Can the resin that is used in high-voltage resin joint serve as the main insulation

Yes, the resin used in high-voltage resin joints can serve as the main insulation. The resin is specifically designed to provide electrical insulation and withstand high voltage levels. It is applied to protect and insulate the electrical connections, preventing any leakage or short circuits. The resin is capable of withstanding the high electrical stress and providing a reliable insulation barrier.
