Power System 100kVA, 10kV/0.4kV, 50Hz/60Hz
Certifications IEC 62271-200, IEC 694, GB3906, DIN VDE 0670
This 100kVA 3 phase distribution transformer was formally put into production at Huajidian factory in 2015. It is a standard step-down transformer with rated power of 100 kVA, primary voltage 11kV and secondary voltage 0.38kV. The primary side is fitted with a ±2×2.5% no-load tap changer, which can flexibly adjust voltage to adapt to complex power supply conditions.
We adopt advanced production technology and high-quality raw materials and components in manufacturing. All finished products pass comprehensive acceptance tests before delivery. For more than a decade, our transformers have maintained a zero failure rate in actual operation. The overall design fully meets mainstream international standards including IEC and ANSI, with excellent overall performance far exceeding traditional old models.
The 100kVA 3 phase distribution transformer is reasonably priced and features low energy consumption. It is the ideal choice for small and medium-sized projects with limited budgets, balancing performance and cost perfectly.
The corrugated fuel tank with full sealing structure can isolate external air and moisture effectively. There is no need for frequent oil replacement, greatly reducing daily maintenance workload.
Equipped with anti-corrosion oil tank and ceramic sleeve, the product resists wind, sunlight, rain and other harsh outdoor conditions, running stably all year round.
It generates little noise during operation. Even installed near residential areas and villages, it will not cause disturbance to the surrounding living environment.
Original factory production with mature craftsmanship and strict multi-channel quality inspection. We provide full-cycle after-sales service to eliminate customers’ worries about use.
A rural power grid renovation project in northern China adopted 20 sets of our 100kVA 3 phase distribution transformers in 2022. These transformers were installed on poles in scattered villages, undertaking the power distribution work for residents’ daily electricity and small household equipment.
After three years of field operation, the equipment has endured high temperature in summer, frost in winter and rainy and humid weather all year round. No oil leakage, voltage instability or component damage occurred. Its low noise also won unanimous recognition from local villagers. The project party stated that this model is stable, durable and almost maintenance-free, which greatly reduces the later operation cost of the power grid.
Q1: Is this 100kVA 3 phase distribution transformer suitable for long-term outdoor pole-mounted installation?
A1: Yes. The product has built-in anti-corrosion and weather-resistant coating, matched with anti-corrosion oil tank and ceramic sleeve, and can be directly installed on poles or the ground. For coastal areas with severe salt spray, we can also customize enhanced anti-corrosion coating to further extend service life.
Q2: Can we customize parameters such as voltage and accessories for this transformer?
A2: Customization is supported. We can adjust voltage levels, wiring modes, and configure temperature control and other accessories according to actual site demands, covering both standard specifications and special customized requirements.
Q3: What is the difference between this fully sealed transformer and the model with an oil storage tank?
A3: Each type has unique advantages. The fully sealed type is maintenance-free, moisture-proof and dust-proof, more suitable for outdoor and harsh environments; the transformer with an oil storage tank has better heat dissipation performance and fits scenes with long-term high load operation. We will recommend the most appropriate model based on your on-site environment and load conditions.
