■ As an overwrap for protection of terminating high-voltage cables against arcing and tracking. High-voltage cables with these insulations should be overwrapped:
■ Butyl rubber
■ Oil-base rubber
■ Ethylene propylene rubber
■ PVC
■ Low and high-density polyethylene
■ cross-linked
■ As primary insulation where Class "H" (180˚C/356˚F) temperatures are encountered i.e., silicone rubber cables.
■ As splice overwrap on spacer cable operating at 15 kV and above. 3.0 Data Scotch 70 Tape has a peak thickness of 20 mils, an edge thickness of 8 mils, and a blue center guideline. It is available in roll size 1 in. wide x 30 ft. long. The core is 1 in. I.D. 4.0 Specifications Product The insulating tape must be composed of self-fusing, inorganic silicone rubber with an easy-tearing and easy-stripping polyester liner. The product must be Sky Blue Gray and conform to Munsell Color No.5BG7.0/0.4. The tape must be capable of operating continuously at Class H temperatures (180°C/356°F). The tape must be compatible with all synthetic cable insulations as well as cable splicing compounds. Engineering/Architectural Specifications All tape or tape-like terminations which will be operated either outdoors or in areas subjected to contamination or moisture shall be overwrapped with at least one layer of Scotch Silicone Rubber Electrical Tape 70 HDT.
