About Shen Zhen Chuang Yin Technology Co., Ltd. - Electric Transformers Supplier in China

China‑based Shen Zhen Chuang Yin Technology Co., Ltd. lists five distinct transformer products in its catalogue. The active product count of five covers split‑core and clamp‑on current transformers, a flexible Rogowski coil, and both voltage and current transformers rated at 11 kV. All items fall under HS chapter 8504, which classifies electrical transformers, static converters and inductors for export and import reporting. The catalogue specifies a Split Core Current Transformer rated 6000 A/333 mV, a Clamp‑On Current Transformer rated 500 A, a Flexible Rogowski Coil Current Transformer, an 11 kV Voltage Transformer (PT) and an 11 kV Current Transformer. These products are typical of the IEC 61869 family of instrument transformers, where accuracy classes, burden ratings and insulation levels are defined by international standards rather than by the supplier’s own claims.

Product Range and Specialties of Shen Zhen Chuang Yin Technology Co., Ltd.

The five products listed by Shen Zhen Chuang Yin Technology Co., Ltd. represent common instrument‑transformer types used for metering and protection. Split‑core and clamp‑on current transformers are normally supplied in accuracy classes 0.2, 0.5 or 1.0 with a burden of 1 - 5 VA, while 11 kV voltage and current transformers often meet class 0.2 or 0.5 and are insulated for a maximum continuous voltage of 33 kV. Industry practice for Rogowski coils includes a frequency response up to 200 kHz, a typical sensitivity of 1 V/A and a flexible, non‑magnetic winding that allows installation on irregular conductors. Buyers generally expect IEC 61869‑2 compliance, RoHS conformity for lead‑free construction, and, for export from China, CE marking where the end market requires it.

Trade and Export Information - Shen Zhen Chuang Yin Technology Co., Ltd.

China is a leading exporter of instrument transformers, with the majority of shipments destined for Southeast Asian utilities, European grid operators and North American industrial customers. HS code 8504.31 covers power transformers and 8504.32 covers other transformers, both of which are used for the products in this catalogue. Typical certifications requested by overseas importers include IEC 61869 test reports, RoHS compliance certificates and, where applicable, CE or UL listings. Export logistics from China usually involve wooden crates or bulk pallets packed in 20‑ft or 40‑ft containers, with freight terms such as FOB Shanghai or CIF destination port. Customs inspections often verify the HS code, country of origin labeling and conformity to safety standards before release.

Sourcing from Shen Zhen Chuang Yin Technology Co., Ltd. - Buyer Guidance

Buyers should request an IEC 61869 test report that details accuracy class, burden, rated primary current and insulation level for each transformer. Calibration certificates dated within the last 12 months provide additional assurance of performance. It is advisable to confirm the product’s mounting dimensions, terminal type (screw, bolt‑on or welded), and protective enclosure rating (IP 20‑IP 54) before placing an order. For Rogowski coils, ask for the frequency response curve and the output voltage per ampere specification. Samples or pre‑production units are commonly accepted for validation of fit‑and‑function.

What accuracy classes are available for the split‑core and clamp‑on current transformers?

Typical offerings are class 0.2, 0.5 or 1.0 as defined by IEC 61869‑2, with a burden of 1 - 5 VA. The exact class should be confirmed on the test report.

Does the supplier provide IEC 61869 certification for the 11 kV transformers?

The supplier can supply IEC 61869 test reports on request. Buyers should verify the report covers accuracy, insulation level and temperature rise.

What is the standard packaging for these transformers when shipped internationally?

Transformers are usually packed in wooden crates with internal cushioning, loaded into 20‑ft or 40‑ft containers. The packaging meets ISPM 15 wood‑pest standards for export.

Are RoHS or other environmental certifications available?

RoHS compliance can be provided as a declaration of conformity. Additional certifications such as CE or UL depend on the target market and should be requested.

What are typical minimum order quantities and lead times?

MOQ varies by product but generally starts at one unit for sampling, with production lead times of 4 - 6 weeks for larger batches after final specifications are approved.

How should a buyer request a sample of the flexible Rogowski coil?

Buyers can request a single‑unit sample, specifying the required length, frequency response and output voltage per ampere. Shipping is usually via air freight for rapid evaluation.

Which HS codes should be used for customs clearance of these items?

Customs filings normally use HS 8504.31 for power transformers and HS 8504.32 for other instrument transformers, including current and voltage transformers.

What documentation is needed to clear customs in Europe or North America?

A commercial invoice, packing list, IEC 61869 test report, and any required CE or UL certificates are standard. Importers should also ensure the correct HS code and country of origin marking.
