T/FQIA 002-2022 Rated voltage of 450/750V and below cross-linked polyolefin insulated cable
Basic Information
Scope
Scope: 1 Scope This document specifies the usage characteristics, designations, models, specifications, product representation methods, technical requirements, finished product testing, marking, inspection, acceptance rules, and packaging of cross-linked polyethylene insulated cables with a rated voltage of 450/750 V and below. This document applies to cross-linked polyethylene insulated cables with a rated voltage of 450/750 V and below, where the maximum allowable long-term operating temperature of the conductor is 90 °C. Note: It is recommended to choose these cables with caution in humid environments, especially when installed in metal pipes or buried directly.
