Packing and Shipping
OPGW cable is tightly and uniformly wound on strong wood-iron reels compliant with ANSI/AA 53-1981 standards. Reels are lagged with stout wood-iron battens to prevent damage during shipping, handling, storage and stringing operations.
Reel selection (D,d,b,w1,w2 dimensions) is determined by cable length requirements.
