Product Description

Our 822 series large diameter stringing blocks are professional tension stringing tools for overhead high voltage transmission lines, widely used for stringing LGJ630 ACSR conductors. Block dimension: Φ822×Φ710×110 mm. Multiple specifications from single sheave to 9 sheaves are optional. The 9-sheave model 10148 adopts assembled separable structure, the conductor sheave and middle steel sheave can be separated, greatly reducing transportation weight.

We supply 3 kinds of sheave materials: MC nylon, strengthened nylon and cementation aluminous sheave. Some models adopt cast steel middle sheave + MC nylon conductor sheave, to balance wear resistance and conductor protection. Smooth rotation, low friction, effectively avoid conductor scratch and damage during stringing work. Suitable for power transmission tower erection, overhead conductor tension stringing, power grid renovation and EHV line construction projects.
