Cables and chicane mock up
What we would like to define or test with the mock up:
• if the installation (of both cable trays and cables in the trays) will be possible• cable packing factor in the corners (curves) of the chicane passage• maximum bending radius of the cables we will install• may be define a relation between the bending radius and the packing factor at the critical position• test if the installation of cable ducts (metallic or plastic) in the cable trays is feasible
