  • This product is the FJH type explosion-proof two-way (straight type) junction box, mainly used for connecting electric heating cables in explosion-proof areas (such as factory Zone 1, Zone 2) or humid areas. Its core function is to reliably connect two sections of heating cable to increase the overall length or to meet the connection requirements for heating cables of different power ratings on the same pipeline. The product complies with explosion-proof standards, ensuring safe use in hazardous environments.

  • Applicable in hazardous locations of factory Zone 1 and Zone 2​ where explosive gas mixtures are present.

  • Used for the connection and protection​ of electric heating cables in humid environments.

  • Specific Uses: In electric heat tracing systems for pipelines and tanks in industries such as petroleum, chemical, and natural gas, it is used for extending/connecting heating cables​ or as a transition connection between heating cables of different specifications.

  • Intrinsic Safety Explosion-Proof: Has a defined explosion-proof marking (Ex e II C T6 Gb). When used in conjunction with heating cables of the corresponding protection level, it can be safely operated in specified explosive gas environments.

  • Dedicated Connection Function: Specifically designed for electric heat tracing systems, providing a reliable explosion-proof connection node between heating cables.

  • System Extension Flexibility: Allows for the safe extension of heating cables within the explosion-proof area, or the integration of heating cables with different power ratings, increasing the flexibility of system design.

  • Clear Structure: Straight-through structure with clear installation direction. Comes with a product installation schematic diagram to guide users in correct installation.
