Machine Bolt and Nut Set-manufacture,factory,supplier from China

We keep our packages are strong and safe to be sure customers can get good packages after long-term transportation. 

We calculated the ordered items quantity and give instruction to customers, increasing or reducing some quantity to be sure all items can be loaded in the full container. We won’t waste any sea freight to let some space empty and all items within allowed limit of weight.

Characteristics1) low wear: because of the big bar and short good sized clench conductor, the cord is tough to slide, the wear and tear might be minimum.2) save you loosening: the preformed has preserving elasticity, it make sure it not unfastened in long time;3) good corrosion-resistance characteristics: after antirust processing, the cord ensuring the sturdy corrosion resistance;4) clean set up: no unique equipment, the hand can installation quick and easy in locale, one person can finish.5) installation first-class warranty: no need the special training; it is able to be inspected by using

We clean our workshop on time and keep our workers workings in a clean, comfortable and organized place. 

Features of Transmission Line OPGW Tension SetA. the stress distribution is uniform and there can be no pressure focus factor, that can protect the optical cable well.B. beneath the concept of now not exceeding the lateral compression electricity of the optical cable, it has a greater grip at the optical cable and can resist more tension.C. the grip energy of the optical cable isn't always much less than: 90 5% of the last tensile energy (uts) of the optical cable, that is clearly suitable for the wishes of optical cable erection.

Electricity is the most indispensable energy source in our lives. Without it, our lives will fall into a mess, and it is the high-voltage wires that ensure that the electric energy reaches our living places safely. In the past, when technology was not so advanced, wires were pulled from the sky to every household, so many small counties still have many cables between houses. In cities, more are buried underground, which can be more secure. However, in many heavy industrial areas, high-voltage wires still need to be passed through high-altitude.

With the continuous growth of China's national economy as a whole and the influence of the reform of telecommunications system, the market demand for ADSS power optical cable has increased significantly, reaching 10 million core kilometers in 2001.In the 21st century, there were several situations at that time: (1) Domestic optical cable enterprises were affected by the "bubble" of optical network, and the telecom market shrank, and the supply exceeded demand.

Identification and use of strain clamp specifications: According to the wire, the general strain clamp can be divided into two types, one is the wire strain clamp, and the other is the optical cable strain clamp. Their appearance is very different and can be easily distinguished.　　 The wire tension clamp is also called the bolt-type tension clamp (NLD-1). When in use, the vertical pressure of the U-shaped screw and the friction generated by the wavy slot of the wire clamp are used to fix the wire.

1.1 puncture structure, easy installation, no need to peel insulated wire; 1.2 moment nut, constant puncture pressure, ensure good electrical connection without damaging wire; 1.3 self sealing structure, moisture proof, water proof, corrosion proof, extend The service life of insulated conductors and clamps 1.4 use special contact blade, suitable for copper (aluminum) Butt joint and copper-aluminum transition 1.5 electrical contact resistance is small, contact resistance is less than 1.1 times of resistance of equal length branch wire, dL/T765.1-2001 standard 1.6 speci

The preformed suspension clamp is used for the connection of various wires such as ADSS optical cable and OPGW optical cable in the linear pole tower.

We finished the HDG angle cross arm and arranged shipment in May of 2019 to our customers from Tanzania.
