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.
