Temperature maintenance or freeze protection of pipelines and vessels in non-hazardous areas
The junction box for series resistance heating cable SNF is designed for the purpose of connection of heating cables to power network. The junction box could be mounted on a wall of a building or using a bracket directly on a pipe / vessel surface. The box enables connection of SNF cable heating sections to power cable. The junction box is used as part of cable heat trace systems for pipelines and vessels in non-hazardous areas. The junction box design ensures moisture and dust ingress protection IP66 and high corrosion stability. The junction box is available with cable glands for connection of unarmored power and heating cables. The installed terminal blocks ensure fast and safe connection of multicore or single core conductors. The boxes are available with screw clamp terminals as well as with push-in terminals.
