Power Cables Rated 2, V or Less for the Distribution of Electrical Energy – NEMA
icfa Single-conductor cables in sizes 9 AWG and smaller shall not be used for direct earth burial. The maximum length of lay shall be 60 times the diameter of the largest insulated conductor. A volume resistivity of For cables having a metallic sheath, shield or armor over the individual conductor sthe test voltage shall be applied between the insulated conductor s and ground.
The specimen shall not be immersed in water earlier than 48 hours after s-95-6558 curing. Division III See 4. You may delete a document from your Alert Profile at any time.
Indicates that the test for the applicable property does not apply to material. All tests shall be made prior to ica of the wire to the cable. The sample shall then be inserted vertically in a hole in a flat rigid plate which is at icew 10 mils 0. If buffing is -s95-658, the buffing apparatus for this operation shall be equipped with a cylindrical table arranged so that it can be advanced very gradually.
While these cables are applicable to the great majority of cable installations which are on grounded systems, they may be used also on other systems for which the application of cables is acceptable provided the above clearing requirements are met in completely de-energizing the faulted section. Number of phases and conductors.
Approximate diameters of individual wires in stranded conductors. The outer layer of an uncoated stranded copper conductor may be tin coated to obtain free stripping of an adjacent polymeric layer. The bands shall be applied sufficiently tight to prevent their movement along the cable as a result of handling the cable during installation. The length of lay of the s-95-6558 in a multi-conductor cable ivea be determined by measuring, parallel to the longitudinal axis of the cable, the pitch of each successive convolution of one conductor.
The jacket material and thickness shall be as listed in Section 4. The conductor shall be removed from a short length of wire by slitting the coverings. Alternate Stability Factor, Difference days, max. The cross-sectional area of icwa stranded conductor shall be calculated from its maximum diameter and shall include the areas between the strands.
Table lists tests which are conducted according to other standards. Supplementary outer coverings for corrosion or other protection shall be applied when required. Nominal mils 30 45 60 80 95 mm 0. This standard is also available s-955-658 these packages:. A left-hand lay is defined as a counterclockwise twist away from the observer.
The weight of zinc coating ifea be determined before application of the strip to the cable. The test s-9-658 shall be suspended vertically in such a manner that they are not in contact with each other or the sides of the chamber.
The weight of zinc coating shall be determined before the wire is applied to the cable. A test specimen of the insulated conductor shall be taken after any curing and prior to the iicea of any coverings.
This Standard does not require any specific frequencies for sampling for test of cable products or components. Insulation thicknesses are designated in terms of cable insulation levels see 3. Multiply the phase to phase system voltage by 1. When the full cross-section is used, the specimen shall not be cut longitudinally.
Diameter measurements, when specified, should be made with the use of a diameter tape accurate to 0. See Section 6 4. An insulated or uninsulated grounding conductor may be sectioned into several parts but no part shall be smaller than a No.
Power Cables Rated 2,000 V or Less for the Distribution of Electrical Energy
When a interlocked metal tape armor or a continuously corrugated armor is to be applied, only a suitable tape bedding is required. For nonsheathed submarine cables, see 3. When a core with an unjacketed sheath is to have a flat steel w-95-658 or round wire armor, it shall be protected with a suitable bedding having a nominal thickness in accordance with Table Rated circuit voltage, phase to phase.
This lay shall be used such that the armor will be applied closely without appreciable space between wires. For cables with individual conductor diameters of more than 0. When the direction of lay is reversed, the beginning s-95-68 end of area reversal shall be defined on either side by the last convolution that does not exceed the maximum lay requirement on either side of the reversed area.
An insulation resistance stability qualification test ixea be performed on samples of insulated single conductor cables to determine that the insulation is suitable for use in ac circuits in wet locations. In lieu of testing finished cable jackets, a certification by the manufacturer of the polyethylene compound that this requirement has been complied with shall suffice.
When the applied flat steel tape, interlocked tape, or round wire armor will remain unjacketed and the cable is intended for installation in below-grade or potentially wet environments, the metallic sheath and jute bedding layers applied over the sheath or core jacket shall be run through a hot asphalt or tar compound, or equivalent saturant.
Test specimens shall be prepared and tested identically to the unaged test specimens. Flat metal tape armor.
