Import 50kva Industrial Power Control Transformer — Buy in wholesale FOB from Supplier in China

The 50KVA Industrial Power Control Transformer from Aiia Transformer is a three-phase unit designed for industrial power distribution and machinery control applications, rated at 50 kVA capacity with dual frequency operation at 50 Hz and 60 Hz. The transformer incorporates thermal management systems and built-in protection against overload and short circuit conditions, targeting continuous-duty industrial environments. Insulation resistance and noise level performance are cited as design priorities, though specific test values and dB(A) ratings are not provided in the source material. The unit is manufactured in Dezhou, Shandong Province, a region with established metalworking and electrical equipment manufacturing infrastructure.

Industrial control transformers at this rating typically employ copper or aluminium windings with class F (155 degrees C) or class H (180 degrees C) insulation systems, depending on application temperature rise requirements and cost constraints. The core construction is generally laminated grain-oriented silicon steel, with three-limb or five-limb configurations selected based on harmonic content and zero-sequence performance needs. Standard practice for 50 kVA three-phase units includes vector group Dyn11 or Yyn0, with typical impedance values of 4-6% to limit fault current and provide adequate voltage regulation under load. The dual 50/60 Hz capability indicates a core design flux density selected to avoid saturation at the higher frequency, which implies slightly lower flux density at 50 Hz than frequency-specific designs might employ.

Buyer segments include manufacturing facilities, construction contractors for temporary power installations, and energy sector operations requiring reliable control voltage supplies for automation systems, lighting circuits, and auxiliary equipment. The transformer suits applications where galvanic isolation, voltage step-down, or phase conversion is required between medium voltage distribution and low voltage utilisation systems. Specific pricing, MOQ, lead time, and exact dimensions are not stated in the listing; these must be confirmed directly with Aiia Transformer. The source mentions FOB and CIF as available shipping terms, though negotiation details and port of loading require clarification.

Aiia Transformer operates from Jintian Pioneering Park, Tianqu Industrial Park, No. 7 Ge Ruide Road, Dezhou, Shandong Province, China. Dezhou sits within Shandong's northern industrial corridor, with established logistics connections to Qingdao port and Beijing-Tianjin economic zone. The supplier holds a harbor trust tier on the platform. The response rate is recorded at 0.00% with zero average response hours, which suggests that platform-mediated communication may not be reliable; buyers should seek direct contact channels through the company's registered address or known trade fair presence.

The company profile does not disclose founding date, factory area, number of employees, annual production capacity, revenue figures, or specific client installations. No ISO 9001, ISO 14001, or product certifications such as CE marking or UL listing are mentioned in the available data. The product range appears to include industrial power control transformers, though the full catalogue scope and whether the company manufactures or sources the 50 kVA unit are unclear. Buyers should request a factory audit, quality management system documentation, and witness test reports for identical or similar-rated units before committing to volume orders.
