Paper wrapped aluminum flat wire

Paper wrapped flat aluminum wire is a winding wire made of oxygen free copper rod or electrical round aluminum rod extruded by a certain specification mold, and then wrapped with insulating paper. It is mainly used for winding transformers, welding machines, electromagnets, or other similar electrical equipment products. 

The electrical bare copper (aluminum) wire produced by extrusion technology is the most ideal material for producing paper wrapped wire. The advantages of paper wrapped wire are due to its extremely high electrical, chemical, and mechanical integrity, as well as good elasticity, flexibility, tear resistance, moisture resistance, and wear resistance. It is also highly resistant to acid and alkali corrosion, and will not be damaged by insects, fungi, and fungi. It can be compatible with all types of varnish, adhesives, transformer liquids, lubricants, and refrigerants. 

In addition, NOMEX paper has high heat resistance, and even at temperatures as high as 220 ℃, it still maintains its original insulation performance, The use of paper wrapped wire transformers can bring many economic, environmental, and safety benefits to customers. Reduce costs, reduce size, and reduce weight by using insulated transformers.

 The temperature rise can be designed to 180 ℃, requiring fewer wires and iron cores. The size can be reduced to reduce weight, thereby reducing infrastructure costs and facilitating installation. A smaller iron core also means less no-load losses; Improving reliability by using paper wrapped wires for transformer windings, which maintain excellent electrical and mechanical properties throughout the entire service life of the transformer. The paper is resistant to shrinkage, compression, elasticity, and aging, and has good thermal shock resistance. Therefore, it can ensure that the transformer coil structure is tight and does not crack. In addition, NOMEX insulation paper is not sensitive to temperature and dust, improving transformer reliability. 

Increase the backup capacity of the paper to withstand high heat temperatures, even when the temperature reaches 220 ℃, it still maintains its original insulation performance. The design of the transformer uses C-class 220 ℃ insulation material as H-class 180 ℃, which can cope with emergency overload loads and unexpected expansion, greatly reducing the backup plan. Good environmental performance, stable chemical properties of insulation materials, safe flame retardant, non-toxic, radiation resistant, and will not release toxic gases even in the event of a fire; It does not react with solvents and is resistant to acid and alkali corrosion. After its service life, it is easy to recycle, resources can be reused, waste can be degraded, and will not cause pollution to the environment.

 It is an environmentally friendly high-tech product.
