I am trying to figure out why my newly ran coaxial cableing wont carry a signal. I ran it down a chase, that I had previously had put in when my house was being built. The chase runs from a loft to the basement. I finished the loft and I also have 3 Romex electrical wires running down to the circuit braker box.
My question is, does the electricity ruin the Cable ( or satellite signal)

Sounds like a bad connector. Are they crimped on? Check the crimp. Remember that the sheild is also a conductor in coax and needs to have good contact with the connector.
Normal AC wiring should not cause noise on your coax.

If you are having trouble with it carying a signal make sure that the coax is properly grounded as the braided shield should block most interference from electromagnetic field from electrical wires but if it is not grounded properly it will just act as an inductor and could actually induce a voltage from the wires into your devices to where the coax is ran to.

When current flows in a wire, a magnetic field is created. This will distort some radio signals. It is possible to cross romex with coax, but it is not wise to parallel them. This is most likely the cause of your interference. You'll have to run the coax in another location.

Coaxial cable is pretty damn well shielded from outside interference. I really don't see a power cable creating enough of an electro-magnetic field to disrupt the signal. Perhaps the problem is elsewhere, is the cable pinched somewhere perhaps, that could possibly make a weak spot in the shielding that could cause problems.

I installed and repaired antennas for years--towers and roofs. The worst damage to customers homes I had ever seen was those that had grounded their antennas well. The better you ground it the more likely you will get hit. One guy had made sure to bring the ground fro his tower (surrounded by trees) into his home---attached to the electrical AND well water pipe----He lost his home---Trees were fine I had a tower that I had just installed months before that had a tree just 25' away get hammered---the transient fingers of voltage hit the tower and took out the pre-amplifier--nothing else. Not even the power supply for the pre-amp was effected. If you're gonna ground it---keep it outside!
