Rapid growth in the urban development sector raises the issue of electric power delivery to end users in dense urban planning environments. Given that construction of overhead power lines in cities is extremely complicated and sometimes even impracticable, installation of cable lines is the best power transmission alternative. Cable lines can be buried directly in ground, laid in cable channels or pipes, installed on the supporting structures or laid underwater. In practical terms, cable lines can be installed under almost any conditions.
Cable lines offer a number of benefits, including:
Structum construction company offers installation of cable lines up to 220 kV utilizing innovative techniques, appropriately selected equipment and high-quality materials. Structum uses innovative equipment by OMAC and TESMEC for the construction of underground power transmission networks. We use cable products with extruded high-temperature insulation (of cross-linked polyethylene and ethylene propylene rubber) from both Ukrainian and global manufacturers in the construction of power transmission cable lines.
Design and engineering of cable lines is the initial stage of the construction process. It involves the following steps:
Cable line construction is started after issuance of design and estimate documentation and obtaining of the expert report. Direct burial is the most cost-effective and technically simple cable line installation method, which includes the following stages:
All construction stages – from design of a cable line to its commissioning – are carried out to a high professional standard, in compliance with the requirements of relevant regulatory documents and within the specified time frame. Having highly qualified staff, special-purpose machinery and equipment, we are ready to perform any kind of construction, installation, maintenance and start-up works.
Maintenance or restoration of cable lines is generally needed in the event of physical wear or deterioration of materials, exposure to mechanical stresses or when a higher current capacity is required.
Structum offers a full package of cable line maintenance and restoration services:
Maintenance and restoration of cable lines are carried out in accordance with the project documentation, which is developed based on the test data, results of the survey and assessment of the general condition of the cable line.
