This invention relates to the field of transformer technology, specifically a transformer system for high-energy conversion in smart grids. The system includes a bushing body, terminals, an oil conservator, skirts, equalizing rings, and a junction box. When the conductive posts approach each other, they clamp the cable core. Then, the operator manually rotates a push rod, which rotates at the sealing plate. Simultaneously, the mounting block and the two conductive posts rotate synchronously. During this process, the two conductive posts clamp the cable core, causing it to bend. The cable core wraps around the two conductive posts, thus securing the cable. Because the cable is wrapped around and clamped by the two conductive posts, the cable fixation effect is better, avoiding the problem of uneven bolt stress and loosening between the bolt and the terminal block, which is common in existing systems where the cable transmits lateral or longitudinal tension to the bolt connection.
