Clamps
◆ The clamp adopts channel steel pre-bend technology, which has high strength and large clamping force.
◆ Channel steel surface is treated by sandblasting treatment, electrostatic spraying, suiting for almost environment. -
Iron Core
◆ Made of high quality cold-rolled grain-oriented electrical steel sheet.
◆ 45° full diagonal joint, multi-step overlap.
◆ Iron yoke no punching, drawing plate structure, no overlay iron yoke technology.
◆ The surface of the core sheet is coated with resin paint, and the surface of the clamp is sprayed with electrostatic spray, moisture-proof, rust-proof and salt spray proof.
◆ Low no-load loss, no-load current and noise. -
Low Voltage Coils
◆ Copper foil or aluminum foil winding, according to the transformer low voltage current size double layer and winding or series winding.
◆ Automatic argon protection welding is adopted between copper foil and copper bar, which is reliable and has low resistance.
◆ German HEDRICH equipment epoxy resin vacuum casting, coil electrical and mechanical strength is high, strong resistance to sudden short circuit.
◆ Quartz powder is added to the epoxy resin, and the inner and outer surfaces of the coil are reinforced by glass fiber mesh cloth, which has good heat dissipation, moisture resistance and flame retardant performance.
◆ Heat dissipation requires a single or multi-layer ventilation duct to effectively reduce the temperature rise of the low-voltage coil. -
Cooling Fan
◆ The low noise cross-flow fan can reduce the winding temperature, improve the over-load capacity and extend the transformer life after starting.
◆ When forced air cooling is used, the rated capacity of the transformer can be increased by 40%-50%.
◆ Stainless steel shell fan, large air volume, low noise, high reliability, low power consumption and easy installation. -
High Voltage Coils
◆ Copper foil or aluminum foil winding, interlayer low voltage, large capacitance, strong transformer lightning impact resistance.
◆ German HEDRICH equipment epoxy resin vacuum casting, high coil electrical and mechanical strength, small local discharge.
◆ The high voltage coil can be set according to the heat dissipation requirements of the ventilation duct (the company's patented technology ZL201921375730.4).
◆ Quartz powder is added to the epoxy resin, and the inner and outer surfaces of the coil are reinforced by glass fiber mesh cloth, which has good heat dissipation, moisture resistance and flame retardant performance.
◆ The coil is welded with automatic argon protection, which is reliable and has low resistance.
