IEC TR 61901:2016
Tests recommended on cables with a longitudinally applied metal foil for rated voltages above 30 kV (Um = 36 kV) up to and including 500 kV (Um = 550 kV)
a) Recommendations on the tests to be performed at the different stages of the cable and cable system qualification (development tests, type tests, sample tests, routine tests, after installation tests) have been provided;
b) The performance level of the tests related to the longitudinally applied metal foil which depends on the cable design has been detailed;
c) Three cable designs that represent the world production of cables with longitudinally applied metal foil have been detailed;
d) A test on the weld design has been included, following the appearance of a new cable design with smooth and longitudinally welded aluminium foil (referred to in this document as combined design);
e) An examination of the cable at the end of the type test has been included;
f) The cable system approach (cable with installed accessories) has been considered and a short circuit test with accessories has been introduced.
