T/CIET 968-2025 Mineral-intensive insulation busbar trough general technical specification
Basic Information
Scope
Scope: This document specifies the usage conditions, rated values, technical requirements, test methods, supplementary requirements for medium-voltage products, and testing and inspection rules of mineral-insulated busbar trunking. It also covers maintenance and service life, marking, packaging, transportation and storage, acceptance, handling, installation, and the construction of system suspension brackets. This document applies to mineral-insulated busbar trunking with a rated voltage of not more than 1,000 V AC and 1,500 V DC, hereinafter referred to as "the product". Considering the characteristics of mineral-insulated busbar trunking products, the requirements for medium-voltage mineral-insulated busbar trunking with a rated voltage range of 3.6 kV to 24 kV can refer to the provisions of this document.
