ANSI C119.5-2009 AMERICAN NATIONAL STANDARD Approval of an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. C

13、onsensus 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 agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views an

14、d objections be considered, and that a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, o

15、r 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 interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an in

27、tests used to establish performance characteristics of insulation piercing connectors used to join insulated and non-insulated overhead conductors. The qualification tests may be made before supplying, on a commercial basis, connectors covered by this standard, in order to demonstrate satisfactory p

28、erformance characteristics to meet the intended application. Qualification tests, once successfully completed, need not be repeated, unless changes are made in the materials, design, or manufacturing process that might change the connectors performance characteristics.

Breakage of any conductor strand is considered un

35、acceptable results. Connectors of the type that do not have separate gripping means for the different metals of composite conductors or that use nonferrous means on ferrous conductors or cores shall first be tested in accordance with 6.2.1.1 without slippage or breakage. 4.2.1.2 Class 2, Partial Ten

36、sion The tensile strength shall be equal to or greater than 40% of the rated conductor strength of the weaker of the conductors being joined. 4.2.1.3 Class 3, Minimum Tension The tensile strength shall be not less than 5% of the rated conductor strength of the weaker of the conductors being joined b

37、ut not less than the values in Tables 1 and 2. 4.2.2 One (1) Minute Load Test The pull-out force as specified in Table 3 shall be applied without separation of conductor from the test sample when subjected to the One (1) Minute Load Test of 6.2.2. 4.2.3 Conductor Damage The test sample shall be subj

38、ected to the Conductor Damage Test of 6.2.3 without failure of the run conductor. 4.2.4 Bolt Tightening A bolted connector shall withstand 120% of the manufacturers recommended tightening torque without cracking, rupture, or permanent distortion of any connector component that impairs its proper fun

39、ctioning when subjected to Bolt Tightening Test of 6.2.4. In the absence of manufacturers recommended torque, use 120% of values shown in Table 4. 4.2.5 Shear Head Function (Shear Head Bolt Type IPC Only) Bolt head shearing shall occur within the torque range specified by connector manufacturer when

40、 subjected to Shear Head Function Test of 6.2.5. This test applies to shear head bolt type connectors only. 4.2.6 Connector Mounting Test at Low Temperature The test sample shall exhibit electrical continuity when subjected to the Connector Mounting Test of 6.2.6. 3 ANSI C119.5-2009 4.3 Electrical T

41、ests 4.3.1 Dielectric Withstand Test An insulated wire connector shall withstand the applied voltage, without breakdown, when subjected to the dielectric-withstand test as specified in 6.3.1. The insulation of an insulated connector shall not crack or break when the connector is assembled as intende

42、d on the conductor. The oven conditioning described in 6.3.1.1 shall not adversely affect the insulating properties of the conductor insulation or the connector insulation. NOTEDiscoloration of the connector insulation is allowed. 4.3.2 Current Cycling Test 4.3.2.1 Resistance The resistance of the c

43、onnection tested in accordance with 6.3.2 shall be stable. Stability is achieved when any resistance measurement, including allowance for measurement error, does not vary by more than plus or minus five percent (5%) from the average of all the measurements at specified intervals during the course of

44、 the test. The resistance of the connection tested by the Current Cycling Test method in accordance with 6.3.2 shall be stable between the 100th cycle and the completion of the number of current cycles required in 6.3.2.1. 4.3.2.2 Temperature The temperature of the connector when tested in accordanc

45、e with clause 6.3.2 shall not exceed the temperature of the control conductor. The temperature difference between the control conductor and the connector shall be stable as determined as follows. The stability factor “Si” shall not exceed 10 for each of the specified connector temperature measuremen

46、ts recorded at the intervals specified in Table 15. The stability factor, Si, for each of the specified recorded temperature measurements shall be determined by applying the following equations: Si= di- D D =d1+d2+.+dn)/n in which: D is the average temperature difference, n is the specified number o

47、f temperature measurements The variable “i” is a number from 1 to n and signifies one of the individual temperature measurements, and diis a temperature difference for an individual temperature measurement. di = (Tcc- Tc)i i = 1, 2, ,n Tc is connector temperature in C Tcc is the control conductor te

48、mperature in C n = 11 NOTEFor each connector, the value for diis determined by subtracting the connector temperature from the control conductor temperature for each of the eleven data points. Next, the average temperature difference (D) is then calculated and subtracted from each of the individual d

49、ata points to attain eleven Sivalues. Each of these eleven Sivalues is to be within the range of 10. See the example in Annex B, Table B1. 4 ANSI C119.5-2009 4.3.3 Dielectric Withstand/Leakage Current and Water Penetration Tests (Class W) 4.3.3.1 Dielectric Withstand/Leakage Current Test The connector shall not experience breakdown or flashover when subjected to the dielectric test specified in 6.3.3.1. The leakage current shall not exceed 1 mA. 4.3.3.2 Water Penetration Test After immersion, as stipulated by 6.3.3.2, there shall be no evidence of water
