Cable Codes Are Useful Only When the Project Conditions Are Clear
Product codes such as AC90, TC90 and YJLHV22 help narrow a cable search, but they do not replace an electrical and installation specification. Conductor size, voltage, environment and local requirements still determine what can be used on a project.
Guangdong Tengyuetong Cable lists aluminium-alloy cable products including YJLHS (AC90), YJLHV (TC90), YJLHV22 and low-smoke zero-halogen flame-retardant and fire-resistant cable. The catalogue shows several constructions aimed at different installation conditions.
An enquiry should state the destination standard, system voltage, conductor size or required ampacity, number of cores, installation method and environment. Underground, tray, building and exposed applications do not create the same mechanical and fire-performance requirements. The buyer should also specify drum length, identification marks and any project documentation required.
Terms such as flame-retardant, fire-resistant and low-smoke zero-halogen describe different properties. They should not be treated as interchangeable. Importers and contractors need to verify the exact construction and test documentation for the proposed cable against the rules and design of their project. According to the manufacturer’s published data, YJLHV22 can meet flame-retardant Class IA and fire-resistant Class I under GB/T 19666 and GA 306.
Engineering and procurement teams can review the Tengyuetong cable catalogue before issuing a schedule that identifies every circuit and installation condition.
