Product Features
1. Adopting advanced stainless steel pipe production technology, the pipes are filled with water blocking compounds
2. Short circuit current has little mutual interference between the power grid and communication network
3. The excess length of the optical fiber and the twisted pitch of the cable core ensure that the optical cable is not subjected to force during maximum operating tension
4. Compact structure with high tensile strength
5. Similar to commonly used ground wire specifications, it is very convenient to install and can directly replace the original ground wire
