1. The conductive circuit of the DFW Low-Voltage Cable Branch Box uses TU1 oxygen-free copper with a copper content ≥99.97%, ensuring a stable contact resistance below 0.35μΩ.
2. The box body is made of ZAM aluminum-zinc-magnesium steel plate with a base material thickness of 2.0mm and a plating weight of 180g/m². After 3000 hours of neutral salt spray testing, only ≤2mm single-sided scratch corrosion was observed.
3. The internal insulation components of the DFW cable branch box use glass fiber reinforced polyester material with a relative tracking index (CTI) ≥600V, allowing for safe operation in polluted environments.
