Application: This product boasts excellent insulation properties, high mechanical strength, resistance to moisture, flame retardancy, and non-toxicity. It is easy to install, requires minimal maintenance, has a long service life, and strong edge loading capacity. It is widely used in important locations such as hospitals, hotels, underground shopping malls, tunnels, subways, underground power stations, offshore oil platforms, laboratories, high-rise buildings, airports, and combined power stations.
Product Usage Conditions:
Altitude: 1000M and below.
Ambient Temperature: Maximum Temperature: +40°C
Highest Average Daily Temperature: +30°C | Highest Average Annual Temperature: +20°C
Lowest Temperature: -30°C (for outdoor transformers) / -5°C (for indoor transformers)
Relative Humidity: 95% and below
When the operating conditions exceed the aforementioned requirements, appropriate adjustments should be made to the operating parameters (such as output current) and suitable protective measures should be implemented to ensure the product's lifespan and safety reliability.
Product Structure Features:
Core: The core is made of high-quality cold-rolled oriented silicon steel sheets, featuring a 45°C full oblique joint non-punching structure; the core surface is coated with a special resin to prevent rust; elastic materials are used between the clamping device and the core, the coil and the core, and the core and the base to reduce operating noise.
Coils: Low-voltage windings are in double-layer cylindrical or foil style, while high-voltage windings feature a segmented continuous structure; both are wound with F-grade insulation polyester glass fiber copper wire, reinforced with glass fiber, and cast into shape using epoxy resin under vacuum. They offer excellent electrical properties and mechanical strength. They can withstand short circuits, shocks, moisture, and have certain overvoltage resistance capabilities.
Base: Fitted with either slot steel or a trolley according to customer requirements.
Termination Connectors: High-voltage wiring terminals are connected using pre-inserted copper nuts; low-voltage wiring uses nickel-plated (or tin-plated) copper bars with wiring holes, which are welded to the coil terminals. They are then fixed to the bracket with pillar insulators for easy wiring.
Protective Enclosure: IP00 does not include a protective enclosure; suitable for box-type power stations, distribution cabinets, etc.: IP20i comes with a metal mesh protective enclosure, which can prevent foreign objects up to 12mm in size from entering; suitable for indoor installation; IP23i features a louvered protective enclosure, which can protect against rain, snow, insects, and is suitable for outdoor use; however, reduce the usage capacity by 5% when using this type of enclosure.
Cooling: The transformer is typically cooled by air natural (AN), allowing for continuous output of 100% rated capacity. According to customer requirements, a forced air cooling (AF) system can be configured; with AF, the transformer's output capacity can be increased by up to 30%.
Temperature Control: Equipped with an automatic temperature control protection system; features such as temperature display, circulating detection, fan start/stop, over-temperature alarm, circuit breaker, and computer communication interface can be achieved according to customer requirements.
