Overview 1.1 Scope This standard covers hardware for use with all-dielectric fiber optic (WRAP) cable designed to be helically wrapped around
30、a conductor or other messenger on overhead power facilities. This covers mechanical and electrical performance, test requirements, environmental considerations, and acceptance criteria for qualification of the hardware. 1.2 Purpose The purpose of this standard is to establish performance and testing
31、 specifications for hardware used on WRAP cable systems in order to standardize testing, simplify procurement specifications, and assure product quality.

All rights reserved. 4Figure 2 Illustration of span end clamp 4.1.3 Conductor mounted splice enclosure Conductor mounted splice enclosures may be used and are typically mounted close to the tower. Splicing may be carried out from a bucket or at ground le
38、vel. In the case of the splicing having been carried out at ground level, the enclosure provides storage for the cable needed to bring the enclosure to the ground (see Figure 3). Figure 3 Conductor mounted splice enclosures 4.1.4 Tower-mounted splice enclosure These enclosures may be used throughout
39、 an installation but are always needed at the ends of the installation where the WRAP cable is spliced to an underground cable. For security, the enclosure is typically mounted some way up the tower (e.g., above the anti-climbing guard). The enclosure shall be able to house the cable needed to acces
40、s the enclosure for splicing (see Figure 4). IEEE Std 1591.3-2011 IEEE Standard for Qualifying Hardware for Helically-Applied Fiber Optic Cable Systems (WRAP Cable) Copyright 2011 IEEE.

41、on In the case of a ground wire, the WRAP cable is enclosed in a pipe from the ground wire to the tower mounted splice enclosure. The pipe is attached to the tower using clamps or other securing means that do not damage the structure. The pipe material shall be able to withstand the mechanical and e
42、nvironmental stresses placed upon it (see Figure 5). Figure 5 Ground wire down leg transition 4.1.6 Phase conductor phase-to-ground transition In the case of a phase conductor, between phase and ground potential, the WRAP cable is housed in an insulator. After installation of the cable in the insula
43、tor, the insulator has no internal air surfaces or voids. In this way any leakage currents are confined to the outer surface of the insulator. The insulator is designed to limit these surface leakage currents to a safe level throughout the life of the installation. The lower end of the insulator sha
44、ll always be grounded in accordance with the utilities practice. A pipe, as described in 4.1.5, encloses the WRAP cable between the bottom of the insulator and the tower mounted splice enclosure. It should be noted that the insulator extends from the conductor to the tower structure. The entire insu
45、lator shall be treated as at phase potential, see note in Figure 6 “Caution High Voltage Zone”.

47、ut sharp edges or corners, free of cracks and shall not contain defects to the extent that the strength or suitability is affected. Holes shall be cylindrical and clean-cut. Holes in plates or terminal pads may be sub-punched and reamed, drilled, or cast in place. The periphery of the hole shall be
48、free from burrs. The finish of all bearing surfaces shall be smooth and contoured and the outer edges and corners shall be rounded as required. The hardware shall be free of metal particles, dirt, and oils. 4.2.3 Thermal design requirements The material used in the fabrication of the wrap hardware s
49、hall be capable of withstanding steady state temperatures from 40 C (40 F) to 70 C (158 F). Materials shall be capable of withstanding transient temperatures up to fault current temperatures typically 220 C (428 F) degrees max. If customers require materials to operate outside the established range those requirements shall be reviewed and agreed to with the manufacturer. Products that incorporate elastomers or non-metallic materials may be used outside the specified range as long as the design allows for adequate thermal transfer without any
