on your project needs.
