CHBEB (Beierbian Group Co., Ltd), established in 1958, is a manufacturer specializing in power and distribution transformers. Its product range includes oil-filled, dry-type, pole-mounted and pad-mounted transformers, as well as compact substations for industrial distribution, utilities, renewable energy, data centers, and EPC projects.
CHBEB operates multiple production facilities with capabilities covering core processing, coil winding, vacuum drying, assembly, and final testing. The company supports OEM and ODM services and can customize capacity, voltage, frequency, cooling method, materials, enclosure structure, and installation configuration according to project requirements.
CHBEB presents ISO 9001, ISO 14001, ISO 45001, CCC, and CE certification materials, while its products can be designed to meet IEC, IEEE, ANSI, and GOST-R requirements. Published lead times are approximately 1–3 months during the off-season and 3–6 months during the peak season, although standard transformer orders may be completed in about 30 days. Actual schedules depend on product specifications, design complexity, order quantity, material availability, drawing approval, testing, and shipping arrangements. Buyers should therefore confirm the production schedule and delivery date for each order before finalizing the purchase.
