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.

1.Test methods and requirements. The purpose is to specify the general Requirements for test methods and procedures.

1 Scope

GB/T 11017.3-2024 is the Chinese national standard on power cables with cross-linked polyethylene insulation and their accessories for rated voltage of 66 kv (um=72.5 kv) and 110 kv (um =126 kv) - part 3: accessories, in the field of electrical engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 29 September 2024 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 April 2025. Classification: ICS 29.060.20, CCS K13. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the conditions of use, product naming, technical specifications, and other requirements of accessories for cross-linked polyethylene insulated power cables with rated voltages of 66 kV and 110 kV. Technical requirements, testing and acceptance rules, packaging, transportation and storage. This document is applicable to outdoor terminals for cross-linked polyethylene insulated power cables with rated voltages of 66kV and 110kV under general installation conditions. Terminals, GIS terminals, oil-immersed (transformer) terminals, straight-through connectors and insulating connectors.
