ShZN1 A, ShZN1 B, ShZN2 and ShZN3 sliding voltage link protection cabinets are designed for connection and distribution of secondary circuits of voltage transformers installed at:

• 330-500 kV power lines, 110-500 kV busbars;
• On the high voltage winding of auto transformers of the substations with one-and-a-half-breaker scheme diagram or mesh-connected diagram of the switchboards.

ShZN1 B sliding voltage link protection cabinet is designed for connection and distribution of secondary circuits of voltage transformers installed at:

• 330-500 kV power line;
• 110-500 kV busbars;
• on the high voltage winding of auto transformers of the substations with one-and-a-half-breaker scheme diagram or mesh-connected diagram of the switchboards without an automatic circuit breaker used for voltage circuits of the meters.

ShZN2 sliding voltage link protection cabinet is designed for connection and distribution of secondary circuits of voltage transformers installed at

• 35 kV busbars;
• on the low voltage side of the auto transformer (transformer) and the busbars of the turbine-generator.

ShZNZ sliding voltage link protection cabinet is designed for connection and distribution of secondary circuits of voltage transformers installed at:

• 35 kV lines; 110-120 kV transfer busbars system
• on the 35 kV side of the auto transformer with the highest voltage of 110-120 kV and of other voltage transformers without additional secondary windings.
