With the laying and upgrading of information construction projects at home and abroad, more and more communication networks used by OPGW are used in different environments. Some are laid between mountains and some are erected in coastal areas.
Compared with the mountain environment, the coastal area environment is relatively more demanding, and the sea wind blowing from the sea to the ground carries more moisture and higher humidity than the wind blowing from the ground. Moisture in the sea breeze can undergo redox reactions with metals, which is greater than that of other winds.
Another point is that the temperature difference on the sea surface is small. Generally speaking, the time when the sea breeze is more corrosive is around summer. At this time, the sea surface temperature is low, so the wind blowing to the land is formed due to reasons such as sunshine, temperature, and evaporation. At this time, the wind of the sea breeze is stronger than the general wind or the sea breeze at other times, so the force is greater. At the same time, the salinity carried by the sea breeze is also one of the factors that corrode OPGW.
In response to this situation, the corrosion-resistant OPGW designed by Hunan GL Technology Co., Ltd:
1) The aluminum-clad steel wire and the aluminum alloy wire are subjected to finished product peroxidation treatment to form an alumina protective film on the aluminum surface, which is resistant to strong acid and alkali, and is suitable for high-strength salt spray corrosion environment.
2) Use cold-filled anti-corrosion ointment to prevent electrochemical corrosion.
GL's OPGW can effectively prevent the sea breeze from corroding optical cables, and has been successfully used in the high-corrosion areas of the Aegean Sea. The designed OPGW successfully passed the Type Test of Shanghai Cable Research Institute, according to IEEE1138-2009: 6.4.3.8 , test number CT16-2933.
In the laboratory of the Shanghai Cable Research Institute, the seaside environment is simulated, and the pH value is 6.5~7.2 under the environment of 35±2℃, and the PH value is kept at 6.5~7.2 for 1000 hours, and then the corrosion is detected. ideal effect.
