Product Overview:
TG-12 (V, C, F) 630-25 fully enclosed and insulated ring main switch cabinet is a modular unit mode that can be combined according to different purposes: it is divided into two categories: fixed unit combination and expandable unit, meeting the flexible use needs of various substations for compact switch cabinets.
The TG-12 (V, C, F)/630-25 fully enclosed and insulated ring main switch cabinet is a completely sealed system, with all live parts and switches enclosed in a stainless steel casing. The entire switch device is not affected by external environmental conditions, ensuring operational reliability and personal safety, and achieving maintenance free operation. By selecting expandable busbars, any combination can achieve full modularity. The expansion of busbar safety insulation and shielding ensures high reliability and safety. TG-12 (V, C, F) 630-25 fully enclosed and insulated ring main switch cabinet can also provide TV based automation solutions; The concept of intelligent switches has been formed, and the on-site installation and debugging workload has been minimized.
TG-12 (V, C, F)/630-25 fully enclosed and insulated ring main switchgear is divided into non expandable standard configuration and expandable standard configuration. Due to its combination of full modules and half modules, as well as its own scalability, it has extremely special flexibility.
TG-12 (V, C, F)/630-25 fully enclosed and insulated ring main switchgear shall comply with GB standards.
The design lifespan for operation under indoor conditions (20 ¡ã C) exceeds 30 years.
Model and meaning:


Structural features:
TG-12 (V, C, F)/630-25 fully enclosed and insulated ring main switch cabinet series inflatable cabinet SF6 gas is used as arc extinguishing and insulation medium.
The switchgear is a fully sealed and insulated structure; The busbar, switch, and live parts are completely enclosed in a stainless steel casing.
The chamber is filled with SF6 gas at 1.4 bar, with a protection level of P67. The entire switch device is completely unaffected by external environmental conditions, ensuring normal operation even in extreme situations such as short-term water immersion. The product is maintenance free for life.
The switchgear has a complete "five prevention" interlocking device, which completely eliminates personnel and equipment operation failures that may be caused by human error.
All switch cabinets have reliable safety relief channels, which can ensure the personal safety of operators even in extreme situations.
Switchgear is divided into two types: fixed unit combinations and expandable unit combinations;
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, remote control, and detection devices according to different user needs
