Electrical installation and commissioning works
- Installation of closed and open electrical installations up to 110 kV;
- Installation of indoor and outdoor lighting;
- Diagnostics of electrical equipment condition using modern methods;
- Modernization and design of relay protection and automation systems;
- Installation of cathodic protection systems;
- Installation of heating cables of all types;
- Design, organization, modernization, and enhancement of power supply reliability for industrial and administrative facilities;
- Supply and installation of modular mini-power stations based on diesel and gas piston generators;
- Commissioning, service, and repair work.
Power supply design involves the development of technical documentation in accordance with current architectural, urban planning, and legal requirements, while considering the specific use of the particular facility. The goal is to determine the power capacity that ensures the uninterrupted and safe operation of numerous consumers. These must be integrated into a single system using wiring of optimal cross-section and connected to the general network through protective and switching equipment.
To create a power supply design, the following data is required:
- Building and room layout plans;
- Scheme for the placement and cross-section of the incoming main line;
- Technical specifications for load placement — planned power capacity;
- Parameters for the placement of switches and outlets;
- Location for the installation of electrical panel equipment, etc.
Regardless of complexity, a power supply project consists of two parts: textual and graphical. The textual part includes a detailed description, power source parameters, justification of the selected scheme, characteristics of electrical receivers, wiring, load, and more. It also covers reliability requirements, redundancy, and other relevant data. The graphical section consists of a set of circuit diagrams, including main and emergency lighting, grounding, and placement of consumers.
