How does cable sealing end works in a substation?

Cable sealing ends in a substation are designed to terminate and protect electrical cables, ensuring safe and reliable connections. They provide insulation, mechanical support, and environmental protection against moisture, dust, and other contaminants. Typically, these sealing ends incorporate materials such as rubber or silicone to maintain the integrity of the cable and prevent electrical leakage. Additionally, they help to manage thermal expansion and contraction, contributing to the overall longevity of the electrical system.
