Product Description

Ring network cabinet is a group of electrical transmission and distribution equipment (high voltage switchgear) installed in metal or non-metal insulated cabinet body or made into an assembled spacer type ring network power supply unit, the core part of the load switch and fuse, has the advantages of simple structure, small volume, low price, can improve the power supply parameters and performance and power supply safety. It is widely used in urban residential areas, high-rise buildings, large public buildings, factories and other load center distribution power stations and box substation.

Ring network cabinet is commonly known as the SF6 load switch and SF6 load switch + fuse combination appliance used in ring network line or terminal. SF6 load switch is an excellent load switch experienced by many users in recent years. In addition to the advantages of long electric life, strong breaking force and vacuum load switch, its outstanding advantages are easy to achieve three working positions (on, off and ground), small current (inductance, capacitance) breaking, strong resistance to harsh environmental conditions.

Ring network cabinet is generally divided into air insulation and SF6 insulation. It is used for dividing and closing load current, breaking short circuit current and transformer no-load current, and charging current of overhead line and cable line at a certain distance. It plays a role of control and protection, and is an important switching equipment for ring network power supply and terminal power supply.
