Description :
OPGW optical cables can adopt aluminum tube type, aluminum skeleton type, and (stainless) steel tube type structures according to user needs. The optical fibers are sheathed in stainless steel sleeves, surrounded by aluminum clad steel wire (AS wire) and wrapped with aluminum alloy wire (AA wire) layers to form cables. When the first two structures of OPGW are subjected to short-circuit current impact, the aluminum tube and aluminum frame will generate relatively high temperatures and diffuse inward, thereby affecting fiber transmission and even fiber breakage, while the stainless steel tube type significantly improves the situation. If the structure contains aluminum, after exceeding 200 ℃, the aluminum will first undergo irreversible plastic deformation. At the same time as the structure is damaged, the increased sag of OPGW not only cannot maintain a safe distance from the conductor, but may also collide with the conductor. If it is an all steel structure, it can work at 300 ℃ for a short time.
Product features: The design of OPGW optical cable fully considers the actual situation of power lines and is suitable for any newly built high-voltage transmission line. We can carefully design matching products to meet the needs of users with different tensile strengths and short-circuit currents, in order to achieve a good balance between mechanical and electrical performance.
Product application: OPGW optical cables are mainly used on 500KV, 220KV, and 110KV voltage level lines. Due to factors such as power outages and safety, they are mostly used on newly built lines. Lines with high voltage exceeding 110KV have a large span (usually above 250M). Easy to maintain, easy to solve for line crossing problems, and its mechanical characteristics can meet the requirements for large line crossings; The outer layer of OPGW is metal armor, which has no effect on high-voltage corrosion and degradation; OPGW must be powered off during construction, as power outages result in significant losses. Therefore, OPGW should be used in the construction of new high-voltage lines above 110KV.
