Ah, a husky owner with an escape artiste! Welcome to the world of Huskies!
I think you are doing a great job with a fence and putting your dog on a run for exercise. About running away - it's what they do. It requires enormous extra effort to get a Husky to recall reliably. [grin]
Any containment depends on the personality of your dog. If your dog is especially persistent, it will consistently blow through the pain of a a hidden electric fence or shock collar.
Huskies tend to be especially persistent.
See if you can test your Husky in a neighbor's hidden electric fence before you buy one and find it is useless. It may work for you or may not.
As a general rule, I would say invisible fencing is insufficient for a Husky. That is generally. It could work for your dog. An electric fence by itself is definitely insufficient for a Husky, you absolutely need some sort of physical containment or barrier
We have 4 Huskies, and two are escape artists. The others are content to laze around the 4 ft high fenced yard. We put up electric cattle fencing inside the physical fence, about 1 ft. Taht reduced the chance of anyone touching it. The physical wire fence slows them down, and the electric shock discourages them from digging under or pulling apart the wire fence. Yes, they have chewed through the welded wire fence!
Modern materials allow you to put up an electric fence in 3 hours or so. We got a solar charger, 50 plastic posts, and 1200 ft of polytape fro abut $360. Polytape and polywire is polypropylene ribbon or rope with tiny metal wire woven through it. The poles have tape-clips molded into them. We planted the polels by stepping on them. We strung the tape at two levels though the molded clips, 6 in above the ground and 18 inches above, Mounted and wired the charger. That was it. 600 ft of enclosed perimeter in 3 hours. I touched the wire and it nearly knocked me over. (I was going to experience anything I expected the dogs to try)
Any electric fence is a psycological barrier, not a physical one. I baited the dogs to touch the fence with peanut butter. They yelped and avoided it for an hour. Those darn Huskier tried it 4 more times before they were convinced. Then they tried it every few feet along the electric fence. Sheesh! They were like the velociraptors in Jurassic Park.
Your town may have regulations about electric fences, so check with town hall first. Kids always try the fences then get bored and avoid them.
Other solutions are:
higher fence 8 ft high, roller bars on top of the fence (PVC pipe strong on wires), and more grid fence laid on the ground to discourage digging.
Huskies have a wonderful joi d'vie. You will love your adopted dog, and its antics.
Here is one of many manufacurers. They explain predator fencing well. "Pet" fencing is insufficient for Huskies. Go for a modified predator fence.
