4. Packing and Shipping
The OPGW shall be tightly and uniformly wound on a strong wood-iron reel which conforms to ANSI/AA 53-1981 or equal. The reel shall be lagged with stout wood-iron battens so as to prevent the OPGW from damage in ordinary shipping, handling, storage and stringing operations.
Drawing of Reel
According to length of cable, we choose different type reel (D,d,b,w1,w2) for loading cable.
5. Environmentally
Full comply with ISO14001, RoHS and OHSAS18001 system
