Power equipment
Power packages organised around the site task
Start with a single-line diagram, an equipment passport or a load description. Each task below links to relevant evidence with its actual status: supply, completed works or a historical group project.
01Substations and transformers
We package new power nodes and transformer replacements. HV/LV equipment, incoming connections and protection are coordinated; supply is distinguished from installation and commissioning.
Inputs and acceptance
- Ratings, voltages, transformer quantity and winding connection.
- Substation execution, climate, cable entries, dimensions and delivery conditions.
- Package boundaries, documentation and acceptance scope.
- For acceptance, agree the principal equipment passports or data sheets, assembly scope, identification and delivery schedule.

The completed scope covered the substation and associated network works: equipment, reserve line, installation and commissioning.
Completed work · historical reference
The ten-substation order was completed within the stated assembly and supply scope.
Switchgear and distribution boards
MV switchgear, LV distribution and incoming boards, breakers and secondary circuits. Upgrade selections must fit existing panels and protection logic.
Inputs and acceptance
- Rated current, voltage, network data and short-circuit withstand requirements.
- Diagram, incoming circuits, interlocks, controls and protection.
- Dimensions, connections and supply scope.
- Define the acceptance package: single-line and secondary-circuit diagrams, protection data and records of the agreed factory checks.

Two switchboard supplies were completed for different production areas.
Completed work · historical reference
The distribution points’ switching equipment and secondary control circuits were modernised.
Repair and replacement equipment
We identify a specific assembly from its installed model, drawing and connections. Direct manufacturer sourcing is combined with a check of installation compatibility.
Inputs and acceptance
- Manufacturer, type, nameplate, drawing and photographs of the installed assembly.
- Electrical parameters, connections and replacement constraints.
- Accessories, documentation, checks and site-work scope.
- At acceptance, check the replacement designation, connections and agreed documents. Record installation and commissioning results when those services are included in the order.

Completed work · historical reference
The substation was restored with category II power supply reliability. Imported equipment procurement and site work formed a coordinated scope.
Cables and cable connections
Cables, terminations, adapters and accessories are selected for their voltage, construction and installation conditions. Supply and site-work experience helps agree package contents, connections and a separate scope of cable-line testing.
Inputs and acceptance
- Cable type, voltage, conductor count and cross-section, length and termination.
- Equipment connection, screens, sheath and environment.
- Drums, transport constraints and required documentation.
- At acceptance, check drum identification, cable designation and lengths, termination-kit contents and the agreed manufacturer documents.

Work accepted under a transfer document · 2022
The work was completed and accepted: the transfer document describes the work and bears signatures and seals of both parties.
Historical group project
The group archive records the completed installation scope: 1,500 m of cable lines using ААБл-10 3 × 150 cable.
Fulfilment recorded in the accounting register
Electrical testing of the line was completed; payment for the order is recorded in the financial plan.
Generator sets and backup power
We agree the generating set, enclosure, controls, fuel system and load distribution. Multiple-set arrangements require separate checks of synchronisation and factory integration.
Inputs and acceptance
- Loads, starting currents, operating duty and power requirements.
- Enclosure, ventilation, heating, exhaust, fuel tank and controls.
- Tests, documents and service for the specific execution.
- For acceptance, agree data sheets and manuals, the generator, control and enclosure scope, and the conditions and records of tests specified in the order.
06UPS and battery systems
We select UPS units, batteries and replacement sets. The documented example below concerns maintenance and battery replacement in an existing UPS.
Inputs and acceptance
- Load, autonomy, phases, voltage and bypass.
- UPS model, battery type and quantity, string arrangement and space.
- Monitoring, connection and agreed service scope.
- For acceptance, identify the UPS model, battery type and count, string arrangement, agreed checks and the result of any ordered service work.
