The recycling price of such scrap copper cables is 23 yuan per pound. This scrap copper cable is a low-voltage cable yjv22 four-core cable.
I also have to talk about how much it costs to recycle scrap cables. The price per meter is calculated based on the cable model. The prices of different models are definitely different.
How much does one meter of scrap cable cost = the price of copper or aluminum multiplied by the proportion of copper or aluminum produced in one meter of cable.
Cable recycling prices are updated every day!
Electricity originally existed in nature. Later, people gradually studied it and finally were able to produce it themselves.
Electricity is a physical phenomenon produced by stationary or moving charges. In real life, the mechanism of electricity gives many well-known effects, such as lightning, frictional electrification, electrostatic induction, electromagnetic induction, etc.
The electrical energy used in daily life mainly comes from the conversion of other forms of energy, including water energy (hydropower), thermal energy (thermal power), atomic energy (nuclear power), wind energy (wind power), chemical energy ( Batteries) and light energy (photovoltaic cells, solar cells, etc.), etc.
Extended informationCommon power generation methods:
1. Hydropower generation: The basic principle of hydropower generation is to use the water level difference to generate electricity with a hydraulic generator, that is, to use the position of the water to generate electricity. The mechanical energy can be converted into the mechanical energy of the water wheel, and then the mechanical energy is used to drive the generator to obtain electricity. Scientists take advantage of the natural conditions of water level difference, effectively utilize fluid engineering and mechanical physics, and carefully combine them to achieve the highest power generation capacity, so that people can use cheap and pollution-free electricity.
2. Thermal power generation: Thermal power generation refers to a power generation method that uses the heat energy generated when combustible materials (mostly coal in China) are burned and converts it into electrical energy through a power generation device. The main equipment systems of thermal power plants include: fuel supply system, water supply system, steam system, cooling system, electrical system and other auxiliary processing equipment.
3. Nuclear power generation: The core device of nuclear power generation is the nuclear reactor. Nuclear reactors are divided into thermal neutron reactors and fast neutron reactors according to the neutron energy that causes fission.
4. Wind power generation: Converting wind energy into electrical energy is the most basic way of utilizing wind energy. Wind turbines generally consist of components such as a wind wheel, a generator (including devices), a deflector (tail), a tower, a speed limiting safety mechanism, and an energy storage device.
5. Geothermal power generation: Geothermal power generation uses underground thermal energy to generate electricity, which is similar to thermal power generation.
