Outdoor Voltage Transformers

Outdoor Voltage Transformers with Cycloaliphatic Cast Resin Insulation 12 - 36 kV

The voltage transformers series EGF (single-pole insulated) and ZGF (double-pole insulated) are mainte- nance-free cast-resin transformers for outdoor application and system voltage Um up to 36 kV.

They comply with various national and international standards (IEC 60044-2, VDE 0414, ANSI, GOST etc.).

The Voltage Transformers are designed for ambient temperatures from -40°C up to +50°C and for operation up to 1000m
above sea level (>1000m on request).

Single-Pole Insulated Voltage Transformers:

- secondary 100/√3 V or 110/√3 V

- accuracy classes 0.2, 0.5, 1, 3, 3P and 6P

- winding f. earth-fault det. on request (100/3 V or 110/3 V)

- voltage factor 1.9 x Un for 8 hours

- frequency 50 Hz or 60 Hz

Double-Pole Insulated Voltage Transformers:

- secondary 100 V or 110 V

- accuracy classes 0.2, 0.5, 1, 3

- voltage factor 1.2 x Un or 1.5 x Un

- frequency 50 Hz or 60 Hz
