Detailed Product Description
DK-Ln decoupling device mainly is arrester used for the voltage divider between B and C types of arresters, direct series for the coordination of the first and second levels of the arrester action, to achieve the best security protection, to extend the life of surge arresters.
(1)Slows down the rise speed of thunder and lightning transient state overvoltage, coordinate different specification and increases the wire induction reactance;
(2) The concentrated inductance supplements the conductor length, low loss unsaturated;
(3) The standard guide rail installment, facilitates to install in the standard distributing box
(4) Applies to lightning protection zone between LPZ 0A and LPZ 2, in the smallest space to achieve the protective effect.
