Three Phase Outdoor Power Distribution Transformer

China Three Phase Outdoor Power Distribution Transformer manufacturers – high-quality OEM/ODM suppliers with competitive pricing!The outdoor distribution transformer is a type of three-phase transformer that converts high-voltage electrical energy into low-voltage electrical energy and is suitable for outdoor installation. Three Phase Outdoor Power Distribution Transformer is usually composed of components such as a core, windings, insulating materials, an oil tank (or casing), and a heat sink, and is capable of withstanding harsh conditions in outdoor environments such as wind, rain, sunlight, and dust, ensuring the stable operation of the power system.

Product Description

Characteristics

Three Phase Outdoor Power Distribution Transformer features waterproof, dustproof and corrosion-resistant properties, enabling it to operate stably for a long time in harsh outdoor environments. It also adopts special designs, such as waterproof enclosures and materials like stainless steel or galvanized zinc plates, further enhancing its protective capabilities. It uses high-magnetic-conductivity silicon steel sheets and low-loss windings made of high-quality materials to reduce transformer losses and improve operational efficiency. It has excellent insulation performance and mechanical strength, ensuring the safety and stability of the transformer during outdoor operation. Three Phase Outdoor Power Distribution Transformer is equipped with safety devices such as overload protection and short-circuit protection to prevent damage to the transformer or accidents in abnormal situations. It also adopts an isolated design to achieve electrical isolation between input and output terminals, effectively suppressing grid harmonics and surges, and protecting sensitive equipment.

1. What specifications of oil-immersed transformers are available for selection? Can they be customized?

We offer a full range of Three Phase Outdoor Power Distribution Transformer with rated capacities ranging from 100 kVA to 5000 kVA. The input voltages are 6 kV/10 kV/11 kV/15 kV/20 kV/22 kV, and the output voltages are 380 V/400 V/415 V. The working frequency is 50 Hz/60 Hz. This ensures stable quality and safe operation performance globally. The cores are made of high-quality CRGO silicon steel sheets, and the windings can be customized with copper or aluminum materials according to your requirements. We support full customization (OEM/ODM) based on your drawings, voltage, capacity, and application scenarios (such as industry, power grid, mining), and provide professional R&D teams to offer technical solutions.

2. What certifications do your oil-immersed transformers have? Do they comply with international standards?

All our transformers have passed ISO and CE certifications and strictly comply with IEC, EN international standards, ensuring stable quality and safe operation performance in the global market. Each product undergoes strict factory acceptance tests (FAT) before delivery, including insulation resistance tests (≥500 MΩ), electrical strength tests (35000 V/1 minute without breakdown), and oil quality tests, and complete test reports will be provided for you for customs clearance and inspection.

3. What is the minimum order quantity, delivery time, and transportation method?

The minimum order quantity is 1 set, suitable for small batch trial orders and large-scale purchases. The delivery time is 15 to 30 working days. Our monthly supply is 200 sets to ensure on-time delivery (100% on-time delivery rate). The transportation methods include sea freight, air freight, or land transportation from ports in Shanghai, Shenzhen, or Changsha. We cooperate with professional logistics companies to provide door-to-door services, customs clearance assistance, and real-time logistics tracking services.

4. How do we solve common faults during use (such as oil leakage, overheating)?

Our transformers adopt high-quality sealing components (nitrile rubber gaskets) and advanced welding technology to minimize the risk of oil leakage. If you encounter common faults: ① Oil leakage: Locate the leakage point (flange, valve, weld seam), replace the sealing gasket or repair with epoxy resin; ② Overheating: Reduce the load, clean the radiator, or check the cooling fan; ③ Abnormal noise: Tighten the core bolts or clean the bearing dirt. We provide detailed maintenance manuals, and our 24-hour online technical team will provide real-time guidance - avoiding your factory from experiencing expensive downtime.

5. Are you a manufacturer or a trader? Can I visit your factory?

We are a professional manufacturer of oil-immersed transformers with over 20 years of R&D and production experience. We have modern calibration equipment and a professional technical team. We are not a trader - therefore, we can offer factory direct sales prices and customization services without middleman markup. Our factory is located in Wenzhou, Zhejiang Province. We warmly welcome you to visit. We will arrange professionals to receive you, show you the production line, and conduct on-site product testing.
