Shanghai Gengyun Industrial Co., Ltd
The design of adss fiber cable fully considers the actual situation of power lines and is suitable for different levels of high-voltage transmission lines. For 10kV and 35kV power lines, polyethylene (PE) sheathing can be used. For 110kV and 220kV power lines, the all direct self-supporting optical cable hanging point must be determined by calculating the distribution of electric field strength and using an anti electric trace (AT) outer sheath. At the same time, the amount of aramid is carefully designed and the twisting process is perfected to meet the application requirements of different spans.
(Self supporting overhead)
Standard
Adss fiber cable comply with IEEE 1222 and IEC 60794-1 standards.
Feature
1, Can be installed continuously with electricity;
2. Adopting AT sheath, with superior resistance to electric traces;
3. Lightweight and with a small cable diameter, it reduces the impact of ice and wind, as well as the load on towers and supports;
4. Large span, with a maximum span exceeding 1000 meters;
5. Adss fiber cable has excellent tensile performance and temperature characteristics;
6. Expected life span greater than 30 years;
