Compliance with cross-sectional area is not required. A test specimen of the insulated conductor shall be taken after any curing and prior to the application of any coverings. For nonsheathed s-995-658 cables, see 3. Multiple grounding of shields is desirable in order to improve the reliability and safety of the circuit.

Where a conflict exists between the requirements of Section 8, or other ICEA documents, and those of Sections 1 to 7 inclusive, the requirements of specific types shall apply. The conductor shall be removed from a short length of wire by slitting the coverings. When flat steel tape, interlocked tape, or round wire armor will remain unjacketed and the cable is intended for use in below grade or potentially wet environments, cores having beddings of tapes or jute yarn shall be run through a hot asphalt compound or equivalent saturant.
Size of conductor — If conditions require other than standard stranding, a complete description should be given.
The initially applied ac test voltage shall be not greater than the rated ac voltage of the cable under test. In a cable in which the direction of lay is icfa Recommended minimum bending radii are given in Appendix F.
The maximum speed of the cable under a-95-658 may be determined in either U. The icwa of the sample shall be secured to the mandrel so that four complete turns of the sample will be exposed to the air between the securing means.
The zinc coating shall be considered as meeting this requirement iccea, when the strip is bent around the specified mandrel, the coating does not flake and none of it can be removed from the strip by rubbing with the fingers.
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. The armor shall be applied closely without appreciable space between the wires.
Their use is recommended also for resonant grounded systems.
The average of the results of these tests is to be reported for the lot. Insulation thicknesses are designated in terms of cable insulation levels see 3. Supplementary outer coverings for corrosion or other protection of the armor shall be applied when required. The specimen shall not be immersed in water earlier than 48 hours after any curing.
Power Cables Rated 2, V or Less for the Distribution of Electrical Energy – NEMA
The weight of zinc coating shall be determined before the wire is applied to the cable. Testing of icew material may be substituted for testing on finished cable. The height H of the segment is the thickness along the center-line of the specimen. Number of phases and conductors. Wet or dry location. Some migration is known to occur.
When intended for installation in permanently dry indoor above-grade locations, saturant compounds need not be applied to the core beddings. If measurements are made at a temperature other than 25? The bands shall be applied sufficiently tight to prevent their movement along the cable as kcea result of handling the cable during installation. To reduce the hazard of shock it is recommended that the shield be grounded at cable terminations and at splices and taps.
The alloy shall be determined by the manufacturer unless otherwise agreed upon between the manufacturer and the user. Standards Subsctiption may be the perfect solution. When the direction of lay is reversed, the beginning and 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. Direct burial in trenches and subjected to unusual longitudinal stress.
