ICEA S-81-570:2019 PDF Download

ICEA S-81-570:2019 is a standard that specifies the requirements for 600 volt rated cables of ruggedized design for direct burial installations. The standard covers both single conductor cables and assemblies of single conductor cables. These cables are designed to distribute electrical energy at phase-to-phase voltages not exceeding 600 volts or phase to ground not exceeding 480 volts. The cables are also suitable for use in other types of installations under normal conditions.

One of the key requirements of this standard is the use of ruggedized extruded insulations that improve the resistance of the cables to mechanical damage associated with being directly buried. The insulations help protect the cables from certain forms of mechanical damage that may occur during their intended use as secondary distribution and service cables. The standard also specifies temperature limits for the cables, with a maximum temperature of 75 °C or 90 °C, depending on the construction.
