Its main function is to make the line unobstructed, keep the cable sealed, and ensure the insulation level at the cable joint, so that it can run safely and reliably. If the seal is not good, not only will oil leak cause the oil-impregnated paper to dry up, but also moisture will penetrate into the cable interior, which will reduce the insulation performance.
