Features
The small isolation transformer is a 3-phase isolation transformer. Peaco Support provides a custom isolation transformer with special input and output voltages. For example, 240V to 240V isolation transformers, 440V to 230V step-down transformers, 380V to 460V step-up transformers, etc can be also customized. The three-phase isolation transformers in Peaco Support have the following features and benefits:
- 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, and high temperature resistance, not easy to burn out the equipment when a short circuit happens.
- Enameled Wires: H class enameled copper/aluminum wires, temperature resistance 200℃, winded tightly and uniformly, no insulating layer, high heat dissipation, service life ≥35 years.
- Bobbin: The bobbin of dry type isolation transformer is made of nylon, high-temperature resistance, and great flame retardancy. The high-power transformer with a frameless design has ventilation slots between the coils for smooth air flows which reduces the temperature of the coils.
- Insulation Process: The whole dry-type isolation transformer adopts H-class vacuum-impregnated insulation, temperature resistance of 200°C, lower noise, better insulation, and anti-rust and anti-corrosion.

Isolation Transformer Schematic Diagram
KNOWLEDGE BASE --- What is an Isolation Transformer?
The isolation transformer is a transformer in which the input winding and output winding are electrically isolated from each other to avoid accidental contact with the charged objects (or metal parts that may be charged due to insulation damage) and the ground at the same time.
The principle of 3 phase isolation transformer is the same as that of an ordinary dry-type isolation transformer and both are based on the principle of electromagnetic induction. It mainly isolates the primary power circuit and the secondary circuit floats to the ground to ensure the safety of electricity use.
