Varelen technology: What makes our factory are different?

Varelen electric used most advanced production technology and the most control systems to guarantee the transformer products quality and total product reliabliity.

1. 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.

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

3. HV and LV 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.

4. Varelen practices strictly exclusive casting system of F(155℃) or H(180℃), and the epoxy resin is injected and casted in the vacuum machine, so it’s highly insulated, dust-proof and moisture-proof, which ensures stable and reliable performance.
