GB/T 4074.21-2018 Winding wires test methods—Part 21:Electrical endurance under high frequency voltage impulses
Abstract
This part of GB/T 4074 specifies the test method for measuring the high-frequency pulse voltage resistance of winding wires in normal-pressure air (also known as the corona resistance test method), including the terms and definitions of the test, test equipment, sample preparation, test procedures, test parameters, and test records. This part applies to the following winding wires: -- Corona-resistant enameled round winding wires; -- 240-grade aromatic corona-resistant polyimide film-wrapped sintered round and flat winding wires; -- Glass-filament-wrapped film-wrapped flat winding wires; -- Mica tape-wrapped flat winding wires.
