It is a junction box with explosion-proof function through various explosion-proof transformations.
Explosion-proof junction box electrical equipment must be connected to the power supply network through wires or cables during use to form a system to complete its use. However, the connecting wire or cable cannot be infinitely long, and there are many places in the connection process that require wire tapping in series and in parallel. This will inevitably cause joints to be exposed and cause accidents. Explosion-proof junction box products are products that are manufactured to solve such problems in order to further ensure safe production. These products include explosion-proof junction box, explosion-proof junction box, explosion-proof box, explosion-proof box, explosion-proof distribution box and other products, and its shell is mainly made of cast aluminum alloy. According to requirements, there are a lot of incoming and outgoing lead-in devices, and the box is equipped with terminals for connecting or tapping. Most of these products are made of explosion-proof or increased safety type, the size of a large or small, the difference is greater, the highest explosion-proof grade up to IIC level.
Explosion-proof junction box technical features
