ASTM D1049 outlines the specifications for rubber insulating covers used to protect electrical equipment like bushings and insulators. It defines cover types and voltage classes, and includes dielectric and physical testing requirements to ensure safety and durability.
This standard defines the requirements for rubber insulating covers, which are used to insulate electrical apparatus such as bushings, insulators, and cutouts. It classifies covers by type and class based on their voltage rating and design.
Covers are subjected to dielectric withstand tests and other physical tests to ensure they provide adequate electrical insulation and durability. The standard also includes requirements for marking and traceability. ASTM D1049 is essential for the production of reliable insulating covers, which are crucial for protecting workers from accidental contact with energized equipment.
