Specification

Allowable Ampacity for 250 MCM 1C rm/16 Stranded Bare Copper Tape Shielded XLPE PE N2XS2Y 12/20KV Medium Voltage Cable: 100 Amps

About:

This cable specification denotes a medium voltage cable with a 250 MCM AWG single conductor that uses an rm/16 stranding pattern for the stranded bare copper. It incorporates tape shielding and employs cross-linked polyethylene (XLPE) for insulation with a polyethylene (PE) outer jacket. The cable is rated for 12/20KV, indicating its suitability for higher medium voltage levels compared to the 6/10KV variant.

Also Known As:

• "250 MCM AWG 1C" indicates a 250 MCM-gauge size with one conductor.
• "rm/16" details the stranding structure of the conductor.
• "Stranded Bare Copper" identifies the conductor material.
• "Tape Shielded" describes the inclusion of a shielding layer.
• "XLPE PE" refers to the insulation and jacketing materials used.
• The voltage rating "12/20KV" specifies its operational voltage capacity.

Application:

Suitable for installation mostly for power supply stations, in indoors and in cable ducts, outdoors, underground, and in water as well as for installation on cable trays for industries, switch-boards and power stations. Due to the good laying characteristics, this can also be laid easily in difficult line guideways. See DIN VDE 0298 part 1
