OPGW Clamp: Composition: inside the twisted wire, twisted wire outside, thimble, PD-type siding, U-shaped hanging ring multi-strand aluminum grounding lines. Purpose: to bear the full tension. The OPGW cable is connected to the terminal tower, tower and cable continued strain on the tower. Features:. A twisted wire through the outer ring embedded link fittings directly connected with the tower, to bear the load line. . b within the skein of OPGW cable protective effect, the main role are: (1) effective longitudinal compression force to withstand the tension of the cable unit of a Kevlar, the cable outer sheath to avoid excessive force being strained. (2) transmitting axial tension. (3) increasing the area of ??contact with the cable, so that the stress distribution uniform, no stress concentration points. c. Under no more than OPGW cable side compressive strength of the premise, to have greater holding power cable, can withstand greater tension. d. for the holding force of OPGW cable is not less than the ultimate tensile strength (UTS) of 95%, perfectly suited to the needs of the cable erection.
