Overhead Line Stringing Equipment 20kN Single-wheel Stringing Pulley Blocks
Introduction:
Stringing pulley block is a special equipment for supporting various conductors and ground wires in overhead transmission line stringing construction, which plays a supporting role for ground wires. It does not damage wires and has small friction coefficient. It can pass through traction plates, connectors and pressure nozzles smoothly.
Application:
Suitable for laying out single conductor overhead transmission line.
Description:
1. We manufacture a lot of models for different uses in the overhead transmission line construction.
2. The stringing pulleys are used to support conductors, OPGW, ADSS, communication lines, etc.
3. The sheave of the pulley blocks are made from high strength MC nylon, or aluminum materials, and the frame of blocks are made of galvanized steel. The lateral ones are mounted on ball bearings.
4. According to the customer's demand, aluminium wheel or MC nylon wheel can be selected.
Remarks:
All kinds of pulley blocks can be manufactured according to the customers's requirements.
