We accept telegraphic transfers (T/T), sight letters of credit (L/C) and other flexible payment methods to meet diverse trade requirements and ensure a secure and smooth partnership.
Our products are mainly exported to regions such as Asia, Africa, the Middle East and South America, where they are widely used in power grids, industrial parks and large-scale power projects.
Our 110kV power transformers have obtained ISO 9001, ISO 14001 and IEC standard certifications, as well as national type test reports, and fully comply with international and local grid connection requirements.
Given that 110kV power transformers are large, heavy and customised, we do not provide standard samples. We can, however, provide product catalogues, test reports and factory inspection support.
High-permeability grain-oriented silicon steel sheets are used; the windings utilise high-quality oxygen-free copper; and insulation comprises high-performance insulating paper and environmentally friendly transformer oil, ensuring low losses and high reliability.
We utilise ONAN (natural oil cooling) and OFAF (forced oil-air cooling) systems. In high-temperature regions, the cooling system automatically enhances heat dissipation; in low-temperature environments, low-temperature-resistant transformer oil ensures stable start-up and operation of the equipment.
Standard configurations include pressure relief valve, oil temperature gauge, winding temperature indicator, oil level indicator, sudden pressure relay and other protections to ensure safe and reliable operation.
We implement strict quality control measures, ranging from incoming inspections of raw materials and testing of semi-finished products to final factory testing of finished goods. Professional inspectors are assigned to every stage of the process, and comprehensive records are maintained to ensure consistent and reliable product quality.
Our 110kV transformers undergo a full suite of type tests and routine tests, including no-load loss tests, load loss tests, turns ratio tests, winding resistance tests, induced overvoltage tests, voltage application tests, insulation tests and partial discharge tests.
Yes, we welcome third-party inspection bodies to conduct on-site inspections and witness tests prior to dispatch.
Our transformers utilise advanced manufacturing technologies and strict process controls. The partial discharge level is strictly controlled within an extremely low range, fully complying with IEC standards and power grid operational requirements.
