TD ≤10 m
RVV4 * 0.2 mm ^2
10 m < TD ≤30 m
RVV4 * 0.5 mm ^2
30 m < TD ≤50 m
RVV4 * 0.75 mm ^2
50 m < TD ≤100 m
RVV4 * 1.5 mm ^2
On the rear panel of the indoor station,
four-wire interface A and four-wire
interface C compose a cascading group;
and four-wire interface B and four-wire
interface C compose a cascading group.
