It is mainly used to supply electric power to remote mining and gas & oil industries sites where required to change the substation installation location from time to time.
- The substation is mounted on sledges with the common metalware on which the following units are mounted:
- receiving gantry of 35 kV with a 35-kV hand-operated disconnector installed on it; suspension insulators are fixed on the gantry for descending from power transmission lines and connection to the substation;
- high-voltage unit on which the following devices are installed: high-voltage vacuum switch; current transformers; and overvoltage suppressors;
- base insulator unit with a lighting installation;
- power transformer;
- auxiliary transformer unit;
- one (two) YAKNO-series outdoor complete cubicles for power supply to the end user;
- relaying equipment cabinet in which the following are arranged: power transformer protection units; 35-kV switch control unit; on-load transformer voltage control unit; and equipment for distribution of auxiliaries and heating automation.
A section for the equipment of advanced metering infrastructure (AMI) is provided for in the cabinet.
The design features and advantages of the substation are as follows:
- There is no need for preliminary construction works;
- Mobile design assembled on a single sledge allows moving the substation in a very short time;
- The substation provides for mechanical interlocks preventing erroneous actions (idiot proof) of the maintenance personnel;
- The up-to-date equipment installed on the substation implies the following: simplicity; serviceability;
- and reliability in whole.
