Abstract A static induction device with excellent insulation performance in surging voltage is disclosed. The coil unit connected to terminals is surrounded by electrostatic shielding insualtion layer. Said coil unit and its shielding layer and another coil unit are surrounded by another electrostatic shielding insulation layer to form a sequential embedded structure. Each electrostatic shielding layer is composed of a central insulation layer made of fibrous board and two electric conduction layers at both sides of said insualtion layer. Regulating the capacitance of each electrostatic shielding insulation layer can control the potential distribution under surging voltage.
