Tension Stringing Equipments 220KV Automatic Over Pulling Protection System

Tension Stringing Equipments 220KV Automatic Over Pulling Protection System​

The 220KV Transmission Line stringing equipments comprise of 9 ton hydraulic puller and 8 ton (2X40KN) hydraulic tensioners for 2 bundled conductors stringing. Smaller conductors can be pulled by 6 ton hydraulic puller with 7 ton hydraulic tensioner on transmission line.
 

1. SA-YQ90D Hydraulic Puller

Application:

The hydraulic puller is used to pull pilot steel wire rope for conductors in overhead transmission line construction. It is fully hydraulic controlled, easily used and maintained.

Features:

- Closed hydraulic circuit,infinitely variable speed control in both rotating directions.

- The max pulling force for stringing operation can be preset, pulling force in the rope can be read on the line pull gauge.

- Automatic over pulling protection system

- Spring applied hydraulic released brake acts automatically in case of hydraulic failure to ensure safety.

- Hydraulic oil cooling system.

- Heat treated wear-proof bull wheels

- With rigid axle for towing at high speed, the machine looks beautiful.

- Hydraulic actuated pulling rope clamp for convenient reel change.

- Integral hydraulic self-loading reel winder with automatic level wind.

Main Components:

-Engine: Cummins (China) water-cooled diesel engine.

-Main variable displacement hydraulic pump and main motor: Rexroth (German)

-Reducer: R.R. (Italian)

-Reel winder motor: Danfoss (Danish)

-Main hydraulic valves: Rexroth

-Hydraulic instruments: (German)

-Radiator: AKG (German)

Hydraulic Tensioner for 2 bundled conductors

Application:

It is suitable to string two bundled conductors or single conductor in overhead transmission line.

Features:

-Closed hydraulic circuit, infinitely variable tension force control in both directions.

-The max. tension/pull back force for conductor stringing operation can be preset, the tension /pull back force can be read from the tension gauge of machine.

-Spring applied hydraulic released brake acts automatically in case of hydraulic failure to ensure line safety

-Hydraulic oil cooling system

-Bull wheels lined with wear proof MC nylon lining segments

-With 2 hydraulic power outlets to control 2 sets of hydraulic reel stands.

-Hydraulic front jack

-The mobile control consoles make it easy for one operator to control 2 tensioner simultaneously, which facilitates 4 bundled conductors stringing operation with 2 machines.

-Mounted on trailer with rigid axle for towing at max. speed of 15 km/h
