10 20 25kva~150kva 120V~240v Single-phase Series Oil-immersed Distribution Transformer

 

 

Robust 10 - 150kVA Single-Phase Oil-Immersed Transformers (120V / 240V Input/Output)

Engineered for demanding applications, our single-phase oil-immersed transformer series delivers reliable power conversion in the critical 10kVA to 150kVA range. Designed with a focus on durability and efficiency, these transformers accept standard 120V or 240V input and provide stable, isolated 120V/240V output – making them ideal for residential, commercial, and light industrial power distribution, equipment isolation, and voltage stabilization.

After the production and manufacturing of products (transformers, as shown in the picture) are completed, they enter the testing process. First, the products are placed in a professional testing center. Technicians use control panels and relevant equipment to conduct comprehensive tests. This includes checking electrical performance, insulation strength, and other indicators. Some products may undergo simulated operation tests to ensure stable operation under different working conditions. During the test, data is carefully recorded and analyzed. If any problems are found, adjustments and retests will be carried out until all performance indicators meet the standards, ensuring that the products delivered are of high quality and reliable.

Tom Davis, a project manager at a local power engineering company in Australia, needed reliable single-phase series oil-immersed distribution transformers for a critical power project in April 2019. After extensive searching and comparisons, he came across an industry-specific site where he discovered Jinshanmen Technology Co., Ltd.'s range of 10 - 150kVA 120V - 240V single-phase series oil-immersed distribution transformers.

Impressed by the detailed parameters and features, particularly noting Jinshanmen Technology's 30 years of expertise in manufacturing various transformers, and its location in the scenic city of Lishui, Zhejiang Province, China, Tom reached out to Jinshanmen Technology via the contact information provided on the website.

Jinshanmen Technology's sales team promptly responded to Tom's inquiry, warmly introducing the product's advantages and providing some real-world application cases. Tom was impressed with the professionalism and efficiency of the team. Subsequent phone calls and technical exchanges revealed that Jinshanmen Technology not only offered reliable products but also excellent customer service, including the ability to customize products to meet specific project requirements.

After careful consideration, Tom decided to collaborate with Jinshanmen Technology. The transformers were delivered on time, and during the installation and commissioning process, Jinshanmen Technology provided remote technical support. Today, these transformers are operating stably in the Australian project, providing reliable support for the local power engineering works, and leaving Tom highly satisfied with both the product and service provided by Jinshanmen Technology.

 

1. Q: What input and output voltages do you offer?
   A: Our standard configuration provides 120V or 240V input and matching 120V/240V output. Crucially, both input and output voltages are fully customizable to meet your specific project requirements (e.g., 480V input, 208Y/120V output).

2. Q: Why choose oil-immersed over dry-type?
   A: Oil immersion provides superior cooling and insulation, leading to higher overload tolerance, longer lifespan (often 25+ years), quieter operation, and better performance in harsh environments or demanding continuous-duty applications. Oil also protects internal components from moisture and contaminants.

3. Q: What type of oil is used, and does it need replacing?
   A: We use high-grade mineral insulating oil. Unlike engine oil, transformer oil rarely needs full replacement if maintained properly. Key is regular oil testing (DGA, moisture, acidity) and targeted reconditioning (filtration, dehydration) when parameters drift. Our sealed tank designs minimize degradation.

4. Q: Where can these transformers be installed?
   A: They are versatile. Common installations include:

   Outdoor: Pad-mounted (NEMA 3R/4X enclosures), farms, remote sites.

   Indoor: Dedicated electrical rooms (NEMA 1), commercial/industrial buildings (ensure adequate ventilation and containment per codes).

   Critical Applications: Hospitals, data centers (backup power feeds), manufacturing equipment.

5. Q: How do I get a quote for a custom unit?
   A: Provide us with your exact specifications: Required kVA rating, Input Voltage(s), Output Voltage(s), Enclosure Type (NEMA rating), Special Options (taps, protection, BIL, impedance), and Mounting (pad, pole, etc.). Our engineering team will review and provide a competitive quote promptly. Contact our sales team via [Phone/Email].
