Application

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. <br> <br> This cable is rated up to 40KV and is not UL listed. See Table 2 for installation guidelines
