35KVTRD-YSM inflatable fully insulated ring main switch cabinet

1、 Product Overview: TRD-YSM Inflatable Fully Insulated Ring Network Switchgear is a new generation of small-sized modular switchgear. It has the advantages of compact structure, full insulation, full enclosure, * * life, no maintenance, small space occupation, safety and reliability, and is not affected by public environment. It is suitable for three-phase AC 50HZ, rated voltage 12KV/24KV distribution equipment Widely used in industrial and residential power cable ring main units and power supply terminals. Specially used in small secondary distribution stations, switch stations, industrial and mining enterprises, urban residential areas, airports, railways, tunnels, high-rise buildings and other power systems to receive and distribute electrical energy. 2、 Product features: TRD-YSM-12/24 fully insulated gas filled cabinet uses SF6 gas as arc extinguishing and insulation medium. The switchgear is a fully sealed, fully insulated structure with busbars. The switch and live parts are enclosed in a stainless steel casing. The chamber is filled with SF6 gas at 1.4 bar, with a protection level of IP67; The entire switch device is not affected by external environmental conditions, and can ensure normal operation of the switch even under short-term water immersion and other extreme conditions. The product is maintenance free for life. The switchgear has a complete five prevention interlocking device to prevent personnel injury and operational failures that may be caused by human error. So the inflatable cabinet has a reliable safety pressure relief channel, which can ensure the personal safety of operators even in the * end situation. The switchgear is divided into two types: fixed unit combination and expandable unit combination. Switchgear usually has front incoming and outgoing lines, and can also be installed in different positions to achieve side outgoing lines or side extensions. The cabinet size is easy to install and can be suitable for places with limited space and poor environmental conditions. The switchgear can be equipped with electric mechanism operation, remote and monitoring devices according to different user needs. 3、 Performance indicators: 1.
