Dry Type Transformer

Product Description

We produce various low voltage dry type iron core transformers: 1. Isolation transformer Used for safety isolation, lower leakage current, power conditioner for eliminating 3rd harmonic wave and common mode interference suppression. 2. Coupling transformer Applied for Active compensation of harmonic currents as output coupling to network. 3. Frequency variable and voltage variable VFVV inverter output transformer (*0~**0Hz)(0~**0V). Used as output transformer for UPS, EPS. It has leakage inductance(1~5mH) as filter choke for *0~*0KHz, and isolation output for *0~**0Hz. 4. Buck & Boost transformer (two coils type) Used for power voltage increase or decrease, and has isolation. 5. Auto-transformer (one coil tap) Used for power voltage increase or decrease. It is more energy saving than(4) but has no isolation. 6. Voltage regulator (one coil with contactor) With patented wire drive and roller brush, it has long life and wide range voltage variable easy to control and maintenance, high efficiency with no wave and phase distortion. Combined with controller it can be integrated in Automatic Voltage Regulator(AVR). 7. Special transformer 7.1 Constant Voltage Transformer(CVT) See detailed description later 7.2 Vector transformer Applying the phase vector of the transformer, it is three phase with one phase line voltage output or one phase Y-voltage output. 7.3 Inductance variable transformer It is need for continuously reactive power compensation. 7.4 Shifter transformer The phase angle of output three phase can variable shift from . The specifications of the transformers as and output, capacity, voltage, current, frequency(*0~**0Hz), temperature rise, insulation class and noise and so on can be custom designed. Features: There are air flows between coil�s layer to layer and between coil to core, thus heat escapes quickly, and temperature rises lower. There are no flammable insulating material on the coil surface and between coil layer and layer to avoid the fire hidden danger. Small volume, light weight and good workmanship. After vacuum pressure impregnating, the whole transformer is moisture proof and mildew proof. Insulation class F or H. Lower audio-noise.We produce various low voltage dry type iron core transformers: 1.
