8、Type test item of characteristic test adapt aluminum conductor steel-reinforced used in 500 kV line
1）Wriggle variation performance parameter
Sample number :4(for example LGJ-720/50)
Test condition sample length:
Length of two end sample:14m
Treatment of two end sample: epoxy resin pouring
Testing valid length of the simultaneity elongation instrument
Rest temperature:20 ±1℃
Test precision:
Stress: ±1%
Strain: ±0.01mm/5000m
Sample tension:25.59kN(15%RTS)
42.66kN(25%RTS)
59.71kN(35%RTS)
sample record time: when tension loading reach a value, homologous value of elongation and temperature are recorded at the increasing time of 1、2、3、4、5、6、7、10、15、30、60 minutes;following three day, the value are recorded every one hour; form day to the five day, the value are record every two hour; form the six fourteen day, the value are recorded every four hour; from the fifteen day, the value are recorded every six hour, the testing time is 1000 hour.
Test result: The wriggle variation equation at the 15%RTS、25%RTS、35%RTS、tension loading can deduce the wriggle variation value as following: 280、541and 794mm/km.
2）Vibratory fatigue test
Vibratory parameter: Vibratory angle: 25~300, tension is the percent 25 of breaking;
Vibratory time: 3 × 107
Test result: single aluminum wire non-breaking.
