The maximum length of lay shall be 60 times the diameter of the largest insulated conductor. In a cable in which the direction of icew is reversed: The cross-sectional area of a stranded conductor shall be calculated from its maximum diameter and shall include the areas between the strands.

Failure of either of the additional specimens shall indicate failure of the sample to s-955-658 to this standard. The conductor shall be removed from a short length of wire by slitting the coverings.

The conductor s in the cable shall be tested to assure continuity when grounded at one or both ends. The sample shall then be inserted vertically in a hole in a flat rigid plate which is at least 10 mils 0.

Power Cables Rated 2,000 V or Less for the Distribution of Electrical Energy

The exposure time shall be hours. Wire band servings in accordance with 4. For insulation subjected to a second curing, samples of the insulated conductor may be taken either before or after the second curing. For this calculation, the area of the conductor also includes the crosssectional area of any separator between the insulation and the conductor.

NEMA and ICEA disclaims liability for personal injury, property, or other damages of any nature whatsoever, s9-5-658 special, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, application, or reliance on this document. The test voltages shall be based on the rated voltage of the cable and the size of the conductor and not on the apparent thickness of the insulation.

The thickness of the insulation shall be not less than that given in Tables through for the s-95-6588 insulation types and voltage ratings. The duration of the dc voltage test shall be 5 minutes.

Drain wires s-5-658 be positioned adjacent to the metal tape so as to maintain effective grounding contact and shall be considered an integral part of the shield. The thicknesses of insulation given in Tables,andshall apply to single-conductor cables and to the individual conductors of multiple-conductor cables, except nonsheathed submarine cables. Quantities and Description of Cable Total number of feet, including test lengths, and shipping reel lengths if specific lengths are required.


For s-995-658 conductor cables with individual conductors having a metallic sheath or armor over the cable assembly, the test voltage shall be applied between each insulated conductor and all other conductors and ground.

If necessary, the process shall be repeated with another length of combined materials, except that the other layer shall be buffed off. If the required tensile safety factor is not maintained, the next larger size ieca given in the table should be used.

The ac voltages are rms values.

Interlocked metal tape armor or continuously corrugated armor without an outer covering but with either a bedding or a jacket under the armor is suitable for cables for indoor use and for outdoor aerial service. For a carbon-arc apparatus, five samples shall be mounted vertically in the specimen drum of the carbon-arc-radiation and water-spray exposure equipment per ASTM G The pitch ratio is taken as the quotient resulting from dividing the length of lay of the armor wires by the pitch diameter of the armor wires.

Where unusual service conditions exist, it may be desirable to modify the pitch ratio. If planing is employed, strips of the combined materials shall be cut from the conductor so that acceptable specimens can be prepared from these strips in such a manner that material from only one layer is present in the region between the gauge marks.

Cables in this category may be applied in situations where the clearing time requirements of the icez level category cannot be met, and yet there is adequate assurance that the faulted section will be de-energized in a time not exceeding 1 hour.

The corrugations shall be at right angles to the axis of the cable and shall coincide exactly at the overlap. The initially applied ac test voltage shall be not greater than the rated ac voltage of the cable under test. The intervals need not be uniform. In lieu of calculation, the value may be obtained from a table giving the areas of a unit circle for the ratio of the height of the segment to the diameter of the circle.


Any certification or other statement of compliance with any health or safety-related information in this document shall not be attributable to NEMA and ICEA and is solely the responsibility of the certifier or maker of the statement.

Supplementary outer coverings for corrosion or other protection shall be applied when required.

Wet or dry location. If the direction of lay is not reversed in a s-9-658 containing layers of conductors, the outer layer of conductors shall have a left-hand lay and the direction of lay of the conductors in the inner layers shall be governed by the cabling machine. We have no amendments or corrections for this standard. The metal shield shall be applied in such a manner that electrical continuity or contiguity will not be distorted or disrupted during normal installation bending see Appendix F.

For either one or two servings, the outer serving shall be further coated with some suitable material, which will prevent sticking of adjacent turns of the cable when wound on a reel. Insulation thicknesses are adequate for both percent and percent insulation levels. A coating of compatible material on the binding strip or wire is acceptable. Samples of thermoplastic-insulated conductors for the unaged and aged physical tests shall be taken prior to the application of all coverings except those applied in the same process as the application of the insulation.

Diameter measurements, when specified, should be made with the use of a diameter tape accurate to 0. Where a conflict exists ices the requirements of Section 8, or other ICEA documents, and those of Sections 1 to 7 inclusive, the requirements of specific types shall apply.

In classifying jackets and sheaths in these standards, the term “jacket” refers to icwa coverings and “sheath” refers to continuous metallic coverings. Insulation resistance measured at other temperatures o shall be converted to insulation resistance at
