In extreme scenarios like hydrogen leakage risks in chemical plants, frequent short circuits in PV power plants due to heavy rain, and salt spray corrosion of coastal equipment, the explosion-proof cast aluminum junction box with IP66 waterproof + EXd IIC T6 explosion-proof dual certification has become a key safeguard for industrial equipment safety. This article deeply dissects 3 core technologies of Bsumwell’s product: One-piece die-cast aluminum molding (impact-resistant IK08, 1000+ hours salt spray test without corrosion); Triple-sealing system (EPDM rubber seals resistant to -40℃~120℃, IP66 waterproof pass rate 98.7%); Rigorous EXd certification testing (100 spark ignition tests with zero failure, surface temperature ≤85℃ meeting T6 class).
