Middle-high voltage cable trench structure

A middle-high voltage cable trench structure comprises a main cable trench, and a plurality of auxiliary cable trenches are arranged on one side in the length direction of the main cable trench and are communicated with each other. The middle and high voltage cables are laid in sequence from the main cable trench to the auxiliary cable trench and then to the main cable trench. The device is simple in construction and low in cost, not only can enable the medium-high voltage cable to have abundant length, but also can effectively prevent the medium-high voltage cable from generating an eddy current effect, is safe and reliable in operation, and has important economic benefits and social benefits. 一种中高压电缆沟结构，包括主电缆沟，沿主电缆沟长度方向的一侧设置若干个辅电缆沟且两者之间相互连通；中高压电缆沿主电缆沟到辅电缆沟再到主电缆沟的顺序依次敷设。本实用新型施工简单、造价低廉，既能使中高压电缆存在富裕长度又能够有效避免中高压电缆产生涡流效应，运行安全可靠，具有重要的经济效益和社会效益。
