説明
GYTC8S図 8 Cable is Self-supporting GYTC8S 2-24 core fiber optic complying with Standard YD/T 1155-2001 as well as IEC 60794-1.
GYTC8S図 8 Cable Product Overview
It is a typical self supporting outdoor fiber optic cable with features of moisture resistance and crush resistance suitable for aerial application. The structure of the GYTC8S fiber optic cable is a 250μm optical fiber sheathed into a loose tube made of high-modulus material, which is filled with a waterproof compound. The center of the cable core is a metal reinforcement core (which can also be non-metallic, such as FRP, 等), and the loose tube (and filler rope) is twisted around the center reinforcement core to form a compact round cable core. In the form of longitudinal wrapping, a layer of plastic-coated aluminum strip (APL) is added to the sheath outside the cable core, and finally the polyethylene sheath is extruded with the steel strands to make its cross-section “8” shape.
