Transformer substations

Transformer substations are the part of the power system that transforms voltage, and they are essential to the operation of all types of buildings.

Building and installing transformer substations is one of ABM ELEKTRO's core business areas.

Although substations exist at various voltage levels, commercial and residential buildings are most often supplied by transformation from 10 kV or 20 kV to 0.4 kV. In industrial facilities, the final transformation is also to 6 kV and 10 kV, in addition to 400 V, because of high-voltage loads.

Standard secondary substation

1. MV switchgear

   Medium-voltage switchgear with the appropriate number of cells, in a separate room, usually connected to the power transformer by cable. MV switchgear

2. Transformer

   A transformer of the appropriate rating and voltage level, in a separate room (transformer box). Makitel transformers

3. LV switchboard

   Low-voltage switchboard with the appropriate number of outgoing feeders, usually opposite the MV switchgear in a separate room, connected to the transformer by copper busbars. LV switchboards

We manufacture certified medium-voltage switchgear (MV switchgear for 10/0.4 kV and 20/0.4 kV) and low-voltage switchboards (LV switchboards), and we import transformers made by Makitel Dooel from Ohrid. As a result, all three components are always available at very competitive prices.

Turnkey installation

• On-site installation of the equipment with all necessary cabling, on a turnkey basis.
• We have our own truck-mounted crane, so we also install pole-mounted substations.
• Fully equipped LV cabinets for pole-mounted substations, in aluminium, stainless steel or powder-coated steel sheet enclosures.
• Hot-dip galvanised steel brackets for supporting transformers up to 400 kVA and LV cabinets.
