Application: This product boasts excellent insulation properties, high mechanical strength, resistance to moisture, flame retardancy, and is non-toxic. It is easy to install, requires minimal maintenance, has a long service life, and strong edge loading capabilities. 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) | Lowest Temperature: -5°C (for indoor transformers)
Relative Humidity: 95% and below
When conditions exceed the aforementioned requirements, appropriate adjustments should be made to operating parameters (such as output current) and proper protective measures should be taken to ensure the product's service life and safety reliability.
Product Structure Characteristics:
Core: The core is made of high-quality cold-rolled oriented silicon steel sheets with a 45°C full oblique joint without punching structure; the core surface is coated with a special resin to prevent rust; elastic materials are used between the clamping pieces and the core, the coils and the core, and the core and the base to reduce operating noise.
Coils: The low-voltage windings are in a double-layer cylindrical or foil configuration, while the high-voltage windings have a segmented continuous structure; both are wound with F-grade insulation polyester yarn copper conductors, reinforced with glass fiber, and the epoxy resin mixture is cast into shape under vacuum. They offer excellent electrical properties and mechanical strength. They can withstand short circuits, shocks, moisture, and have certain overvoltage resistance capabilities.
Base: Foot slot steel or trolley provided according to customer's requirements.
Terminal Connectors: High-voltage wire connections use pre-buried copper nuts for connection; low-voltage wiring employs nickel-plated (or tin-plated) copper bars with wiring holes, which are welded to the coil terminals and secured to the bracket with insulating pillars 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, but the usage capacity should be reduced 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. Upon customer requirement, a forced air cooling (AF) system can be configured; with AF cooling, the transformer's output capacity can be increased by up to 30%.
Temperature Control: Equipped with an automatic temperature control protection system; functions such as temperature display, circulation detection, fan start/stop, over-temperature alarm, circuit breakage, and computer communication interface can be achieved according to user requirements.
