6-10kV Single-phase voltage transformers ОЛС, ОЛСП type

6-10kV Single-phase voltage transformers ОЛС, ОЛСП type

   The ОЛС, ОЛСП type transformers are designed for power industry and used for feeding a partitioning power items and automatic transfer switch (ATS) on 6-10 kV electric grids. Also, these transformers are components and intended for use in the complete switchgear (КРУ) for outdoor installation and can be used in AC electrical  frequency of 50 Hz or 60 Hz exposed to lightning surges, in conventional lightning protection measures, for power measurement, protection, automation, signaling and control circuits.

    The ОЛСП transformers feature is built-protective signaling safety device.
