Conductor Pulleys with aluminum alloy sheaves are used for stringing aluminum conductors or OPGW cables on overhead transmission line.
Conductor Pulleys with aluminum alloy sheaves for stringing overhead transmission line
1. Die-cast process of conductor pulleys make Aluminum alloy sheaves with clear shapes and thin walls and deep cavities. Because molten metal adheres to high fluidity at high pressure and speed, there is no pores and cracks in the casting sheaves.
2. Aluminum die-casting can reduce the weight of parts.
3. The temperature and pressure of aluminum alloy molds are much higher than those of normal castings, and the accuracy requirements are extremely strict. The strength of sheaves are higher than normal castings and nylon sheaves.
4.Aluminum die-casting has high scale accuracy, which can reach IT11-13, sometimes IT9, and the surface roughness can reach Ra0.8-3.
5. The lined neoprene can protect the surface of aluminum conductors and OPGW cables.

Application: It is suitable to string stranded aluminum and ACSR conductors or OPGW on tangent structures. Compression sleeves, swivel connectors, and pulling rope connectors can pass through the groove of big rollers. The sheave is made in aluminum alloy. The size of 300mm, 408mm, 508mm, 660mm, 822mm aluminum alloy sheave can be lined with neoprene.
All the series of conductor pulleys can be installed with grounding rollers.
