A fuse is an electrical component that uses a metal conductor as a melt to be connected in series in a circuit. When an overload or short-circuit current passes through the melt, it fuses due to its own heat, thereby breaking the circuit and protecting electrical equipment and the power grid. The melt Side Composite Strip of Fuse is the key element to control the fusing characteristics, and the Fuse Melt Strip material, size and shape determine the fusing characteristics. Fuse Melting Strip materials are divided into two types: low melting point and high melting point. Low melting point materials such as lead and lead alloys have a low melting point and are easy to fuse. Due to their large resistivity, the cross-sectional size of the Silver Strip for Fuse Core is larger, and more metal vapors are generated during fuse. It is only suitable for fuse with low breaking capacity. Device. High melting point materials such as copper and silver have high melting points and are not easy to fuse, but due to their low resistivity, at a certain resistance, the required cross-sectional area is small and the metal vapor generated during fuse is less, which is beneficial to extinguishing the arc and is suitable for For fuses with high breaking capacity.
Pure Silver melt has a good ability to break strong short-circuit currents, and silver has stable chemical properties, excellent oxidation resistance and corrosion resistance. The resistance value is not easy to change during use, and the melting point is constant, which is beneficial to maintain the stability of the circuit. Performance and safety are the key materials for high-current, high-reliability fuses. However, due to the high price of silver melt, the cost of using silver melt is high.The use of silver or silver alloy in the fuse protection part of the fuse can ensure that the resistance value of the fuse protection part of the Fuse Silver Melting Strip is not easy to change when the strong short-circuit current is interrupted, and the melting point is constant, which is beneficial to maintain the stability and safety of the circuit The characteristic of sex, guarantees the fuse characteristic that the fuse itself should have, and does not affect the safety of electrical appliances and circuits.
Fuse Link Melt materials are divided into two types: low melting point and high melting point. Low melting point materials such as lead and lead alloys have a low melting point and are easy to fuse. Due to their large resistivity, the cross-sectional size of the melt is larger, and more metal vapors are generated during fuse. It is only suitable for fuse with low breaking capacity. Device. High melting point Fuse Melt Strip materials such as copper and silver have high melting points and are not easy to fuse, but due to their low resistivity, they can be made into a smaller cross-sectional size than low melting point melts, and produce less metal vapor during fuse, which is suitable for high breaking Capable fuse. The shape of the Side Composite Strip of Fuse is divided into two types: filament and ribbon. Changing the shape of the variable cross-section can significantly change the fusing characteristics of the fuse. The fuse has a variety of different fusing characteristic curves, which can be adapted to the needs of different types of protection objects.
Silver Inlay and Precious Metal Clad Characteristics:
1-Offer flexibility of material design,being able to product the electrical contact with high mechanical and electrical contact characteristics ;
2-Save precious metal materials with low prices, as precious metal is only used at electrical contact spots;
3-Bimetallic Strip Metals is suitable for continuous automatically manufacture .It does not need other manufacture process ,such as welding or soldering after its formation .Composite Strip Stamping Parts simplifies manufacturing process of electrical parts with high productivity and low cost and raises the assembly precision credibility of electrical component;
4-Precious Metal Composite Strip Stamping is produced by sintering extrusion process, with a density of up to 99.9%. The second component of the silver base is fibrous, which greatly improves the mechanical strength of the wire and improves the Noble Metal Composite Strip resistance to welding, arc burn resistance and mechanical wear resistance;
5-The chemical coating method, co-deposition method and pre-oxidation process are used to make the material's grain refinement, uniform organization, and no segregation in the microstructure, eliminate oxide barren areas, and produce wires with excellent electrical properties.
Precious Clad Metal is a new technical material, based on different industry needs, formed by advanced indoor temperature composite technology or Hot Composite Technique; Silver Inlay and Precious Metal Clad is rolled with different characteristic material strips composite alloy material and base material strip. Their alloy and base material characteristic are well preserved, and the Mid Inlay Clad Metal compound characteristic are very good, esp. The Silver Copper Alloy Strip electrical character and its wearability are much better than single precious metal contact material (such as gold and silver ) . Beside, It is a saving of precious metal, keeping low cost and consistency of social development.
