Description
Two-position oil-immersed load switch:
The FYB-24 type two-position oil-immersed load switch is suitable for integrated transformers with AC frequencies of 50Hz and 60Hz and a rated voltage of 24kV. It is a load switch specially designed and manufactured by our company for the increased voltage class of domestic integrated transformers.
The BYF1-40.5 type two-position oil-immersed load switch is suitable for integrated transformers with AC frequencies of 50Hz and 60Hz, and a rated voltage of 35kV. It is a load switch specially designed and manufactured by our company for the increased voltage class of domestic integrated transformers.
Frou-position oil-immersed load switch:
The YZFN-10 (20) series load switch is suitable for integrated transformers with AC frequencies of 50Hz and 60Hz and a rated voltage of 20kV. It uses transformer oil as the insulation and arc-extinguishing medium, and the operating mechanism is a spring energy storage device. With three-phase linkage, it can accurately and quickly make or break the rated load current. It serves as a control and protection device for industrial and civilian electrical energy in ring-main power supply and dual-power supply systems.
The FYN33 type four-position oil-immersed load switch is suitable for integrated transformers with AC frequencies of 50Hz and 60Hz and rated voltages of 10kV, 24kV, and 35kV. It is an ultra-small load switch specially designed for the specific environment where the space inside the integrated transformer is small and the load capacity requirements of the power grid are constantly increasing. It uses transformer oil as the insulation and arc-extinguishing medium, with spring energy storage and three-phase linkage. It can accurately and quickly make or break the load current. It is suitable for 10kV, 24kV, and 35kV ring-main or dual-power supply line distribution systems.
