GB/T 11017 is a product standard for power cables and accessories with rated voltages of 66kV and 110kV. The naming rules, test methods, technical requirements, etc. of power cables and accessory systems are planned to be composed of three parts. --- Part 1.Test methods and requirements. The purpose is to specify the general Requirements for test methods and procedures. --- Part 2.Cables. The purpose is to unify the classification, naming, structure and technical specifications of power cables with rated voltages of 66 kV and 110 kV. Technical requirements. --- Part 3.Cable accessories. The purpose is to unify the classification, naming, Structural and technical requirements. Rated voltage 66kV (Um=72.5kV) and 110kV (Um=126kV) Cross-linked polyethylene insulated power cable Part 2.Cables and their accessories1 ScopeThis document specifies the basic structure, model name, and specifications of copper core and aluminum core cross-linked polyethylene insulated power cables with rated voltages of 66kV and 110kV. name, technical requirements, test and acceptance rules, packaging, transportation and storage.

Note. Usually used for calculation of other dimension values. 3.2 A composite sheath having a longitudinally wrapped metal tape or a longitudinally wrapped metal foil bonded to the non-metallic outer sheath of the cable, the metal tape (foil) of the composite sheath being bonded to the outer sheath of the cable. The seams are bonded by melting plastic or adhesive to form a watertight seal. Note. Usually the metal layer is bonded to the polyethylene sheath to form a metal-composite polyethylene sheath.4 Usage Features4.1 Rated voltage Rated voltage is the reference voltage for cable design and electrical performance testing. This document uses U0/U and Um as symbols. The meanings of these symbols are as follows. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 11017.2-2024_English be delivered?Answer: Upon your order, we will start to translate GB/T 11017.2-2024_English as soon as possible, and keep you informed of the progress.
