Import Amorphous Alloy Transformer — Buy in Bulk from Supplier in China

Shouguang Juneng Electric Co., Ltd. builds the SH15 amorphous alloy transformer with a three-phase, five-column toroidal core of amorphous alloy ribbon, rated for 50 Hz service at voltage ratios of 10/0.4 kV, 11/0.4 kV, and 6/0.4 kV. The unit employs a fully sealed oil-immersed tank with ONAN (oil natural air natural) cooling, keeping insulating oil isolated from ambient air for operation in any environment. Duplex winding construction is used throughout: low-voltage windings are cylindrical copper foil (copper wire on smaller kVA units), while high-voltage windings use multilayer cylindrical construction with wire tensioning and press-formed coils to improve short-circuit withstand.

The amorphous alloy core material exhibits non-crystalline atomic structure, yielding magnetic permeability far above conventional silicon steel. This enables no-load losses around 30% of an equivalent S11 transformer and roughly 75% lower than S9, with no-load current dropping about 80%. Vacuum oil injection raises insulation levels, and the five-limb core geometry produces a lower overall height than conventional three-limb designs. The mounting plate assembly method and balanced ampere-turn distribution reduce magnetic flux leakage and mechanical stress during faults.

These transformers suit urban and rural distribution networks for indoor or outdoor installation, particularly where load cycles include long idle periods and energy recovery justifies capital outlay. Typical buyers include municipal utilities, industrial park developers, renewable energy project integrators, and large facility operators targeting reduced operating expenditure. Delivery is usually within 30 days after deposit, with main body shipped nude and accessories packed in seaworthy wooden cases. Buyers should confirm exact kVA ratings, tap changer details, and protection relay specifications directly with Shouguang Juneng Electric.

Shouguang Juneng Electric Co., Ltd. is headquartered at No. 1757, South Bohai Road, Shouguang, Shandong Province, China, postal code 262700. The company holds ISO9001, ISO14001, and OHSAS18001 certificates according to its listing data. Its trust tier is classified as harbor on the platform, with a response rate of 0.00% and average response hours recorded at zero, which indicates buyers should expect delayed or infrequent communication and plan sourcing timelines accordingly.

The supplier manufactures amorphous alloy distribution transformers under its Juneng brand or with buyer-specified branding, positioning itself in the energy-efficient power equipment segment for Chinese domestic and export markets. Its SH15 series emphasizes the replacement of silicon steel core transformers in grid applications. Beyond the stated product line, the profile offers no disclosed annual revenue, employee count, factory floor area, or named client references, and no specific export volume or country-level experience is verifiable from the source.
