T/CAS 699-2023 The wiring harness used in a photovoltaic power generation system
Basic Information
Scope
Main Technical Content: 1. Scope This standard specifies the usage characteristics, product codes, markings, technical requirements, test methods, performance requirements, and packaging, transportation, and storage for wiring harnesses used in photovoltaic power generation systems with a rated DC voltage of 1 kV and 1.5 kV. This standard applies to wiring harnesses that meet environmental requirements for photovoltaic power generation systems, including series cables between PV modules and components on the DC side of the system, parallel cables between modules and to DC distribution boxes (combiner boxes), as well as the corresponding DC connectors for these PV cables (excluding interconnectivity connectors). 2.
