Abstract This paper provides a comprehensive technical review of appliance wiring material (AWM) style 2725, as defined under UL 758. The cable is rated for 30 volts and 80°C, with a VW-1 flame rating. It is a flat, parallel-conductor, insulated wire commonly used in low-voltage internal wiring of electronic equipment. The study covers conductor specifications, insulation material, electrical and thermal limits, flammability performance, and typical applications. 1. Introduction AWM 2725 is part of the UL AWM style system, which categorizes wires for use inside factory-assembled appliances and equipment. Style 2725 specifically refers to a single or multiple conductor cable using PVC insulation (polyvinyl chloride), with a voltage rating of 30 V and temperature rating of 80°C. The “VW-1” marking indicates compliance with UL’s Vertical Wire Flame Test.
This paper focuses on the most common physical form of 2725: (similar to “zip cord” or speaker wire), though the style can also apply to singles. 2. Construction Details | Parameter | Specification | |-----------|----------------| | Conductor material | Tinned or bare copper | | Conductor size | Typically 26 AWG to 18 AWG (common: 22 AWG) | | Conductor type | Stranded or solid (stranded more common for flexibility) | | Number of conductors | 2, 3, 4, or more (parallel lay) | | Insulation material | Polyvinyl chloride (PVC) – general purpose | | Insulation color | Red, black, white, green, yellow, etc. | | Overall jacket | None (each conductor individually insulated, no outer jacket for flat parallel types) | | Nominal thickness | 0.38 mm – 0.45 mm (depending on gauge) | awm 2725 80c 30v vw-1 cable
