Embodiment Construction
[0023] In this example, if image 3 As shown, the composition of a double-sided ADSS optical cable tension clamp includes a bilateral tension pre-twisted wire group, a double-sided tension inner twisted wire and a parallel groove clamp 3, which is applied to two ADSS optical cables 6 facing each other at the top. Among them, the bilateral tension pre-twisted wire is composed of the left pre-twisted wire group 2a, the right pre-twisted wire group 2b and the middle receiving rod 1 to form a whole, and the bilateral tension-resistant inner twisted wire and the parallel groove clamp 3 are used as the accessories of the clamp; figure 1 As shown, an intermediate receiving rod 1 is set on the tensile pre-twisted wire group, so that the tensile pre-twisted wire group is divided into a bilateral structure of the left pre-twisted wire group 2a and the right pre-twisted wire group 2b; the middle receiving rod 1 It can be used for suspending the optical cable splice box 7; it can also be ...

The invention discloses a two-side ADSS (all-dielectric self-supporting optic fiber cable) tension clamp and an application thereof. The two-side ADSS tension clamp is characterized in that an intermediate connecting bar is arranged on tension performed armor rod sets; parallel groove clamps are arranged on a left preformed armor rod set and a right preformed armor rod set which are arranged at two ends of the intermediate connecting bar, respectively, and left cable outlet clearance and a right cable outlet clearance are formed; two ADSSes with tops opposite are wound by inner armor rods, and an ADSS tension fitting with a protection structure is formed; the ADSSes with the protection structures are arranged on the left preformed armor rod set and the right preformed armor rod set respectively, with the tops thereof penetrating the left cable outlet clearance and the right cable outlet clearance, and accordingly two ADSSes with the tops thereof opposite are in suspending abutting structure. According to the arrangement, repairing efficiency of the ADSS is increased, and repairing cost of the ADSS is reduced.
Description
technical field [0001] The invention relates to the field of ADSS optical cable communication, in particular to a double-sided ADSS optical cable strain clamp and its application. Background technique [0002] Most of the currently running ADSS optical cables pass through hilly and mountainous areas, and there are more than ten optical cable failures caused by squirrels biting the fiber core of ADSS optical cables every year. Due to unfavorable factors such as unreserved lines for ADSS optical cables and inability to bear force at the optical cable joint box, the construction of emergency repair ADSS optical cables is complicated. The traditional emergency repair process needs to cast 1-2 line span ADSS optical cables, and the fusion splicing repair can only be performed after the optical cables are fastened. The emergency repair is restricted by the terrain and environment, which requires a lot of manpower and material resources, and the work period for the repair of the o...
