Product Description

                                                                                            GAS-INSULATED TEST TRANSFORMER

The Gas-Insulated Power Frequency Transformer uses SF6 gas as the insulation medium. It provides excellent dielectric strength, ensuring safe operation in space-constrained areas. It integrates the functions of potential transformers and test transformers.

The equipment consists of a front switchgear, a YDQW - 300/300 power frequency test transformer (installed in a container tank), a TYDZ - 100/0.38/0~1.1 column - type voltage regulator, an LBQ - 100/1 filter, a GK - 300/1 compensation reactor, a damping device, a TAWF - 500/300 capacitive voltage divider (installed in a container tank), and a PLC control device.
