GIF series are medium-voltage transformers with cast resin insulation designed for outdoor installation. They have been specifically developed for CIS countries, tailored to operate in low-temperature and aggressive environmental conditions. These support type current transformers are designed for insulation voltages from 36 kV to 40,5 kV for the mounting in outdoor medium-voltage cells, for example, at substations. They are primarily intended to transmit measurement information signals to various measuring instruments, such as commercial electricity meters, protective devices, automation systems, alarms, and control systems in AC electrical circuits of industrial frequency.
