1. The location of the explosion -proof light line:

Electrical routes should be laid at a position with less danger of explosion or a distance from a distance from a distance.

2. The laying method of explosion -proof light lines:

In the explosive dangerous environment, electrical lines mainly have explosion -proof steel pipe wiring and cable wiring.

3. The isolation seal of the explosion -proof light line:

When laid the voucher of the electrical line, and the protective pipe, cable or steel pipe, when the wall or floor is passed through the areas of different areas of explosive environmental levels, non -combustible materials should be adopted.

4. Selection of wire materials of explosion -proof lamp lines:

Within the scope of explosion hazardous environmental hazardous level, the distribution line should be used by copper -core wires or cables. Multiple copper -core soft lines or multiple copper core cables should be selected in a severe vibration. Aluminum core power cables shall not be used under the coal mines. Within the scope of explosion hazardous environmental hazardous level 2 areas, the power line should adopt an aluminum core wire or cable with an cross -sectional area of 4mm2 and above. The lighting line can use the cross -sectional area of 2.5 mm2. Or above aluminum core wires or cables.
