If I can remember correctly, the max EU/t a reactor can reach is 2048EU/t. So I'd say just pop a HV-Transformer onto it and then glass fibre cable leading to whatever. If you have none of that, then either use HV cable or also place an MV-transformer and use gold cable. Though I highly recommend glass fibre cable due to it's very low EU loss rate per block.
EDIT: In case you don't know
HV Cable (fully insulated) - 1 EU lost every 1.25 blocks. Max intake is 2048EU/p (EV.)
Gold Cable (fully insulated) - 1 EU lost every 2.5 blocks. Max intake is 128EU/p (MV.)
Glass Fibre Cable - 1 EU lost every 40 blocks. Max intake is 512EU/p (HV.)
