Description :
OPGW fiber optic cable manufacturer OPGW power communication fiber optic cable
Characteristics: 1. Lines with high voltage exceeding 110kV have a large span (usually above 250M).
2. Easy to maintain, easy to solve for line crossing problems, and its mechanical characteristics can meet the requirements for large line crossings.
3. The outer layer of OPGW is metal armor, which has no effect on high-voltage corrosion and degradation.
4. OPGW must be powered off during construction, and the losses caused by power outages are significant. Therefore, OPGW should be used in the construction of new high-voltage lines above 110kV.
In the performance indicators of OPGW, the larger the short-circuit current, the more good conductors are needed for armor, which correspondingly reduces the tensile strength. However, in the case of a certain tensile strength, to increase the short-circuit current capacity, the only way is to increase the metal cross-sectional area, resulting in an increase in cable weight and cable diameter, which poses a safety issue for the strength of the transmission tower.
Structure: OPGW optical cables are mainly used on 500kV, 220kV, and 110kV voltage level lines. Due to factors such as power outages and safety concerns, they are often used on newly built lines. There are three main categories: aluminum steel type, aluminum skeleton type, and (stainless) steel pipe type.
Ordering notice: 1. The usage scenarios need to be provided, such as: mountains and forests, crossing rivers, crossing bridges, underwater, pipelines, wind farms, etc.
2. Design requirements for core count, model span, tensile strength, cross-section, material requirements, etc. must be provided.
3. The types of optical cable requirements, including center tube structure and layer twisted structure, need to be provided.
If customized, other known detailed technical parameters or design drawings need to be provided.
