TKLS cable buses
The TKLS bus duct is equipped with special aluminum "self-supporting" screens mounted on the side surfaces of the bus duct. These screens are designed for attaching the bus duct to metal structures, walls, floors, and ceilings, and also serve as grounding for the bus duct. Protective screens made of perforated aluminum sheets are installed in the grooves of the "self-supporting" screens at the top and bottom. It is recommended to install protective screens on bus ducts in areas accessible to touch. To protect the bus duct from precipitation, a climatic screen is installed on top instead of the protective screen.

TKLN busbars
The uniqueness of TKLN busways lies in the direct encapsulation of parallel copper or aluminum busbars with a rectangular cross-section in insulating material, which is a special compound produced by casting and saturated with fine-grained inert particles. The compound provides excellent dielectric properties, high mechanical strength, and specific physical characteristics. At the installation site, all busway section connections are filled with this compound, ensuring continuous insulation along the entire route. The design of the section joints also compensates for construction deviations.
TKLN busways with cast insulation are used in residential high-rise buildings, industrial facilities, shopping complexes, business centers, offices, train stations, and similar locations. These products are designed to operate at ambient temperatures from –60 °C to +55 °C, with a service life of at least 30 years.
