Abstract
A preformed block is used for housing and routing electrical power cables, and comprises a central cavity. At least two adjacent faces of the block have an opening which connects to the central cavity. Electrical power cables can thus be routed within the block between those openings, from a side face (leading to a trench) to the top face (leading to an electrical installation on top). There is also provided an electric vehicle charging station using the precast block and a method of casting a block.

A preformed block for housing and routing electrical power cables, comprising:
- a central cavity (1);
- a first face (2) having a first opening (20) connected to the central cavity by a first conduit (21), and having a first part of an integrated fastening arrangement (22) to enable an adaptor plate to be fastened over the first opening;
- a second face (3) opposite the first face, having a second opening (30) connected to the central cavity by a second conduit (31);
- and
- a side face (4,5,6,7) extending between the first and second faces,
- wherein the side face has a side opening (40,50,60,70) connected to the central cavity by a side conduit (41,51,61,71) adapted to receive an electrical power cable or a cable duct to be housed within the preformed block between the first opening and the side opening, and
- wherein the side opening and the second opening extend to an edge of the preformed block disposed between the side face and the second face, such that the side conduit and the second conduit, together with the central cavity, form a continuous cavity, and wherein the first opening and the first conduit each have a minimum dimension of 10 cm.
