  7. Replacement of cable trays: DC Cables (II) * ** EDMS Id: 1213585 provided by Yann Pira ** Old cables PZK1 (1x1x240 AL ), PZK2 (2x1x240 AL ),PZM3 (3x1x400 AL) PZM4 (4x1x400 AL) – “ANTIRAD” IS23  New cables ZCR1 (1x240 AL CL.2 0.6/1kV) ZCT1 (1x400 AL CL.2 0.6/1kV) Technical appendix 362 rev. 11.5 (01.12.2004) * “ “ “ “

  8. Replacement of cable trays: 0D110 Control Cables (I) • Cables in cable tray 110 : identification in progress. • Some cables are old. • Difficult to follow in the cable trays. • No info of the use. • Cables: • C4E75: LEP TDM project, is it still alive? • NE4?: • CB50: routing not according to thecâblothèque. • NE48? Ivan Moya Martinez– EN/EL/CF – WP 31st Meeting 2014.04.08

  9. Replacement of cable trays: 0D114 Control Cables (II) • Cables in cable tray 114 : identification in progress. Ivan Moya Martinez– EN/EL/CF – WP 31st Meeting 2014.04.08

  10. Replacement of cable trays: 0D117 Control Cables (III) • Cables in cable tray 117 : identification in progress. • Difficult to follow in the cable trays. • Cables at the end of forbidden zone. (Pump system (CV), radiation monitor, emergency lights, plugs, lighting system…) • Cables entering in the ventilation pit? Red door Ivan Moya Martinez– EN/EL/CF – WP 31st Meeting 2014.04.08

  11. Replacement of cable trays: Control Cables Summary (IV) • 34 cables to re-install • Total cable length = 3701 m • 6 cables in the “forbidden zone” • Users: • Vacuum: 1 cables • RP: 1 cables • BMP detectors: 18 cables • Intercom:3 cables • Magnets: 3 cables • Telephone (sec.+normal+alarm): 3 cables • Others : 5 • BT cables not included: lighting, security lighting, AUG, pumps (CV), plugs, … • Remaining work: • 4 cables in cable tray 0D110 • 7 cables in cable tray 0D114 • Re-check cable passing to TT20/end TDC2. Ivan Moya Martinez– EN/EL/CF – WP 31st Meeting 2014.04.08

  12. New cables installation requests + temporal cable • 18 cables to install • Total cable length = 2985 m • 4 cables in the “forbidden zone” • Users: • Vacuum: 15 cables • RP: 2 cables • ABM detectors: 1 cable Ivan Moya Martinez– EN/EL/CF – WP 31st Meeting 2014.04.08

  13. Cable consolidation (I) • Near the splitter 2: • 50 or 60 new cables to pull. • No possibility to redo connectors • They will be replaced in LS2 • Best solution: wait to LS2 • Home made box (vacuum) • Redo the box in a proper place. • Home made cables to reinstall and to be included in the câblothèque.( 4 short cables) • In LS2, new cables can be installed from surface. Ivan Moya Martinez– EN/EL/CF – WP 31st Meeting 2014.04.08

  14. Cable consolidation (II) • 3 cables pulled by user up to BTV925 • Are they needed? • New cables to re-install porperly? Ivan Moya Martinez– EN/EL/CF – WP 31st Meeting 2014.04.08

  15. Cable consolidation (III) • Cable to remove: • MDFP230707: 6 cables • MDFP230710: 6 cables • Easy access • Removal up to TA801 (to be re-used in the future if it is needed) • No interference with other cables. Ivan Moya Martinez– EN/EL/CF – WP 31st Meeting 2014.04.08

  16. Magnets cables joints • 12 connections of as shown in the document (6 underMBN V071 and 6 under MBN 067) have been found. • Solution:“Manchonnage” Ivan Moya Martinez– EN/EL/CF – WP 31st Meeting 2014.04.08 • From “Magnets” Draft EDMS 1260733

  17. Time Estimations

  18. Low Voltage works • Scope: Replacement of all obsolete and non-compliant systems. • Lighting (Normal & Emergency) • Power distribution (Socket outlets) • Fixed appliances (Cranes, transport rails) • AUG buttons • Reversed sequence of installation: • Install new • Remove old James Devine – EN/EL/BT – WP 31st Meeting 2014.04.08

  19. Normal Lighting • Provide minimum 100 Lux illumination at floor level throughout TDC2/TCC2. • 50% de-rating for radiation impact on luminaires. • 58W T26 Fluorescent lighting within TDC2, long life tubes and ferromagnetic ballasts to resist radiation. • 207W LED High-bay lighting within TCC2, power converters installed in CV Mezzanine to reduce radiation dose. James Devine – EN/EL/BT – WP 31st Meeting 2014.04.08

  20. Emergency Lighting • Provide 1 Lux illumination along escape routes • 50% de-rating for radiation. • Comatelec LEDs within TDC2 and TCC2, custom radiation resistant design specific for CERN. • Additional Thorlux LED fittings installed on TCC2 catwalk for illumination of beam line bridges. James Devine – EN/EL/BT – WP 31st Meeting 2014.04.08

  21. Power Distribution • Install rationalized electrical distribution for socket outlets in vicinity of beam line • Remove obsolete equipment and cables where possible. • Agreement on positions with users required. OLD NEW James Devine – EN/EL/BT – WP 31st Meeting 2014.04.08

  22. AUG buttons • Existing cabling + buttons are life expired. • Replacement with new cables and CERN specific AUG button. • Rationalise AUG placement to minimise dose (installation and operation). OLD NEW James Devine – EN/EL/BT – WP 31st Meeting 2014.04.08

  23. Sequence of works • Pulling of new cables arriving to TT20/BA20/TDC2(4.5m) • Emergency Lighting Installation • AUG Installation • New Lighting & Power installation • EL/CF cable tray removal/installation activities • Final removal of obsolete equipment James Devine – EN/EL/BT – WP 31st Meeting 2014.04.08

  24. Conclusions • Identification must be finished. • The preparation of the work is quite advanced. • Procedure to work in safety condition must be finished (grounding) • The work in the splitter zone implies high doses • New dose survey is needed for a better calculation of the dose. • Some more work is required to reduce the total dose.
