Product Description

In the current wind power market, the composite materials, because of its unique performance advantages to become the mainstream of wind turbine blades, in order to achieve high-strength and lightweight. The traditional flashing system can not provide complete protection. In the cases of actual lightning damage, the lightning strike can bypass the flashing device and hit the blade, which is very common. The blade, as the most exposed part of the wind turbine, suffered about 15% to 20% of the probability of wind turbine lightning strike, especially with the tip of the blade damaged mostly. Serious lightning strike even led to multiple flasher destroyed. The large maintenance cost and the long downtime, property caused huge economy losses to the wind farms. KINSON’s LSP expanded material is very thin and light, and the openings are uniform with good conductivityt. As an excellent conductive medium, it can conducts electrical current and dissipate static electricity to protect the carbon fiber materials under it. The expanded copper foil/mesh and the expanded aluminum mesh/foil, has been an essential material in the lightning protection on wind blades.

Application

Blade shells, blade tips, carbon de-icing devices, carbon beam.

As in the aviation industry, it is also very strict on the weight and performance requirements in the wind power industry. Drawing lessons from foreign cases, for different blades, we recommend different weights of expanded materials with different openings.

For wind turbine blade, lightning is most likely to hit the leading edge and the tip where the blade static energy is the highest. Usually, a higher density and conductivity material are utilized here. For the root part of the blade, we recommend using lighter LSP materials.

KINSON can customize the production according to the customer's requirements of weight, conductivity, opening and other parameters.

Advantages of KINSON’ LSP materials

Meet specific requirements of high conductivity, which can withstand lightning strikes of many times.

Uniform openings and thickness, resulting in a smooth surface, easier penetration of adhesives, easy dry or wet laying; be a tight, non-delaminating structure after curing and molding.

Easily repaired, resulting in lower maintenance costs and less downtime.

Proven lightning protection technology and solutions used by leading blade manufacturers at home and abroad.

More Applications

Aerospace

Generally speaking, metal aircraft made of aluminum can be used safely for decades, because the metal aircraft's own electrical conductivity is enough to protect the aircraft from lightning strikes, with the development of science and technology, composite materials are widely used in aviation aircraft, when lightning strikes or lightning current flows through the composite structure, it will cause this composite structure embrittlement, delamination or fracture. And the most serious damage to the composite structural parts is usually the highest energy density of the lightning inflow point or out point.

Battery

The electrically active material compromising the electrodes of most modern battery designs are powders and require a mechanical support structure to hold them in place during the manufacturing process. This support structure also functions as a current collector and provides the electrical connection point for the external circuit. In the battery production, the expanded metal foils are coated with active electrode material and then roll to cylinder, which is the main structure of battery core.

Electromagnetic Shielding

The screen net can not only shield electromagnetic radiation interference, but also transmit light, so it is the only available shielding material for observation and display holes. At present, it has been widely used in radar display, computer display terminal, printer, radio, spectrum meter, precision instrument and so on digital and image display window, electronic shelter and electromagnetic shielding of shielding room observation window.

Hydrogen production bipolar plates and fuel cells

The membrane support grids are made of nickel-plated steel and pure nickel, and in different modes as 3Dstructure, flattened and corrugated. The products are characterized by smooth surface, uniform thickness, high electric densitylow resistance, corrosion resistance, uniform and smooth fow field, low maintenance cost and so on, so they are widely used inlarge electrolvzers, KiNSON can produce the products accordina to the reauirements of material. hole. thickness, strand. modeand dimensions.Our team is professional in the electrolyzer units and spare parts, including end load bearing plates, end polar plates, middlepolar plates, bipolar plates, besides welding and electroplating services. We have mature technology and successful projects.

Industrial

Expanded metals, along with our other metal alternatives, is manufactured with no waste and is available in 2D and 3D appearances. It has exceptional corrosion, heat, and impact resistance. The unique properties of lower and higher alloyed grades provide resistance to corrosion in many different environments. Moreover, 2D and 3D appeared can expand the area and carry much more catalysts. The manufacturing process adds rigidity to the original material and the mesh can be annealed to improve its formability. Expanded metal mesh is a versatile and durable one-piece construction that is used for a wide range of applications. Industries we commonly serve include HVAC services, filtration, petrochemical, food service, automotive, acoustics, architecture and more.
