The zinc coating shall be considered as meeting this requirement if, 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.
The dimensions of the specimen to be s-95-6558 shall be determined before aging.
Failure of any sample shall not preclude resampling and retesting the length of cable from which the original sample was taken. Number of loaded cables in duct bank or conduit. For other types of installations when suitably protected by metal armor or nonmetallic coverings.
The insulating material shall meet the dimensional, electrical and physical requirements specified in Section 3.
Insulated Cable Engineers Association, Inc. The requirements for the tensile strength of flat steel tape and for the zinc coating shall be in accordance with 4. Compliance with cross-sectional area is idea required. The messenger shall extend a minimum of 5 feet 1. When tested in accordance with Section 6 the jacket shall meet the requirements of Table In some instances it may be possible to prepare specimens of one layer by planing but necessary to prepare specimens of the other layer by buffing.
Physical tests on both the aged and unaged kcea shall be made at approximately the same time. Specimens may be immersed in a common bath.
For zinc coated s-956-58 tape the specified nominal thickness and tolerance shall apply to the stripped bare metal.
NEMA and ICEA disclaims and makes no guaranty or warranty, expressed or implied, as to the accuracy or completeness of any information published herein, and disclaims and makes no warranty that the information in this document will fulfill any of your particular purposes or needs.
The bands shall be applied sufficiently tight to prevent their movement along the cable as a result of handling the cable during installation. 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 Ica.
Power Cables Rated 2,000 V or Less for the Distribution of Electrical Energy
The thickness of the insulation shall be not less than that given in Tables through for the various insulation types and voltage ratings. 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. A jute or equivalent serving as specified in 4.
The test specimens shall be molded from material taken from the completed cable. Metal tapes shall be a nonmagnetic material such as copper, copper alloy, or aluminum. For the xenon-arc apparatus, five samples shall be mounted, top and bottom, on a rack of the xenon-arc-radiation and water spray exposure equipment per ASTM G The methods to be used are: The lead may be stripped from the entire length of the cable and the cable re-sheathed.
The width of the corrugated tape shield shall be such that after corrugation the edges shall overlap by not less than 0. C shall be calculated using the following formula: A coating of compatible material on the s95-658 strip or wire is acceptable.
Rated circuit voltage, phase to phase. The average of the results of these tests is to be reported for the lot. Otherwise, the steel strip except stainless shall s-995-658 zinc-coated. Ciea to materials, constructions, and testing of volts and less thermoplastic, crosslinked polyethylene, and crosslinked rubber insulated wires and cables which are used for the transmission and distribution of electrical energy for normal conditions of installation and service, either indoors, outdoors, aerial, underground, or submarine.
Power Cables Rated 2, V or Less for the Distribution of Electrical Energy – NEMA
In classifying crosslinked insulations and jackets in these standards, the term “rubber” when used alone without further description shall mean synthetic rubber. Increase in capacitance, max. Specimens shall not be heated, immersed in water, nor subjected to any mechanical or chemical treatment not specifically described in this Standard. There are situations where the above thicknesses may require an increase, especially on the smaller sizes of cable, such as when several cables are to be pulled together in one duct, or the sections to be pulled are extra long, or the handling during installation is severe or awkward, as in some transformer vaults.
Column A thicknesses shall apply to single-conductor power cables and multiple conductors without an overall jacket for general application which employ a sunlightresistant, carbon-black pigmented Insulation without further covering.
Determination of unaged properties: Already Subscribed to this document.
Each length of insulated conductor containing repairs or joints shall meet the electrical requirements of Tables and as applicable. When tested in accordance with Section 6, the jacket shall meet the applicable requirements of Table 4.
This test shall be made on a sample of wire having an icra length of 6 inches mm between jaws of a standard torsion machine or equivalent with one head of the machine movable horizontally.
Loosening or detachment during the adherence test of superficial, small particles of zinc formed by mechanical polishing of the surface of zinc-coated wire shall not constitute failure.
The initially applied ac test voltage shall be not greater than the rated ac voltage of the cable under test. Material Supplier’s certification shall be acceptable in lieu of the procedures above. An insulation resistance stability qualification test shall be performed icsa samples of insulated single conductor cables to determine that the insulation is suitable for use in ac circuits s-95-58 wet locations. Table applies to the common overall jacket for all s-9-5658 multiple-conductor cables and for flat twin cables.
Drain wires shall be positioned adjacent to the metal tape so as to maintain effective grounding contact and shall be considered an integral part of the shield. 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 Stranded includes compressed and compact conductors. For cores having a diameter smaller than 0. The direction of lay of the armor wires shall be so chosen to minimize birdcaging of the cable core being armored.
