15、ylene Tetra Fluoro Ethylene co-polymer (XLETFE) family for use in the on board electrical systems of aircraft operating at temperatures between 65 C and 135 C, operating at voltages not exceeding 600 V rms at sea level. This insulation system has been used in aerospace applications using 115 V (phas

16、e-to-neutral) 400 Hz ac and 28 Vdc. Verification of the suitability of cables for use in other electrical systems is the responsibility of the user. These jacketed cables are suitable for airframe use without additional protection when the jacket is present. When the jacket is stripped back the core

17、s may need additional protection. In case of conflict between this standard and other referenced documents the requirements of this standard shall take precedence. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes r
