The cable with Category A rated voltage is used in the situation
requiring not over 1 min. of grounding fault lasting time. For the
cable with Category B rated voltage, the grounding fault lasting
time normally is not over 1 hour, max. lasting time is not over 8
hours, annual ground fault lasting time altogether should not be
over 125 hours, Category C includes all the system expect Category
A and B.
Applications
These power armoured cables are designed for open air installation,
for direct burrial underground, in water, in cable ducts, power
stations, where mechanical damages to the cable may occur.
