Technical Specifications for the 5000 - hour Multiple Stress Test Setup in accordance with IEC 62730:2024.

Product name:
Technical Specifications for the 5000 - hour Multiple Stress Test Setup in accordance with IEC 62730:2024.

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 .

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.

Salt fog calibration:
The calibration will be carried out before the start of the test.
At least two clean collecting receptacles with a collecting area of 8 000 mm2 ± 2 000 mm2 and a maximum height of 100 mm each are placed as close as practical to the position of the ends of the test object. The receptacles are positioned in such a way that they are not shielded by the test specimens and to avoid dripping from the construction elements of the chamber or another source.
They should collect between 1,5 ml and 2,0 ml of precipitation per hour (corrected to 8000 mm2 collecting area) averaged over a minimum period of 16 h.
NOTE The flow rate necessary to obtain such precipita tion (typically of the order of 0,3 l/m3h based on a chamber not larger than(15 m3) should be noted. (The water flow rate is defined in l itres per hou r and per cubic meler of the test chambe r volume. )
Subsequently du ri ng the test, the flow rate should be checked at least every 100 h and should remain within ± 25 % of the initial value.
it is not permitted to re-circulate the water.

8- Warranty conditions will be specified
9- Spare parts will be provided for 10 years
10- Consumables list will be provided

Selection of Packaging Materials: Selection of Packaging Materials 1. Use sturdy and durable packaging boxes to prevent equipment
damage caused by collision or compression during transportation. 2. The interior is filled with shockproof materials, such as
foam, air cushion or pearl cotton, to ensure that the equipment will not shake in the packaging box. 3. For fragile or sensitive
components (such as electrodes, display screens, etc.), package and secure them separately to avoid damage during transportation.
Mode of Transport: 1. Prioritize choosing professional logistics and transportation companies to ensure safety and reliability
during transportation. 2. For long-distance transportation, land or sea transportation should be used to avoid the potential
impact of air pressure changes on equipment during air transportation.
