stranded copper cable

When working with Type G-GC portable power cables, one of the most frequently asked questions by installers and maintenance technicians concerns the proper connection of the ground check conductor, often called the pilot wire. This seemingly simple question touches on one of the most critical safety systems in mining and heavy industrial electrical installations. Understanding not just where this wire connects, but why it exists and how it functions as part of a comprehensive ground fault protection system, is essential for anyone working with mining equipment electrical systems. 在使用Type G-GC便携式电源电缆时，安装人员和维护技术人员最常问的问题之一是关于接地检查导体（通常称为导线）的正确连接。这个看似简单的问题涉及到采矿和重工业电气安装中最关键的安全系统之一。
