This standard specifies the range of use, technical requirements, sampling, testing, acceptance and packaging of the porcelain or composite rod-shaped supporting insulator for the pantograph, busbar (conducting rod) on the AC25kV side of the roof of electric locomotives and electric vehicle groups.
This standard applies to the electric locomotive, electric vehicle group AC25kV side of the pantograph, busbar (conducting rod) porcelain or composite rod supporting insulator.
Other forms of detection may be performed roof insulator <br> <br> mechanical properties refer to this standard:
In the insulator mechanical performance test, the locomotive pantograph supporting insulator should be able to withstand the bending failure load not less than 8kN; the locomotive bus supporting insulator should be able to withstand the bending failure load not less than 4kN.
Insulator bending load device selection:
Insulator bending failure load performance test selection ZCW-S/W insulator compression resistance bending test bench. Offset test under load: One end of the test specimen is fixed, and the other end is bent evenly perpendicularly to the axial direction of the insulator to break the load, and the offset value of the insulator at 200.6, 50% and 70% of the specified load is recorded. The offset should be measured on the top surface of the insulator.
If the supply and demand sides do not specify the temperature conditions of the test in the contract, the test is conducted at room temperature. From: Jinan Zhongchuang Industrial Test System Co., Ltd. Technical Department
