Usage: 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 critical 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 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 lifespan and safety reliability.
Product Structure Features:
Core: The core is made of high-quality cold-rolled oriented silicon steel sheets with a 45°C full oblique seam without punching structure; the core surface is coated with a special resin to prevent rust; elastic materials are used between the clamping parts 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 type, while high-voltage windings are in segmented continuous structure; both are wound with F-grade insulation polyester glass fiber copper wire, 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.
Base: Supplied with either a foot slot steel or a trolley, as per customer's request.
Terminal Connectors: High-voltage wiring terminals are connected using pre-buried copper nuts; 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 spacers for easy wiring.
Protective Housing: No housing for IP00, suitable for box-type power stations, distribution cabinets, etc.: IP20i with metal mesh protective housing, prevents objects up to 12mm from entering, suitable for indoor installation; IP23i with louvre-style protective housing, protects against rain, snow, insects, and can be used outdoors, but reduce the usage capacity by 5% when using this type of housing.
Cooling: The transformer is typically cooled by air natural (AN), at which point, it can continuously output 100% of its 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, circuit checking, fan start/stop, over-temperature alarm, trip, and computer communication interface can be achieved according to user requirements.
