100 kVA 3-Phase Autotransformer, 380V to 220/200V

Three phase 380 volt to 220/200 volt step down autotransformer, 100 kVA power rating, primary and secondary windings are separated by aluminium/copper shield, input and output voltage supports customization service, long use life span and high efficiency.

Applications: The 3-phase autotransformer can be used in CNC production equipment, SMT, printing machines, electrical discharge machines, automatic plug-in machines, precision measuring equipment, laser cutting machines, plastic molding machines, medical monitoring systems, PCB drilling machines, laboratory equipment, military use Instrumentation control center, etc.

Specification

Features

• 3-phase autotransformer has enough power, the wiring is tight and neat, and does not skip turns. Coils adopt insulated H-class enameled wire, with low no-load current and low loss.
• The 100 kVA dry-type autotransformer has built-in silicon steel sheet, which has good magnetic flux performance, high heat dissipation coefficient and low magnetic loss.
• The autotransformer uses electrophoresis technology clamps, no burrs on the edges, rounded corners to prevent collisions, and not easy to corrode.
• Tinned copper tube terminals and rail-type wiring ports are convenient for wiring and ensure that the power-on overload capacity is increased to the extreme.

Tips: 100 kVA 3-phase autotransformer functions.

• 100 kVA 3-phase autotransformer is used in applications where primary and secondary isolation is not required. It has the advantages of small size, less consumables and high efficiency.
• Fundamentally speaking, 100 kVA 3-phase autotransformer is to save a coil and reduce costs, and it has functions of an ordinary transformer, that is, to step up or step down for the circuit voltage, isolate and reduce impedance.
• 100 kVA 3-phase autotransformer can also be made into an AC voltage regulator to flexibly change the output voltage for use in the laboratory.
• Power supply mode of 100 kVA 3-phase autotransformer is very suitable for the power supply of large-capacity loads. It has little interference to communication lines, so it is widely used by passenger dedicated lines and heavy-duty freight railways.
• In the current power grid, there is almost no autotransformation below 220 kV. 3-phase autotransformer has only been used since the 220kV voltage level, and it is mostly used as the connection between the power grids.
