Improved construction, compact size, superior reliability
C-class Dupont Nomex paper
highly insulating
With electromagnetic and structural optimization design, small size and lower noise
Core is made of superior steel, outstanding performance of magnetic conduction. Joint is processed by 45° oblique angled technique, with low loss & low noise.
Blowers with metal cover, fan’s interface with metal cover
Winding structure is pie type, which can manage with the field strength effectively. Plus the NOMEX paper used, which ensures very low partial discharge.
Coil is made of oxygen-free copper, low resistance and low loss, but high efficiency.
Insulation material: NOMEX paper of DUPONT brand, insulation Class C, heat-resistant is up to 220℃, with excellent overload capacity.
