Quadruplex Service Drop ANSI/ICEA S-76-474

Quadruplex Service Drop Cable to ANSI/ICEA S-76-474 hangs from its bare neutral, which also serves as the return conductor. The main data are summed up below; every code word is listed in the TDS tab.

Technical Characteristics

Ordering Information

Please state the code word or the phase size, neutral type and size; the quantity and length per reel; and whether the optional conductor identification legend is wanted.

Aluminium 1350 Phase Conductors, XLPE Insulated, with ACSR Neutral

Aluminium 1350 Phase Conductors, XLPE Insulated, with Aluminium Alloy 6201-T81 Neutral

* Code words marked with an asterisk are listed as built and fall outside the ANSI/ICEA S-76-474 tables: their insulation thickness, neutral size or neutral stranding does not follow Table 3-1, Table 2-6 or Clause 2.3.1. They are not offered as S-76-474 constructions.

Phase conductors of 1 AWG and 300 kcmil are listed as built; Table 2-6 of the standard gives no neutral size for these phase sizes.

Conductor Tests

• In accordance with ANSI/ICEA S-76-474 Clause 2.7.1, dc resistance is measured to an accuracy of 2% or better and corrected to 25 °C.
• In accordance with ANSI/ICEA S-76-474 Clause 2.3.3, a strength test on the neutral taken from the finished assembly is made only when agreed at the time of order; the neutral then breaks at no less than its rated strength in the free length, or no less than 95% of it inside or within one inch of a grip.

Insulation Tests

• In accordance with ANSI/ICEA S-76-474 Clause 3.4.1, insulation resistance at or corrected to 1000 ft and 15.6 °C is not below the value set by an IR constant of 10,000 for 90 °C insulation.
• In accordance with ANSI/ICEA S-76-474 Clause 3.4.2, each finished length passes either 3000 V ac for one minute between phase conductors and water after 30 minutes immersion, or a spark test of 8.5 kV ac or 13.0 kV dc with the neutral isolated.
• In accordance with ANSI/ICEA S-76-474 Clause 3.5.1, the minimum insulation thickness at any point is not below the Table 3-1 value.
• In accordance with ANSI/ICEA S-76-474 Clause 3.6.1, the insulation meets the physical properties of Table 3-4; for crosslinked material these include 12.5 MPa minimum tensile strength and 250% minimum elongation, with at least 75% retained after 168 h at 121 °C.

Qualification

• In accordance with ANSI/ICEA S-76-474 Clause 1.5, qualification tests are made on cable specimens at the start and whenever an insulating material is changed, and the data are kept.
• In accordance with ANSI/ICEA S-76-474 Clause 6.2, a specimen bent 180 degrees round a mandrel of no more than seven times the cable diameter shows no cracks after 96 h at 100 °C.
• In accordance with ANSI/ICEA S-76-474 Clause 6.3, insulation with less than 2.0% carbon black is tested for sunlight resistance over 720 h of carbon-arc or xenon-arc exposure.

Identification

• In accordance with ANSI/ICEA S-76-474 Clause 4.2.1, when a print legend is used, it is repeated at no more than 24 in (0.61 m) and includes the conductor size, conductor metal and the 600 V rating among its required items.
