ZGJZ1 (TY) High Efficient Resistance Reducer
General
The ZGJZ1(TY) High Efficient Resistance Reducer is made from natural inorganic substances with features of stable performance, nontoxicity and harmlessness, and nonmetal materials protecting the metal grounding body. This product is characterized by the good conductivity, resistance to high impacts and easy construction. It is suitable for lightning protection grounding, working grounding of various electrical and electronic equipment, protective grounding, and antistatic grounding of explosive and flammability equipment and system, which can reduce the grounding resistance of grounding device, safe and reliable.
