WIND TURBINE LIGHTNING PROTECTION
For power and energy, the microgrid precision expansion metal provides the necessary electrical characteristics or the required shielding capability. Expanded metal mesh foil plays an important role in the power and renewable energy industries. Considering this, copper is the highest rated heat conductor and conductor in engineering metals. In terms of volume and weight parameters, the power system using copper and aluminum has the highest efficiency and transmits energy. Our continuously optimized microgrid design has been improving the shielding, conductivity and energy transmission characteristics of products.
Lightning of composite structure
Composite materials are more and more used in the structure of various new products. However, how to protect these structures from lightning strikes and compound attacks has become a very important issue.
Compared with metal, composite structures are more vulnerable to lightning strikes. For example, carbon composite materials may be seriously damaged due to the current caused by lightning strikes without proper channels. At present, expanded copper and aluminum have been developed and proved to protect various composite structures including carbon composites when applied to the outer layer of composite materials.
Lightning protection of wind turbine
Wind turbines have become one of the main lightning targets due to their height. Blade is the most expensive part of wind turbine. The longer the blade, the greater the risk of lightning stroke.
When being struck by lightning, unprotected wind blades will generate electric arc from the contact point to the root of the structure through the conductive parts. The temperature of the parts may exceed 35000 ° C and may cause local explosion of the blades. Data show that the size of wind turbines is increasing. Micromesh lsptm can be used to protect these composite structures from lightning strikes and ensure the normal function of components.
Micromesh LSPTM lightning net is made of copper foil or aluminum foil, which is cut and stretched (expanded) into a single, uniform and precise non-woven structure. The manufacturing process will strictly control the performance requirements of the product in terms of weight, conductivity and porosity. This design provides greater conductivity and smoother surface than the woven mesh, while ensuring the formability and adhesion of the composite structure.
