We provide power cable and cable line installation services in tunnels and collectors.
Cable installation in tunnels and collectors plays a key role in ensuring reliable and efficient electrical and telecommunication supply. Such structures are often used to protect cables from external factors such as weather conditions, mechanical damage, and exposure to chemicals.
Tunnels and collectors provide a safe and durable solution for cable placement, which is especially important in urban environments with high building density and heavy traffic.
Project research and planning
At this stage, engineering and geological surveys are carried out, and the characteristics of the soil and existing structures are analyzed. Our specialists develop project documentation and determine cable installation routes, taking into account accessibility and site safety. An important part of this stage is also the approval of the project with supervisory and regulatory authorities.
The tunnel or collector is cleaned and prepared, with temporary lighting and ventilation systems installed. To ensure worker safety, the walls and ceilings of the structures are reinforced, and signaling and alarm systems are set up. After the work areas are prepared, materials and equipment are delivered, and cable storage and auxiliary components are organized.
Depending on the type and purpose of the cables, different installation methods may be used — cables can be suspended on special wires or fixed to dedicated cable trays. Due to the limited space in tunnels and collectors, proper work organization and minimal interference with existing utilities are crucial factors. Specialists pay special attention to the installation of cable joints, connecting, and termination devices to ensure reliable power supply.
Cables and all related devices undergo thorough inspection to ensure compliance with project requirements and safety standards. Various types of tests are carried out — including electrical insulation, mechanical load, and external impact resistance tests. Upon successful completion of testing, as-built documentation is prepared, and the system is commissioned. It is also important to organize ongoing maintenance and monitoring of the cable system to prevent potential failures and extend its operational lifespan.
