I. Product Overview
Hualai Electric 10 kV SCB13 Dry-Type Transformer 200kVA is an efficient dry-type power equipment developed for medium and low voltage distribution scenarios, and it is an upgraded version of Dry Type Transformer. It uses epoxy resin vacuum casting technology to encapsulate the windings, and the core is made of high-permeability cold-rolled silicon steel sheets. Unlike Oil Immersed Transformer, it does not rely on insulating oil for heat dissipation and can be directly installed in indoor and underground distribution rooms and other humid environments. Its core advantages lie in low loss and strong moisture resistance. It can complement Amorphous Alloy Dry-type Transformer in capacity and meet the 200kVA power distribution needs of commercial and industrial scenarios. It is the mainstream choice to replace traditional high-loss transformers.
II. Technical Specifications
Rated parameters: Voltage 10kV/0.4kV, capacity 200kVA, impedance voltage 4%, in compliance with GB/T 10228-2015 standard; Loss indicators: No-load loss ≤ 320W, load loss ≤ 2400W (at 1.2 times rated current); Material structure: Windings are made of oxygen-free copper wire, core lamination factor ≥ 0.96, shell is cold-rolled steel plate with plastic coating; Environmental adaptability: Insulation class F, maximum temperature rise ≤ 100K, operating temperature -25℃ - 40℃, moisture resistance grade IP20 (95% relative humidity without condensation); Physical dimensions: Length 1250mm × Width 800mm × Height 1300mm, weight approximately 850kg, installation floor area is 30% less than that of Oil Immersed Transformer of the same capacity.
III. Product Features and Advantages
Moisture-proof and durable: The epoxy resin cast windings are completely sealed, solving the problem of moisture absorption and short circuit in ordinary Dry Type Transformer. It has been used in underground distribution rooms for 3 years without failure, and its lifespan is 5-8 years longer than that of traditional dry-type transformers.
Energy-saving: Low-loss core and copper winding design, saving about 1200 kWh per year, with energy consumption close to Amorphous Alloy Dry-type Transformer but at a 20% lower purchase cost.
Safe and easy to install: No insulating oil design eliminates the risk of oil leakage and fire in Oil Immersed Transformer, allowing it to be installed in densely populated areas such as shopping malls and hospitals. No oil pit is required, reducing installation time by 1 day compared to oil-immersed transformers.
IV. Application Scenarios
Commercial buildings: Underground distribution rooms in shopping malls and office buildings, suitable for humid environments, with low noise (≤55dB) that does not affect business operations. The 200kVA capacity can meet the power supply needs of air conditioning and elevators in 10-story office buildings.
Industrial workshops: Distribution in electronic and food factories, no oil pollution to products, F-class insulation can withstand workshop temperatures up to 40℃, ensuring 24-hour power supply for production lines.
Public facilities: Outpatient buildings in hospitals and teaching buildings in schools, safe with no fire hazards, low loss reduces public electricity costs, and can operate stably during the rainy season.
V. Benefits for Customers
After purchase, it can reduce installation space by 30%, saving about 20,000 yuan in oil pit construction costs. Save 1,200 kWh of electricity annually, and save 60,000 yuan in electricity bills over 5 years; the moisture-proof and durable features reduce maintenance frequency, saving approximately 5,000 yuan in maintenance costs each year; no safety risks, avoiding production stoppage losses caused by transformer failures, especially suitable for scenarios with high requirements for safety and energy conservation.
VI. Customer Testimonials and Reviews
"The Dry Type Transformer in the underground power distribution room of our shopping mall used to fail due to moisture frequently. After switching to Hualai Electric's model, there have been no power outages even during the rainy season. The 200kVA capacity is just right for the mall's electricity needs, and we have saved over 1,000 kWh of electricity in a year." - Manager Liu from the property department of a chain shopping mall.
"The food factory cannot have oil stains. This oil-free transformer is perfect. It remains stable even on hot days in the workshop and is safer than Oil Immersed Transformer. We haven't had to maintain it in the past two years." - Engineer Zhang, equipment supervisor of a food factory.
"We installed this transformer in the teaching building of our school. We didn't need to dig an oil pit, saving money. The low noise doesn't affect classes. The power bureau inspection said the energy consumption met the standards, and we were awarded the title of energy-saving demonstration unit." - Director Wang from the logistics department of a middle school.
