adss optical cable factory teaches you how to prevent electrical corrosion of adss optical cables. ADSS optical cables generally refer to all-media self-supporting optical cables (combined optical cables).
All-dielectric self-supporting optical cable (ADSS) has the characteristics of metal-free, tension-resistant, self-supporting, high insulation, non-inductive, thin diameter, light, easy to construct and economical.
It is a composite optical cable made by winding the optical fiber bundle around the central strengthening member and taking protective measures such as insulation, waterproofing, reinforcement, and sheathing.
Features: full dielectric, no metal, non-conductive; small cable diameter, large pulling force; low linear expansion coefficient, wide applicable temperature.
Prevention of electric corrosion: The fundamental reason for the occurrence of electric corrosion is that the ADSS optical cable is in a high electric field or high potential environment. Therefore, the basic measure to prevent or reduce the damage caused by electric corrosion to the ADSS optical cable is to select the space potential. Hang the ADSS optical cable at a location that is not too high and where the potential gradient is not too large.
In addition to this measure, the following methods can also prevent the occurrence of electrical corrosion: (1) Spray "water-increasing agent" on ADSS optical cables and related components (such as anti-vibration whips, etc.) to make them They are "water-proof".
In this way, dry zones can be avoided on the outer sheath of the ADSS optical cable and "dry zone arcs" can be prevented.
(2) Spray insulating agents such as mica mist powder-based or ceramic powder-based on ADSS optical cable components to prevent the occurrence of "dry strip arc".
