Full-sealed, All-insulated
All live parts and switches of SFR6-12/24 are enclosed in SF6 air tanks, which are welded by 3mm thick stainless steel plates and have reliable pressure relief channels at the cabinet bottom to realize the maximum operator’s safety protection.Air tanks are connected with insulation busbars, safe and convenient, while busbars and air tanks are isolated from each other to effectively prevent the accident spread in case of failures.

Service Environment
SFR6-12/24 is applicable to various environments such as high/low temperature (+40℃ ~ -40℃), moist, dustiness, pollution, mining, high altitude (2000 m), etc. Short-term water immersion within 24 hours does not affect the use.

Note: For higher-elevation areas, please indicate the specific altitude.

Modular Design
About the modular design, its basic modules are classified into load switch module, composite apparatus module and other special function modules. These modules in free combination form a box-type structure. In the module, any functions have roughly the same internal structure as basic modules.

Flexible Emergence and Expansion Modes
All modules of SFR6-12/24 can achieve the top side or the emergence and expansion of the top extended connections according to user requirements, thus furthest meeting needs of power supply programs.

In compliance with these standards
International standards: IEC600056, IEC60298, IEC60129, IEC60420, IEC60265,
and IEC60694China standards: GB3804, GB3906, and GB11022
