What to do if the price of copper goes crazy? Aluminum core photovoltaic cable to replace

The introduction of carbon peaking and carbon neutrality goals has accelerated the development of
photovoltaic new energy.
Photovoltaic has lower power generation costs, low site requirements, and faster development
.
In 2020, China's photovoltaic installed capacity will be 48.
2GW, and in 2021, with the decline in wind power installation, photovoltaic installed capacity will continue to increase, will exceed 60GW, and the demand for cables will also increase
sharply.

Photovoltaic power generation cables account for 3% of the total cost of photovoltaic power generation, and in order to further reduce the cost of photovoltaic power generation, cable costs need to be further reduced
.
Domestic cable copper mainly relies on imports, which is greatly affected by foreign copper prices
.

China is a country rich in aluminum and less copper, the cost of aluminum is relatively low, by increasing the section of aluminum conductor, the cost of cables can be greatly reduced under the same current-carrying capacity
.
According to the latest TUV PPP 11029 standard, aluminum core photovoltaic cables have officially entered the market, and photovoltaic host manufacturers have also begun to shift their attention to
aluminum core cables.

According to the requirements of PPP 11029 standard, Far East adopts self-developed 8000 series aluminum alloy conductors, refers to the structure of 5 copper conductors, adopts 5 types of aluminum core conductors, and ensures the bending radius of the cable 6D
.
The weight of the cable is reduced by about 30% at the same ampacity and the cable cost is significantly reduced
.

The launch of aluminum core photovoltaic cables will further reduce the cost of photovoltaics, improve the competitiveness of photovoltaic power generation, and promote the rapid development of
photovoltaic power generation.
