Fuses That Should Be Selected For 35kv Lines

Because the voltage level of 35kV lines exceeds the typical range of medium-voltage systems, their insulation distance, creepage distance, arc extinction, and breaking capacity all require higher limits. Therefore, when designing protection schemes, it is essential to use the drop out fuse type fuse suitable for this voltage level. Models such as PRWG2-35 are outdoor fuses specifically designed for 35kV power grids.

While the RW11 series is more commonly found in medium-voltage systems, when the improved 35kV compatible version of this series is put into use, its structure, enclosure, and connection method meet the higher voltage and mechanical load requirements. Therefore, using modified or derived RW11 models as the matching object in 35kV lines is a rational choice for the safe and stable operation of the system.
