絶縁変圧器とは、電磁誘導によって電気エネルギーを伝達しつつ、一次回路と二次回路を電気的に分離するように設計された変圧器です。一次巻線と二次巻線は電気的に接続されていないため、絶縁変圧器は電圧変換に加えてガルバニック絶縁も実現できます。 絶縁変圧器は、産業機械、CNC装置、病院、データセンター、UPSシステム、自動化装置、実験室、商業ビルなど、電気的絶縁と制御された電力分配が重要な用途で広く使用されています。しかし、すべての絶縁変圧器が同じというわけではありません。 用途に応じて、単相絶縁変圧器、三相絶縁変圧器、乾式絶縁変圧器、樹脂封入型絶縁変圧器、VPI変圧器、[…]などが必要となる場合があります。

Introduction: What Is a Single Phase Power Transformer? A single phase power transformer is an electrical transformer designed to transfer electrical energy between two circuits using electromagnetic induction. It is mainly used in low-voltage and medium-voltage power distribution systems where single-phase loads are required. Compared with three-phase transformers, single phase power transformers are typically used for residential power supply, rural electrification, small commercial facilities, agricultural applications, and distributed power networks. As a professional single phase transformer manufacturer in China, EverNew Transformer provides reliable single phase power transformers with capacities ranging from small distribution units to customized solutions for utility and industrial applications. Our single phase transformers are manufactured according to […]
As the global renewable energy market continues to expand, demand for solar power transformers has grown rapidly. Whether you are an EPC contractor, solar project developer, distributor, or electrical equipment importer, choosing the right transformer supplier is essential for ensuring project reliability, efficiency, and long-term performance. China has become one of the world’s leading manufacturing hubs for power transformers, offering competitive pricing, advanced production capabilities, and international certifications. However, finding the right manufacturer requires more than simply comparing prices. This guide explains how to purchase a solar power transformer from China while avoiding common mistakes and ensuring you receive a high-quality product. Why Buy Solar Power Transformers from China? Many […]
Expert Guide by the EverNew Transformer Engineering Team Selecting a distribution transformer is not a mere procurement transaction; it is a high-stakes, long-term engineering decision that directly dictates system reliability, operational safety, energy efficiency, and total lifecycle costs for the next 30 to 40 years. An optimized choice prevents catastrophic blackouts and minimizes core/copper losses, while an incorrect specification can lead to premature insulation breakdown, localized grid instability, and massive financial penalties. This comprehensive guide is compiled by the senior engineering and design team at EverNew Transformer. The technical insights, selection logics, and empirical data presented below are drawn directly from our real-world project execution across global utility networks, heavy […]
The global electrical infrastructure sector is grappling with an unprecedented supply chain crisis: a severe, structural global transformer shortage. What was historically a straightforward electrical equipment procurement cycle has transformed into a high-stakes bottleneck. Across North America, Europe, the Middle East, and Latin America, delivery timelines for power transformers and liquid-filled distribution transformers have expanded drastically. Lead times that averaged 6 to 12 months before 2020 have skyrocketed, frequently stretching between 24 to 48 months (128 to 160 weeks) for larger units. For EPC contractors, industrial plant developers, renewable energy engineers, and utility companies, this supply delay represents a critical risk to commercial operation dates (COD). Below, we analyze the […]
