Power Transmission line pole/Tower
Â
1. Based on its shapes, it is generally divided into 5 types: Goblet type, cathead type, cathead type, shaped type and barrel type.
Based on application, it can be divided into: Strain tower, straight line tower, angle tower, transposition tower (tower for transposition of wire phase position), terminal tower and crossing tower, etc.
Â
2. Their structural features are: All kinds of towers are of space truss structures; Bard are mainly composed of single equal angle steel or assembling angle steel; Materials are generally Q235(A3F) and Q345(16Mn); Bars are connected by black bolts with shearing force; Entire tower is composed of angle steels, link plates and bolts; A few components like tower base are assemblies of welded steel plates for convenience of hot galvanizing anti-corrosion, transportation and erection.
3. For steel towers that with height below 60m, shackles are mounted on one of main columns for construction people to climb to work. Our Company is a large scale enterprise specializing in manufacturing of 220KV (330KV) electric power steel tower with advanced manufacturing facility and international top-ranking assembly line.

IPA Presaturated Cleaning Swabs
Presaturated Clean Foam Swabs are pre-wetted with IPA solution, and packaged in a sealed aluminium foil bag. IPA Presaturated Cleaning Swabs are ready to use, time saving, and disposable, they are suitable for less use applications. The foam tip is absorbent, soft and clean, it is a good option to remove oil, ink, and glue. Pre-wetted Cleaning Swabs are ESD safe as IPA solution is apparently electrostatic dissipative. IPA Presaturated Swab is widely used on many applications such as printhead, capping station, transport rollers, keyboard, and many more.
