11kv 33kv Oil Immersed Transformers
This 11kV/33kV oil immersed transformer from Qingdao Hengfengyou Electric Engineering Co., Ltd. is designed for power transmission and distribution, converting network voltage to match system or load requirements. It uses an amorphous alloy core (AMDT) instead of traditional silicon steel, which significantly reduces no-load losses and improves energy efficiency. The fully sealed structure prevents insulating oil and media from atmospheric pollution, allowing operation in humid environments without degradation.
The transformer is built for outdoor power distribution networks, particularly in areas with fluctuating loads or limited maintenance access. Its sealed design extends service life by protecting against moisture ingress, a common failure point in tropical or coastal regions. Typical voltage ratios for this class include 11kV/0.4kV and 33kV/11kV, with cooling provided by natural oil circulation (ONAN) or forced air (ONAF) depending on capacity.
Importers and utility contractors source these units for rural electrification projects, urban grid upgrades, and industrial power substations. Qingdao Hengfengyou Electric Engineering Co., Ltd. supplies from Shandong, China, with packaging and shipping terms to be confirmed directly. Buyers should verify exact kVA ratings, impedance values, and compliance with local grid standards before ordering.
| Voltage Ratio | 11kV / 33kV primary to secondary (exact ratio to confirm) |
| Core Material | Amorphous alloy (AMDT), replacing silicon steel for lower no-load losses |
| Structure | Fully sealed oil-immersed design, prevents atmospheric contamination |
| Cooling Method | Typical: ONAN (Oil Natural Air Natural) or ONAF (Oil Natural Air Forced) |
| Insulating Medium | Mineral oil (standard grade for power transformers) |
| Operating Environment | Suitable for humid and outdoor conditions |
| Typical Capacity Range | Standard for 11kV/33kV class: 100kVA to 10,000kVA |
| Typical Impedance | Standard for distribution transformers: 4% to 6% |
| Typical No-Load Loss Reduction | AMDT core typically offers 60-70% lower losses than silicon steel |
| Typical Compliance | IEC 60076, GB/T 6451 (Chinese national standard) |

Sourcing 11kv 33kv Oil Immersed Transformers from Qingdao Hengfengyou Electric Engineering Co., Ltd. - China Import Guide
Before placing an order for 11kV/33kV oil immersed transformers from Qingdao Hengfengyou Electric Engineering Co., Ltd., verify the exact kVA rating, voltage ratio, impedance, and cooling method required for your project. Request detailed test reports, including routine tests and type tests per IEC 60076 or your local standard. Confirm whether the transformer will be shipped oil-filled or dry, as this affects logistics and customs clearance.
Logistics for power transformers from Qingdao, China, typically involve sea freight in standard containers. Confirm the supplier's FOB Qingdao or CIF pricing, and ask for packing dimensions and gross weight to calculate shipping costs. Lead times for custom-built units can exceed two months, so plan procurement timelines accordingly.
Quality checks should include reviewing factory inspection reports, verifying the amorphous core material specification, and confirming the transformer's compliance with your country's grid interconnection standards. Ask the supplier for references from previous export projects, particularly to regions with similar climate or voltage requirements.
