What is AWM cable?

AWM (Appliance Wiring Material) cables are defined by Underwriters Laboratories (UL) as an appliance wiring material. These wire types cover a wide variety of cable configurations for many industries and applications, and many continuous flexible cables are manufactured to UL AWM standards.

Key features of AWM cables

  • Flexible Conductors: AWM cables utilize flexible conductors, made of stranded copper or aluminum. This makes the cable easier to work with and route, while also reducing the risk of conductor damage.
  • Durable Jacket: AWM cables feature a durable jacket designed to protect the insulation and conductors from damage. The jacket is typically made of PVC, nylon, or other materials that are resistant to abrasion, moisture, and chemicals.
  • Temperature Resistance: AWM cables are engineered to withstand a wide temperature range, ensuring optimal performance in extreme heat or cold environments. This characteristic guarantees consistent reliability even under harsh conditions.

Applications for AWM Cables

AWM cables are widely used in demanding electronic equipment and electrical systems due to their reliability, durability, and safety.

Common applications are listed below:

  • Internal Connections: AWM cables are used to connect various components inside electronic equipment such as motherboards, graphics cards, hard disk drives, memory sticks, etc.
  • External connections: AWM cables are used to connect electronic equipment to external devices such as monitors, keyboards, mice, printers, etc.
  • Power Transmission: AWM cables are used to transmit power, such as from a power supply to a motherboard or other electronic component.
  • Signal transmission: AWM cables are used to transmit data and signals, for example from sensors to control systems or from computers to network devices.
  • Safety and protection: AWM cables are often flame retardant and heat resistant to prevent fires and malfunctions.

AWM style categories

Underwriters Laboratories (UL) categorizes each variant of AWM into one of five categories. Each category is defined by several characteristics, including the number of conductors, whether a jacket is included, and whether the insulation and jacket are thermoset or thermoplastic.

The following is a list of UL AWM style subdivisions, the meaning of each category, and some common examples:

  • Part 1 (1000-1999; 10000+) – Single conductor, thermoplastic insulation
  • Part 2 (2000-2999; 20000+) – Multi-conductor, thermoplastic insulators and jacketing
  • Part 3 (3000-3999) – Single conductor, thermoset insulation
  • Part 4 (4000-4999) – Multi-conductor thermoset insulated sheathed wire
  • Part 5 (5000-5999) – Single Conductor and Multi-Conductor Specialties

Complexity of AWM Styles

Because of the large number of AWM styles available, the subject matter can easily become very complex. Different types of AWM wire may have different temperature ratings, voltage ratings, insulation types, colours, sizes, and lengths.

To make things even more complicated, different types of AWM wire may have different UL numbers. For example, UL 1007 wire is a common type of AWM wire that has a voltage rating of 300 V and a temperature rating of 80°C. UL 1015 wire is another common type of AWM wire that has a voltage rating of 600 V and a temperature rating of 105°C.

Importance of Choosing the Right AWM Wire

It is imperative to choose the correct type of AWM wire for your specific application to ensure it meets your needs and complies with relevant safety standards. If you are unsure which AWM wire is right for your application, consult with a qualified professional.
