IS 10241 : Part 2 : 1982 Electrical cables for aircraft: Part 2 Pren type electric cables

1. SCOPE

1.1 This standard (Part II) specifies the requirements and test for 'Pren' type cables for aircraft wiring of circuits where the voltage between conductors, or between a conductor and metal braid or the aircraft structure does not exceed 600 V rms and the frequency does not exceed 1600 Hz. These cables are suitable for any combination of ambient temperature and conductor current for continuous service not producing a stabilized conductor temperature which exceeds 90ºC. These cables are also suitable for fixed wiring in aircrafr when low temperatures up to-75ºC are encountered, but are not suitable for severe flexing below - 40ºC.

1.2 These cables do not support combustion.

1.3 These cables are not suitable for use without additional protection in areas where ester based fluids are present.
