About Chen Pei Enterprise Co., Ltd. - Electric Transformers Supplier in China

China‑based Chen Pei Enterprise Co., Ltd. lists 18 active product entries in its catalogue. All entries belong to the electric transformer component segment and are described as Ferroxcube ferrite cores of various shapes, including C, E, P, T, U, and toroidal formats, as well as iron‑powder toroid cores. The product titles specify core families such as Cores, Epx, PH, EFD, Etd, EQ, Er, PT, Pi, PQ, PM, ER, U, PTS, EI, RM, and separate iron‑powder toroids. The catalogue does not provide HS codes, dimensions, or material grades, but each item is identified as a transformer core component.

The supplier’s catalogue focuses exclusively on magnetic core components used in power conversion equipment. The listed products are manufactured under the Ferroxcube brand and cover both ferrite and iron‑powder technologies, which are typical in high‑frequency and low‑frequency transformer applications respectively. No additional product categories are mentioned beyond these core types. The listing reflects a specialized product line rather than a broad range of transformer assemblies.

Product Range and Specialties of Chen Pei Enterprise Co., Ltd.

Chen Pei Enterprise Co., Ltd. offers a selection of Ferroxcube ferrite cores in standard IEC shapes such as C, E, and toroidal formats, as well as specialized types like PH, PQ, and RM. In the magnetic component industry, ferrite cores are commonly produced from MnZn or NiZn compositions, with typical initial permeability values ranging from 100 to 10,000 and operating frequencies up to several megahertz. Iron‑powder toroids are usually based on iron‑powder composites offering higher saturation flux density and lower core losses at lower frequencies. Buyers often specify dimensions (e.g., outer diameter, inner diameter, height) in millimetres and require compliance with IEC 60184 or IEC 60217 standards for magnetic materials.

Typical grades for ferrite cores include high‑µ (MnZn) for power‑line frequencies and low‑µ (NiZn) for high‑frequency switching. Iron‑powder toroids are graded by particle size and binder content, influencing loss characteristics. Standard packaging for these components includes anti‑static bags or bulk cartons, with each core often supplied in quantities suitable for 20‑ft container loads.

Trade and Export Information - Chen Pei Enterprise Co., Ltd.

China is a leading exporter of magnetic components, and ferrite and iron‑powder cores from the country are routinely shipped to Europe, North America, and Southeast Asia for use in power supplies, automotive electronics, and telecommunications equipment. The relevant HS chapter is 85, where transformer cores typically fall under HS code 8504 (electrical transformers, static converters). Buyers usually request certificates such as ISO 9001 quality management, RoHS compliance, and IEC test reports to verify material purity and performance.

Export logistics for these components often involve containerised shipments with FOB or CIF terms. Cores are packed in moisture‑controlled, anti‑static cartons to prevent corrosion and maintain magnetic properties during transit. Import regulations in major markets may require conformity assessment (e.g., CE marking in the EU or UL listing in the United States) and material safety data sheets for the ferrite composition.

Sourcing from Chen Pei Enterprise Co., Ltd. - Buyer Guidance

When sourcing transformer cores from Chen Pei Enterprise Co., Ltd., request detailed datasheets that list material type (MnZn or NiZn), permeability (µi), saturation flux density (Bs), temperature rating, and dimensional tolerances. Verify that the supplier can provide IEC 60184 test reports or equivalent magnetic property certificates, as well as ISO 9001 and RoHS compliance statements.

Confirm packaging details, such as anti‑static bagging and moisture barriers, especially for bulk orders destined for long‑haul shipping. Ask for sample units to evaluate core loss and dimensional accuracy before committing to full container loads, and clarify lead times, which typically range from 4 to 8 weeks depending on order size and custom specifications.

What types of transformer cores does Chen Pei Enterprise Co., Ltd. offer?

The catalogue lists Ferroxcube ferrite cores in multiple IEC shapes (C, E, P, T, U, etc.) and iron‑powder toroidal cores, each identified by specific product designations such as Cores, Epx, PH, and RM.

Are material specifications like MnZn or NiZn provided?

The supplier’s listing does not include material grades, so buyers should request the exact ferrite composition, permeability range, and saturation flux density in the product datasheet.

Which HS code is applicable to these cores for customs clearance?

Ferrite and iron‑powder transformer cores are generally classified under HS chapter 85, most commonly HS code 8504 for electrical transformers and static converters.

What certifications should a buyer verify before purchase?

Typical certifications include ISO 9001 quality management, RoHS compliance, and IEC test reports for magnetic properties; these should be confirmed with the supplier.

What is the usual minimum order quantity and lead time?

Lead times for magnetic cores are usually 4‑8 weeks, and minimum order quantities depend on core size and packaging but often start at a few hundred units per type for container shipments.

How are the cores packaged for export?

Cores are packed in anti‑static, moisture‑controlled bags or bulk cartons, stacked to protect against mechanical damage and corrosion during sea freight.

Which markets commonly import these Chinese transformer cores?

Major importers include Europe, North America, and Southeast Asian countries, where the cores are used in power electronics, automotive converters, and telecom infrastructure.

Can I request a sample before placing a full order?

Yes, suppliers typically provide sample units with full datasheets and test reports to allow buyers to assess loss characteristics and dimensional accuracy prior to bulk purchasing.
