With the rapid growth of industries such as petroleum, chemical manufacturing, military production, construction, and mining, explosion-proof distribution boxes have become increasingly essential in various settings including industrial operations, storage facilities, and emergency response scenarios. Ensuring the safety of these devices is crucial, especially in environments where explosive gas mixtures may be present. Since explosion-proof distribution boxes can generate sparks during operation, their exposure to flammable gases could lead to catastrophic explosions, posing a serious threat to human lives, national property, and public safety. As one of the most commonly used lighting systems, their explosion-proof technology has long been a subject of significant concern and continuous improvement.
**First, the installation path requirements for the circuit of an explosion-proof distribution box:**
(1) The main line of the distribution box should follow the shortest possible route, taking into account the terrain and topography to reduce costs and complexity.
(2) Minimize interference with farmland and avoid areas prone to geological risks like depressions, erosion, subsidence, and unstable slopes. Also, avoid locations that are easily accessible to vehicles.
(3) Stay away from areas where hazardous materials such as explosives or flammable substances are stored or produced.
(4) Whenever possible, install the circuit in locations that are easy to access for maintenance and future expansion.
(5) During route selection, consider the significance of nearby buildings and take into account urban development plans and power grid strategies. Ensure there is enough space left for future growth.
**Second, the explosion-proof distribution box circuit should avoid the following areas:**
(1) Areas designated as national memorial sites or historical landmarks.
(2) Residential yards or regions with dense tree cover.
(3) Zones prone to flash floods, frequent flooding, mountainous regions, lakes, or areas with potential geological instability.
(4) Locations with large storage spaces for flammable or hazardous materials, or areas with high levels of corrosive gases, liquids, or contamination.
**Third, the explosion-proof dual emergency lights should avoid the following locations:**
(1) Places that obstruct traffic or visibility.
(2) Slopes adjacent to railway lines or roadbeds.
(3) Areas with underground utilities such as pipes, channels, power cables, or communication lines.
(4) Near building entrances, tunnel exits, or places where vehicle collisions are likely.
(5) Proximity to riverbanks, sandy areas, wetlands, or spring zones during certain seasons.
**Fourth, pole height and depth requirements:**
(1) The height of the pole must be determined based on the geographic location, depth of the installation, the arc of the box, and the vertical clearance from the ground to the conductor. These factors should be calculated using standard electrical safety formulas to ensure compliance with safety regulations.
