Cost-Effective and Reliable: Compared to copper cables with equivalent conductivity, the aluminum alloy conductor significantly reduces material costs, is lighter in weight, and facilitates transportation and installation.
Strong Mechanical Performance: The double steel tape armor structure effectively resists external pressure, impact, and rodent bites, making it particularly suitable for applications requiring mechanical protection, such as direct burial and conduit installation.
Safe and Flame Retardant: Possesses Class C flame retardancy (bunched cable test), combined with low-smoke zero-halogen sheath material, it can delay flame spread and reduce the generation of toxic smoke during a fire, enhancing safety in public spaces.
Stable Connection: The conductor undergoes special annealing and surface treatment, providing strong oxidation resistance. When used with dedicated connectors, it effectively addresses issues of contact resistance and electrochemical corrosion at joints.
