Introduction
Rated voltage 66kV and 110kV power cables are widely used in power transmission networks, in urban power grids, large enterprises, and new energy power generation.
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.
