Product Description

Eliminate or reduce the vibration caused by wind energy during the operation of optical cables to protect them and fittings. The main components include galvanized cast iron hammerheads, hot-dip galvanized steel strands, aluminum alloy wire clamps, aluminum alloy protective rods, stainless steel bolts, etc.

Product features

a.Adopting a typical Harrow design, its basic principle is dynamic energy absorption, with a frequency coverage range of 60HZ-150HZ and four resonant frequencies within this range, which can meet the needs of various types of OPGW and have very effective shock absorption effects. Vibration caused by wind energy during operation to protect optical cables and fittings.

b.The hammer head wheat harvesting suspension wire is permanently bonded and can withstand mechanical loads during installation, maintenance, operation, and other conditions.

c.Unique exterior design that does not accumulate ice or water. Easy to install, safe, and does not cause damage to wires and ground wires.

d.The shock-absorbing hammer adopts an anti corona design, which can prevent the occurrence of corona.

Ordering Notice

a.The annual average operating stress of optical cables (N). Vibration to protect optical cables.

b.Line pole/tower list and fittings.

c.Terrain and land forms (plains, hills, mountains, forests, crossing rivers).

d.Specification, model and related parameter table of optical cable: diameter (mm), ultimate tensile strength (N), unit weight (kg/m).
 

Installation of shock-absorbing hammer

Installation of shock-absorbing hammer on suspension clamp

The formula for calculating the position of shock-absorbing installation is:
L1= 0.4*D*(T/M)1/2(mm)
L2=0.7L1
L3=L4=L5=…=0.6L1
Among them: D-outer diameter of optical cable (mm)
T-Annual average operating tension (N) M-Unit weight of optical cable (g/mm)
