Section 36-48-6 - High Voltage Trailing Cables6.1. The high-voltage trailing cable shall be designed as follows: 6.1.a. A 100 percent semi-conductor tape shielding over each insulated power conductor;6.1.b. A grounded metallic braid shielding over each insulated power conductor;6.1.c. A ground-check conductor not smaller than a number 10 A.W.G.; or if a center ground-check conductor is used, not smaller than a number 16 A.W.G. stranded conductor; and6.1.d. Either a double-jacket or single-jacket as follows:6.1.d.1. A double-jacketed cable consisting of reinforced outer and inner protective layers. The inner layer must be a distinctive color from the outer layer. The color black shall not be used for either of the two protective insulation layers. The tear strength must be more than 40 pounds per inch thickness and tensile strength must be more than 2,400 pounds per square inch.6.1.d.2. A single-jacketed cable. The cable jacket must not be black. The tear strength must be more than 100 pounds per inch thickness and tensile strength must be more than 4,000 pounds per square inch.
