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.

Configuration Parameters

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.
