Capacitor Voltage Transformers for Outdoor Installationfrom 72.5 kV to 800 kV
-
Instrument transformers and coupling capacitors for high-frequency telecommunication systems
Characteristics:o Outdoor installationo Conformity to the main International Standardso Insulation: film(pp)-paper-synthetic fluido Mineral oil insulated electromagnetic unit contained in the transformers bottom tanko All external metallic parts in aluminium alloyo Hermetically sealed constructiono Constant accuracy in all service conditionso High fidelity of transient response and rapid damping of ferroresonance oscillationso Maintenance free
Advantages:
o No partial dischargeso Easy installation and commissioningo Long life cycle time
Suitable for:
o Carrier for high-frequency telecommunication (low-voltage terminal for H.F. coupling located inside secondary terminal box)o Line trap fixed on the top
Special Optional availables on request:
o Fuses or MCBs in secondary terminal boxo Composite Grey insulator (Standard is equipped with Porcelain Brown)o Carrier accessories (Drain Coil, Earth Switch, Surge Arrester)o Voltage Tap Grounding Switch
