APPLICATIONS
PowerGuard® cables are intended for use in wet or dry locations for distribution of single or three phase medium voltage power. These cables may be installed in ducts, exposed to sunlight or direct buried.

CONSTRUCTION
Single conductor cable with filled strand copper conductors, true-triple extrusion, dry cured insulation system consisting of a thermosetting semiconducting conductor shield, high dielectric strength PowerGuard® tree-retardant crosslinked polyethylene (TR-XLPE) insulation, thermosetting semiconducting insulation shield, copper concentric neutral wires, water blocking agents, black encapsulating linear low density polyethylene (LLDPE) jacket.
Conductor:
Compressed concentric stranded copper. Stranded conductors are water-blocked with conductor filling compound.
Conductor Shield:
Extruded thermosetting semiconducting cross-linked polyethylene (XLPE) shield which is free stripping from the conductor and bonded to the insulation.
Insulation:
Extruded, Tree-Retardant Crosslinked Polyethylene (TR-XLPE) - 100% insulation level.
Insulation Shield:
Extruded thermosetting semiconducting cross-linked polyethylene (XLPE) shield with controlled adhesion to the insulation providing the required balance between electrical integrity and ease of stripping.
Metallic Shield:
Solid bare annealed copper wires helically applied and uniformly spaced.
Water-blocking agents:
Applied over the insulation shield and around the concentric neutral wires to resist longitudinal water penetration. Longitudinal water penetration shall be tested in accordance with the latest edition of ICEA T-34-664 except that the minimum requirement is 15 psig for 1 hour.
Outer jacket:
An extruded-to-fill black non-conducting linear low density polyethylene (LLDPE) jacket, meeting the physical requirements of Table 1, below, when tested by the methods specified in ANSI/ICEA S-94-649. The jacket shall be free-stripping and not interfere with an intimate contact between the neutral wires and the underlying extruded insulation shield. The jacket is sunlight resistant and marked. The jacket shall contain a print legend marking, sequential length (meter or feet) marking and three longitudinal extruded red stripes.

STANDARDS
These cables are manufactured and tested to meet or exceed the following standards:

• ASTM B3 – Soft or Annealed Copper Wire
• ASTM B8 – Concentric-Lay-Stranded Copper Conductors, Hard, Medium-Hard, or Soft
• ICEA S-94-649 – Concentric Neutral Cables Rated 5 Through 46 kV
• ICEA T-31-610 – Test Method for Conducting Longitudinal Water Penetration Resistance Tests on Blocked Conductors
• ICEA T-34-664 – Test Method for Conducting Longitudinal Water Penetration Resistance Tests on Longitudinal Water Blocked Cables
• ICEA P-45-482 – Short Circuit Performance of Metallic Shields and Sheaths on Insulated Cable
• AEIC CS8 – Extruded Dielectric, Shielded Power Cables Rated 5 Through 46 kV
• UL 1072 – Medium-Voltage Power Cables

LISTINGS AND CERTIFICATIONS
• UL listed as Type MV-90 – File E476447

NOTES
1. Dimensions and weights are subject to standard manufacturing tolerances and are subject to change without notice.
2. Cables are manufactured, tested and marked to meet or exceed the requirements in ANSI/ICEA S-94-649 for concentric neutral cables rated 5-46 kV and the latest revision of AEIC CS8.
3. Migration of soil moisture away from the cable is more likely at the higher operating conductor temperature and can result in an increase in soil thermal resistivity, resulting in an increase in conductor and soil temperature.
