Main Features
1. A typical "sandwich" conductor structure is used.
2. Full-length dense, will not form a "chimney effect".
3. The structure is compact and takes up less building space.
4. Tightly arranged conductors, overall heat dissipation, lower temperature rise.
5. The busbar at the socket does not bend, high density, low impedance.
6. Anti-error phase design to ensure that the installation phase sequence is correct.
7. The current carrying capacity is not affected by the installation location and installation method.
