Features and Benefits

Isolation transformers prevent transmission of the DC component in signals from one circuit to the other, but allow AC components in signals to pass. Such an isolation ransformer provides a ratio of 1 to 1 between the primary and secondary windings, is widely used to protect secondary circuits and individuals from electrical shocks between energized conductors and earth ground. Additionally, the 1 to 1 isolation transformer has the function of anti-harmonic interference caused by ground loops and comes with electrostatic shields so that such transformers are used for power supplies for sensitive equipment, such as computers, medical equipment, audio equipment, robot devices or laboratory instruments.

Silicon Steel Sheet: New cold rolled silicon steel sheet, 0.27mm, 0.30mm, 0.35mm of thickness, excellent performance.
Terminal Block: High quality terminal block, excellent temperature resistance, pressure resistance and flame retardancy for small power. For high power, made of quality copper material, with good electrical conductivity, high temperature resistance, not easy to burn out the equipment when short circuit happens.
Enameled Wires: H class enamelled copper/aluminum wires, temperature resistance 200℃, winded tightly and uniformly, no insulating layer, high heat dissipation, service life ≥35 years.
Bobbin: The bobbin of isolation transformer is made of nylon, high temperature resistance, great flame retardancy. The high power transformer with frameless design has ventilation slots between the coils for smooth air flows which reduce temperature of coils.
Insulation Process: The 30 kVA isolation transformer adopts H-class vacuum impregnated insulation, temperature resistance of 200°C, lower noise, better insulation and is anti-rust and anti-corrosion.
