Description
Product Overview Of Three Phase Transformer Isolation Type
Furthermore, our Three Phase Isolation Transformer is a low-frequency silicon steel power transformer specially designed for three-phase industrial mains power distribution systems. It adopts high-permeability oriented silicon steel laminated core and full pure copper winding, providing reliable galvanic isolation between primary and secondary circuits to suppress surge voltage, filter common-mode noise and protect backend industrial equipment.
In addition, this three-phase isolation transformer balances three-phase current stably to avoid phase imbalance damage to precision machines. If you need single-phase isolation power conversion solutions for small cabinet equipment, you can check our chassis mount transformer series for reference matching schemes.
Core Performance Advantages Of Three Phase Transformer Isolation Type
Moreover, our three-phase isolation transformer carries exclusive strengths for factory power supply renovation:
- High-density oriented silicon steel core, low no-load loss, low heating during long-time continuous operation;
- 100% pure copper enameled winding, low DC resistance, high power transmission efficiency;
- Full isolation insulation structure, withstand voltage up to 4000Vrms, strong anti-surge capacity;
- Balanced three-phase magnetic circuit design, stable output voltage under unbalanced load;
- Integrated chassis mounting bracket, convenient for cabinet fixed installation;
- Class B / Class F dual temperature resistance winding options, suitable for high-temperature workshop environment;
- Low magnetic leakage shielding structure, effectively reducing electromagnetic interference to adjacent control boards.
