ZGF type high voltage generator of direct current is a kind of versatile power equipment of high voltage. This apparatus is steadier and more credible. It can protect switching on of null electric voltage, excess voltage, and excess current, which can protect apparatus and testing apparatus immediately. And this apparatus owns wonderful advantages, such as small, light, portable, easy to manipulate, continuously adjustable, safe, and reliable. So it is fit for:

˙field constant-current high voltage test of department of power supply, such as electric power cable of direct current withstand voltage and compromising test, tests of 1mA reference current and electric conductance current of magnetic blow out arrestor and zinc oxide lighting arrester.

˙As laser source of power, and for electrostatic spray painting and electrostatic textile and so on.

˙The other situation of the required direct current high voltage.
