Terminal Type Pad-mounted Transformer

The ZGS series from TAILI ELECTRIC is a compact and reliable power distribution solution widely used across North and South America. Designed for outdoor pad-mounted installation, it combines transformer, switching, and protection functions into one integrated unit—ensuring high reliability, cost efficiency, and easy operation.

With its small footprint and reasonable structure, the ZGS transformer is ideal for urban distribution networks, as well as railway systems, solar farms, and wind power plants.

Depending on customer requirements, it can be configured as ring network, terminal, or dual power supply type. Optionally, it can be equipped with a TPC protection system, designed to handle capacitive earth fault currents in underground cables, ensuring safe and stable operation of sensitive electrical loads.

Terminal Type Pad-mounted Transformer is designed for radial power supply systems where the incoming feeder terminates at the transformer.
It features a simple and reliable structure, making it ideal for standalone loads, industrial facilities, and end-of-line distribution applications.

Accessories of Pad Mounted Transformers

1. Elbow type cable joint: Used to connect cables at an angle in electrical systems, providing a secure connection.
2. Bushing insert with well and gasket and protective cap: An essential part in electrical gear. The gasket seals, and the cap protects it from damage.
3. Bay - O - Net Fuse with dual sensors: A fuse with sensors to monitor its status and protect the electrical system from faults.
4. Four - position sidewall switch: Installed on sidewalls, it has four positions to control electrical circuits.
5. Oil level gauge: Measures the oil level in a transformer to ensure normal operation.
6. Vacuum manumeter: Measures the vacuum inside the transformer for proper functioning.
7. Thermometer: Monitors the transformer's temperature to prevent overheating.
8. Pressure release: Releases internal pressure to safeguard the transformer.
