Data transfer system |
摘要 |
The transmission method involves feeding an electrical cable (16) along the drill rod (11), with cooperating coupling elements fitted to the end of the cable and incorporated in a drive adapter (10) at the end of the drill rod. The coupling elements provide axial relative movement between the cable and the electrical load. |
