WC 26-2008 EEMAC 201-2008 Page iii Foreword The purpose of this Standards Publication is to p

19、rovide practical information concerning the packaging of wire and cable for the North American wire and cable industry. There are, however, scores of different sizes and types of wire and cable products; and the determination of the most desirable standard packages for each, from both the manufactur

20、ers and users points of view, requires careful consideration of the many variables. The issuance or existence of these standards does not in any respect prevent or restrict any member or nonmember of NEMA or EFC from supplying customers with reels or packages not in conformance with these standards.

21、 User input has been considered throughout the development of this Standards Publication. This Standards Publication was developed by the Technical Harmonization Committee (THC) on Wire and Cable Packaging which consists of representatives from the Electrical Equipment Manufacturers Advisory Council

22、 (EEMAC), an affiliate of Electro-Federation Canada, and the National Electrical Manufacturers Association (NEMA). This standards publication will be reviewed periodically by THC and revised as necessary to keep it current with advancing technology. Comments or proposed revisions are welcomed and sh

30、c sheath itself. In all other cases, the outside diameter is the diameter outside of all the material on the cable in the state in which it is to be wound upon the reel. 2 For “flat-twin” cables (where the cable is placed upon the reel with its flat side against the drum), the minor outside diameter

31、 shall be multiplied by the appropriate factor to determine the minimum drum diameter. 3 The multiplying factors given for item E refer to the outside diameter of the duct.

32、 4.1 REEL COVERINGS Outlined below are suggestions for protective coverings on reels containing electrical cable, cord, and wire for shipment under normal conditions and proper handling. Improved methods of handling, storage, and transportation would permit lesser degrees of protective covering. Six

33、 levels of protection are defined for product type and reel size, as listed in Table 4-1.

In order to

39、help avoid weathering or damage to the cable or reel during shipment, it is suggested that cable shipped with no covering be shipped in full truck load shipments either in closed vans or in tarpaulin covered trucks.
