Product Description

Our 660 series large diameter stringing block is professional overhead line stringing equipment for power transmission & distribution construction. We supply single, triple, five, seven and nine sheave types, with MC nylon, cemented aluminous and cast steel sheave optional. The sheave can be customized with rubber coating to protect conductors well. The frame adopts hot-dip galvanized steel, anti-rust, high strength, matched with heat-treated shaft and precision ball bearings, smooth rotation, low friction, avoid scratching conductors, OPGW, ADSS and communication cables.

We have 20 years experience manufacturing overhead line stringing tools. All blocks are strictly tested before delivery, widely used in high voltage transmission line, bundled conductor stringing project.

Application Scenarios
