8 Ton Hydraulic Tensioner is used for two or single conductors stringing on 275 or 330 KV transmisson line. It is equipped with Germany Deutz diesel engine, Germany Rexroth hydraulic pump, Italian R.R. reducer, AKG radiator, and Wika Hydraulic instrument.

 

Ningbo Dongfang Macinery of Power Co., Ltd. designs and manufactures complete range of hydraulic tensioners for overhead transmission line from 1990's. Ningbo Dongfang is the sole manufacture who can provide whole set of tension stringing equipment and tools for the overhead transmission line and underground cable stringing in China. We designed hydraulic conductor tensioner for overhead transmission line up to 24 tons capacity, the big hydraulic conductor tensioner 4 X 60 KN can be used for big conductors stringing up to 45mm diameter, with 4 independent hydraulic motors for driving four sets of bull wheels.

From 1980's, the Chinese engineering companies started using hydraulic conductor tensioner instead of mechanical friction tensioner on transmission line construction. (It is still used in some area and some countries). First, the hydraulic conductor tensions were used in 500KV transmission line, then 220 KV and 330 KV transmission line. Chinese manufacture started to make hydraulic conductor tensioner from the end of 1980, the production level is almost same as the world leading manufacture now.

Compare to the mechanical friction tensioner, the hydraulic conductor tensioner have following features:

1) The Tension force of hydraulic tensioner can be controlled stepless, the tension force is stable in the stringing.

2) The hydraulic system of Tensioner has over load protection system, the max. tension force of conductor tensioner could be pres-set, this function could protect the conductor and reduce the wear of machine parts. The operation prevent the wear of conductors in the stringing, and reduce the electric power loss caused by corona.

3) The cooling system of hydraulic tensioner is also driven by hydraulic oil, it is more efficient and stable.

4) The modern hydraulic conductor tensioners are equipped with high performance discharge pump and hydraulic motors, for setting up closed hydraulic circuit system. The hydraulic reaction speed is very fast and sensitive. Most of hydraulic tensioners also have pulling functions.

5) The hydraulic system also can be electric controlled include the hydraulic pump and hydraulic valve, the tension procedure could be registered by computer, and remote controlled.

 

Most of Chinese engineering companies are using hydraulic conductor tensioners in their overhead transmission line construction now.
