Definition and function of three-phase knife switch
The three-phase knife switch, referred to as the knife switch, is an important switching equipment used in the power system. It is an important part of the circuit responsible for opening and closing. The main function is to ensure the safety protection of electrical equipment, personnel, etc. from electric shock when the circuit fails or is repaired.
Two, three phase knife switch material composition
The three-phase knife switch is mainly composed of four parts: operating mechanism, isolating blade, fixed contact and conductive material. Among them, the material types of isolating blade, fixed contact and conductive material are not the same. For example, under normal circumstances, the commonly used materials of the isolating blade are aluminum alloy, steel and copper, etc., the fixed contacts are made of metal materials such as silver cadmium alloy, and the conductive materials are selected as metal materials with good conductive properties.
Third, the material characteristics and advantages and disadvantages of the knife switch
1, isolation blade: Because the isolation blade in the switch operation, need to bear a large mechanical load, so the material requires high strength, high density, good rigidity. Copper material is a commonly used material, with good corrosion resistance, electrical conductivity and thermal conductivity.
2, fixed contact: The material of the fixed contact requires good electrical conductivity, small thermal expansion coefficient, high strength and good wear resistance. In the actual production application, the choice of silver-cadmium alloy as the material of the fixed contact can meet the above requirements.
3, conductive materials: conductive materials need to have good electrical conductivity and mechanical strength. Among them, copper is a commonly used conductive material, which has good electrical conductivity, good corrosion resistance and good processing plasticity.
Based on the above characteristics, the material used in the three-phase knife switch has the characteristics of high strength, good wear resistance, excellent electrical conductivity, etc., so it is widely used in various power systems.
(Conclusion)
This paper briefly describes the definition, function and material composition of the three phase knife switch, and elaborates the characteristics and advantages and disadvantages of the material. The use of copper alloy, silver cadmium alloy and other materials, can meet the switch's strength, electrical conductivity, thermal conductivity and other requirements.

2. Is your company a factory or a trader? What products can be provided?
I mainly produce: torque locking device series, torsion terminal series, floor shard wire clamp series, stainless steel parallel wire clamp series, energy-saving flat wire clamp, aluminum groove series, C-type wire clamp series, aluminum crimping series and other power fittings products.
3. What are the materials of your products? Can do other materials?
Our product material is alloy aluminum. Sometimes, customers want copper preformed materials, we indeed made it before.
However, we still listen to customers if different materials are required.
4. Can your company provide drawings?
Yes, we can. Drawings are a way of confirming the parameters of the products. By providing drawings, we can avoid mistakes. Sometimes, customers sent some pictures with measuring, we engineer can draw a very good technical drawing based on it.
5. Can you provide a Certificate of Origin? Or invoices certified by Embassies?
We have been already recorded and registered in the Commodity Inspection and Quarantine Bureau and the Embassy, so we are qualified to issue certificates of origin and invoices for different countries.
6. When customers show the target price or price from other suppliers, can you agree that?
We are happy when clients give us their advice about the buying price, that means, customers have interested to our company and products, and may in some way, also have trust in us. In this way, it's no doubt to carefully check the target price from customers, listen to their requirements of quality. Give the best solutions.
