Scope

Scope: This document specifies the evaluation index system, evaluation methods, and grade classification for the evaluation of the "Leader" standard of photovoltaic composite cables. This document is applicable to fiber optic composite medium-voltage cables, rated voltage 1 kV and below fiber optic composite low-voltage cables, access network optical-electrical hybrid cables, wireless radio frequency remote unit (RRU) cables Part 3: Optical-electrical hybrid cables, and fiber optic composite overhead grounding wire products for enterprise standard level evaluation. Relevant institutions can refer to and use this document when formulating "Leader" evaluation schemes for enterprise standards. Enterprises can also refer to and use this document when formulating enterprise standards; Main technical content: 4.2.2 Basic Indices 4.2.2.1 The basic indices of fiber optic composite medium-voltage cables include the relevant requirements of NB/T 42050. 4.2.2.2 The basic indices of rated voltage 1 kV and below fiber optic composite low-voltage cables include the relevant requirements of GB/T 29839. 4.2.2.3 The basic indices of access network optical-electrical hybrid cables include the relevant requirements of YD/T 2159. 4.2.2.4 The basic indices of wireless radio frequency remote unit (RRU) cables Part 3: Optical-electrical hybrid cables include the relevant requirements of YD/T 2289.3. 4.2.2.5 The basic indices of fiber optic composite overhead grounding wires include the relevant requirements of GB/T 7424.4. 4.2.3 Core Indices 4.2.3.1 The core indices of fiber optic composite medium-voltage cables include partial discharge test, single-mode fiber attenuation coefficient test at wavelength 1310mm, single-mode fiber attenuation coefficient test at wavelength 1550nm, conductor resistance, and minimum insulation thickness. 4.2.3.2 The core indices of rated voltage 1 kV and below fiber optic composite low-voltage cables include single-mode fiber attenuation
