ICEA P-45-482:2013 PDF Download

The standard ICEA P-45-482:2013 provides equations and parameters for determining the short circuit performance of metallic shields and sheaths on insulated cables. It covers a range of materials such as aluminum, bronze, copper, lead, steel, zinc, and cupro-nickel alloys. Different types of sheaths and shields are considered, including wires applied in various ways (helically, longitudinally with corrugations), helically applied flat tape (overlapped or not), corrugated tape, and tubular sheath.

The standard also takes into account the types of cable materials in contact with the sheath or shield, including crosslinked (thermoset), thermoplastic, impregnated paper, and varnished cloth. Additionally, it specifies temperature limits for different coverings and insulation materials to ensure safety.

The equations provided in the standard can be used to determine the maximum short circuit current permitted for a specific sheath or shield and the duration of the short circuit. They can also be used to calculate the size of the sheath or shield required to carry a specific short circuit current for a given duration. Furthermore, the standard helps determine the maximum duration a specific sheath or shield can carry a specific short circuit current.
