Our product advantages

Magnetic Core

The three-limb iron core is made of oblique cut Grain-oriented, seven-step silicon steel laminations insulated on both sides, guaranteeing low losses and low noise. These values are even improved by laser treatment. It is protected on the surface with a flash-proof varnish in order to prevent the sheet from corrosion and to reduce the noise.
Clamping frame

Clamping frame processed by CNC cutting, bending and then one-time punch forming, the hole’s size is accurate and the appearance looks delicate.
winding

The winding coil is made of oxygen-free copper, class H for main insulation materials and coil is insulated by NOMEX paper of DUPONT brand, LV winding is isolated by copper foils. All these make the heat-resistant is up to 220℃, with excellent overload capacity and low loss, but high efficiency.
High voltage coil

The winding coil is made of oxygen-free copper, class H for main insulation materials and coil is insulated by NOMEX paper of DUPONT brand, with excellent overload capacity and low loss.
Low voltage coil

The low voltage winding designed as foils winding, Reduction of extra losses, Balanced temperature distribution within the winding, High short-circuit capability.
