Concentric Cable
DESCRIPTION
Concentric cables are designed for service entrance and feeder applications, featuring a central conductor surrounded by neutral conductors, often insulated with XLPE, PVC, or PE. These cables are UL854 and/or UL44 certified, supporting safe and reliable electricity transmission in residential, commercial, and industrial power systems. Typical configurations include copper or aluminum alloy conductors, rated up to 600V, and suitable for direct burial or overhead installations.
APPLICATION
The concentric cable is used as electric service entrance from the power distribution network until the meter panel (especially where it is required to prevent "black" losses or electric power robbery), and as feeder cable from the meters panel until the panel or general distribution panel, just as it is specified in the National Electrical Code. This type of conductor can be used in dry and wet places,directly buried or outdoors;its maximum temperature of operation is 90 °C and its voltage of service for all the applications is 600 V.
