20KN Hydraulic Cable Tensioners Puller Winch Machine for Line Transmission

SA-YZ20 20KN Hydraulic Tensioner Puller Winch Machine for Line Transmission

Product Information

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.

The sets include hydraulic pullers and hydraulic tensioners. We have developed big tension stringing equipment for overhead transmission line up to 1000KV for  8 bundled conductors stringing. Our hydraulic pullers have 30, 40, 60, 90, 180, 220, 250, 300, 360 KN pulling capacity, our hydraulic tensioners have 7.5 KN, 20, 30, 40, 2X35, 2X40, 2X50, 2X70, 2X80, 4X40, 4X45 capacity.

We could supply whole set of stringing equipment and tools for transmission line 220KV,500KV,1000KV construction.

Uses

it 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 .

Description

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.

Features

1. Bullwheel with wearproof MC nylon lining segments.

2. infinitely variable tension control and constant tension conductor stringing .

3. spring applied hydraulic released brake acts automatically in case of hydraulic 

failure to ensure safety.

4. It realize to work without disipation of energy and low noise.
