A cable bus system for the mounting and positioning of high amperature, from low to high voltage electrical power cables transmitting polyphase electrical current. The cable bus system included a ventilated enclosure used to protect electrical cables mounted therein. The enclosure is provided with multiple modular cable trays which are bolted together in a stacked arrangement to form a single multi-level cable raceway. The enclosure is further provided with ventilated top and bottom covers which are secured respectively to the top and bottom of the uppermost and bottom most cable trays to define the enclosed metal circuit. The cable bus system is capable of transmitting the same highest allowable free air cable amperature in both above and underground installations, effectively improving the transmission of electrical power from one end to the other end, in installations where a transition of electrical power from below ground to above ground is either necessary or economically preferable. For the underground portion, the cable bus is installed in the encasement that is uniquely offset vented or power cooled to meet the cable high amperage requirements. The cable bus system is also suitable for high vertical rise installations when utilizing anti cable slip mechanism or technique.

Embodiments generally relate to long-distance, 3-phase, AC electricity transmission structures. In one embodiment, the structure comprises an array of beams, the array comprising a sub-array of 3N active beams, wherein N is an integer, one passive beam on the right side of the sub-array of active beams; and one passive beam on the left side of the sub-array of active beams. The centers of the cross-section of each of the active and passive beams lie in a single plane. In another embodiment, the structure comprises an array of 3N metal active beams, wherein N is an integer; and a tunnel of rectangular cross-section with either 90 degree or rounded corners. The array of beams is mounted within the tunnel, and the two side walls of the tunnel are lined with a highly conductive metal having a thickness similar to the thickness of metal used in the active beams.

The invention relates to a modular and compact arrangement (200) of three phases (A, B, C) of a gas-insulated apparatus (100), that is suitable for placement inside a tunnel or a pipe (106) or another confined space. According to the invention, the three phases (A, B, C) are arranged in a triangle or side-by-side on a fixation part (103, 104) which includes a roller system (105; 105a, 105b, 105c, 105d). This allows the insertion of such a three-phase assembly (100) into confined spaces such as pipes or tunnels (106), without the need for access by workers or machinery. Furthermore, the present disclosure relates to a method for assembling and installing such a three-phase arrangement (100) into the confined space (106).
