SPEC 44030
1/C CU EPR Medium Voltage Non-Shielded Jumper & Switchgear Cable
Single Conductor Flexible Conductor with an EPR Insulation Non-Shielded Jumper Cable
Construction:
- Conductor:Flexible rope lay stranded annealed bare or tinned copper
- Conductor Shield:Nylon semi-conducting tape, helically applied
- Insulation:Heat, moisture, and ozone resistant Ethylene Propylene Rubber(EPR)
Applications and Features:
Southwire’s medium voltage non-shielded jumper and switchgear cable is a flexible power cable that is intended for use in substations installed on insulators and inside switchgear isolated from ground and where a non-shielded flexible cable is desired. These cables are capable of operating continuously at a conductor temperature not in excess of 90°C.
This cable is rated up to 40KV and is not UL listed. See Table 2 for installation guidelines
