40KN SA-YZ40A hydraulic Tensioner 30KN Hydraulic Wire Tension Device



Product Introduction


The overhead transmission line tension stringing equipments are widely used in overhead transmission Line Conductor or OPGW tension stringing project. We are the only one to supply whole set of stringing equipment and tools for transmission line construction in China.

We could supply whole set of stringing equipment and tools for transmission line up to 1000KV construction.




a.They are widely used for stringing the conductors & cables(OPGW,ADSS,500kv tractiong rope,LGJ series,etc.).

b.This machine has a set of tension early warning system,which can automatically adjust the speed according to the undue load or friction produced on the line and can keep the tension at setting value.

c.Tension or pulling force can be preset,spring applied brake,reliable overhead protection mechanism,easy to operate.




30KN Hydraulic wire tension device  adequate to tension releasing various conducts and earthwires .and also useful for tension releasing OPGW optic cable compounded earthwire and ADSS self–stand optic cable  etc .
