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.
• 1 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: Autotransformer definition.

An autotransformer refers to a transformer with primary and secondary windings on the same winding. The primary and secondary windings are directly connected in series and coupled by themselves. According to structure, autotransformers can be divided into variable type and fixed type. Auto-coupling means electromagnetic coupling. Ordinary transformers transfer energy through the electromagnetic coupling of the primary and secondary coils, and there is no direct electrical connection between the primary and secondary sides. The primary and secondary sides of an autotransformer have a direct electrical connection, and its low-voltage coil is a part of the high-voltage coil. Autotransformers are also used as protection equipment in the protection equipment of communication lines.
