About Yueqing Heyi Electrical Co., Ltd. - Electric Transformers Supplier in China

China‑based Yueqing Heyi Electrical Co., Ltd. lists 25 active products in its catalogue. All items belong to the electric transformer family, specifically current transformers of various designs such as split‑core, clamp‑on, three‑phase, Rogowski coil and outdoor waterproof models. The product titles include HACT Clamp On Split Core, DM3N1 Series Three Phase, HY 121‑30M‑LA Split Core, and a range of series named ABO, MBO, MES, CP, DM, MSQ, BH‑0.66, RCT, LMK, RLC, SLC, KCT, HK, SCT, DASN, D363, SCT 2851, UK and others. These models are classified under HS chapter 85 for electrical transformers, which is the standard customs heading for current transformers exported from China.

The supplier’s catalogue does not provide individual HS codes, but the collective grouping falls within the 8504.xx sub‑heading used for instrument transformers. Each product is described by its series name rather than detailed specifications, indicating a focus on a broad selection of ratios and mounting styles. The listing includes both indoor and outdoor rated units, suggesting capability to meet diverse installation environments. As an imported supplier with a “harbor” trust tier, Yueqing Heyi positions itself for overseas buyers requiring a variety of current transformer types.

Product Range and Specialties of Yueqing Heyi Electrical Co., Ltd.

The catalogue covers three main construction types: clamp‑on (e.g., HACT Clamp On Split Core), split‑core (e.g., HY 121‑30M‑LA, KCT Series) and wound three‑phase units (e.g., DM3N1 Series, D363). In the transformer industry, current transformers are typically produced to IEC 61869‑2 standards, with accuracy classes of 0.2, 0.5 or 1.0 and burden ratings from 0.5 VA to 20 VA. Primary current ranges commonly span from 0.1 A up to 2 kA, while secondary ratings are usually 5 A or 1 A. Materials include silicon‑steel cores for split‑core types and copper windings, with insulation classes up to 105 °C. Typical variants also include waterproof housings for outdoor deployment and flexible Rogowski coils for non‑intrusive measurements, matching the “Outdoor Waterproof Series” and “Flexible Rogowski Coil” entries in the list.

Trade and Export Information - Yueqing Heyi Electrical Co., Ltd.

China is a leading exporter of instrument transformers, and current transformers from the country are routinely shipped to Europe, North America, Southeast Asia and the Middle East. Buyers in power utilities, industrial automation, railway signaling and renewable‑energy sectors commonly import goods classified under HS 8504.xx, which may require conformity to IEC 61869, CE marking for the European market and RoHS compliance for electronic equipment. Export logistics generally involve 20‑ft or 40‑ft containers, with products packed in anti‑corrosion wooden crates or reinforced cardboard boxes to protect the cores and windings during transit. Common Incoterms used by Chinese manufacturers include FOB Ningbo/Zhoushan ports or CIF destination ports, allowing buyers to arrange inland transport and customs clearance.

Sourcing from Yueqing Heyi Electrical Co., Ltd. - Buyer Guidance

When sourcing from Yueqing Heyi, request the IEC 61869 test report that confirms accuracy class, burden and frequency response for the specific ratio needed. Verify the presence of CE or RoHS certificates if the shipment is destined for the EU or regions with strict hazardous‑substance regulations. Ask for dimensional drawings and mounting details (clamp‑on size, split‑core clearance) to ensure compatibility with existing switchgear or panel boards. Typical minimum order quantities range from a single unit for prototype testing to batches of 50  -  100 for larger projects, with lead times of 15‑30 days after order confirmation, depending on the specific series.
