    3. Where possible, jumper cable connections to sensor cable should be made within the monitored area. PermAlert recommends the use of OZ Gedney cord grips installed as shown in Figure 7. Cord grips must clamp only jumper cable or TFH cable. The outer braid on TFH cable must be pulled back so the cord grip is located on the smooth outer jacket.

  • Page 16: Junction Boxes

    3 Installing Jumper Cable Junction Boxes 1. Locate and install all junction boxes before installing any cable. Locate junction boxes as indicated on system drawings or as required. These locations include calibration points, the start and end of cable runs, manholes, probes, etc. Care must be taken to prevent water from contaminating these areas.

  • Page 17: Cable Installation In Secondary Contained Piping

    Because the sensor cable is placed on the bottom of the air space, there must be a continuous unobstructed passage for the cable(s) being pulled into the system. PermAlert recommends a 1" air space. Pipe support design and alignment is critical. Pipe supports and other surfaces that the cable may come in contact with during “pulling”...

  • Page 20: Cable Splices

    4 Cable Installation Cable Splices Continuous pull rope and sensor cable are "pulled" into the secondary containment during certain stages of installation. Several splices are used to provide secure attachments to pull ropes and cable during this procedure. The following methods are recommended for splicing. Note: When using tape to seal the splices, use only PVC electrical tape.

    PAL-AT Installation Manual 4.3.2 Wire Rope to Wire Rope Splice Step A Extend 12" to 18" of each wire rope end for the splice. Step B Unravel each of the 12" to 18" ends into a 3 strand and a 4-strand section (approximately 50% in each), keeping the adjacent strands together.

    PAL-AT Installation Manual 4.3.4 Wire Rope to Leak Detection Cables The following steps apply in general to all sensor and jumper cables. However, there may be slight variations to the steps presented depending on the cable selected. For example, the jumper cables have an outer jacket but no plastic overbraid, while the TFH cable has both a jacket and an overbraid.
  • Page 24 4 Cable Installation Step F Cut 5" off the exposed end of the sensing cable. Step G Cut off 15"-18" of the outer jacket and tightly tape the edge of the outer jacket to the metal overbraid. (applies to TFH and jumper cables only.) Step H Slide 12"...

  • Page 25: Installation Of The Continuous Pull Rope

    The finished splice should be tapered in appearance. Installation of the Continuous Pull Rope 1. PermAlert recommends the installation of a continuous pull rope, free of splices between properly located and accessible pull points. 2. All sections of factory-prefabricated piping should be supplied with a factory-installed pull rope. The factory-installed ropes shall be used to pull the continuous pull rope into the air space before the secondary containment field joint closures are completed.
  • Page 26 4 Cable Installation 3. Pulling the continuous pull rope into the air space of the secondary containment requires careful planning on the installer’s part. Care must be taken during the installation of the pipe system to proceed in a manner that will maintain accessibility to the factory installed pull rope. 4.

  • Page 27: Installing The Sensor And Jumper Cables

    Care must be taken during installation of sensor cable to avoid contact with potential contaminants such as water puddles or oil. 2. PermAlert recommends installing the sensor cable before backfilling of underground secondary contained pipe systems.

PermAlert Cathodic Blocking Package includes a nonmetallic NEMA 4X junction box and one set of cable connector assemblies. To install it, mount the junction box and route jumper cable making cable connections as shown in Figure 12.

    It also absorbs moisture from the air if the air is saturated or near saturation. PermAlert recommends a maximum of 80% relative humidity, keeping in mind that the relative humidity will increase if the temperature of the air or a surface in the airflow decreases. In subfloor applications, care must be taken to make sure the cable is not located directly in the airflow where localized higher humidity or saturated air is present.
