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 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: 1,000M 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 protection measures should be taken to ensure the product's lifespan and safety reliability.
Product structural characteristics:
Core: The core is made of high-quality cold-rolled oriented silicon steel sheets with a 45°C full diagonal 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 form, while high-voltage windings have a segmented continuous structure; both are wound with F-grade insulation polyester glass fiber copper wire, reinforced with glass fibers, and the epoxy resin composition is cast and cured under vacuum conditions. They offer excellent electrical properties and mechanical strength. They are capable of withstanding short circuits, impacts, humidity, and have certain overvoltage resistance.
Base: Equipped with bottom foot channel steel or trolley as per customer's request.
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 terminal and secured to the bracket with insulating pillars for easy wiring.
Protective Housing: No housing for IP00, suitable for box-type power stations, switchboards, etc.: IP20i with a metal mesh protective housing, prevents foreign objects up to 12mm from entering, suitable for indoor installation; IP23i with a louvered protective housing, protects against rain, snow, insects, and can be used outdoors, but the usage capacity should be reduced by 5% when using this type of housing.
Cooling: The transformer is typically air naturally cooled (AN), allowing for a continuous output of 100% of its rated capacity. A fan-cooled system can be configured according to customer requirements; with forced air cooling (AF), the transformer's output capacity can be increased by up to 30%.
Temperature Control: Equipped with an automatic temperature control protection system; features include temperature display, circulating detection, fan start/stop, over-temperature alarm, circuit breaker, and computer communication interface, all customizable to user requirements.
