25、n National Standard C119.6-2011) This standard describes current cycle and mechanical tests used to establish performance characteristics of non-sealed, multiport distribution connectors used to join aluminum-to-aluminum, aluminum-to-copper, or copper-to-copper conductors. This revision has been reo

26、rganized to follow international formatting, and to improve the organization of information throughout the document when compared to the previous version. Substantive changes to the standard have been made in the C119.6-2011 version of the standard. A substantive change is one that directly and mate

27、rially affects performance of a product and which requires testing or retesting to meet the current edition of a standard. The substantive changes to the standard are: This version of the standard requires retesting the performance of a product if there have been substantive changes made to the prod

28、uct. This revision includes the addition of spreadsheet files in Annex D which can be used to collect current cycle test data, calculate connector stability, and generate graphs of the data and print the data to provide test results as part of the test report. The spreadsheets are provided to give t

29、est laboratories a standardized method to collect, calculate and report test data and prepare test reports. These spreadsheets were not part of earlier editions. This standard incorporates an alternate, accelerated current cycle test method, henceforth referred to as the current cycle submersion tes

30、t (CCST). The CCST method differs from the traditional current cycle test in that test conductors are rapidly cooled by immersion in chilled water at the beginning of the current-OFF cycle and requires fewer total current-ON and current-OFF cycles. The CCST method differs from the traditional curren

31、t cycle test (CCT) in that test connectors are rapidly cooled by immersion in chilled water at the beginning of the current-OFF cycle. Comparative testing has demonstrated that the CCST method will provide essentially the same performance test results as the traditional current cycle test (CCT) in f

32、ewer test cycles. The current cycle test remains the preferred test method recommended for qualification of a connector. The Subcommittee on Multiport Connectors of the Accredited Standards Committee on Connectors for Electric Utility applications, C119, in its constant review of the publication, co

33、ntinues to seek out the views of responsible users that will contribute to the development of better standards. Suggestions for improvement of this standard will be welcome. They should be sent to the National Electrical Manufacturers Association, 1300 North 17th Street, Suite 1752, Rosslyn, Virgini

41、Volts or Less for Aluminum and Copper Conductors 1 Scope and Purpose 1.1 Scope This standard covers non-sealed, multiport distribution connectors rated 600 volts or less used for making electrical connections between aluminum-to-aluminum, aluminum-to-copper, or copper-to-copper conductors for above

42、grade, electric utility applications. This standard establishes the electrical and mechanical test requirements for connectors used at normal operating temperatures not to exceed 90C (194F) and is not intended to recommend any other operating conditions. 1.2 Purpose The purpose of this standard is t

43、o give reasonable assurance to the user that connectors meeting the requirements of this standard will perform in a satisfactory manner, provided they have been properly selected for the intended application and are installed in accordance with the manufacturers recommendations. The service operatin

44、g conditions and the selection of the connector is the responsibility of the user. 2 Referenced Standards This standard is intended to be used in conjunction with the following standards.
