Product description

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 maintenance-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, DIN 42600, ÖVE-P20, 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 for earth-fault detection 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 oder 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

Our instrument transformers can be delivered in a calibratable design for metering purposes. Type approvals for calibration are available for several countries.

We also produce current and voltage transformers in special designs and specification - we are looking forward to your inquiry!
