AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Sta

6、ndards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward

Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the Amer

29、l length. The standard barrel length varies by manufacturer and by wire size, but generally offers the ability for two or more circumferential crimps for the larger wire sizes, or one for smaller wire sizes. The major lug and inline splice manufacturers also make long barrel connectors. Again, the l

30、ength of a “long-barrel” varies by manufacturer and wire size, but offers room for more crimps than would be found on the standard barrel. In most cases, use of long-barrel lugs is not needed except in high-vibration applications. A few manufacturers may make short barrel (shorter than the standard

31、barrel) connectors for certain wire sizes. These typically only have room for a single crimp. Figure 1 - Standard Barrel Lug Figure 2 - Long Barrel Lug Some lug barrels can come with belled (flared) ends in order to ease insertion of flex cable. ATIS-0600029.2013 4 Figure 3 - Belled End Lug There do

32、es not have to be an exact fit between the inside diameter of a barrel and the outside diameter of the wire in the cable; however, they need to be close so that the crimp compression makes a conductive fit that is highly resistive to being pulled off. That said, the compression tools compress the ba

33、rrels enough that there is enough difference between inside barrel diameter and outside cable diameter that some barrels can fit multiple sizes of wire. For example, a given lug might fit both 1/0 AWG Class B (standard stranding) and 1/0 AWG Class I (flex) cables. The manufacturer will specify for w

34、hich sizes the barrel has been listed. 4.2 Inline Splices Inline splices provide a method of joining two cables end to end (also known as a butt splice) in order to minimize the space taken in a cable rack when lengthening a cable or changing size. The inline splice is essentially like two back-to-b

35、ack lug barrels (no tongues). The inline splice may connect the same size to itself (sometimes known as a two-way splice), or change from a larger size to a smaller wire size (reducing splice). The inline splice usually has inspection holes to ensure proper wire insertion, and is usually covered wit

36、h clear heat shrink (in single or multiple layers, depending on the thickness of the heat shrink) to facilitate inspection of the connector after-the-fact. Figure 4 - Reducing Splice Kit ATIS-0600029.2013 5 Figure 5 - Installed Reducing Splice 4.3 Inspection Holes Many lugs contain an inspection hol

37、e right where the transition zone starts between the barrel and the tongue. This allows an installer to determine if theyve fully inserted the wire into the barrel. Standard and short-barrel lugs (except for battery lugs) come with inspection holes. Long-barrel lugs normally do not come with an insp

38、ection hole because full wire insertion (while still important) is not as important due to the increased number of crimps. A modification to the long-barrel part number allows the user to order it with an inspection hole. Most lugs used around flooded batteries also do not contain an inspection hole

39、, in order to prevent intrusion of electrolyte mist. For straight lugs through 45 degree lugs, the inspection hole is on the top side. For greater angles (such as 60 or 90 degree lugs), the inspection hole is on the opposite side of the barrel. Figure 6 - 45 and 90 degree 2-hole Lugs Figure 7 - 2-ho

40、le Long Barrel lug w/o Inspection Hole ATIS-0600029.2013 6 Most inline splices contain two inspection holes, in order to determine proper insertion of both wires. For reducing splices, the inspection hole is right at the end of the barrel before it begins the transition zone to the other size. Figur

41、e 8 - Inline Reducing Splices with Inspection Holes 4.4 Taps There are essentially two types of taps: H-taps and C-taps. Taps can be used for transitioning from a larger cable size to one or more smaller cables, or can be used to “tap-off” a cable from a continuous main run. A tap may or may not hav

42、e a cover (clear or black), depending on whether it is used on a feed or return cable (these almost always have covers), or on a grounding system cable (these are generally not required to be covered, although they often are for aesthetic reasons). Figure 9 - Thick Walled “C“ Tap ATIS-0600029.2013 7

43、 Figure 10 - Thin Wall “C“ Tap Figure 11 - “H“ Tap 4.5 Covers however, some of them have removable two-piece dies that come from a die set that corresponds to the tool. Figure 20 - Manually Pumped Hydraulic Crimp Tool with Rotating Head Figure 21 - Detail of Rotating Head Some tools may include a ma

44、nual pump (hand or foot, or self-contained) to build hydraulic pressure. For the largest sizes of connectors and cables, electrical power is typically required to provide enough hydraulic pressure. The electrical power may be part of the tool itself (battery). There are also tools with a hydraulic p

45、ump that plugs into a wall outlet. This pump is then connected to a remote crimping head through a hydraulic hose. All of the larger tools use removable two-piece dies. 4.10 Color Codes & Die Indices Dies and connectors are color-coded to match each other. Oftentimes the name of the color is printed

46、 (and sometimes stamped) on the connector and possibly on the die so that color-blind people are not confused. Usually, the colors are common between major connector manufacturers, but there are some exceptions. Therefore, ensure that the connector manufacturers manuals, catalogs, application notes,

47、 and/or toolbox cards are consulted prior to using tools and dies from a manufacturer other than the connector manufacturer, and simply assuming that the color codes are the same. In addition, most manufacturers utilize an Index Code ATIS-0600029.2013 12 Numbering system. Each connector is assigned

48、a unique number and the associated die also contains this number. The number may be numeric, alpha, or alpha numeric. This is a secondary measure for the end user to make sure they are making a proper installation. If the connection is properly made, the die will emboss the connector with an index c

49、ode that has been engraved into the die set. 4.11 Direct-Burial Crimp Compression Connectors Buried ground wire and ground rods may be connected with mechanical connectors, exothermic welds, or irreversible copper crimp compression connectors. In larger telecommunications site applications, exothermic welds were historically used, but listed direct-burial irreversible copper crimp compression connections have been gaining in availability and popularity. Direct-burial irreversible crimp compression copper connections may use a special anti-oxidant impregnated with copper particles to
