Circuit-Length Check
Circuit-Length Check
Enter the run length and the power density your design needs. The check compares them against the maximum circuit length published for each Jinyou BL model and says whether one circuit covers the run, whether the run has to be split, or whether it belongs on a skin-effect system.

Published BL maximum circuit lengths
| Model | Voltage | Rated power | Max length |
|---|---|---|---|
| BL-10-V2-Q-J3 | 220 V | 10 W/m | 200 m |
| BL-20-V2-Q-J3 | 220 V | 20 W/m | 120 m |
| BL-30-V2-Q-J3 | 220 V | 30 W/m | 100 m |
| BL-40-V2-Q-J3 | 220 V | 40 W/m | 100 m |
| BL-20-V3-Q-J3 | 380 V | 20 W/m | 300 m |
Application Notes
The skin-effect system carries a single circuit of 200 m to 10 km at 15 to 270 W per metre. Where no BL model covers the run in one circuit, the choice is extra supply points along the route or a skin-effect design.
