Current transport properties in 200 A-200 m-class IBAD-YBCO coated conductor (CC) have been investigated over a wide range of temperature and magnetic flux density up to 26 T. YBCO CC fabricated by reel-to-reel pulsed laser deposition equipment with a multi-plume and multi-turn deposition system showed high critical current of 245 A in length of 212.6 m. Critical current density, J(c,) in 5 T parallel to c-axis at 65 K and 4.2 K were 0.44 MA /cm(2) and 5.5 MA /cm(2), respectively. Moreover, even in very high magnetic flux density, the superior J(c) property remains at lower temperature, e.g. J(c) at 4.2 K in 26 T was 2 MA /cm(2). We also showed analytical expressions of electric field vs. current density (E-J) characteristics based on a framework of percolation model and scaling law of the flux pinning properties. Using the expressions, E-J characteristics and J(c) value at any conditions of temperature and magnetic flux density can be predicted quantitatively.
