The silicon steel core used in oil-immersed transformers operates continuously in transformer oil throughout its service life. This operating environment requires excellent heat resistance, aging resistance, and stable magnetic performance.
At Wuxi Zhongpu Electric, we apply strict material control throughout the manufacturing process. We only use genuine grain-oriented silicon steel coils from leading steel manufacturers such as Baowu and Ansteel.
We never use scrap materials and maintain strict control over silicon steel thickness. This helps ensure that every silicon steel sheet maintains stable permeability and low-loss performance during long-term operation in oil and high-temperature conditions.
Wuxi Zhongpu Electric entered the transformer core manufacturing industry in 2000. Over the past 26 years, we have accumulated extensive experience in handling different transformer core requirements.
Our production capacity reaches 1,200 tons per month, allowing us to support large-volume orders with stable delivery capability. We maintain sufficient raw material reserves and efficient production planning to meet customer schedules.
For large-scale projects, our manufacturing capability ensures reliable supply and consistent product quality. Our oil-immersed transformer silicon steel core is developed based on years of professional manufacturing experience.
Automated Shearing for Precision Manufacturing
Our shearing lines are equipped with fully automated CNC systems. This advanced equipment helps us achieve high precision during production and reduces dimensional errors caused by manual operations.
Burr height on each silicon steel sheet is controlled within strict limits. This precision helps reduce eddy current losses and improve the overall performance of the transformer core.
We provide full energy efficiency series coverage from S11 to S22. Our capacity range covers 25kVA to 10000kVA, with voltage ratings up to 110kV.
All products are manufactured according to customer drawings and technical requirements. We produce customized cores instead of maintaining standard stock. Every core is designed specifically for each project.
Strict Inspection and Protective Packaging
Our quality control system combines 100% inspection with batch sampling. Production workers perform self-inspection first. Team leaders then conduct additional checks. Finally, our quality specialists complete final inspections using professional testing equipment.
Before packaging, every core is inspected for dimensions, flatness, and appearance quality.
For transportation, we use rust-proof paper with desiccant protection and reinforced wooden crates for external protection. This packaging method helps prevent moisture damage and impact during shipment.
Our strict manufacturing control and attention to detail help ensure stable quality for every oil-immersed transformer silicon steel core.
