Single- or multiconductor – V – 90ºC – ICEA S Halogen-free (LSZH- HFFR). MH. Applications. Recommended for use in highly populated enclosed. ANSI/NEMA WC ICEA S Power Cables Rated Volts or Less for the Distribution of Electrical Energy Published by National. ANSINEMAWC70ICEANonshielded Power Cables Rated Volts or Less for the Distribution of Electrical Energy-Applies to materials, constructions.
The duration of the dc voltage iccea shall be 5 minutes. After the specified voltage is applied, the entire length of cable shall be passed through the electrode in a manner and at a speed such that every section of cable surface will have maintained electrode contact for not less than 18 positive and negative voltage crests. The messenger shall be laid parallel to the axis of a single conductor or x-95-658 assembled conductors.
Table applies to the common overall jacket s-95-6658 all round multiple-conductor cables and for flat twin cables. 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.
If, during installation, the shaft cable is suspended from one end, galvanized round steel wire armor shall be used. These cables may be used in applications where installation and service conditions are such that the additional thickness for mechanical protection is not considered necessary for satisfactory operation. Resistance will be determined in accordance with 2.
When intended for installation in permanently dry indoor above-grade locations, saturant compounds need not be applied to the core beddings. Joints in the tape shall be made electrically continuous by welding, soldering, or brazing. The jacket shall meet the requirements stated therein and those given in Table and The specimen shall be of a length sufficient to immerse at least 10 feet 3.
Tests on samples shall be made on samples selected at random. Division III See 4.
The length of the serving band and the spacing of the band throughout the length of the cable shall be in accordance with Table Number of loaded cables in duct bank or conduit. Normal operating voltage between phases or, in direct current, between conductors. 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.
For cables or conditions of service where mechanical stresses govern, such as in submarine cables or long vertical iicea, the small conductor sizes may not be strong enough. All tests shall be made s-956-58 to the application of the strip to the cable. 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 Drain wires shall be positioned adjacent to the metal tape so as d-95-658 maintain effective grounding contact and shall be considered an integral part of the shield.

This provides the tensile and elongation ratios for the jacket. Information and other standards on the topic covered by this publication may be available from other sources, which the user may wish to consult for additional views or information not covered by this publication. The frequency of the test voltage shall be nominally between 49 and 61 hertz and shall have a wave shape approximating a sine wave as closely as possible.
Method of bonding and grounding of sheaths. Cable shall not propagate flame to the top of the test specimens. The insulation shall be one of the classes given in Table See Section 6 for method of measuring metal tape thickness. Five die-cut specimens shall be prepared and tested for tensile and elongation from 1 unaged section of the cable jacket and 2 the conditioned samples, one specimen from each sample. For nominal widths greater than 1.

Nominal mils 30 45 60 80 95 mm 0. 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.
Immersion in water is not required. Approximate diameters of individual wires in stranded conductors. Each test sample shall be taken from an accessible end of a coil or reel. Determination of unaged properties: The armor shall be applied closely without appreciable space between the wires.
