In North America for many years conductor manufacturers assigned code words to their products to aid in identifying the different types and sizes of conductors in their catalogs, orders, etc. In some cases, these words came to be used to designate more than one conductor. In 1960, the Technical Committee on Electrical Conductors of the Aluminum Association's Technical Division initiated a study aimed at reducing the number of code words assigned to these products. The result is the system of naming that is now in place. These code words are unique and therefore remove the uncertainty around identification of a conductor and they are used worldwide.
The registration system now in place includes standard suffixes for denoting variations in construction as well as a procedure for registering code words for new conductors with the Aluminum Association. The Aluminum Association publishes a booklet titled "Code words for aluminum electrical conductors" in which most code words used in the world can be found. It's important to understand, however, that a code word is associated solely with geometry and is not a specification. The code word "Drake" for example refers to a 795 kcmil 26/7 ACSR conductor (ACSR conductors are named for birds, bare 1350 all aluminum for flowers, etc).
The five examples in your question happen to be British conductors.
Names of the Conductors?
