Tender Details

The subject of the order is the purchase of research services: 1) Alternating voltage test at mains frequency in rain for insulators with a rated voltage of 110 kV and 220 kV and switching voltage test in rain for insulators with a rated voltage of 400 kV. As part of the test, the withstand voltage should be checked will determine the jump voltage. The test should be carried out in accordance with the requirements of PN-EN 61109, p. 11.1, according to the methodology given in PN-EN 60060-1, p. 6.3.2. Number of test objects: 400kV composite insulators 4 pieces, 220kV composite insulators 14 pieces, 110kV composite insulators 11 pieces. 2) Check boundary surfaces and connections - a test in the field of structural tests of composite linear insulators. The insulator should be checked by subjecting it to a steep-front impulse voltage test. This test should be carried out in accordance with the requirements specified in the PN-EN 62217 standard, section 9.2.7.3., but without carrying out tests preliminary to this trial. In this test, an impulse voltage of 2000 kV/s should be used. Number of test objects: Composite insulators 400kV 2 pieces, Composite insulators 220kV 7 pieces, Composite insulators 110kV 6 pcs...
