Introduction High frequency ac spark tester is widely used for online detecting wire and cable insulation and voltage resistance, hole and fracture, which is an important process and directly influences the entire cable quality. Compared with conventional types, this machine has advantages of space saving, easier operating, faster detecting speed, which is more suitable for modern production.
