TECHNICAL SPECIFICATIONS
E-Cu or E-Al conductors are embedded in a cast resin & inert fine particle, composite insulation material. The compound has excellent dielectric properties together with high mechanical strength. It is also extremely resistant to corrosive atmospheres. The modular design of prefabricated elements allows for ease of installation. The design of the Bus bar joints allows compensation of tolerances, each element can compensate between 10 mm – 20 mm.
QUALITY ASSURANCE AND CERTIFICATION OF CAST-RESIN BUS BAR TYPE TKLC
TYPE TESTS
In addition to in house routine testing our products have undergone rigorous type testing as follows:
Cast-resin bus bar type TKLC is manufactured for low and medium voltage systems.
We use universal casting forms as well as simultaneous automated monitoring, this means we can produce an almost unlimited number of different elements for low and medium voltage systems. We can produce both standard and custom built solutions. The straight elements are made with a maximum length of up to 4 meters.
The shaped elements are manufactured in various configurations: 2-shaped, T-shaped, with bends from 90° to 170°, T-offs, elements with a double bend, custom elements, etc.
TKLC – rated voltage of up to 24 kV, rated currents up to 12 000 A. The air gaps are designed in to allow for natural cooling of the bus bar. Single or paired conductors can be used in the bus bar design. Bus bars are completed with a self-supporting screen, and holders for the bus bar support during the installation on the metal structures. Special assembly supports are also provided.
| АС | DC | |
| Nominal voltage | Up to 24 kV | Up to 33 kV |
| Nominal current | Up to 12 000 А | Up to 18 000 А |
Medium voltage system is completed with a special mesh protective screen. Bus bars for outdoor installation are completed with a climate screen.
TKLC is made of self-extinguishing materials. Both products have a very high fire withstand. The corresponding test reports and fire certificates are issued for them. Wall penetrations are fire safe. Openings, through which a current distributor runs, are filled with special noncombustible materials.
Cast-resin bus bar type TKLC can be installed in the following variations, ceiling, floor, wall, both horizontal & vertical.
The bus bar TKLC consists of separate elements. Electrical connections elements sections are carried out by means of copper (aluminum) plates which have embedded nuts. These are tightened by using high-strength steel bolts with the correct torque applied, as defined in the installation manual. After the assembly, the bolted connections are cast with the same compound with which the insulation material of the bus bar’s elements is made, thereby providing the insulation continuity through the whole length of the route.

Considering the variety of TKLC element shapes it is possible to connect the cast bus bar to any electric equipment (from the top, side or underneath):
Protective boxes may be used for protection of contact connections (degree of protection IP65 and greater). For the connection of the TKLC bus bar to other electric equipment, bus flexible connectors of various designs are used: press-welded flexibles, high-flexible braids.
To compensate the linear changes caused by thermal expansion-contraction, a special expansion element is supplied to be installed through each 35-40 m of a direct route.
