T/CES 028-2019 35 kV and below solid insulated copper-clad aluminum tube busbar
Basic Information
Scope
Scope: This standard specifies the structure and technical requirements of solid insulated copper-clad aluminum tube busbars, as well as the test items, test methods, and packaging and transportation methods for solid insulated copper-clad aluminum tube busbars. This standard applies to phase-separated solid insulated copper-clad aluminum tube busbars with a nominal voltage of 35 kV or less, a current of 40 kA or less, and a frequency of 50 Hz (or 60 Hz), formed by the extrusion process. Main technical content: In view of the shortcomings of the original standards GB/T 8349-2000 "Metal Enclosed Busbars" and DL/T 1658 "35 kV and Below Solid Insulated Tube-Type Busbars", such as low electrical performance and safety factors; 1. high temperature rise and high power loss; 2. poor overload capacity; 3. low insulation level; 4. high consumption of copper materials and high cost. In order to improve the performance of busbars, enhance safety, and at the same time save energy, reduce copper consumption, lower costs, and maximize resource utilization efficiency, the "35 kV and Below Solid Insulated Copper-Clad Aluminum Tube Busbars" standard is proposed, filling the gap in industry standards. This standard references and lists the main indicators of some GB and IEC standards.
