Packing & Shipping
• Standard Cable Drum
• Standard reel length: 2/3km/reel, other length is also available
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.
According to length of cable, we choose different type reel
(D,d,b,w1,w2) for loading cable.
Environmentally
Full comply with ISO14001, RoHS and OHSAS18001 system
Installation Recommendations
Installation procedure:
It is recommended that IEEE Std 524-1992 and our company
recommended procedures be used for the installation of OPGW.
