CHARACTERISTIC
It adopts typical Hello's design. Frequency protection is distributed enough to the range of 6Hz -150Hz wide frequency zone. And in this range, there are four resonance frequencies.
FACTOR OF VIBRATION
Length of span, tensile magnitude, wind speed, wind direction, landform, and the structure and size of the cable.
NOTEThe aluminum clamps for 4D—20 are 27.0, 23.4, 20.3, 18.0, 16.0, 14.0
The aluminum clamps for 4D—30 are 27.0, 23.4, 20.3, 1 8.0, 16.0, 1 4.0
