Study report on the TDC2/TCC2 Cabling and Low Voltage

activities

Ivan Moya Martinez– EN/EL/CF – WP 31st Meeting 2014.04.08

Summary• Replacement of cable trays– Cable trays– DC Cables– Control cables

• New cables installation requests + reinstallation of temporary cables

• Redo joints magnets cables TCC2• Consolidation of existing cables• Low Voltage refurbishment activity


Replacement of cable trays (I)


Re-routing zone (40m approx.)

Replacement of cable trays (II)

DC cables in one cable tray (0D115+0D116+0D516)Control cables in one cable tray with separator (0D110+0D114)Maintains some of the old cable trays & re-use some parts of the old cable trays.


Replacement of cable trays: 0D516 & 0D514 (III)

• Cables in cable tray 0D516 already identified (DC cables) 8 cables

• Cables in cable tray 0D514 already identified (Control cables) 17 cables


Replacement of cable trays: DC Cables (I)

Start point

Number of affected cables:a) 56 in cable traysb) 14 on the floor (+8 no accessible)

Number of joints and lugsa) Lugs : 14*2+38 =66

1) 14 short cables (link between magnets)2) 38 arrivals

b) Joints : 38+36=741) 36 for magnets in “forbidden zone”2) 38 the rest of the zone

Type of cables:a) PZK1 (1x1x240 AL ) ”ANTIRAD”b) PZK2 (2x1x240 AL ) ”ANTIRAD”c) PZM3 (3x1x400 AL) ”ANTIRAD”d) PZM4 (4x1x400 AL) ”ANTIRAD”

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?


Replacement of cable trays: 0D114 Control Cables (II)

• Cables in cable tray 114 : identification in progress.


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

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.


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


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.

Cable consolidation (II)• 3 cables pulled by user up to BTV925

– Are they needed?– New cables to re-install porperly?


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.


Magnets cables joints


• From “Magnets” Draft EDMS 1260733

• 12 connections of as shown in the document (6 under MBN V071 and 6 under MBN 067) have been found.

• Solution:“Manchonnage”

Time Estimations

Low Voltage works

James Devine – EN/EL/BT – WP 31st Meeting 2014.04.08

• 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

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.

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.

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

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

Sequence of works


1. Pulling of new cables arriving to TT20/BA20/TDC2(4.5m)

2. Emergency Lighting Installation3. AUG Installation4. New Lighting & Power installation5. EL/CF cable tray removal/installation

activities6. Final removal of obsolete equipment

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.
