The cells are intended for repair purposes and replacement of previously manufactured switchgears that provide power supply for electrical equipment of rotary complexes of quarry excavators installed in branch networks of quarries, as well as in places of connection to internal quarry overhead power lines with voltage up to 10 kV.
The cells are used to repair and replace previously manufactured switchgears that provide power to the electrical equipment of the rotor complexes of mining excavators, as well as in places of connection to internal power transmission lines of voltage up to 10 kV.
The main purpose of YAKNO is exploitation in a career, i.e. in specific, evaluative operating conditions. To this end, cell’s body is reinforced to provide structural rigidity. The design of the device is reliable and durable.Reference designation YAKNO–10–Х–ХХ:
