Modular and versatile: plug-in dry-type sealing ends up to 300 kV
The TFD plug-in dry-type sealing end for gas-insulated switchgear and power transformers offers maximum quality and flexibility in use. Modular and versatile configuration makes it possible to combine all kinds of polymer cable, regardless of manufacturer, with gas-insulated switchgear (GIS) and transformers for system voltages of up to 300 kV, reliably and without problems.
All dry-type sealing ends have successfully undergone type-testing in accordance with international standards IEC 60840 (<170 kV) or IEC 62067 (>170 kV). To guarantee the long-term reliability of the sealing ends, each individual silicon stress cone is subjected to a series of routine electrical tests.
