Starlight generator

There are many brands of generators on the market. Because the materials are different, the price difference of generators is very large. When customers choose   diesel generator sets   as backup power, should choose full copper brushless generator, some bad manufacturers use semi-copper semi-aluminum or aluminum wire generators to directly sell to the customer. Before purchasing, the customer must ask supplier the material of the generator. Why should we choose a full copper brushless generator? Briefly, the movement of the generator is mainly used for electrical conduction, and the conductivity of the metal material is better. Let's take a look at the reference value of metal conductivity: Silver: 100%; copper: 99%; gold: 76%; iron 74% From these values we can conclude that silver and copper are more suitable for electrical conduction. But the price of silver is relatively high, so copper is the perfect movement for the generator. Therefore, in selecting the alt...
