Product Description
Product Description
The three-phase isolation transformer is the main component of various power supplies and electrical equipment. It is 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 from
the equipment, and the primary and secondary plus copper foil shielding, effectively protecting the power grid harmonics from interfering with
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
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 secondary air duct fan is fast, galvanized tripod, vacuum dipping paint, 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.
