Introduction

                                   ■   The  fibers are placed in a loose tube made of PBT. The
                                        tubes are filled with a water-resistant filling compound.
                                        A steel wire locates in the center of core as a metallic
                                        strength member. The tubes (and fillers) are stranded
                                        around the strength member into a compact and circular
                                        cable core. After PSP is applied around the cable core ,
                                        this part of cable accompanied with the stranded wires as
                                        the supporting part are completed with a PE sheath to be
                                        figure 8 structure. This kind of cable is specifically applied
                                        for self-supporting aerial installation.
