Shenhai Explosionssäker
Kunder frågar ofta om den interna kabeldragningen i explosionssäkra distributionslådor. I dag, teamet på Explosionsproof Electrical Equipment Network delar följande riktlinjer:
1. Effektområdet för fördelningsboxen är mellan 7.5 till 10 kilowatt, lämplig för användning av 220-volts fläktar och elverktyg. The configuration of the distribution box should be based on these two requirements.
2. For a three-phase four-wire leakage protection switch, a range between 63A to 100A is appropriate. For 220-volt leakage protection, a 32A switch is suitable. For 220-volt outlets, 10A for two-pin sockets and 16A for three-pin sockets are recommended.
3. Regarding the installation of components, the three-phase four-wire leakage protection switch should be secured using four 4mm bolts and nuts. The 220-volt leakage protection switches and sockets should be mounted on a rail, which is fixed with self-tapping screws.
4. Use 6 till 8 square millimeter single-core copper wire for power lines, in red, gul, and green colors. For 220-volt power supply, använda 2.5 square millimeter single-core copper wire in red and blue. The ground wire should be a 2.5 square millimeter green-yellow striped wire.
5. For ease of maintenance and use, separate 380-volt and 220-volt supplies. That is, directly connect 220 volts at the power inlet. The power inlet should use a three-phase five-wire system, which includes three phase wires, one working neutral wire, and one safety ground wire.
It is hoped that everyone will diligently learn these wiring methods and precautions, adhering strictly to the standards to ensure proper and safe wiring.
