The utility model relates to a novel high voltage test line, which comprises a test line and a tin-foil tube, wherein the test line is arranged in the tinfoil tube in a penetrating mode. The novel high voltage test line is technically characterized in that each of the two ends of the tinfoil tube is provided with an annular copper piece. The novel high voltage test line is reasonable in design, binding is carried out through pulling the annular copper pieces during wire connection, and an AC withstand voltage test, a partial discharge test and the like are carried out on power equipment, thereby not only being capable of meeting test requirements, but also being capable of avoiding a problem that tin-foil paper is broken easily, prolonging the service life of the high voltage test line, simplifying the operating mode, saving material consumption, improving the test efficiency, and ensuring the test accuracy and the test reliability. The novel high voltage test line can be widely applied to the field of insulating properties of the power equipment.
