In response to a problem encountered in the field, the Approval and Certification Center initiated a program to develop models which enable computer calculation of conductor temperature rise versus time in trailing cables. To date, a common model equation has been developed and parameters determined for two round trailing cables typically used on continuous miners, Type G-Gc, sizes 2/0 AWG and 4/0 AWG, rated 90{degrees}C. The resulting cable models have been tentatively confirmed in laboratory trials using repetitive four-level constant current cycles and triangular currents in which the peak current varied on succeeding cycles. Model refinement and additional laboratory trials are projected using randomly varying current, simulating actual current conditions in mine trailing cables. Contingent on success here, trials on an operating continuous miner will follow.
