Underground Paper-Insulated Lead-Covered Cable Fault Indicator

SEL-PILCs are applied on paper-insulated lead-covered cables (PILCs) in underground distribution systems. The SEL-PILC is compatible with single-phase triplexed and three-phase sector (or round) PILCs from 2.2" to 4.64" in diameter.

The SEL-PILC’s split-core design is quick and easy to install without disconnecting the cable. Its rugged construction is designed for submersion in up to 15 feet of water. The SEL-PILC is compatible with the RadioRANGER Underground Wireless Fault Indication System. Used together, they make fault-finding on urban systems as simple and quick as possible.

Easy Installation and Use—Apply SEL-PILC Fault Indicators along segmented PILCs to effectively locate faults without the need to separate or disconnect the individual phases of the cable. Optimize fault-finding time with four- or eight-hour automatic timed reset.

Cost Efficiency—As the segmented cable is gradually replaced with triplex nonlead cable, apply the same fault indicators to the triplexed bundle to effectively locate faults.

Versatility—Install SEL-PILCs in metropolitan areas, airports, universities, and industrial sites to quickly locate faults. When these fault indicators are used in conjunction with the RadioRANGER System, there is no need to open, enter, pump, or drain multiple vaults or manholes to determine the fault indicator status. Troubleshooters can use the information displayed on the remote fault reader to find the faulted cable section, in many cases without leaving the truck.
