Changes in the temperature field of cable main insulation aging.

Cable insulation performance loss	The highest temperature inside the cable (°C)	Average temperature between two phases (°C)	Filling material temperature (°C)	The highest electric field strength inside the cable (mV/m)
Normal operations	52.01	46.95	44.01	1.1398
Loss 10%	54.02	47.89	43.98	1.1985
Loss 20%	55.98	49.01	44.29	1.4698
Loss 30%	59.03	49.58	44.39	1.8023
Loss 40%	62.97	51.08	45.03	2.0035
Loss 50%	66.96	52.02	45.02	2.1502
