5000h Insulator Testing Machine
   
  
  
  Remark :
  The IEC 62730 standard is an international standard for multi stress aging testing of insulators used in photovoltaic (PV) systems, primarily evaluating the long-term durability of insulation materials in complex outdoor environments. The IEC 62730 Insulator Multi Stress Testing Machine is a testing device specifically designed to simulate the superposition of various environmental stresses and accelerate the aging of insulators.
   
   	 		 			|  			 Product name:  			 |  			 			 Technical Specifications for the 5000 - hour Multiple Stress Test Setup in accordance with IEC 62730:2024  			 |  		
 		 			|  			 IEC 62730:2024  			 |  			 			 In this document, the technical requirements of the 5000h multiple stress test bench are given according to IEC 62730:2024.  			 |  		
 		 			|  			 Test Procedur  			 |  			 			 The test shall be carried out in a moisture sealed corrosion-proof chamber, the volume of which shall not exceed 20 m3.  			 |  		
 		 			|  			 Test Conditions  			 |  			 			 The cycle of stresses applied to the insulators and repeated for a period of 5 000 h is shown in Figure 3. The cycle is designed  			so that the test specimens are also subjected to the effects of temperature variation and condensation .  			 |  		
 		 			|  			 Solar Simulation  			 |  			 			 The simulated solar irradiation is provided by a xenon arc lamp with a nominal output of 6500 W and equipped with 2 boron silicate  			glass filters (see example in Figure 5) . The distance between the xenon lamp and test specimens is approximately 480 mm.  			  			A new lamp and filters shall be used at the beginning of each test. The filters and , if necessary, the lamp shall be replaced  			during the test according to the lamp manufacturer's recommendations .  			 |  		
 		 			|  			 Artificial Rain  			 |  			 			 The artificial rain shall be provided by nozzles mounted above the test specimens and outside their perimeter (see Figure 4 ). The  			average precipitation rate shall be in accordance with IEC 60060-1 . Water of a minimum resistivity of 85 nm shall be used. Each  			of the test specimens is sprayed individually.  			 |  		
 		 			|  			 Dry Heat  			 |  			 			 The chamber is heated up to 50 °C ± 2 °C; the time far the temperature to rise is 15 min as a maximum.  			  			NOTE it is recommended to heat and insulate the walls of the chamber.  			 |  		
 		 			|  			 Humidity  			 |  			 			 Nominal relative humidity: RH = 95 % ± 3 % at 50 °C.  			 |
