Mobile modular substations up to 110 kV
specenergo.com
Mobile modular substations for a rated voltage of 35 - 110 kV are intended for receiving, converting and distributing electrical energy of an alternating three-phase current with a frequency of 50 Hz.
MMS are used to handle the following tasks:
• back-up of the primary equipment of the stationary substation in case of emergency power cutoffs;
• intermittent connection to the power grid of objects under construction in case of absence of electric power supply during the construction period;
• intermittent connection of consumers to the electrical power grid for the period of reconstruction of the existing stationary substation;
• load shedding of electrical power grids during peak busy hours.
