It has excellent power supply reliability, good shock resistance, air tightness, waterproof and other characteristics, convenient construction, low environmental requirements, and maintenance-free. The application prospect of the pre-branch cable is very broad, and at present, it has been rapidly promoted in the domestic market. With the acceleration of various infrastructure construction and real estate development in my country, the market has continuously improved the application types and performance requirements of pre-branch cables, such as the development from the initial ordinary cables to flame-retardant, fire-resistant, halogen-free low-smoke flame-retardant, etc. The required cables are developed from small cross-sections to large cross-sections, from the initial single-core to multi-core and other required cables. At present, the pre-branch cables on the market are all copper core branch cables, and because the cost of aluminum is much lower than that of copper, with the maturity of the aluminum alloy material and its conductor production process, aluminum alloy core pre-branch cables are used instead of copper core pre-branch cables. It is inevitable to reduce investment costs. In addition, aluminum alloy branch cables are lighter in weight and easier to install when they have the same ampacity as copper core branch cables, so they have a market advantage over copper core pre-branch cables.
