Track transformers E'lektrotexniceskii zavod POBS, PTM-A, PRT-A, PT, etc.

Self-locking transformers of the POBS, PTM-A, PRT-A, PT types are used on railways to power auto-locking and alarm circuits in alternating current electric networks with a frequency of 25 and 50 Hz
The structure of the symbol
POBS-HA:
P - track; O - single-phase; B - armored; C - dry;
X is the ordinal number of the type (2; 3; 5);A is a modification of the transformer.
PRT-A: PRT - track relay transformer; A - modification of the transformer.
PT-25A: PT - path transformer; 25 - current frequency, Hz; A – modification of the transformer.
PTM-A: PTM is a small-sized track transformer; A is a modification of the transformer.

Models: PTM-A, PT-25A, PRT-A, POBS-2A, POBS-ZA, POBS-5A, PTM-AP, PT-25AP, PRT-AP, POBS-2AP, POBS-3AP, POBS-5AP, PTM-AG, PT-25AG, PRT-AG, POBS-2AG, POBS-ZAG, POBS-5AG

Track and signal transformers with improved sealing have the abbreviation GW in their name. Electrical parameters, as well as overall and connecting dimensions correspond to transformers of general industrial design, at the same time, the moisture protection of the transformer has been significantly improved.
In GV series transformers, the base and top cover are made of glass-filled armamide, and the inside of the assembled transformer is completely filled with a special electrical compound, which ensures the tightness of the coil and the terminals of the contact group.

Models: PTM-AGV, PT-25AGV, PRT-AGV, POBS-2AGV, POBS-3AGV, POBS-5AGV

About E'lektrotexniceskii zavod

Electrotechnical Plant (Kaluga) produces industrial transformers with a capacity from 0.02 kVA to 100.0 kVA

  • VACUUM IMPREGNATION

    It affects the service life of transformers. For impregnation, an electrical insulating varnish is used, then drying at 105 degrees Celsius.

  • WELDING OF THE MAGNETIC CIRCUIT

    Argon welding was mastered in 1990. It reduces the manufacturing time of transformers and requires high-quality manufacturing of the magnetic circuit.

  • WINDING EQUIPMENT

    Provides high-quality ordinary winding of a round wire without the formation of short-circuited turns. The rectangular wire is wound on machines of its own production.
