UL20549 - Most popular UL style of TPU jacketed cable, excellent resilience for Spiral cable
TPU Cable UL20549 has a rated temperature 80 deg C, and a rated voltage 300V. Its minimum conductor size can be 32AWG, with 2 to 80 cores twisted together, in the form of pair twisted or group twisted. Insulation could be any AWM complied material, with different insulation colours for wiring identification. TPU jacket wall thickness is as thin as 0.38mm for first level of small cable structure. It is to be adjusted as subject to the assemblied core size.
