Modular Integrated Transformer Substations 6(10)/0,4 kV (BKTP).
Purpose.
Modular integrated transformer substations in a concrete casing of outdoor installation with power up to 2500 kVA are used to receive, convert and distribute electricity of three-phase alternating current with current frequency 50 Hz and voltage 6-10/0,4 kV for industrial, public, agricultural, housing objects and also cottage areas and private territories.

Operating conditions:
- height above sea-level - not more than 1000 m;
- ambient air temperature from -45°C to +40°C;
- relative air humidity +20°C – not more than 90%;
- non explosive environment free from aggressive gases or vapours, as well as industrial dust in concentrations that damage metal, protective covers and insulation elements of substation.
Structure.
- high-voltage switchgear;
- power transformer (due to the customer’s order);
- low-voltage switchgear;
- busbars provided by the modular integrated transformer substation construction.
Advantages.
· LLC SPA Sibelectroshield works out projects of modular integrated transformer substations for each costumer;
· High reliability of electrical equipment and absolute safety in use, because of using vacuum and gas-insulated switchers;
· Total operational compatibility, commissioning in 4-5 days after installation;
· Simplicity of constructions and convenience in installation work;
· Possibility to use different types of Russian or import power transformers;
· Possibility to work out an individual project for each object;
· Possibility to use different types of exterior trim, object’s color, working out the designing-projects;
· Molded case of modular integrated transformer substations, seismic resistance up to intensity 9 on the MSK-64 scale;
· Maximal operational compatibility of substations helps to shorten the installation period and the period of commissioning modular integrated transformer substations. According to the electrical schematic diagram which was chosen by the costumer the installation works of electrical equipment are done in plant conditions inside the substation, then the ready-mounted modular integrated transformer substations are delivered to the installation areas.
