Free-standing open-pit cubicles are designed to receive and distribute three-phase alternating current voltage of 6 and 10 kV at an industrial frequency of 50 Hz and are used to connect the power supply and protect electrical equipment of powerful mining electrical consumers in distribution grids.
Climatic version of category V according to GOST 15150-69. The main purpose of ЯКНО is operating in open pit conditions, which is associated with frequent movements to different horizons along slopes, i.e. in specific, harsh operating conditions. For this purpose, a reinforced cubicle body is manufactured, which ensures the rigidity of the structure, the location of the doors creates ease of use without reducing the rigidity.
The transport stand is equipped with removable service platforms that can be removed when the cubicle is moved. The design of the device is reliable and durable.
