The optical fiber drawing-tower production equipment converts optical fiber preforms into optical fiber using a preform feed system, heating system (induction-furnace heating), cooling system, diameter-gauge system, curing system and take-up system. The drawing-tower production equipment has 4 lines on one tower for a small footprint, maximizing production efficiency at minimal cost. Efficient heat dissipation reduces production costs and offers advantages in improving product quality and market competitiveness. Equipment components: preform-feed operation display: 1 set; drawing-rate electrical cabinet: 1 set; drawing induction furnace: 1 set; centralized feed unit: 1 set; LED electrical cabinet: 1 set; LED curing furnace: 1 set; operation cabinet: 1 set; take-up machine: 1 set.
