94 Anti-Harmonic Distribution Transformer
This transformer is designed to address the harmonics generated by nonlinear loads such as variable voltage frequency converters (VVVF), inverters, and pulse width modulation (PWM) devices widely used in renewable energy systems.
It features excellent insulation design and superior withstand capability against abnormal surges in the system. It provides renewable energy system customers with a high-efficiency and high-quality transformer option.
95 Environmentally Friendly Energy-Saving Amorphous Steel Vegetable Oil Transformer
Features:
1. Reduced Electricity Costs: The amorphous core vegetable oil transformer reduces load loss by 20%~30% compared to traditional silicon steel transformers, significantly saving on electricity costs.
2. High Fire Safety: Vegetable oil has a high flash point of 360 degrees Celsius, compared to mineral oil's 165 degrees Celsius, providing superior fire resistance and insulation, thus greatly increasing product safety.
3. Environmentally Friendly: The insulating oil is made from edible-grade vegetable oil, which is non-toxic, pollution-free, and completely biodegradable.
4. Low Noise and Long Lifespan: The amorphous core uses unique clamps for fixation, minimizing operating noise. The vegetable oil extends the lifespan of the insulating paper, thus increasing the transformer's lifespan.
96 Amorphous Steel Gas-Insulated Transformer
Features:
1. Energy Saving: Utilizes patented amorphous steel three-legged core manufacturing technology, reducing iron loss to approximately 20%~30% of traditional silicon steel sheets.
2. Safety: SF6 is a non-flammable gas with fire and explosion-proof properties. Equipped with alarm contacts for protective gas pressure gauges, density switches, and thermometers, providing comprehensive protection.
3. Low Noise: The core is housed within a sealed SF6 gas enclosure, resulting in lower noise levels than typical dry-type transformers.
4. Excellent Insulation: The high-voltage conductor sheath and low-voltage interlayer insulation use Class E (120°C) heat-resistant PET material, offering excellent insulation properties in SF6 gas.

Capacity: 3kVA~10MVA
Silicon Steel Sheet Core Features: The surface is specially coated with heat-resistant resin to prevent moisture and corrosion.
After the core is stacked, it is bound with fiberglass straps, increasing the overall core strength and resulting in low loss, low no-load (excitation) current, and low noise characteristics.
The core is fixed with high-strength clamps and screws, providing excellent vibration resistance and mechanical strength.
High Voltage Coil Features: The coil adopts a cylindrical design and is vacuum-infused and heat-cured with epoxy resin. The coil is reinforced with resin and fiberglass, providing high strength against short-circuit mechanical forces and excellent resistance to cracking. It also offers better dust and moisture resistance than traditional H-class dry-type transformers (heat resistance grades F and H are available). When larger capacity transformers require more heat dissipation area, the coils feature single or multiple air channels. This minimizes the temperature difference between the inside and outside of the coil, eliminating thermal stress. Besides being less prone to cracking, this also provides short-term overload capacity. Compared to coils of the same capacity without air channels, they are smaller and lighter.
Low-voltage coil characteristics: For low-voltage and high-current applications, foil conductors are used. A new type of pre-impregnated resin insulation material (PREPREG) is used between the layers. After the coil is heated and hardened, the resin and foil are tightly bonded to form a robust steel body. The upper and lower ends are further sealed with resin, providing strong resistance to instantaneous short-circuit mechanical forces and preventing moisture intrusion. Therefore, power can be restored at any time after a power outage has occurred. (Heat resistance grades F and H are available.)
