This transformer is placed in a telephone set.

The telephone transformer is used to connect individual elements of the conversational part of the circuit, as well as to coordinate their resistance with the input resistance of the subscriber line. about 110 volts. The low-frequency transformer is a plastic frame with windings, inside which there is a core assembled from transformer steel plates. The leads of the ends of the windings are soldered to the legs pressed into the cheeks (walls) of the plastic frame. The windings are made of copper wire with a diameter of 016 mm. wires PETV-1-016 enameled wire, heat-resistant high-strength enamel of refined thickness (type 1). On the transformer are the numbers 1.2.3.4.6. wires 2-3 are soldered to legs 2-3 between them 32 Om- + 10%. number of turns 645. Legs 5-4 are also soldered wires between them 30 Ohm. + - 10%, number of turns 520. Legs 5-6 are also soldered the resistance between them is 32 Ohms + -10% the number of turns is 770.
