防爆箱線路應當在爆炸危險性較小或距離釋放源較遠的位置。電氣線路宜沿有爆炸危險的建筑物的外墻敷設；當爆炸危險氣體或蒸氣比空氣重時，電氣線路應在高處敷設，電纜則直接埋地敷設或電纜溝充砂敷設；當爆炸危險氣體或蒸氣比空氣輕時，電氣線路宜敷設在低處，電纜則采取電纜溝敷設。10kV及 10kV以下的架空線路不得跨越爆炸危險環境；當架空線路與爆炸危險環境鄰近時，其間距離不得小于桿塔高度的1．5倍。
配線方式和接線方式。爆炸危險環境主要采用防爆鋼管配線和電纜配線。盡量采用厚壁管，有的可能要做打壓試驗
Explosion proof box line should be in the explosion risk of smaller or more distant from the release of the location of the source. Electrical wiring should be laid along the wall of dangerous buildings; when the explosive gas or vapor is heavier than air, electrical wiring should be in high laying, cable directly buried or cable trench filling sand laying; when the explosive gas or vapor is lighter than air, the electrical lines should be laid in cable is low, take the cable trench laying. Overhead lines 10kV and below 10kV shall not exceed the explosive environment; when the overhead line and explosion hazardous environment nearby, at a distance of not less than 1.5 times the height of the tower.
Wiring mode and connection mode. The explosion hazard environment is mainly used in the explosion proof steel pipe and cable wiring. As far as possible the use of thick walled tube, and some may want to do the pressure test
