1、 AMERICAN NATIONAL STANDARD FOR TELECOMMUNICATIONS ATIS-0600028.2016 DC Power Wire and Cable for Telecommunications Power Systems for XHHW and DLO/Halogenated RHH-RHW Cable Types As a leading technology and solutions development organization, the Alliance for Telecommunications Industry Solutions (A
2、TIS) brings together the top global ICT companies to advance the industrys most pressing business priorities. ATIS nearly 200 member companies are currently working to address the All-IP transition, 5G, network functions virtualization, big data analytics, cloud services, device solutions, emergency
3、 services, M2M, cyber security, network evolution, quality of service, billing support, operations, and much more. These priorities follow a fast-track development lifecycle from design and innovation through standards, specifications, requirements, business use cases, software toolkits, open source
4、 solutions, and interoperability testing. ATIS is accredited by the American National Standards Institute (ANSI). The organization is the North American Organizational Partner for the 3rd Generation Partnership Project (3GPP), a founding Partner of the oneM2M global initiative, a member of and major
5、 U.S. contributor to the International Telecommunication Union (ITU), as well as a member of the Inter-American Telecommunication Commission (CITEL). For more information, visit www.atis.org. AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the requir
6、ements 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 Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreeme
7、nt 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 towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any resp
8、ect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpr
9、etation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose
10、name appears on the title page of this standard. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers o

36、dual conductor strands shall be bare or tinned (lead free), soft or annealed copper wire meeting the electrical and mechanical requirements of ASTM B3 or ASTM B 33. 5.2 Conductor Stranding Type 5 cables shall be constructed of conductors having concentric (reverse concentric, unilay, or combination)
37、 lay members per ASTM B8, Class B. Type 6 cables shall be constructed of concentric (reverse concentric, unilay, or combination) rope-lay stranded copper conductors having bunch stranded members per ASTM B172, Class I. ATIS-0600028.2016 8 5.3 Conductor Size & Dimensions The conductor diameters shall
38、 be within -2%+5% of the nominal value and shall not be less than the minimum values in Tables 5.1 and 5.2. The DC resistance shall not exceed the maximum value for tinned copper in Tables 5.1 and 5.2. The bare wire conductor diameter shall be determined by: 1. Removing approximately one inch of ins
39、ulation from a cable sample at least 6 inches from the end so that there is at least 6 inches of cable insulation on each side of the exposed conductor where the insulation has been removed. 2. Take four individual diameter measurements (with a calibrated digital machinists micrometer-caliper) made
40、45 degrees apart around the exposed bare wire conductor of the cable sample. 3. Average the four measurements to determine the bare wire conductor diameter. Cross-sectional Area shall be determined using the weight method defined in UL 1581, section 210. The number of strands and diameter of each st
41、rand are provided for reference. The more important parameters are: finished stranded conductor diameter, cross sectional area, and electrical resistance.
