Rigid Fire-Resistant Cable

This product features a new type of cable with a seamless copper tube sheath on the outer layer, filled with magnesium oxide crystal powder as insulation material, and constructed from a single-strand copper rod conductor. It boasts exceptional properties such as high-temperature resistance, fireproofing, explosion-proof capabilities, and non-combustibility (capable of continuous long-term operation at 250°C, and even short-term performance for up to 30 minutes under extreme conditions of 1000°C). Additionally, it offers high current-carrying capacity, a compact outer diameter, superior mechanical strength, an extended service life, and is resistant to ants and rodent bites. The copper sheath also serves as a protective grounding wire.
