Splicing Shielded MV Cable to Non-Shielded MV Cable
Splicing Shielded MV Cable to Non-Shielded MV Cable
(OP)
I have a situation where we need to splice a length of shielded 8kV rated cable to non-shielded 5 kV cable for a failure repair on a 4160 volt system. Does anyone know if the 8kv cable can be treated similarly to the unshielded cable within the splice or will excessive voltage stresses be present without properly terminating the shielded cable conductors? The cable and splice kit manufacturers do not have information available to address this situation.

Is there any reason for using 8 KV cable on 4,160 volts? 5 KV 3 conductor metal clad cable that has only the sheath as an overall shield works quite fine on 4,800 volts ungrounded.

Also, most codes require the shield to be grounded regardless of presence of armour jacket.
