Features
The small isolation transformer is a 3 phase isolation transformer. Peaco Support provides custom isolation transformer with special input and output voltages. For example, 240V to 240V isolation transformer, 440V to 230V step down transformer, 380V to 460V step up transformer, 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, 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 dry type 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 whole dry type isolation transformer adopts H-class vacuum impregnated insulation, temperature resistance of 200°C, lower noise, better insulation and is anti-rust and anti-corrosion.

KNOWLEDGE BASE --- What is Isolation Transformer?
Isolation transformer is such a transformer in which the input winding and output winding are electrically isolated 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 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.
