Low-voltage electrical appliances "fight" Which companies will "fire"?

Polaris Smart Grid Online News: In recent years, China's low-voltage electrical appliance market has entered a high-growth era. Foreign capital, state-owned enterprises, and private enterprises have started to conquer cities and seize market share. The first-tier cities across the country have been slowly developing under the shadow of saturation of demand and policy pressures. If you want to successfully occupy a place in their own development in this extremely competitive environment, they will definitely not do without certain strength and correct market strategies. In the "big battle" in the low-voltage electrical market, which companies are already ready to move and are ready to start to seize the market?

Brief description of electrical contact materials

Brief description of electrical contact materials 1. Electrical contact materials can be divided into the following categories according to the purpose of use: (1) Silver and silver alloy electrical contacts are used for high conductivity and weak current (low-energy circuits) occasions. (2) Platinum and palladium alloy electrical contacts are used for corrosion resistance, oxidation resistance, and weak current applications. (3) Ag-W, Ag-CdO, Ag-Ni, Ag-SnO and other silver-based alloy material electrical contacts are used for arc-resistant, high-conductivity, and low-load occasions. (4) Ag-Cu, palladium, and gold-based multi-element precious metal alloy electrical contacts are used for sliding contacts with wear resistance and low contact resistance.

Contact lubricant working principle and actual use effect

Contact lubricant working principle and actual use effect The electrical contact of an electrical switch is one of the important parts of the electrical contact system. Through the analysis of the contact failure factors and failure mechanism, the article discusses in detail the improvement effect and reliability of the electrical contact point by the new technology of contact protection and lubrication. The mechanism is improved, and the principle of selection and use of contact lubricants is proposed at the same time.

The meaning of quoting silver contacts

Both silver contacts and fine-grained silver tools have extremely strong thermal and electrical conductivity, good welding function, low and constant contact resistance, crystalline silver has a small amount of nickel in the silver, which greatly refines the grains of the data structure. Under the premise of almost the same contact resistance, its mechanical strength and temperature resistance are higher than silver. Silver contacts have the highest electrical conductivity and thermal conductivity, and have very low contact resistance, easy to process and easy to weld.
