Explosion-proof distribution boxes are distribution systems that
comprise flameproof (Exd) enclosure, increased safety busbar
boxes and terminal boxes. The surface of explosion-proof
distribution boxes are sprayed epoxy resin powder, therefore they
can satisfy the requirements of anti-corrosion in chemical,
petrochemical and sea industries.

The group of explosion-proof distribution boxes are ⅡB or ⅡC.
The explosion-proof distribution boxes are used for distribution
and overhauling of single phase illumination and 3-phase power
system in the circuits of AC 50Hz, 220/380V. Different circuit
distribution systems may be combined according to the
requirements. Besides the standard combinations, the explosion-
proof distribution boxes may be designed as user's special
requirements.
