With the wide application of 10kV SF6 inflatable cabinets, the market's requirements for the convenience and safety of products are constantly improving. The design of the cable room should not only meet the safety distance and convenient installation, but also consider the rated current of the design. Ensure the installation height of the cable with the largest wire diameter. In the long-term operation of the equipment, if the height is insufficient: the insulator of the SF6 inflatable cabinet is easily damaged by the cable plug under the action of stress, resulting in air leakage of the SF6 inflatable cabinet and other problems. High and even lead to the risk of explosion in the cable room. ).

        Our company's 10kV SF6 inflatable ring main unit cable connector is designed to be 745mm high from the bottom of the cabinet (higher than the standard value of 650mm for the State Grid and China Southern Power Grid), and a bracket for fixing the cable is installed at the same time. It not only ensures the convenience of the cable installation, but also eliminates the cable stress, which greatly improves the safety performance of the equipment.
