This standard applies to materials, constructions, and testing of 2001-5000 V nonshielded power cables having insulations of crosslinked polyethylene (includes both crosslinked and tree-retardant crosslinked polyethylene) or crosslinked rubber of the types shown in section 4. The insulation shall be covered with a discharge-resistant jacket or shall be a discharge-resistant material without a jacket. Discharge-resistant insulations and jackets shall comply with the applicable surface resistivity, U-Bend discharge, and trackresistance requirements of sections 4 and 5. The nonshielded cables described in this standard are intended for use for the distribution of electrical energy in normal conditions of service in indoor, outdoor, aerial, underground, or subsea installations within the application limits shown in Table 4-3 and section 5.2.1. They are not intended for portable use applications.
