1. Overview AL-ZRC series special self-controlled RC absorber (abbreviated as AL-ZRC) is a new patented product independently developed by our company to meet the complex environment needs of metallurgical smelting and reactor sites. It can suppress overvoltages in the range of 48Hz-1000KHz, which is different from the overvoltage protectors on the market that can only suppress overvoltages in the range of 48Hz-62Hz. It is specially used in voltage systems of 66KV and below, effectively limiting the damage of operating overvoltages to inductive loads such as circuit breakers and reactors. It is suitable for fields such as metallurgical smelting and reactor use. 2. Product features 1. Professional protection In medium-voltage power grids, vacuum electrical products (vacuum circuit breakers, vacuum contactors, vacuum load switches, vacuum reclosers, reactors, etc.) are easy to cause cut-off overvoltage, multiple restrike high-frequency overvoltage and three-phase simultaneous breaking overvoltage when closing and closing inductive loads (generators, motors, reactors, transformers, etc.) due to their strong arc extinguishing ability.
