It requires no messenger wire, withstands high electric fields up to 220 kV, and supports spans from 50 m to over 1,500 m — making it the most versatile aerial cable for telecom, power grid, and rural broadband projects. 1 Fiber Optic Tangent: Used as cable suspension hardware only on spans less than 350 feet when the angle of change, either horizontal or vertical, is less than 15°. The tangent clamp is designed to hold the cable. ADSS cable stands for All-Dielectric Self-Supporting Fiber Optic Cable. The term "all-dielectric" means the cable contains no metallic conductive components, while "self-supporting" indicates that the cable can span between poles or towers without requiring a separate messenger wire. ” Why? Because it allows you to string fiber optic data lines on existing high-voltage towers without shutting down the power and without worrying about lightning induction. Uneven. ADSS fiber cable works in an overhead state with two points of support over a large span (usually hundreds of meters, or even more than 1 kilometer), which is completely different from the traditional concept of "overhead" (the standard overhead suspension wire hooking procedure of the post and.
