UL 1007 Wire

UL 1007 Wire Construction

Conductors

UL AWM 1007 wire uses solid or stranded tinned copper conductors. Tinned copper has superior corrosion resistance and does not oxidize at high temperatures. It is easy to solder, and crimped connections retain their conductivity. Available sizes are from 30 AWG to 10 AWG for stranded conductors and from 28 AWG to 16 AWG for solid conductors.

Choosing Between Solid and Stranded Tin Conductors

Some of the advantages and differences between solid and stranded tin conductors are that solid tin conductors are typically more compact and less prone to breakage in a more uniform diameter than compared to stranded tin conductors. These features can result in solid tin conductors having better electrical performance than stranded tin conductors. However, stranded tin conductors are more flexible and easier to handle and install when compared to solid tin conductors.

Insulation

Allied Wire and Cable's UL 1007 wire uses PVC insulation with a thickness of 16 mils (0.016 inches). UL 1007 PVC insulation has good resistance to oils, acids, and chemicals and retains its flexibility down to minus 40 degrees Celsius. UL 1007 wire insulation has a maximum temperature rating of 80 degrees Celsius.

UL 1007 Applications

UL 1007 hook-up wire is an appliance wiring material suitable for use in the internal wiring of equipment in terms of UL 758. The wire has good abrasion resistance. Typical applications for this wire include the internal wiring of electrical and electronic equipment including switchgear, transformers, generators, and turbines. UL 1007 wires with solid conductors and those with seven strands are semi-rigid and not suited for flexing applications.

Dual Ratings

Most UL 1007 wires have a dual UL 1569 AWM rating, with a maximum usable temperature of 105 C. While still rated for a maximum voltage of 300 volts, UL 1569 wires also comply with the Canadian Standards Association TR-64 requirements that allow a maximum temperature of 90 C. Some wires also carry a dual UL 1581 rating, which permits use immersed in oil up to a maximum temperature of 80 C.

What does the Dual UL 1569 AWM wire rating mean?

The Dual UL 1569 AWM wire rating refers to a type of wire that has been rated by Underwriters Laboratories (UL) for use in electrical and electronic equipment. The dual-rating refers to the "UL 1569" and "AWM" standards. The UL 1569 standard outlines the construction and performance requirements needed for wires and cables to be used as internal wiring of electronic equipment. The AWM rating covers the performance and safety standards needed for wires and cables used in a wide range of appliances and other equipment. Due to UL 1007 wire meeting both UL 1569 and AWM requirements, UL 1007 wire is suitable for use in a wide range of applications in which reliable performance and strict safety standards are required.

What is the CSA TR-64 Standard?

The Canadian Standards Association (CSA) TR-64 is a standard that outlines the performance and safety requirements needed for the certification and testing of telecommunications equipment in Canada. The CSA TR-64 standard applies to many telecommunications equipment that transmits voice, data, and signals in Canada; from modems to telephone systems.
