Explosion environment - Flame-proof connection mode of cable incoming wire
◣ Internal terminal wiring : All lead-in wires are stripped 5mm and directly connected or connected to u-terminal after tin plating.
◣ Threading requirements : Separate into metal pipe (galvanized pipe) ,Do not enter the same tube with power line, lighting line and ac line.
◣ Cable: Use control cable such as KW-3×x1.5,or watertight cable such as JHS-3×1.5 (depends on the environment)
◣ Joint processing: All joints should be pressed and sealed with insulation sleeve to prevent short circuit, leakage and water immersion to meet the requirement of flameproof。
