1 C-side VFE-FE: PS cabling Overview Rustem DZHELYADIN (CERN&IHEP, Protvino) Cable trays design: 1.PS-top cable tray 2.PS/SPD lateral cable tray 3.PS/SPD bottom cable tray 4.Possible alternative solution Cable routing for PS-top at critical section 1.Chariot - Cable Chain (CC) Junction 2.Bottom cable tray section (under study) Temporary Reel Storage at the platform Passerelle suspension production The straight of CC 2 C-side VFE-FE: PS cabling PS-top cable tray Rustem DZHELYADIN (CERN&IHEP, Protvino) 3 C-side VFE-FE: PS cabling PS-top cable tray Rustem DZHELYADIN (CERN&IHEP, Protvino) S=1,5mm A=11-12mm D=8mm W=45kG CHF=250 Production=welding? drilling, bending Main concern = how to attach cables 4 C-side VFE-FE: PS cabling PS-top cable tray (alternative solution) Rustem DZHELYADIN (CERN&IHEP, Protvino) l=600mm L=12m Nl=7x620mm=4340 (4356) H=60mm W=30kG CHF=200 Production= screw & nut, cut No reinforcing bar Two layers fit within 50mm height Easy to mount Main advantage = easy attach cables 20mm 5 C-side VFE-FE: PS cabling PS-lateral cable tray Rustem DZHELYADIN (CERN&IHEP, Protvino) S=1,6mm W=44kG CHF=order ref. Production= a) welding? b) milling? Main concern = how to attach cables Perforated steel 52mm 8090mm 507mm 100mm 6 C-side VFE-FE: PS cabling PS-lateral cable tray (alternative solution) Rustem DZHELYADIN (CERN&IHEP, Protvino) l=500mm L=9m H=60mm W=30kG CHF=122 Production=screw & nut, cut More that two layer fits within 50mm height Main advantage = easy attach cables low weight 20mm 7 C-side VFE-FE: PS cabling PS-bottom cable tray (alternative solution) Rustem DZHELYADIN (CERN&IHEP, Protvino) l=400mm L=5m H=100mm W=15kG CHF=~80 Production=screw & nut, cut Main concern = delivery time? Not all dimensions available at CERN Store Main advantage =easy attach cables low weight 8 C-side VFE-FE: PS cabling Chariot CC Junction Rustem DZHELYADIN (CERN&IHEP, Protvino) Directly to CC Outer CC Chariot SM1SM2 SM3SM4 Main aim exclude crossing 9 C-side VFE-FE: PS cabling Reel storage at platform Rustem DZHELYADIN (CERN&IHEP, Protvino) Cables to CC Random access regardless cables Dense packing 108 reel per 2x1.5m 2 Low weight ~30kG Rigid up to 1 ton load Easy assembly cut & screw 10 C-side VFE-FE: PS cabling Passerelle suspension Rustem DZHELYADIN (CERN&IHEP, Protvino) Drawings verified (except few holes) Material available Machining started To be ready by Monday noon 11 C-side VFE-FE: PS cabling The straight of CC Rustem DZHELYADIN (CERN&IHEP, Protvino) Small effect after ton few cm less/20cm applied at 7.5m arm May be useful: -long-term training -larger weight to apply Result contradicts to what provided by producer More tests required
