About Yueqing Top Electric Science Co., Ltd. - Industrial Machinery Supplier in China

Yueqing Top Electric Science Co., Ltd. is based in China and lists 17 active products across five top categories: Industrial Machinery, Electric Components, Capacitors, Electric Insulators and Cable Assemblies. The catalogue includes items such as contact boxes, capacitors, cable bushings, busbar bushings and a series of APG‑technology clamping and mixing machines. Each product is identified with its corresponding HS‑code where available, for example the 12kV 148x250 Contact Box Campana is recorded under HS code 8538.90 and the 35kV Capacitor under HS code 8532.29. The supplier also offers several models of automatic moulding and mixing equipment that are not assigned HS codes in the provided data. The listed items combine epoxy resin (often described as APG grade) with silicone powder fillers, copper conductors or ceramic/polypropylene dielectrics, reflecting typical material choices for high‑voltage insulation and capacitor construction. Products such as the 24kV 3000A Contact Box Campana (HS 8536.50) and the 24kV125pF Capacitor for Epoxy Resin Insulators (HS 8532.29) illustrate the voltage range covered, from 12 kV up to 35 kV, and the use of silver‑aluminum electrodes in certain capacitor housings. The catalogue therefore spans both finished electrical hardware and the specialised machinery used to produce epoxy‑based components.

Product Range and Specialties of Yueqing Top Electric Science Co., Ltd.

The product catalogue contains high‑voltage contact boxes (12 kV, 24 kV, 27 kV), cable and busbar bushings, and capacitors ranging from 12 kV to 35 kV. In the capacitor segment, buyers typically encounter ceramic or polypropylene dielectrics encapsulated in epoxy resin, with voltage ratings expressed in kilovolts and capacitance values such as 125 pF. Standard industry grades for such capacitors follow IEC 60384 specifications, including tolerance ±5 % and leakage current limits defined per voltage class. Industrial machinery items include the TEZ‑ series automatic clamping and moulding machines, as well as mixers designed for APG epoxy resin processing. These machines are generally rated by moulding capacity (e.g., cavity size in mm), heating power (kW) and cycle time (seconds). Buyers of such equipment often compare spindle speeds, precision tolerances (±0.1 mm) and control system types (PLC vs. CNC).

Trade and Export Information - Yueqing Top Electric Science Co., Ltd.

China is a major exporter of high‑voltage electrical hardware and related manufacturing equipment. Products classified under HS 8538, 8532 and 8536 are routinely shipped to buyers in Southeast Asia, the Middle East, Europe and North America, where utilities and industrial plants require reliable insulation and switching devices. Typical certifications requested by importers include IEC compliance, ISO 9001 quality management and, where applicable, CE marking for the European market. Capacitors and contact boxes are usually packed in wooden crates or metal drums with moisture‑absorbing liners, and shipped in 20‑ft or 40‑ft containers using FOB or CIF terms. Chinese export regulations require a customs declaration with the correct HS code and, for epoxy‑based components, a Material Safety Data Sheet (MSDS) accompanying the shipment. Inspection agencies often perform pre‑shipment verification according to the IEC 61850 standard for high‑voltage equipment.

Sourcing from Yueqing Top Electric Science Co., Ltd. - Buyer Guidance

When sourcing from this supplier, buyers should request the latest IEC test reports for voltage withstand, insulation resistance and dielectric loss for each capacitor model. For contact boxes and bushings, a UL or IEC 60947 conformity certificate should be verified, along with dimensional drawings that show terminal spacing and enclosure IP rating. Sample requests should specify the epoxy resin grade (APG) and any filler percentages, as these affect thermal conductivity and mechanical strength. Buyers are advised to confirm the machine specifications (e.g., mould cavity dimensions, heating capacity) against their production requirements, and to obtain a factory acceptance test (FAT) report before final acceptance. Verifying the presence of an up‑to‑date ISO 9001 certificate can further assure consistent manufacturing processes.

What voltage ratings are available for the contact boxes listed by Yueqing Top Electric Science?

The catalogue includes contact boxes rated at 12 kV, 24 kV and 27 kV, with current capacities such as 630 A for the 24 kV CH3‑24‑185 model and 3000 A for the 24 kV 3000A version.

Which HS codes apply to the capacitors offered by the supplier?

Capacitors are recorded under HS 8532.10 for the 12 kV 125 pF type and HS 8532.29 for the 35 kV and 24 kV 125 pF types. The codes correspond to capacitors of fixed capacitance and high‑voltage types.

What materials are used in the epoxy resin insulators?

The insulators are described as epoxy resin (APG grade) combined with silicone powder filler and, where noted, hardener. Some models also incorporate copper conductors or ceramic dielectrics within the housing.

Are there any standard certifications buyers should ask for?

Buyers should request IEC compliance certificates (e.g., IEC 60384 for capacitors, IEC 60947 for contact boxes), ISO 9001 quality management certification, and, for European shipments, CE marking documentation.

What typical packaging is used for the high‑voltage components?

High‑voltage components are usually packed in wooden crates or metal drums with moisture‑absorbing liners, sealed with anti‑static film, and labeled with the appropriate HS code for customs clearance.

What are the typical lead times for the TEZ‑ series clamping machines?

Lead times for the TEZ‑ series moulding and clamping equipment generally range from 30 to 60 days from order confirmation, depending on configuration and any required custom tooling.

How can a buyer verify the performance of the 12 kV Capacitor?

Performance verification should include IEC 60384 test reports covering voltage withstand, capacitance tolerance, dissipation factor and leakage current at the rated voltage.

What documentation accompanies the cable bushings?

Cable bushings are shipped with an MSDS for the epoxy resin, a dimensional drawing, and a test report confirming dielectric strength and insulation resistance per IEC 60384.
