What are the main functions of Nylon Cable Gland?

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