Graphite copper grounding electrode

1、 Key technology: The key component graphite copper grounding electrode used in GIL has long been controlled and restricted for export by foreign companies. Through research and development, our company has achieved a breakthrough in the core technology of material preparation and realized the localization substitution of this product. The self-lubricating material grounding electrode developed by our company fully meets or even exceeds the performance of imported grounding electrodes, effectively solving the problem of metal shavings generated by the relative motion of GIL sliding three supports during thermal expansion and contraction. It can meet the mechanical life test requirements of more than 30000 times and reliably protect the safe operation of GIL.

2、 Technical capability: Our company can provide graphite copper components with any ratio (copper and graphite).

3、 Production capacity: Our company's graphite copper products adopt a one-time mold forming process and can produce 300000 pieces per year.
