Ningbo Huaxiang Dongfang Macinery of Power Co., Ltd. is known as the leading manufacture of transmission line stringing equipment and tools in China, for supply safe, reliable and competitive products to the world market. During the last 25 years, Ningbo Dongfang became from a local manufacture to the leading manufacture in China. The products of transmission line stringing equipment and tools have been exported to more than 40 countries. The hydraulic conductor puller and hydraulic conductor tensioners are main products of Ningbo Dongfang. From 1998, Ningbo Dongfang started to produce hydraulic conductor puller and hydraulic conductor tensioner with the cooperation of National Power Company in China.
Hydraulic conductor tensioner is used for installation Overhead Transmission Line Conductors, OPGW and earth wire with tension force. The hydraulic conductor tensioner is composed of a few main parts: Hydraulic brake system, Diesel engine, Hydraulic Pump, Hydraulic motor, Bull Wheels, Hydraulic Radiator, Main Frame, etc.
The hydraulic braking force is formed and controlled by hydraulic overflow valve on the tensioner.
The tensioner was developed with the construction of overhead transmission line from 70 years ago. The history of conductor tensioner started from mechanical friction system, then more and more hydraulic tensioners are produced and accepted by engineering people from 1970's. Although there are still some countries are using mechanical or electric tension systems, but most of main manufactures in the world are using hydraulic system for their tensioners.
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.
