2025-09-02 What are the technical point···Mineral cables are manufactured in limited lengths, requiring intermediate connectors when the cable run is insufficient. However, the more joints a cable has, the more capped ends it has, making it difficult to guarantee the cable's insulation resistance. Furthermore, intermediate connectors ar
