About Shandong Genshen Electric Co., Ltd. - Electric Transformers Supplier in China

Shandong Genshen Electric Co., Ltd. is based in China and currently lists five active transformer products. The catalogue includes Power/Distribution Transformer, Oil Power/Distribution Transformer, Electrical Distribution Transformers, S11 series 20 kV 200 kVA Distribution Transformer, and High Voltage Oil Immersed Transformer. These items fall under the electric transformer category and are identified with the supplier’s trust tier of “harbor”. The product titles indicate a focus on both dry‑type and oil‑immersed designs for distribution and high‑voltage applications.

The listed products cover voltage classes from medium voltage (20 kV) up to high‑voltage oil‑immersed units, with apparent power ratings ranging from unspecified lower levels to 200 kVA as noted for the S11 series. The naming suggests compliance with typical industry classifications such as distribution transformers for grid step‑down and high‑voltage power transformers for transmission support. No additional categories beyond electric transformers are detailed in the provided data.

Product Range and Specialties of Shandong Genshen Electric Co., Ltd.

The supplier’s catalogue comprises five transformer models: a generic Power/Distribution Transformer, an Oil Power/Distribution Transformer, a line labeled Electrical Distribution Transformers, the S11 series 20 kV 200 kVA Distribution Transformer, and a High Voltage Oil Immersed Transformer. These represent both dry‑type and oil‑filled constructions, covering medium‑voltage distribution and higher voltage transmission needs.

In the transformer market, dry‑type distribution units are typically rated up to 35 kV and conform to IEC 60076‑2 specifications, with insulation classes ranging from Class A to Class F. Oil‑immersed transformers for high voltage usually meet IEC 60076‑3, featuring oil dielectric strength of at least 35 kV and temperature‑rise limits of 55 °C for 65 % load. Common performance grades include efficiency classes (e.g., IEC 60214) and load‑loss percentages below 2 % for 200 kVA units. Buyers often request test reports such as routine type tests, temperature‑rise, and dielectric tests.

Trade and Export Information - Shandong Genshen Electric Co., Ltd.

China is a major exporter of electric transformers, supplying equipment to Southeast Asian grids, African utility projects, and European industrial facilities. Export shipments are typically loaded in 20‑ft or 40‑ft containers for smaller dry‑type units, while larger oil‑immersed transformers are shipped as break‑bulk cargo on flat‑rack trucks or containerized pallets with reinforced bracing.

Importing parties usually require compliance with IEC standards, CE marking for European markets, and UL certification for North America. Documentation commonly includes a test certificate, a declaration of conformity, and a factory inspection report. Depending on the destination, customs may request a material safety data sheet for the insulating oil and proof of compliance with REACH or RoHS directives. Standard Incoterms such as FOB Shanghai or CIF Hong Kong are frequently used for transformer transactions.

Sourcing from Shandong Genshen Electric Co., Ltd. - Buyer Guidance

When sourcing transformers from this supplier, buyers should request the latest IEC type test report, a detailed specification sheet stating voltage class, rated power, impedance voltage, and cooling class (e.g., ONAN, ONAF). Verification of oil quality, including moisture content below 10 ppm and dielectric strength above 35 kV, is essential for oil‑immersed models.

Samples of smaller dry‑type units can be evaluated for no‑load loss and temperature rise under standard test conditions. For larger units, buyers often ask for a factory‑made prototype or a 3‑D model to assess dimensions and mounting provisions. Confirming the supplier’s ISO 9001 certification or equivalent quality‑management system, as well as reviewing recent factory audit reports, helps mitigate risk before placing a bulk order.

What voltage classes are covered by the listed transformer models?

The catalogue mentions a 20 kV rating for the S11 series and a generic high‑voltage oil‑immersed transformer, indicating coverage from medium‑voltage (approximately 10‑35 kV) up to high‑voltage classes above 35 kV.

Do the transformers meet international standards?

While specific certifications are not listed, transformers of this type are normally designed to IEC 60076 series standards for construction, testing, and performance.

What documentation should a buyer request before shipment?

Typical documents include an IEC type test certificate, a declaration of conformity, a material safety data sheet for the insulating oil, and a quality‑management system certificate such as ISO 9001.

What are common minimum order quantities and lead times for these products?

For medium‑size dry‑type units, minimum orders often start at one unit, with lead times of 6‑8 weeks. Larger oil‑immersed transformers may require a minimum order of a single unit as well, with lead times extending to 12‑16 weeks depending on customization.

How are the transformers packaged for export?

Dry‑type units are usually crated in wooden boxes with internal dunnage and loaded in standard containers. Oil‑immersed units are typically secured on reinforced pallets, wrapped with steel straps, and either containerized or shipped as break‑bulk cargo with protective skidding.

Which certifications are typically required by buyers of Chinese‑made transformers?

Buyers commonly require IEC compliance, CE marking for EU destinations, UL listing for North America, and evidence of ISO 9001 quality‑management certification. Environmental compliance such as REACH or RoHS may also be requested for the oil and ancillary materials.

Can samples be provided for the dry‑type distribution transformer?

Suppliers often supply a low‑power sample or a prototype unit for performance testing, allowing verification of no‑load loss, temperature rise, and impedance characteristics before a full order.

What cooling methods are used in the oil‑immersed transformer models?

Oil‑immersed transformers typically employ natural oil circulation (ONAN) or oil‑forced and air‑forced (ONAF) cooling, depending on the rating and design. The specific cooling class is usually indicated in the technical data sheet.
