Vertical power supply unit

摘要

The unit has modular electric current distribution sections (1), and an electric connection unit (2) for connecting the sections with compensation of dilation. A fixing unit (3) fixes the sections on an infrastructure (4). Each of the sections is presented in the form of a rigid rail with U section, where the rail is made of a synthetic material. Electric conductors are mounted in the section. The conductors have devices at their ends for cooperating with the distribution sections. U shaped opening formed at projection of the ends is provided with an elastic anti-dust device (8).
