- 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 180℃, winded tightly and uniformly, no insulating layer, high heat dissipation, service life 20 years.
- Bobbin: 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 180°C, lower noise, better insulation and is anti-rust and anti-corrosion.
KNOWLEDGE BASE --- What is Isolation Transformer?
- Isolation transformer is a transformer with electrical isolation between the input winding and the output winding and is a transformer used to electrically isolate two or more circuits with a coupling relationship.
- Single phase isolation transformers are dry type isolation transformers generally used for machine repair and maintenance to protect against lightning and filter to avoid accidental hit at the same time. The transformer isolates the respective currents of the primary and secondary windings.
- Isolation transformers are widely used in general circuit control power supplies, safety lighting and indicator lights in the electronics industry or industrial and mining, machine tools and mechanical equipment.
