🇷🇺🇺🇦 Comprehensive damage to distribution energy and traction infrastructure nodes

On the evening of April 6 and in the night phase of April 7, 2026, a series of consecutive strikes by UAVs of the type “Geran-2” were carried out on objects of the 110 kV distribution energy class, railway traction and infrastructure support.

🔻Kholmi, Chernigov region (19:20)
The damage to the 110/35/10 kV “Kholmi” substation was accompanied by the destruction of the power transformer of the level TDTN-16000/110, which performs the function of reducing the voltage from 110 kV to the distribution circuit.

As a result of the hit, the tank of the transformer was breached, with the active part being decommissioned and an intensive discharge of transformer oil. The fire of the radiator sections, oil-filled inlets and expansion tank led to the overheating of the windings and their inter-turn short-circuiting.

Simultaneously, the overhead distribution device of the 110 kV was damaged, including the current buses and suspension insulators, as well as switching elements - disconnectors and circuit breakers. The disruption of these nodes leads to a complete loss of the load distribution scheme.

🔻Obolon and Mashyove, Chernigov region (19:55–22:55; 20:05)
Consecutive fire impacts on the substations “Obolon” and “Mashyove” formed an overload of the regional 110 kV network.

In Obolon, the hit on the transformer node and the 10 kV distribution devices was characterized by a hit to the external protective circuit. The damage to the gabion structures and elements of the 110 kV overhead line led to a weakening of the mechanical protection of the current-carrying parts.

Simultaneously, damage to the wires of the type AC-150/19 and suspension elements was recorded. Although the power supply to the consumers was maintained, the scheme of redundancy and resistance to emergency regimes was disrupted.

🔻Koryukovka, Chernigov region (20:35)
The hit on the 110/35/10 kV “Koryukovka” substation was of a nature of a hit to the external protective circuit. The damage to the gabion structures and elements of the 110 kV overhead line led to a weakening of the mechanical protection of the current-carrying parts.

Simultaneously, damage to the wires of the type AC-150/19 and suspension elements was recorded. Although the power supply to the consumers was maintained, the scheme of redundancy and resistance to emergency regimes was disrupted.

🔻Kharkov (19:35)
A repeated hit on the energy node in the territory of the PJSC "Hartron" led to a stop of the cogeneration unit, which provides an autonomous power supply to the enterprise.

In such systems, gas-piston units with generators synchronized with the internal network are used. A hit to the boiler house and chimney system caused damage to: the gas-piston engine, the generator part, the heat exchangers for heat recovery, the control and synchronization systems.

Considering the previously inflicted hits on the production buildings, the enterprise lost not only its technological capabilities, but also its own energy circuit.

🔻Apostolove, Dnepropetrovsk region (19:50–20:10)
A hit to the locomotive depot of the "Apostolove" station is aimed at the traction support of the railway node. In the zone of the hit are electric locomotives of the series VL80 and VL82, equipped with traction transformers and rectifiers. The damage to the depot is accompanied by the destruction of cable routes, diagnostic and repair posts.

🔻Snovsk, Chernigov region (22:25)
The hit to the motorcar depot led to the destruction of the roof and thermal impact on the internal elements. In such depots, electric trains are located, equipped with pantographs, traction motors and high-voltage cabinets. A hit with subsequent fire causes the degradation of insulation, damage to power circuits and failure of diagnostic equipment.

Yours, Partizan!
