1.Vibration damper for OPGW
Vibration damper makes use of rotation & swing of the two-end hammer heads for generating friction damping force from the mutual slippage among the galvanized iron wire strands to consume the swinged energy. It is adopted preformed rod structure in which the holding strength between the installation of vibration damper to preformed rods and the conductors evenly spread the distance from 30 to 60cm on the length area, effectively protecting the conductor by avoiding the stress concentraton of the latter.

Vibration damper

2.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.

3.Function of vibration
Length of span, tensile magnitude, wind speed, wind direction, landform, and the structure and size of the cable.

What is ADSS and OPGW cable

What is ADSS and OPGW cable
OPGW cable is suit for installation on new power lines with double function of ground wire and communication, especially for installation on normal voltage and extra high voltage power lines. OPGW can replace conventional ground wire of old power lines with increasing fiber communications function. OPGW cables conduct short circuit current and provide lighting resistance. OPGW cables are usually two structures. The central tube OPGW cable can obtain maximum optical fiber excess length in a smallest steel tube. The diameter of stainless steel tube is bigger than that of ACSR wire and aluminum alloy wire. The stainless steel tube is placed in the center of the stranded structure of the OPGW cable. Stranded OPGW cable can obtain secondary excess length; the diameter of stainless steel tube is consistent with diameter of aluminum alloy wire.
