Packaged transformer substations (MKTP and BKTP)

Operating conditions

The substations are designed for outdoor service under the following ambient conditions:

• Dutycontinuous
• Ambient temperature−30 to +40 °C
• Installationoutdoors
• Altitude of installationup to 1000 m
• Relative humidityup to 100 % at 25 °C
• Environmentno explosion or fire hazard
• Pollutionareas with normal pollution

Construction

A packaged substation consists of a medium-voltage section (10/20 kV), one or more transformer sections and a low-voltage section (0.4 kV). The MV and LV switchgear may share one room when the relevant requirements are met.

• The apparatus installed is new and of guaranteed quality.
• All equipment is earthed through a common earthing loop.
• Interior lighting switched from inside next to every door.
• Ventilation openings sufficient for natural cooling, protected against birds and rodents and against reaching live parts with a wire or other tool; walls and ceiling protected against condensation.
• Doors open to 120° and can be fixed open.
• Cables enter through sealed cable glands.

For normal and safe operation, every measure required by BDS EN 62271-202 and Ordinance No 3 on the construction of electrical installations and power lines is provided.

We also make concrete packaged substations (BKTP) for wind farms.

Accompanying documentation

Every substation comes with installation and operating instructions, a quality certificate, a declaration of conformity, a warranty card, a test report and all quality documents of the apparatus installed.
