Explosion-proof tee junction boxes are used for connecting electric heat tracing cables in explosion-proof areas, extending the length of the heat tracing cables, or for applications on the same pipeline requiring different power levels of heat tracing cables and complex configurations like tee lines. The explosion-proof marking is "Exedm IIB T4", and when paired with the heat tracing cables, it is suitable for use in Zones 1 and 2 of factories where explosive gas mixtures are present. The housing is made of high-strength plastic.
