Where noted, one or more portions of Section 6 of this Standard provide specific instructions which may alter, clarify, icez supersede portions of the referenced standard. This applies either to a straight test piece or to one stamped out with a die, and it assumes corrugations have been removed.
Power Cables Rated 2,000 V or Less for the Distribution of Electrical Energy
The tests shall be made only on jackets having a minimum wall thickness of 25 mils 0. The conductor s in the cable shall be tested to assure continuity when grounded at one or both ends.
Failure of either of the additional specimens shall indicate failure of the sample to conform to this standard. A left-hand lay is defined as a counterclockwise twist away from the observer. The Column B thicknesses are considered adequate for electrical purposes and may be specified for single-conductor cables employing sunlight-resistant, carbon black pigmented insulation without further covering.
For a carbon-arc apparatus, five samples shall be mounted z-95-658 in the specimen drum of the carbon-arc-radiation and water-spray exposure equipment per ASTM G 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.
Test specimens shall be prepared and tested identically to the unaged test specimens. When tested in accordance with Section 6 the jacket shall meet the requirements of Table Quantities and Description of Cable Total number of feet, including test lengths, and shipping reel lengths if specific lengths are required. When there is a conflict between the test methods given in Section 6 and publications of other organizations to which reference is made, the requirements of Section 6 shall apply.
Table applies to the common overall jacket for all round multiple-conductor cables and for flat twin cables. This Standard does not require any specific frequencies for sampling for test of cable products or components. The tolerance in the nominal thickness of the tape shall be 3 mils 0. Table lists tests which are conducted according to other standards.
Except for the direct current spark test and the alternating current spark test, the voltage shall be applied between the conductor or conductors and the metallic sheath, metallic armor, or water. If the direction of lay is not reversed in a single layer cable, the conductors shall have a left-hand lay. Jute or equivalent covering may be added where the conditions of transportation require protection for the galvanizing on iceq armor wires.
For nonsheathed submarine cables, see 3. The elongation shall be ss-95-658 permanent increase in length of a marked section of the strip, originally 10 inches mm in length, and shall be determined after the specimen has fractured.
Power Cables Rated 2, V or Less for the Distribution of Electrical Energy – NEMA
The lead may be stripped from the entire length of the cable and the cable re-sheathed. Anyone using this document should rely on his or her own independent judgment or, as appropriate, seek the advice of a competent professional in determining the exercise of reasonable care in any given circumstances. In a cable in which the direction of lay is reversed: If not grounded, the hazard of shock is increased.
If all of the samples pass any test specified in this Iceq, the quantity of cable they represent shall icfa considered as meeting the requirements of this Standard with regard to that test. An insulated or uninsulated grounding conductor may be sectioned into several parts but no part shall be smaller than a No. In the case of wire and cable size 6 AWG and larger, or in the case of wire and cable smaller than size 6 AWG having an insulation thickness greater than 90 mils 2.
Compliance with cross-sectional area is not required. For other types of installations when suitably protected by metal armor or nonmetallic coverings.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. If the direction of lay is not reversed in a cable containing layers of conductors, the outer layer of conductors s-95-685 have a left-hand lay and the direction of lay of the conductors in the inner layers shall be governed by the cabling machine.
The types of coverings and conditions of installation are as follows: For cables or conditions icfa service where mechanical stresses govern, such as in submarine cables or long vertical risers, the small conductor sizes may not be strong enough. The insulation resistance shall be measured after the completed cable alternating current voltage tests s-955-658 before any direct current voltage withstand tests specified in 6.
Subscription pricing is determined by: Loosening or detachment during the adherence test of superficial, small particles of zinc formed by mechanical iea of the surface of the zinc-coated strip shall not constitute failure.
The size of the armor wires shall be as given in Tablebut the tensile safety factor shall be not less than five. Indicates that the test for the x-95-658 property does not apply to material. The outer layer of an uncoated stranded copper conductor may be tin coated to obtain free stripping of an adjacent polymeric layer. A means of measuring voltage between the electrode and ground. 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.
The direction of lay may be right-hand or left-hand. In classifying jackets and sheaths in these standards, the term “jacket” refers iceea nonmetallic coverings and “sheath” refers to continuous metallic coverings. The weight of zinc coating shall be determined before the wire is applied to the cable. The conductor s shall be grounded.
