Situated around Plovdiv, Holding KCM 2000 is one of the most significant industrial holdings in Bulgaria. As the largest lead and zinc production company in Southeastern Europe, the complex integrates in an innovative way a 60-year tradition in metallurgy and more than 70 years of experience in mining and enrichment. The scale of production, which is used to supply industry leaders throughout the world, requires an extremely high degree of energy security. For the processes of pouring lead, zinc and precious metals such as gold and silver to function smoothly, it is necessary for the power infrastructure to be more than just reliable.

This task falls into the territory of Engineering EAD, part of the Filkab group. The organization has rich experience in designing complex energy solutions and is an established name in the sector. The energy supply project at the industrial site includes several complex engineering operations, which need to guarantee complete stability during continuous loads. The primary focus is the construction of new 6 kV underground cable lines - the backbone of the energy system, connecting important production nodes in the enterprise with the medium voltage transmission network.

The process requires precise planning and installation, including setting up cable lines for medium (СрН) and high voltage (HH). The specifics of the location and the high requirements for safety and sustainability of the holding puts a focus on materials that are durable and with a long exploitation life.

"Work on a site of this scale requires great attention to technological consistency. Each route and each connection are designed to accommodate both the current large production needs and to provide the necessary reserve for future technological modernizations," Engineering EAD commented to BalkanEngineer.com.
