Gel filled RUS cable corresponds to which standard code?
Correct Answer:
PE86
Explanation:
In this case, the standard code used for identifying cables is the RUS designation system, where a prefix like PE is followed by a two-digit code that denotes the specific construction and filling of the cable. Gel-filled RUS cables are classified under the PE86 code. That suffix encodes the gel-filled moisture-protection construction defined by RUS for that type of cable, ensuring it’s the correct match for gel-filled, moisture-resistant designs used in underground or duct environments. The other codes correspond to different cable constructions or filling methods and don’t match the gel-filled category, so they wouldn’t be correct for a gel-filled RUS cable.
