When choosing 10kV transformers, one often encounters problems - traditional Oil Immersed Transformers are prone to oil leakage, polluting the environment and causing fires; they are large in size and occupy a lot of space, making installation difficult when the workshop or photovoltaic station space is tight; if they are to be installed in a Photovoltaic Prefabricated Cabin, ordinary Dry Type Transformers have poor heat dissipation and low adaptability, and operate unstably. Hualai Electric's 10kV SC14 Dry-Type Transformer 125kVA specifically addresses these issues. It is oil-free, safe, compact in size, and can be adapted to photovoltaic prefabricated cabins. Whether for industrial power supply or Photovoltaic Energy Storage, it can operate reliably.
Product Description
The Hualai Electric 10kV SC14 dry-type transformer is an energy-efficient Dry Type Transformer. It is manufactured using an epoxy resin casting process. The core is made of high-magnetic-conductivity silicon steel sheets, and the windings are copper wires, ensuring good conductivity and low loss. Unlike Oil Immersed Transformers, it has no oil tank and thus does not pose a risk of oil leakage. The casing is made of anti-corrosion steel plate and is coated with insulating paint, making it suitable for outdoor or enclosed space installation. The equipment is 40% smaller in volume and 30% lighter than the same capacity Oil Immersed Transformer, allowing it to be easily installed in Photovoltaic Prefabricated Cabin without the need for additional expansion of the cabin. It is equipped with an automatic forced air cooling system, which automatically starts to dissipate heat when the temperature is high, ensuring long-term full-load operation. The wiring terminals are well-arranged, facilitating the connection with photovoltaic inverters and the power grid, without the need for complex modifications. Technical Specifications
This transformer has a rated capacity of 125kVA, with a high-voltage side voltage of 10kV and a low-voltage side voltage of 0.4kV. It meets the requirements for industrial low-voltage power distribution and photovoltaic grid connection. The impedance voltage is 4%, which complies with the national grid connection standards and will not cause an impact on the grid during grid connection. The no-load loss is ≤200W, the load loss is ≤1200W, and it is 15% more energy-efficient than the ordinary SCB13 series Dry Type Transformer, saving hundreds of kilowatt-hours of electricity annually. The insulation grade is F class, with a maximum allowable operating temperature of 155℃. The operating temperature range is -30℃ to 40℃, and the performance is stable under high-temperature exposure or low-temperature conditions. The temperature rise limit is ≤80K (under rated load), and the temperature rise can be reduced by 15K when using forced air cooling, further enhancing the overload capacity. The protection level is IP20, which can prevent foreign objects from entering and is suitable for the enclosed environment of the Photovoltaic Prefabricated Cabin.
Product Features and Advantages
The Hualai Electric 10kV SC14 transformer precisely meets the user's needs. Firstly, it is oil-free and safe. The epoxy resin casting structure replaces the oil tank, eliminating the risks of oil leakage and fire. It is more suitable for densely populated or enclosed spaces than Oil Immersed Transformer. Secondly, it is compact and space-saving. It has a small volume and light weight, which can be installed in the Photovoltaic Prefabricated Cabin, saving the cost of site occupation. Thirdly, it is energy-saving and low-consumption. The low no-load and low-load losses reduce electricity expenses over the long term. Fourthly, it has reliable heat dissipation. The forced air cooling system ensures stable operation at high temperatures, has strong overload capacity, and does not worry about load fluctuations. Fifthly, it has wide adaptability. It can be used for industrial plant power distribution and is also suitable for photovoltaic grid connection scenarios, without the need to purchase separately for different purposes.
Application scenario
The industrial park uses it as a distribution transformer. Its oil-free design avoids polluting the workshop floor, and its compact size does not occupy excessive production space. The photovoltaic power station installs it in the Photovoltaic Prefabricated Cabin and uses it in conjunction with the photovoltaic inverter to achieve the step-up and grid connection of photovoltaic power. The commercial complex uses it for low-voltage distribution, achieving low energy loss and reducing the overall electricity cost of the shopping mall. The data center uses it to power the server room, with its oil-free safety features suitable for the fire prevention requirements of the data center, ensuring stable operation and uninterrupted data transmission. The off-grid photovoltaic system in remote areas uses it to convert photovoltaic power into low-voltage electricity, meeting the electricity needs of local residents and small businesses.
Customer Benefits
Choosing this transformer enables enterprises to significantly reduce operating costs and risks. The oil-free design reduces oil leakage cleaning and equipment maintenance costs, avoiding environmental penalties caused by oil leakage; the compact size saves the cost of station construction or cabin expansion, especially suitable for photovoltaic projects with limited space; energy saving and low consumption reduce electricity expenses over the long term, and can recover the equipment price difference in the short term. Stable operation reduces the number of power outages and avoids production losses or data loss due to power outages; its wide adaptability eliminates the need to stockpile multiple transformers, reducing inventory pressure. For photovoltaic projects, it can be quickly installed in the Photovoltaic Prefabricated Cabin, shortening the construction period and achieving early grid connection benefits.
Customer Reviews and Recommendations
Engineer Li from the photovoltaic power station said: "Previously, we used Oil Immersed Transformer and had to expand the cabin to install the Photovoltaic Prefabricated Cabin. After replacing it with this SC14 dry-type transformer, we could directly install it, and the forced air cooling has good performance, operating stably even at full load in summer. It is much more energy-efficient than ordinary Dry Type Transformer." Manager Wang from the industrial park commented: "The previous transformer always worried about oil leakage. After replacing it with this oil-free one, we were completely at ease. The small size allows it to be placed in a corner without occupying space, and the no-load loss is low. Our monthly electricity cost has saved over 200 yuan compared to before, and it has not had any faults in one year of operation." Engineer Zhang from the power engineering recommended: "When doing photovoltaic and industrial projects, this transformer is often chosen. Its oil-free safety, wide adaptability, and compatibility with Photovoltaic Prefabricated Cabin are suitable for the fire prevention requirements of the data center. Customer feedback shows significant energy-saving effects, And there were very few problems regarding the after-sales service.It has a much higher price-performance ratio than Oil Immersed Transformer at the same price range."
