How to recognize the various models of UL certified cables
Composition of Model Code
The model code of UL certified cables is usually composed of letters and numbers, which represent different meanings:
Letter section: represents the material, structure, usage environment, or special function of the cable. For example, PVC represents polyvinyl chloride insulation material, and certain letter combinations may refer to specific structural types (such as single core wire, sheathed wire, shielded wire, etc.) or special functions (such as flame retardant, fire-resistant, etc.).
The numerical part usually indicates the specifications and performance level of the cable, such as the cross-sectional area of the wire (possibly expressed in American Wire Gauge AWG), rated voltage, operating temperature, etc. However, it should be noted that the UL wire model does not directly represent the cross-sectional area of the conductor, but is represented using a specific coding system.
Identification of specific models
Some common UL certified cable models and their characteristics include:
PVC insulated cables: such as UL1007, UL1015, etc., which represent American standard single core wires, have a simple structure, and are suitable for connecting various general electrical equipment scenarios.
Sheath wire: such as UL2464, UL2501, etc., an additional layer of sheath is added outside the insulated wire core to provide better protection and is suitable for wiring in complex environments.
Shielded wire: Similarly to UL2464, UL2501, etc. (note that these models may also be sheathed wires), shielded wire adds a shielding layer outside the cable core to reduce the impact of external electromagnetic interference on signal transmission.
