ICEA P-45-482:2007 PDF Download

The ICEA P-45-482:2007 standard provides equations and parameters for calculating the short circuit performance of metallic shields and sheaths used on insulated cables. The standard covers various types of sheaths or shields, including wires applied in different configurations (helically, longitudinally with corrugations), helically applied flat tape (not overlapped), helically applied overlapped flat tape, corrugated tape applied longitudinally, and tubular sheaths.

The standard also considers different types of cable materials that come in contact with the sheath or shield, such as crosslinked (thermoset), thermoplastic, impregnated paper, and varnished cloth. It establishes temperature limits for these materials to ensure safety.

The equations provided in the standard can be used to determine the maximum allowable short circuit current for a specific sheath/shield and short circuit duration. They can also help in determining the necessary sheath/shield size to carry a specific short circuit current for a given duration. Additionally, the standard provides information on the maximum duration a specific sheath/shield can carry a specific short circuit current.
