Explosion-proof Terminal Box

The explosion-proof terminal box is a specialized enclosure designed to house electrical connections and components in hazardous environments where there is a risk of explosion due to the presence of flammable gases, vapors, dust, or fibers. These boxes are engineered to contain any internal explosion, preventing it from igniting the surrounding atmosphere. The IIC classification denotes environments with the highest risk of explosion due to the presence of gases, vapors, or mists with very low ignition energy, such as hydrogen, acetylene, and carbon disulfide.

Features of IIC Explosion proof Terminal Box

* Cable entry

* Used in chemical, oil refining, oil exploitation, offshore oil platforms, oil tankers, military, and other hazardous areas; Suitable for cable distribution when installing electrical appliances and lamps and especially when installing electrical heat tracing systems and high-power electric heaters on site.

* Beautiful appearance: Aluminum alloy enclosure with stainless steel exposed fasteners.

* Different installation methods such as hanging, embedded, heat tracing bracket installation and different incoming cables such as ordinary rubber and plastic cable, armored cable, and heating cable.
