Amid the global trend of smart grid upgrading towards higher intelligence and reliability, drop-out fuses, as core protection equipment for distribution lines and transformers, are entering a critical period of technological iteration. With over 30 years of experience in the high-voltage distribution equipment industry, Wenzhou Shuguang Fuse Co., Ltd. (hereinafter referred to as "Shuguang Fuse") has achieved dual leaps in safety performance and intelligence level in the fields of Porcelain Drop Out Fuses and Outdoor High Voltage Fuses, relying on its accurate grasp of market demands and continuous R&D investment. It provides reliable and innovative product solutions for power grid upgrading and transformation.

As a senior fuse manufacturer in the industry, Shuguang Fuse has always taken material innovation and structural optimization as the core focus of product upgrading. To address the pain points of traditional drop-out fuses, such as high maintenance costs and high operational risks, the company has integrated high-performance insulating materials and precision structural design into the R&D and production of Porcelain Cutouts by drawing on cutting-edge technological concepts. This not only improves the weather resistance and mechanical strength of the products, but also effectively suppresses arc generation by optimizing the layout of arc-extinguishing components, significantly enhancing conductivity efficiency and breaking reliability. Among them, the company's core product RW12 Fuses has achieved a substantial reduction in contact resistance due to its optimized arc-extinguishing structure and spherical contact design. It performs excellently in high-load distribution scenarios and has become a preferred product for many power grid transformation projects.

Intelligent upgrading is another important breakthrough direction in Shuguang Fuse's product innovation. In response to the core demands of smart grids for remote equipment monitoring and fault early warning, the company has integrated multi-dimensional condition monitoring modules into its Drop Out Fuses product series. Through temperature, vibration and other sensors, it collects real-time equipment operation data, and can early warn potential faults such as fuse aging and poor contact with the help of independently developed edge computing algorithms, greatly reducing unplanned power outage time. At the same time, the products adopt a low-power actuator design, which not only adapts to the upgrading and transformation needs of existing power grid equipment, but also provides reliable hardware support for remote control and collaborative operation and maintenance of smart grids, fully meeting the technical requirements of new energy grid connection, UHV construction and other scenarios.

Adaptability to extreme environments is a key indicator to test the quality of fuses, and Shuguang Fuse has also delivered an outstanding performance in this field. Aiming at complex working conditions such as high cold, sand and dust, and high altitude, the company has innovatively adopted a friction guidance mechanism and a dust-proof contact design in its Porcelain Drop Out Fuses products. This design not only ensures the smooth tripping of the fuse tube in a low-temperature environment of -40℃, but also can automatically clean the dust accumulated on the contacts through the movement of the fuse tube, avoiding false fusing problems. Relying on this advantage, the company's products have been successfully applied in special scenarios such as northwest wind power bases and plateau mines, demonstrating excellent environmental adaptability in actual operation and winning high recognition from customers.

A relevant person in charge of Shuguang Fuse stated that with the in-depth transformation of the energy structure, drop-out fuses are evolving from traditional passive protection devices to active intelligent nodes. In the future, the company will continue to focus on the technological innovation of core products such as Drop Out Fuses, further integrate the Internet of Things technology and high-performance materials, and deepen collaborative cooperation with upstream and downstream enterprises in the industrial chain. It will contribute more competitive products to support the global smart grid upgrading and consolidate its leading position in the high-voltage fuse field.
