Members of the committees serve voluntarilyand without compensation. They are not necessarily members of the Institute. The standards devel-oped w
5、ithin IEEE represent a consensus of the broad expertise on the subject within the Institute aswell as those activities outside of IEEE that have expressed an interest in participating in the devel-opment of the standard.Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard d
6、oes not implythat there are no other ways to produce, test, measure, purchase, market, or provide other goods andservices related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at thetime a standard is approved and issued is subject to change brought about through developmen
7、ts inthe state of the art and comments received from users of the standard. Every IEEE Standard is sub-jected to review at least every five years for revision or reaffirmation. When a document is morethan five years old and has not been reaffirmed, it is reasonable to conclude that its contents,alth
8、ough still of some value, do not wholly reflect the present state of the art. Users are cautioned tocheck to determine that they have the latest edition of any IEEE Standard.Comments for revision of IEEE Standards are welcome from any interested party, regardless ofmembership affiliation with IEEE.
9、Suggestions for changes in documents should be in the form of aproposed change of text, together with appropriate supporting comments.Interpretations: Occasionally questions may arise regarding the meaning of portions of standards asthey relate to specific applications. When the need for interpretat
10、ions is brought to the attention ofIEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards rep-resent a consensus of all concerned interests, it is important to ensure that any interpretation hasalso received the concurrence of a balance of interests. For this
11、 reason, IEEE and the members of itssocieties and Standards Coordinating Committees are not able to provide an instant response tointerpretation requests except in those cases where the matter has previously received formalconsideration.

24、for shoulder live line extension links used inoverhead transmission and distribution hardware.1.2 ApplicationShoulder live line extension links conforming to the requirements of this standard shall in all respects meetthe basic dimensional and performance requirements herein stated. Shoulder live li
25、ne extension links arenormally used at an attachment location for tools when changing out a string of suspension insulators. Thiswork may be performed while the line is energized or de-energized.2. MaterialThe shoulder live line extension links may be made of any material acceptable to the purchaser
26、, subject onlyto the limitations imposed by specified dimensions and minimum strength requirements.3. DimensionsThe dimensions in Figure 1 apply to the insulator end of the shoulder live line extension link. This end maybe in the shape of a standard ball, socket, eye, clevis, or oval eye fitting, de
27、pending upon application. Thedimensional requirements of Figure 1 shall be maintained. IEEEStd C135.63-1998 IEEE STANDARD FOR SHOULDER LIVE LINE EXTENSION 2Copyright 1998 IEEE.

30、 adequacy of the design of the shoulder live line extensionlink when incorporated with any standard ball, socket, eye, clevis, or oval eye type fitting. These tests are notmeant to be routine tests or to replace routine tests.4.1 Test procedureFive product samples of any one combination of shoulder
31、and insulator end fittings that conform to this stan-dard shall be subjected to the following test. Each test sample shall be held by the appropriate type of testfixture shown in Figure 2 and tested in the manner shown in Figure 3. The load shall be started at zero andsmoothly brought up in a practi
32、cally stepless variation to 75% of the full rated strength of the shoulder liveline extension link i.e., 101 kN (22 500 lbf) for a 135 kN (30 000 lbf) extension link. Alternately, the loadmay be increased rapidly to approximately 50% of rated strength. The load from 50% to 75% of ratedstrength shall
33、 be applied at a rate of 25% of the rated strength per minute.The shoulder live line extension link shall be held at 75% of rated strength for 3 min. The load shall then bereleased and the parts inspected. None of the five shoulder live line extension links shall fracture or shear.Local brinelling a
34、round the shoulder of the shoulder live line extension link from the test fixture is acceptable.The five samples shall then be pulled to failure. The load shall be started at zero and brought up smoothly ina practically stepless manner. The load may be increased rapidly to approximately 75% of rated
35、 strength ofhardware. The load shall then be applied smoothly at a rate of 25% of rated strength per minute until point offailure.Failure of any sample at less than 95% of rated strength requires retest. Failure of more than one samplebetween 95% and 100% requires retest. Retests shall be on 10 prod
36、uct samples with the same criteria as above. If the retest fails, the design fails.4.2 Test reportsAll tests shall be permanently recorded for a period of 10 years. Each test write-up shall contain thefollowing: Date of test; Location of test; Catalog part number; Hardware rating; Description of tes
37、t setup, including serial numbers of test equipment; Date of latest calibration of test equipment; Condition of item after 75% loading (e.g., “no permanent deformation noted,” “some brinelling,”etc.); Test results and any pertinent notes including description of failure, if any; Statement that the h
38、ardware does or does not meet the requirements of IEEE Std C135.63-1998; and Signature of inspector performing or witnessing the test.IEEEStd C135.63-1998 IEEE STANDARD FOR SHOULDER LIVE LINE EXTENSION 4Copyright 1998 IEEE.
