What is the voltage protection of rubber equipment rated 2?

Rubber equipment rated 2 refers to insulating devices that provide voltage protection based on their classification. The designation "rated 2" typically indicates that the rubber equipment is suitable for use in environments where higher voltages may be present, specifically for voltage ranges that require robust protective qualities.

In this context, the voltage protection levels for rubber equipment rated 2 are set at 17,000 volts for AC and 25,500 volts for DC applications. This level of protection aligns with industry standards ensuring electrical safety when working with medium to high-voltage systems. Proper usage of this rated equipment can help prevent electrical shock and ensure safe working conditions for personnel.

Other options present higher voltage ratings, which do not correspond to the standard classifications for rubber equipment rated 2. Thus, the choice of 17,000/25,500 reflects the appropriate usage and compliance for such insulating materials within the specified protection category.
