Sealed Connectors

Seals are provided in conduit or cable systems to prevent the passage of gases, vapours, or flames from one portion of the electrical installation to another through the system. Passage of gases, vapours, or flames through mineral-insulated cable is inherently prevented by construction of the cable, but sealing compound is used in cable glands to exclude moisture and other fluids from the cable insulation, and is required to be of a type approved for the conditions of use. The conduit is sealed by using an EYS seal fitting and pouring it. One this EYS is poured it can’t be disassembled to make changes. The sealing connectors are designed in such a way that even after kneating or pouring the sealing compound the wires can still be disassembled to make changes. There are two type of sealing compounds: one is two part putty and one is two part liquid. Putty is recommended for all the general purpose cables and liquid compound recommended for shielded cables.
