Determining thermal stress in cables and conductors

SpletIN THIS EXAMPLE THE Ft EQUALS 170,472.22 N/m. Ft is a force in Newtons per metre so to calculate the maximum force which each cable cleat restrained, this must be multiplied by the cable cleat fixing centres: Max force per cable cleat = Ft (N/m) x fixing centres (m) Max force per cable cleat in this example (0.3m fixing centres) = 51,141.67 N. SpletPower loss in cables is strongly dependent on frequency: the greater the signal frequency, the more severe the power loss per unit cable length. REVIEW: Standard cables exhibit infinite ohms (no current) between conductors in a disconnected cable. Likewise, standard ideal cables exhibit 0 ohms of resistance through each conductor from end-to-end.
