  • Technical area
  • The present disclosure relates generally to cable gland connectors and, more particularly, to systems, methods, and devices for a dowel for sealing a cable in a cable gland assembly.
  • background
  • Cable seal assemblies are used to terminate cables in hazardous and non-hazardous environments. Typical cable seal assemblies provide a seal around the conductors of the cable, mechanical retention of the cable therein, passage of current through the termination of the cable, and sealing against the environment on the outer jacket of the cable. To seal the conductors in a seal chamber of the cable gland assembly, a sealant is generally used to seal the individual conductors. In general, the sealant is used in conjunction with a damming auxiliary material to prevent the sealant from flowing out of the seal chamber. Conventional damming materials include fibrous materials wherein the cable gland assembly must be disassembled to incorporate the fiber materials. Furthermore, a large volume of these damper materials is generally required to contain the material therein. Accordingly, the use of a fiber damper material is time consuming and labor intensive for a user during assembly. Cable seal assemblies are available which employ a rubber seal instead of a fiber damper material. However, these rubber seals are generally subject to limitations in their performance.
