Copper Wire Generator Is Better, or Aluminum Generator
Is it better to buy all
copper wire generator or aluminum wire generator? Starlight Power recommends
all copper wire generator, why? Our ideas as follow:
1. All copper generators
are more durable
The resistance of
aluminum is larger than that of copper, and the heat generated in the use
process is higher, so it is easy to burn the generator. Moreover, the welding
of aluminum and copper can not be naturally integrated, and the connection
point of power line is easy to be burned out, which leads to the whole life of
aluminum wire motor water pump far lower than that of pure copper wire
generator water pump.
2.All copper wire
generator is more energy-saving
The resistance of the
circuit component is in direct proportion to the heating value, and the heating
value is high when the resistance is high. All copper wire has smaller
resistance than aluminum wire, also low heating, smooth current, no waste of
heat, more energy saving.
3.All copper wire generator
is quieter
For every 3 dB increase
in noise, the noise energy will be doubled. The noise of aluminum wire
generator is 7 dB higher than that of copper wire generator, so the noise of
aluminum wire generator is more than twice that of copper wire generator.
In fact, the movement of
the generator is mainly used for conducting electricity, and the conductivity
of metal materials is relatively good. Let's look at the reference value of
metal conductivity:
The conductivity of
copper wire in the motor is 58.13%, aluminum wire is 35.33%. From these values
we can conclude that copper are more effective for conducting electricity. So
in the selection of generator, Starlight Power recommends that you choose all
copper generator.
The stator coil used to
be all copper wire, but with the improvement of wire making technology,
copper-clad aluminum core wire appeared. Different from the copper-clad
aluminum wire, the copper-clad aluminum core wire is made of a special mold,
and the copper layer is much thicker than the copper plating. There is not much
difference in the performance of generator stator coil with copper clad
aluminum core wire, but the service life is much shorter than that of all
copper stator coil.
Because the material of
generator coil is different, price of diesel generator set will be different.
As a standby power supply genset, we recommend customer to choose all copper
wire generator. When we buy diesel generator set, we should pay attention.
Buying all copper wire generator is better than aluminum wire at the same
price.
How to identify copper
wire generator and aluminum wire generator?
The direct way is to
dismantle the stator coil of the generator and scrape the insulating paint on
the surface of the enameled wire with a blade: the purple red one is copper,
and the silver white one is aluminum wire. After the test, we should cover insulating
paint on it to strengthen the insulation. If you are professional, you can
identify from the difference between resistance and power reduction when
generating electricity.
Starlight Power has two factories in Jiangsu China, one for assembling diesel generator set, one is for producing generator(our own brand Starlight). The coil material of our generator is all copper wire, every parts is made by our factory. And all of our diesel generator sets are with all copper wire generator.
