It is assumed that the raise of temperature of the inner conductor when submitted to the maximum cu
32、rrent under nominal ambient conditions does not affect the mechanical and electrical properties of the cable (details are under study).This specification coversstandard applications. Other cables may be designed with respect to the MICE table depending upon agreement between customer and supplier.4.
