1. Principle

     By applying DC excitation current to change the core magnetic permeability , so as to change the reactance value of the arc-suppression coil.

2. Features

 2.1 The resistor cabinet adopts Al-Zn coated plate, stainless plates or cold-rolled steel plates, featuring beautiful appearance and corrosion resistance.

  2.2 Stable reliable and endurable

  2.3 Higher regulation precision and fast reliable

  2.4 Dynamic compensation with damping resistors not required

  2.5 Electric controlled stepless continuous and static adjustability

  2.6 Simple structure, space-saving, low failure rate, easy maintenance and basically free of maintenance.
