Detailed Description of Equipment/Material Technical Performance

1. LongAo Company's products feature the following characteristics:

1.1 Excellent product structure and appearance design

1.2 Good process control ensures product quality.

1.3 Multiple trials and impressive operational performance have proven the reliability of the product:

2. Our company uses fluoro-silicone rubber material, which is heat-pressed and shaped to produce the domestically developed fluoro-silicone rubber antifouling skirt. It is categorized into "antifouling skirt for DC suspended porcelain (glass) insulators" and "piling-type insulator antifouling skirt," collectively referred to as the antifouling skirt. It is bonded to the top of the original porcelain or glass skirt using a specialized adhesive (room-temperature vulcanized fluoro-silicone rubber), forming a composite insulator. By adjusting the number of bonding strips, it meets the requirements for increasing the creepage distance of suspended insulators and high-voltage electrical equipment. This product effectively enhances the "flashover" electricity in heavily polluted areas. It boasts excellent corrosion resistance, aging resistance, rain flash resistance, hydrophobicity, and self-cleaning capabilities, while being lightweight and easy to install on-site.

3. Application Range of the Climbing Skirt:

3.1 Rainproof and anti-arc equipment for DC or AC power distribution, especially for equipment with an umbrella distance less than 70mm, it is recommended to use an increased climbing skirt as much as possible.

3.2 When the creepage distance of transmission and transformation equipment in contaminated areas no longer meets operational requirements, an increased creepage skirt is used as a remedial measure for adjusting the creepage.

3.3 In areas with severe contamination and insufficient climbing distance for transformer and distribution equipment, a combination of climbing skirts and anti-pollution flashover coatings can be used for adjustment.

4. Selection of climbing skirt:

4.1 Structure: The climbing skirt is made of fluoro-silicone rubber material, formed through high-temperature molding and pressing. It is installed on top of the ceramic or glass skirt, fitting the surface structure of the original part.

4.2 Size (Increased Creepage skirt for支柱insulators, sleeving) The thickness of the increased creepage skirt is 3.5mm-4.5mm based on the size of the umbrella wire, with the umbrella blades extending 40-50mm beyond the porcelain or glass skirt. Too small a size does not achieve the increased creepage and rain flash prevention effects; too large a size can easily cause the skirt to collapse, resulting in an uneven shape that affects both aesthetics and functionality.

Description of Technical Advantages of the New Type套装 Umbrella Skirt

1. The new type of套装辅助伞裙, based on the existing traditional climbing auxiliary umbrellas (including sheet and enveloping types), has been scientifically redesigned for better structure. It offers improved rain, ice, and dirt flash resistance, significantly enhancing the operational safety and reliability of transmission and transformation equipment. 2. The top surface of the new type of套装伞裙 is flat and smooth, while the bottom surface features a set of transverse protrusions and a set of longitudinal protrusions, forming a grid-like structure through interlacing. This uneven grid structure increases rigidity and effectively prevents rain from being carried to the insulator surface by gravity and wind, offering excellent waterproofing performance.

3. The lower ring of the new type套装式 umbrella skirt is connected to the lower rubber of the insulator porcelain skirt, and it is tightly fitted through a constricted arc design, eliminating the need for filling with adhesive in the residual air gap of the traditional enveloping umbrella skirt, which has the defect of difficult-to-fill dense adhesive due to its viscosity. The new type套装式 umbrella skirt can achieve a firm installation without the need for a cylindrical section, thus avoiding the problem of loose fit caused by dimensional deviations of the porcelain insulator cylindrical section, and eliminating the弊端 of often occurring water rings.

4. The new set-style umbrella skirt employs an innovative 360°+ industrial design technique, creating a monolithic interlocking pattern at the openings of the circular structure. This pattern, formed by the interlocking of protrusions and grooves, results in an overlapping sealed structure, facilitating construction and installation, and further enhancing the skirt's sealing effectiveness. 5. The new set-style umbrella skirt, once installed, presents a neat and aesthetically pleasing shape with strong wind load deformation resistance, fully meeting and exceeding the deformation resistance requirements specified in standards such as DL/T1469-2015 and Q/GDW10673-2016. 6. Tests under the same rainfall and conductivity conditions with porcelain columns or hollow insulators show that using the new set-style umbrella skirt can raise the rain flashover voltage by up to 85% compared to not using it, thereby enhancing the equipment's anti-pollution flashover capabilities.
