For the same working voltage, the potential stress on the insulation is less than in case of DC system than that AC system. Therefore , a DC line requires less insulation.   In other words A DC System has a less potential stress over AC system for same Voltage level and power rating, this is why AC needs more insulation than DC system.

A.C needs more insulation than D.C because of potential stress on the insulation that is less in D.C than A.C system
