It is a random, and will also happen if raiders come from other powers. The larger number of raiders, the higher the chance for an intercept.

Considering the frequency that my deepest interior trade sectors get raided - the frequent random event theory seems likely. And, in that event, it means that all trade sectors would require a certain level of defense.
Everything I've raid says that it isn't cost effective to patrol the freighter sectors with ships. Your chance of an intercept depends on how many raiders are there and how many ships you have (they're divided by the number of trade routes), making it pretty ineffective (it seems).
If you were going to patrol routes, you want fast ships on the trade routes, and I'd put them on trade routes near borders.
I don't know how most people do this, but my trade exceeds planetary income. I go freighter crazy, as it funds my war machine quite well.
