[0002] With the rapid development of energy storage, charging piles, power electronic transformers and other industries, the demand for product capacity is gradually increasing. On the basis of product standardization design technology, the cabinet interconnection scene between outdoor cabinets is applied more and more. In the traditional cabinet interconnection, the interconnection between the copper bars, cables or electrical devices in the cabinet is arranged through the cable from the bottom of the cabinet. The trench needs to be laid in advance or attached to the bottom of the cabinet. If there is no trench, armored cable needs to be used to enhance the protective ability of the outer skin to avoid damage to the cable by mice and insects. However, compared with ordinary cables, armored cables have large diameter and bending radius, which requires more space in the cabinet and makes the construction more difficult. The length of the cable also increases. With the continuous improvement of current requirements, the diameter and bending radius of the cable increase, especially when wiring from the bottom of the cabinet. The construction is slow, difficult and consumes a lot of resources, which is not conducive to construction and cost reduction.
