Unitized transformer substations are one-transformer substations for outdoor installation and are intended to receive electric energy _ three-phase, 50 Hz a.c. of 6 or 10 kV, to convert it into 0.4 kV for energy supply in moderate climatic conditions (from -45o C to +40o C). ÊÒÏ substations can be equipped with air (overhead) or cable input/output leads in various combinations. When air lead-in is used, ÊTÏ is connected to transmission line through disconnecting switch (included into ÊÒÏ delivery set) which is mounted on the transmission line nearest tower. ÊÒÏ outgoing lines are fitted with stationary automatic circuit-breakers. High-voltage fuse cartridges are located inside ÊÒÏ cabinet. ÊÒÏ has function of active power consumption metering. ÊÒÏ is equipped with electrical and mechanical interlocking ensuring safety of attending personnel. ÊÒÏ has exterior lighting feeder with automatic ON/OFF function. To maintain normal operation conditions for low-voltage gear, circuit design provides heating function
