As we all know, an explosion-proof junction box is a connection device with explosion-proof and sealing properties for line laying. From the appearance, the explosion-proof junction box is a closed box. When the cable passes through, the cable enters and exits through the lock nut, which effectively avoids the sparking phenomenon in the connection. The shell is generally made of aluminum alloy. In order to make it have better fire resistance and corrosion resistance, aluminum alloy is usually sprayed on its surface.

The explosion-proof junction box consists of a cover, housing, terminal block, diodes, connecting wires, and connectors. The shell must have strong anti-aging and anti-ultraviolet capabilities to meet the requirements of harsh outdoor environments, and the self-locking function makes the connection more convenient and firm. The terminals must be installed firmly, and the busbars must have good solderability. The connectors and cables have good insulation performance, and the male and female plugs have a self-locking function, which makes the solar panel and electrical connection more convenient and reliable.
Explosion-proof junction box performance characteristics. 1. The explosion-proof grade can be used safely in various flammable and explosive dangerous places. High-intensity gas discharge lamps are used as light sources, with high luminous efficiency and long lifespan, with an average lifespan of more than 10,000 hours. Optimized transparent components, soft, uniform light, and no ghosting, effectively avoid the operator's eye discomfort and fatigue.
2. The shell of the explosion-proof junction box is made of light alloy material and is treated by high-tech spraying, which is wear-resistant, corrosion-resistant, waterproof, dust-proof, and long-term use. Exquisite structural design, and good heat dissipation performance, effectively reduces the temperature of the lamp and increase the service life of the lamp. Good electromagnetic compatibility, no interference to the surrounding environment. Light weight, small size, compact structure, and easy operation.
Through the above introduction and analysis of the Features and functions of explosion-proof junction boxes, hope it helps you.
