Preformed Helical Fitting
The Preformed Helical Fitting is mainly used in wire,ground wire installed hardware. According to the performance of the structure can be divided into:
1.Preformed Suspension Clamp:used to hang the conductors and ground wires on the perch.
2.Preformed Strain Clamp:bears all tension,connect the wire and ground wire on the tension tower
3.Splicing Fitting:used to two ends of conductor,instead of the conventional hydraulic compression splicing sleeve and pressure pipe.
4.portective fitting:used to protect the conductors and insulators,generally divided into armor rod,Repair Sleeve,vibration damper.
Material generally adopt aluminum alloy,hot-dip galvanized steel. Fasteners are hot-dip galvanized steel.
