Yes, if the cables are long enough for the induced voltage at the unearthed end of the armour exceeds 2kV during an external single phase to ground fault.
It is possible that Surge Voltage Limiters (SVLs) may not be required for single bonded 33 kV cables, as they are commonly used for higher voltage levels such as 66 kV and above. However, this may depend on the specific installation and operating conditions.
