Section 6.5.4 provides engineering information on the maximum power-handling capability (in watts) for continuous wave (CW) operation. This is the amount of power that a coaxial cable can safely transmit without overheating or developing a dielectric breakdown throughout the usable frequency range.
The safe power-handling capabilities are shown on associated curves that have been derated with assumptions including a VSWR of 2, an ambient temperature range of +38C to +71C for PE dielectric and +38C to +149C for PTFE dielectric, and a maximum inner conductor temperature of +85C for PE and +200C for PTFE.
The curves also account for the effects of typical system installations including bends, clamps, and thermally insulated sections. This is an engineering reference section rather than a test method.
