dead end clamp

dead end clamp,preformed tension clamp,strain clamp
tensile strength (RTS) 95%
aluminum clad steel
Strength:50kN,70kN,100KN
dead end clamp,preformed tension clamp,strain clamp

Composition
:
inner pre-twisted wire, the outer pre-twisted wire, thimble, PD-type peg board, U-type hanging ring.
Purposes:
to bear all the tension will be all-dielectric self-supporting cables (ADSS) on the tower connected to the resistance to Zhang.
Features:
a. Pre-twisted wire passed through the outer ring connected gold inlay with a direct connection with the tower to withstand line loads.
b. inner preformed wire mainly for the protective role of the ADSS fiber optic cable sheath, but also as a force transmission unit:
(1). Effectively vertical clamping force transmission to the cable unit ---- Kevlar to withstand the tension and avoid excessive force cable outer sheath has been pulled.
(2). Pass axial tension.
(3). Increases the contact area with the cable, so that uniform stress distribution, no stress concentration points.
c. no more than compressive strength side of ADSS fiber optic cable under the premise of the cable holding power cables rated not lower than the tensile strength (RTS) 95%, while not damage ADSS fiber optic cable.
d. Alice end to the first treatment, to avoid scratching cable sheath.
e. high-quality aluminum clad steel material, to improve the mechanical properties of the clamp and corrosion resistance.
Technical requirements:
meet the DL / T 767-2003 All Dielectric Self-Supporting Optical Cable (ADSS) with the pre-cutter-style fittings technical requirements and test methods.
Order Notes:
a. According to the rated tensile strength of ADSS fiber optic cable, running span, diameter to select the appropriate type of NZ-based Preformed Clamp.
b. the number of configurations as follows: 1 set / Terminal tower; 2 sets / Tension tower.
c. Clamp Strength:50kN,70kN,100kN and so on.
