24 Core ADSS Fiber Cable 120M SPAN SM G652D Single Jacket

ADSS fiber optic cable is a type of optical fiber cable that is strong enough to support itself between structures without using conductive metal elements. It is used by electrical utility companies as a communications medium, installed along existing overhead transmission lines and often sharing the same support structures as the electrical conductors. Design different specifications according to span, voltage level and tensile force(MAT).

Max Span: 120m   MAT=3300N

Weather conditions: 25m/s wind speed + 0mm Ice Load

Cable Section Design:


Main Features:
1. High tensile strength
2. All dielectric structure and semi-dry core design
3. Small diameter and light weight

Application:
The design of ADSS cable takes full account of the actual situation of power lines and is suitable for different grades of high voltage transmission lines.  Polyethylene ( PE ) sheath can be used for 10 kV and 35 kV power lines.  For 110 kV and 220 kV power lines, the optical cable hanging point must be determined by calculating the electric field strength distribution and the electric mark ( AT ) outer sheath must be adopted.  At the same time, the amount of aramid fiber and the perfect stranding process were carefully designed to meet the application requirements of different spans.
