cables with an external diameter not greater than 50mm are supported every 0.6m; power cables
with an external diameter greater than 50mm are supported every 1.0m. Single-core cables arranged
in a square triangle should be tied with ties every 1.0m. For vertical installations, they should be
fixed at intervals of 1.0m~1.5m.

brackets with a vertical spacing of more than 300 mm. if this is not possible, the power cables
should be placed on the brackets above the control cables.

● The control cable should not be routed parallel to the power cable. If this cannot be avoided, a
minimum distance of 300 mm must be maintained between the control cable and the mains cable.
The control cable and the power cable should be routed in a 90-degree cross.
Note:
◆ High voltage cable ends: According to the requirements of the cable manufacturer, cable
