Cables will run between two of the following points: SPARO, SPARO's Breakout Box in Control Room, VIPER's Breakout Box in Control Room, Pump Shack, and Data System Cabinet. Cabling is listed by endpoints. Number of cables are listed in perentheses.
The specifications listed below are the cables that will be used to satisfy the requirements of SPARO's cabling. Some cables are already built and some cables will be built using existing VIPER cables. The rest will be ordered from Belden and the Belden catalog number is listed. All cables are PLENUM grade, TEFLON insulated wire with STRANDED TINNED COPPER conductors. All are FOIL SHIELDED and all but the 89418 and 88778 series are BRAID SHIELDED as well for additional interference screening and physical strength. The 88778 consists of INDIVIDUALLY SHIELDED TWISTED PAIRS.

Total Diam. | 0.90" | This is calculated for all cables through SPARO's cable wrap. Excludes STEPPER HEATER, VALVE HEATER. and DATA SYS CABINET HEATER CABLES. Also excludes MOTOR and SIGNAL CABLES and He-4 PRESSURE CABLE. Calculated by summing cross sectional areas and finding the diameter of a circle of this area. |
* - Motor Serial Cable is using the 18-4 conductor wire because the 3 conductor cable is not available.
