Do you know the different types and uses of stringing pulleys?

The Stringing Pulley is divided into ground cable pulley, cable pulley, skyward pulley, nylon pulley, cable conductor Stringing Block, large-diameter Stringing Roller, dual-purpose paying off cable pulley, ground wire paying off cable block, and Lifting Pulley. The Stringing Block is mainly used for protection when laying cable conductors, saving time and labor. Among them, the ground corner cable pulley is mainly used for changing the direction of cable extension to protect the cable from friction.

1. Classification and application of stringing pulley
According to the material, there are two kinds of aluminum wheels and MC nylon wheels, and the styles are divided into tube type and plate type.
Application of large diameter stringing pulley: it is used to lead and pay off single conductor, double split conductors, and four split conductors (the intermediate wheel can be cast steel wheel or nylon wheel). Characteristics: it is suitable for tension stringing.
Ground wire stringing pulley: it is suitable for laying off lightning wires or crossing steel strands, including steel and MC nylon.
Stringing pulley specially used for optical cable:
(1) For laying off OPGW composite ground wire optical cable or ADSS self-supporting optical cable, a small groove is equipped at the bottom of the wheel groove, which is specially manufactured to protect the optical cable;
(2) The wheel is made of MC nylon by die casting, which will not damage the outer skin of the optical cable during paying off.

2. According to the different applications, there are linear type and corner type cable blocks. The stringing pulley is divided into flat type, bridge type, and steel pipe frame type according to the different construction sites.

There are many kinds of cable pulleys, which are not only used for different purposes, but also in different shapes. When the cable wants to change direction or encounters an angled object, it is necessary to use the corner cable pulley. The aluminum wheel is made by die casting, and the nylon wheel is by casting with a large load. All bearings are high-strength ball bearings, which fully reduce the friction between the stringing pulley and the cable. Save time for your construction.
