2 Product advantages and core technologies
The core advantage of Liangsheng fuses lies in their high-quality materials and advanced technology. In terms of materials, Liangsheng uses copper alloy with excellent conductivity, oxidation resistance, and high temperature resistance as the main material. This material can ensure that the fuse can withstand high current shocks and is not prone to short circuits and melting. In terms of technology, the company has introduced automated production lines, greatly improving product processing accuracy and production efficiency, ensuring consistency and stability of product quality. This strict control over materials and processes has enabled Liangsheng fuses to lead most market competitors in terms of basic performance.
Liangsheng fuses exhibit excellent protection performance and response speed. The product has a high transient response speed and precise protection characteristics, which can quickly cut off the current when electrical faults occur, effectively preventing electrical overload, short circuit and other faults, providing reliable protection for personal and property safety. Taking Liangsheng's glass fuse tube (quick break type) as an example, it adopts a quick break design, which can quickly cut off in case of circuit failure, avoiding wider damage. This fast response characteristic is particularly prominent in situations that require high circuit protection, such as data centers, telecommunications base stations, power grid facilities, etc.
The advantages of Liangsheng fuses can be summarized as follows:
Materials Science: Using special copper alloy materials to provide excellent conductivity, oxidation resistance, and high temperature resistance, ensuring the stability of the product under high current impact
Precision control: Ensure product processing accuracy through automated production lines, reduce quality fluctuations caused by human factors, and enhance product consistency and reliability
Response mechanism: With high transient response speed, it can cut off fault current in milliseconds to prevent equipment damage and safety accidents
Environmental characteristics: All products comply with RoHS and REACH environmental requirements, do not contain harmful substances, and meet international environmental standards
Temperature adaptability: The working temperature range is wide up to 55 ℃~+125 ℃, which can adapt to various harsh environmental conditions and meet the needs of use
3 Wide Application Fields and Product Diversity
Liangsheng fuse products have a wide range of applications, covering multiple fields such as industry, automotive, air conditioning, electricity, petroleum, metallurgy, etc., and can meet the safety protection needs of different industries. Whether it is small household appliances or large industrial equipment, Liangsheng fuses can provide precise power protection and safety assurance. This wide range of applications reflects the strong adaptability and reliability of Liangsheng products, and also proves that their technical solutions can meet the circuit protection needs in different scenarios.

The advantage of glass fuse tubes lies in their transparent design, which allows users to directly observe the internal fuse status without the need for additional detection tools. They also have fast response characteristics and cost advantages, with a unit price usually only a few cents to a few yuan. However, glass fuses also have the disadvantage of weak impact resistance, so they are not suitable for high-power industrial equipment.
For high-voltage application scenarios, Liangsheng has developed high-voltage ceramic tube fuses (quick break type), which use special ceramic materials to quickly break and cut off excessive currents in a short period of time, effectively protecting circuit safety. Its model is 5HV, size is Φ 5.2 × 20mm, and it has passed multiple international certifications such as UL/CHUL/TUV, proving that the quality and safety of the product meet strict international standards.
