The 10kV gel-filled middle joint explosion-proof box, made from fiberglass material, is designed for the safety protection of power cable middle joints. It effectively prevents the spread of high-pressure airflow, flames, and debris during cable faults, ensuring that surrounding electrical equipment or personnel are not harmed. This explosion-proof box provides excellent fire, water, and explosion resistance, and can operate stably in harsh environments, preventing secondary accidents caused by cable joint failures. Its acid resistance, alkali resistance, and corrosion resistance make it suitable for various environments, ensuring the safe and stable operation of the power system.
