Laminated tubing is an important technical term in the field of electrical insulation materials, its definition established by the "Terminology for Electrical Engineering" published in 1998. The national standard GB/T 5132-1985, "Test Methods for Electrically Insulated Laminated Tubes," provided the basic testing specifications for this type of product. This standard was submitted and implemented by the National Technical Committee on Standardization of Insulation Materials (TC51), with the China Electrical Equipment Industry Association as the competent authority and Xi'an Insulation Materials Factory as the main drafting unit. It served as the industry's technical basis for a long time before its repeal in 2009. The related technical system also includes standards for sub-products such as circular laminated rolled tubes and molded tubes, as well as specifications for supporting materials such as unsaturated polyester fiberglass mat laminates, forming a complete technical framework for electrically insulated laminated tubing.
As a professional term in the field of electrical engineering, "laminated tubing" was included in the first edition of "Terminology for Electrical Engineering" published in 1998, referring to insulating material products with a specific structure. The establishment of this term provided a terminological basis for related product research and development, testing, and standardization work.
