I have looked into this inquiry. I believe you have a quad shield RG6 Brightwire cable. The Brightwire (TM) indicates that the product is Brightwire which is a dry anticorrosive treatment. The 18 AWG indicates it is an RG6. The 150V indicates that the product has an NEC 830 rated jacket which means it is rated to carry power up to 150 volts.
I can tell you exactly what you have if you can answer the following quesitons:
1. Is the product you have on a reel, or in a cardboard box?
2. Is there a label on the side of the reel or box?
3. If there is a label, you should see a product description on it. An example of this would be F6SSVV BW BX (830BM).
4. If there is a label, you should see a product code on it. An example of this would be 7461004/10/A
5. You can easily determine if this is a quad shield product. Strip the jacket back like you are going to install a connector. If it is a quad shield, you will have four layers. Aluminum Braid, Non Bonded Tape, Aluminum Braid, then a tape bonded to the dielectric. These four layers indicate quad shield
The descriptions and code above are just examples, the ones listed on the label will most likely be different. Please let me know the answers to the above questions and I will try to tell you the exact product you have.
