  1. RPC (Barrel) Cabling summary

  2. Signal cable specifications • Signal Cables (two possibilities): • Loose pair round and twisted pairs (with flat zone for crimping connector); (made by Amphenol) • Round and twisted pairs (no flat zone) (made by Kabelwerk) • The choice will depend on the price including manufacturing

  3. HV cable specifications • Cable from KERPEN suitable to sustain up to 20 kV • Cable characteristics: • In compliance with CERN safety instruction IS 23 • Single conductor- = 0.16 mm • Conductor resistance @ 20°C = 147 /Km • Core- = 3 mm • Screen wire-=0.2 mm (for 10 conductors) • Overall diameter = 8.4 mm (for 3 conductors) • Price: 1.050 €/Km (for 10 Km and 3 conductors cable)

  4. LV cable requirements • 8 conductors cable (=1mm) • Rated current/conductor = 3A • Aluminium/mylar shield • Sheath made by LSZH flame retardant and fire resistant material, halogene and sulphour free specification requested by Cern Safety Instruction IS23 (coloured in blue as requested) • Total cable diameter = 9.6 mm

  5. Cables quantity and occupancy (Barrel) • (Medium Voltage – Communication Link: from RB to Controller SY1527 • 13 LB x 10 sectors (30° each) + 15 LB x 2 sectors (sectors 4 & 10) • We prefer 7 instead of 6 for a better distribution in RB2 divided by three case
