Product Description

Three-phase isolation transformers are the main components of various power supplies and electrical equipment, and are manufactured using high-quality materials and advanced technology. The transformer completely insulates the electrical between the primary and secondary sides and isolates the circuit. That way, a short circuit on the primary side does not affect the secondary side. The three-phase isolation transformer not only has the function of voltage transformation in the power grid, but also isolates the third harmonic of the power grid to the equipment, and the primary and secondary plus copper foil shielding, effectively protecting the interference of the power grid harmonics on the equipment. It is especially suitable for import and export equipment between 0.1KVA-1600KVA, suitable for various three-phase power supply occasions with AC 50 ~ 60HZ, input and output voltage not exceeding 1600V. Product input and output voltage (three-phase or multi-channel input and output, etc.), connection method, adjusting tap position, winding capacity allocation, secondary winding equipment, outer box (selected according to different use environments), can be based on user Requires careful design and manufacturing. 

Our Advantages

High quality new cold-rolled oriented silicon steel sheets are used for stacking; H-class temperature-resistant 180 ° enameled wire, bare coil winding is beautiful and elegant, primary and secondary air duct fans are hot, galvanized feet, vacuum dipping paint, and oven drying! Effectively reduce vibration and noise during operation, increase electrical strength, and introduce new processes and technologies such as the design of high-temperature-resistant insulating materials, making the product more energy-efficient and quieter. The energy-saving and low-noise coil has a ventilation slot, and the air flow is smooth, and the coil temperature is quickly and effectively reduced.
