Increased safety explosion-proof junction box and explosion-proof junction boxDifference in appearance: Taking the same size 300 * 300 explosion-proof junction box (increased safety type and explosion-proof type) as an example, distinguish the differences in appearance between the two types of explosion-proof junction boxes.

Generally speaking, explosion-proof junction boxes have explosion-proof surfaces, namely flanges on all four sides. The increased safety explosion-proof junction box is not available. So the explosion-proof effect of explosion-proof junction boxes is slightly higher than that of increased safety explosion-proof junction boxes. There is a gap between the upper and lower cover flanges, which may result in explosive gas mixtures inside due to the breathing and gas permeation effects of electrical equipment. When it explodes, the shell can withstand the internal explosion pressure without damage, and the explosion-proof surface of the shell, namely the flange gap, can cool the flame, reduce the flame propagation speed or terminate the acceleration chain, so that the flame or dangerous flame products cannot penetrate the explosion-proof gap and ignite the external explosive environment, thereby achieving the purpose of explosion-proof. In contrast, the increased safety explosion-proof junction box has no flange gap due to the lack of explosion-proof surface, which results in slightly inferior performance in cooling explosive flames and reducing flame propagation speed. But the increased safety explosion-proof junction box also has its advantages. Its protection level is generally slightly higher than that of explosion-proof junction boxes, that is, its performance in terms of waterproofing and dust prevention is higher than that of explosion-proof junction boxes. So generally speaking, it is more suitable for outdoor use. Because there are milling grooves around the cover plate, an encrypted sealing ring can be added. In this way, both increased safety explosion-proof junction boxes and explosion-proof junction boxes have their own advantages and disadvantages. Please order according to your needs when purchasing.
