Torodial Transformer

ESPEE is a pioneer in the manufacture of Toroidal Power Transformers in India. Its thrust is towards customized Toroidal Transformers for the domestic and international markets. Espee Toroidal Transformers have a Va rating between 50 to 3 KVA. Their tape wound CRGO silicon steel core are constructed with metal tape wound onto a mandrel under closely controlled tension, then annealed and treated to fully develop the required magnetic characteristics of Torodial cores are never dependent on their assembly. The air gap in this core is zero. The super enameled copper wire is then wound by an automatic winding machine uniformly around the entire length of the toroid, assuring uniform quality.

The shape of the core is such that the magnetic field of the toroid is contained within itself. Hence there’s no radiation of stray magnetic flux and the Transformer can be placed in high density electronic circuitry without any interfering hum. Leakage inductance and stray capacitance are also very small. And when the Toroidal Transformer is placed in an interfering field, the interfering forces tend to act equally all around the toroid, resulting in the cancellation of interfering voltages in the coils in a manner similar to the astatic windings.
