GTB Series AC DC Hipot Tester

GTB series dry typed AC DC Hipot Tester is composed with dry-typed test transformer and power controller it is a basic testing device for power stations power supply/distribution system and technological institutions. It is used for dielectric withstanding voltage test under designated voltage to assess the insulation status and defect as well as the over-voltage withstanding ability of electric appliances electrical equipment and insulated materials.
GTB Series dry-typed test transformer using advanced production process coil winding epoxy vacuum casting and CD-type core of the new technology. Comparing to the similar oil-immersed transformer products it with reduced weight and volume significantly increase the degree of dielectric strength and moisture resistance and also weaken the magnetic flux leakage effectively and strengthened the transformer withstand circuit current anti-shocking greatly.

Product characteristics
(1) Comparing to the similar oil-immersed transformer products it has lower weight and volume increase the degree of dielectric strength and moisture resistance and also weaken the magnetic flux leakage effectively and strengthened the transformer withstand circuit current anti-shocking greatly.
(2) The connecting wire is simple and intuitive easy to use.
(3) The insulation is reliability and with over-current protection function.
(4) Equipped with handle and four movable wheels which is convenient for handling equipment on site.
