Isolation transformers are designed to transfer energy between circuits with complete galvanic isolation, ensuring protection against electric shocks, noise reduction, and enhanced safety in industrial, commercial, and hospital installations.
Technical Features
- The nominal power range of isolation transformers varies from 5 kVA to 1000 kVA and can be adjusted according to the specific needs of each project.
- Typical operating voltages: 220 V to 380 V + N, 440 V to 220 V + N, 380 V to 440 V + N, 220 V / 380 V, and 440 V + N – Others upon request.
- Connection configurations can be carried out in Star (Y), Delta (Δ), or Star with accessible neutral, providing flexibility according to the electrical system.
- Operating frequency: 50 Hz or 60 Hz, meeting both national and international standards.
- Electrical insulation is designed in thermal Class F or H, ensuring resistance to temperature rise and extended service life of the equipment.
- Protection degree options: IP-21, IP-23, or up to IP-55, depending on the environmental conditions at the installation site.
- Cooling system: AN (Air Natural), ensuring efficiency and reliability in heat dissipation.
- Built with grain-oriented silicon steel core and copper or aluminum windings, vacuum-impregnated with insulating varnish, providing robustness, stable performance, and high durability.
- Provides electrical isolation between primary and secondary windings, ensuring greater safety, surge protection, and reduction of electrical noise.
