Application
Used for secondary distribution and underground service at 600 volts or less, either direct burial or in ducts. Especially suited for applications requiring superior resistance to mechanical damage. Rated 90°C continuous operation, 130°C emergency overload and short circuit 250°C.

Construction
Conductors are stranded, compressed 1350-H16/H26 aluminum, insulated with a cross-linked polyethylene meeting the requirements of ANSI/ICEA S-81-570. Neutrals are triple yellow extruded stripe and have sequential footage markers. Conductors are durably surface printed for identification. Two phase conductors and one neutral conductor are cabled to produce the triplex configuration. Conductors are also available paralleled.

Standards
Ruggedized triplex or paralleled 600 volt secondary UD cable meets or exceeds the following applicable ASTM specifications:

• B-231 Aluminum 1350 Conductors, Concentric-Lay-Stranded.
• B-609 Aluminum 1350 Round Wire, Annealed and Intermediate Tempers, for Electrical Purposes.
• B-786 19 Wire Combination Unilay-Stranded Aluminum Conductors for Subsequent Insulation.
• B-901 Compressed Round Stranded Aluminum Conductors Using Single Input Wire.

Ruggedized triplex or paralleled 600 volt secondary UD cable insulation meets or exceeds all grade and type requirements of ICEA S-81-570 and UL Standard 854 for Type USE-2.


Notes
+Ampacity: 90°C conductor temperature, 20°C ambient temperature, RHO factor 90, 100% load factor for three conductor. Triplex with neutral carrying only unbalanced load. For NEC Applications, use NEC Table 310.16 Ampacities.
