Audited Supplier Stainless steel optical unit is in the inner position. Compared with the central stainless steel tube, larger cable diameter and larger capacity of the optical fiber.
It is applicable to new aerial power route to satisfy the needs for big conductors and high voltage transmission, and is used to conduct large fault short circuit current to provide anti lightning protection.

OPGW optical cable is mainly used on 500KV, 220KV and 110KV voltage level lines. It is mostly used on new lines due to the influence of line power outage and safety.
The applicable characteristics of OPGW are:
(1) The line with high voltage exceeding 110kv has a large gear distance (generally above 250M);
(2) Easy to maintain, easy to solve the problem of line crossing, its mechanical characteristics can meet the large line crossing;
(3) The outer layer of OPGW is metal armor, which has no effect on high voltage electrical corrosion and degradation;
(4) OPGW must be powered off during construction, and the power loss is large, so OPGW should be used in new high-voltage lines above 110kv;
(5) In the performance index of OPGW, the greater the short-circuit current, the more need to use a good conductor as armor, the tensile strength will be reduced accordingly, and in the case of a certain tensile strength, to increase the short-circuit current capacity, only increase The metal cross-sectional area leads to an increase in cable diameter and cable weight, which poses a safety issue for the strength of the line tower.
