2、11 IEEE. All rights reserved. Introduction This introduction is not part of IEEE Std 1185-2010, IEEE Recommended Practice for Cable Installation in Generating Stations and Industrial Facilities. Construction of generating stations and industrial facilities involve the installation of a large number
3、of cables in various raceway types such as conduits, trays, duct banks, trenches, wire ways, direct burial, etc. The majority of these cables are unshielded, and except in duct banks or direct burial, where water may be present, there is usually no uniform continuous ground plane on the outside of t
4、he cable to allow effective post-installation voltage testing of the cable. Without a continuous ground plane, effective cable post-installation testing, as well as the ability to detect cable damage prior to placing the cable in service, is limited. Therefore, greater emphasis needs to be placed on
5、 wire and cable installation methods and practices to assure proper cable installation and long life. Previously, cable storage/handling information and installation recommendations were provided in IEEE Std 422-1986 B24 and IEEE Std 690-1984.aSince IEEE Std 422-1986 has not been updated since its o
6、riginal issue and is now withdrawn, and since IEEE Std 690-2004 B30 has removed the cable installation information, which were in the Appendices to IEEE Std 690-1984, this revision to IEEE Std 1185-1994 has been developed to capture and update information needed to properly install wire and cable an
7、d therefore improve safety and help assure reliable and long lasting service life. It should be noted that other documents such as cable manufacturers cable installation manuals, IEEE/IEC/AEIC standards, National Electrical Code(NEC) (NFPA 70, 2007 Edition), etc., are available that provide cable sy
8、stem design and installation information.bIt is not the intent of this recommended practice to replace or supersede the other information but to compliment it and as needed provide more detail, or alternate methods and techniques for proper cable installation. It is also not the intent of this docum
9、ent to override the installation requirements outlined in governing documents such as NEC, cable manufacturers installation manuals or permitting documents, etc. Even though utilities in certain situations may be exempt from requirements of NEC, the utility is not exempt from following good cable in
10、stallation practices in an effort to maximize cable life and minimize in-service cable failures. Improved installation methods are also expected to increase confidence in the ability of the installed cable to function in the accident environments for nuclear power generating stations, and increase c
11、onfidence in cables that improve safety and reliable operation of industrial facilities and cogeneration/fossil plants. Monitoring pulling tensions is an effective approach to ensuring that the cable pulling limits, such as minimum bend radius, sidewall bearing pressure (SWBP), and conductor strengt
12、h, are not exceeded. Since most cable pulls are manual pulls and the setup time to monitor pulling tension is prohibitive, pulling tensions are typically only monitored when performing long, high tension pulls requiring the use of motorized pulling equipment. When a manual cable pull into conduit is
13、 made, the dynamometer reading has to be adjusted after measuring various angles. Due to the complexity of this process, manual cable pulls are seldom monitored. This document introduces the use of conduit-cable pulling charts and other methods as alternatives to direct monitoring of the pulling ten
14、sions. This document also provides cable lubrication methods, conduit-cable pulling charts, pull rope selection criteria, pulling attachment methods, and alternative methods to traditional cable pull tension monitoring, etc. Cable pullbys are a common practice in the utility industry and often not t
15、horoughly addressed in either cable manufacturer literature or existing industry standards. Some utilities have reported damage to the existing cables in the conduits when executing pullbys (i.e., pulling cables into conduits that already contain cables). Monitoring the pulling tensions may help but
16、 may not prevent cable damage due to pullbys, since the damage can occur from the pull rope or pulled by cable as the pull rope or cable passes aThe numbers in brackets correspond to those of the bibliography in Annex F. bInformation on references can be found in Clause 2. v Copyright 2011 IEEE.

Instead of prohibiting the practice of cable pullbys, the cable installation process should be more carefully controlled by evaluating the pullby conditions prior to starting and placing restrictions on the process to avoid cable damage. However, it should be
18、recognized that this is a risky procedure and damaged cables or questionable conditions can result from cable pullby practices. AEIC CG5-05 B3 and IEEE P971 B18 compliment this document for long power cable pulls through duct bank systems and should be considered as additional reference sources. Cab
19、le installation information can also be found in IEEE Std 576-2000 B28 and may also be consulted as an additional reference source. Due to the requirement (IEEE Policy 9.18) to show metric units as the primary measurement unit, the English units are shown for convenience in parentheses after the met
20、ric units. The user of this document is cautioned to pay close attention to the units of the equations (metric versus English) and select units accordingly. Conformance to this standard can be achieved using either metric or English units provided the user is consistent when selecting and applying t
21、he units. The user is strongly cautioned not to mix units as mixing units can and will result in installation issues. The user is encouraged to select units that are most familiar to the installers so as to minimize the potential for creating installation problems that could go undetected until wire
22、 and cable failures occur, which is often years after installation. An attempt was made to keep the significant figures of the metric and English units comparable. However, due the application of rounding principles, the mathematical conversion from English numbers to metric numbers may not be exact
