Import 110kv Three Phase Oil Immersed Transformers — Buy in Bulk from Supplier in China

Qingdao Zhongnuo Steel offers a 110KV three-phase oil-immersed transformer series designed for high-voltage grid applications where power quality, low operational losses, and minimal noise are priorities. The product line has evolved through multiple versions, with current models including configurations for self-cooling, combined air-cooling with maintenance-free operation, and a core suspension-free design for simplified on-site installation. Key performance characteristics are marketed as '1 free, 2 highs, and 4 lows': core suspension-free, high efficiency, high impedance, low loss, low noise, low temperature rise, and low partial discharge.

This transformer range is built to address market demands for extended intervals between overhauls and reliable performance in demanding electrical networks. The oil-immersed design provides effective insulation and cooling for the high-voltage windings and core assembly. While the listing does not detail specific core materials or winding construction methods, typical industry specifications for a 110KV oil-immersed transformer include a core made from grain-oriented silicon steel and windings insulated with quality pressboard and transformer oil.

These transformers are typically procured by power generation companies, electrical utilities, and large industrial facilities for substation projects. The standardized product colony suggests a degree of modular design that may facilitate sourcing and replacement. Specific trade terms such as minimum order quantity, unit pricing, production lead time, and available certifications are not listed and must be confirmed directly with Qingdao Zhongnuo Steel to align with project procurement requirements.

Qingdao Zhongnuo Steel is based at Central International Plaza, Qingdao 266001, Shandong, China. The supplier is assigned a 'harbor' trust tier on the platform, but the current response rate is 0.00%, indicating no recorded history of responding to inquiries. The listing does not provide information about the company's year of establishment, number of employees, or specific manufacturing facility location beyond the city.

The product description positions the company as a supplier of a standardized 110KV transformer product line with multiple configuration options. It highlights performance claims such as low losses and low noise but does not attach specific data sheets, test reports, or third-party certifications to substantiate these claims. Details about the company's quality management system, export history, or key client references are not included in the available information.
