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.
