3. Anti twisting braided steel wire rope

Anti twisting steel rope is specially braided from  high strength, high flexible galvanized steel wire. The braided steel strand has high flexibility, complete stability to rotation under tension force. The wire rope is lubricated for long time usage.

It can homogeneously distribute the pressure between the elementary wires. The special rope can increase efficiency during the overhead transmission line stringing work. The rope is packed in steel drum which can be installed directly on the reel winder of puller.

7. SINGLE CONDUCTOR PULLEYS

Application: The single nylon sheave stringing block is used for OPGW or single conductor stringing. The sheaves are all made of high strength MC nylon. All the sheaves are mounted on high strength heavy duty ball bearings. The frame of rollers is made of galvanized steel.

8. U SHAPE BEND RESISTANCE CONNECTOR

Application: The pilot wire connectors are specially designed and made to connect the pilot wire rope, and pulling rope to pass over the conductor pulleys, bull wheels of hydraulic puller or puller-tensioner. It is processed from high strength forged steel, and galvanised. The special profile minimizes the overload on the rope spliced eyes during the passage.

9. Stringing Swivel Joints

Application: It is used to pull conductors. Constructed with ball bearings inside, to eliminate the torque force which stringing conductors. The product can not be used for connection of pilot ropes, because it can not pass through the bull wheels of puller.

The rapid industrialization in the 20th century made electrical transmission lines and grids a critical part of the economic infrastructure in most industrialized nations.

The first three-phase alternating current power transmission at 110 kV took place in 1907, On April 17, 1929 the first 220 kV line in Germany was completed, running from Brauweiler near Cologne. The world's first 380 kV power line was built in Sweden, the 952km Transmission line from Harspranget – Hallsberg in 1952. The first 1000 KV Transmission Line was completed in China in 2009. The strong requirement of high voltage transmission line push the fast development of transmission line tension stringing equipment and tools in China.

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 28 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.
