Friday, June 26, 2020

UL 3214 and UL 3231 wires are part of Allied Wire & Cable’s collection of High-Temperature wires, which are wires designed to withstand brutal temperatures and are fairly universal in their applications. High-temperature wires are commonly found in commercial and industrial environments as well as domestic such as household ovens and drying equipment. UL 3214 and 3231 wires share some similarities but also some differences in their specifications.

 

What is UL 3214 Wire?

The UL 3214 wire is designed to be highly flexible due to its silicone rubber insulation, while also possessing an enormous amount of strength and durability. Some of the recommended industrial applications for UL 3214 include motors, lighting fixtures, internal combustion engines, and mercury switch leads. In a more domestic setting, the applications include whole sealed cooking appliances, lighting equipment, computers, therapeutic and electronic devices. This construction allows for a uniform, flexible, concentric, quality construction.

 

What is UL 3231 Wire

Like UL 3214, UL 3231 is also a high-temperature wire designed to be flexible and highly durable. As well as having good electrical properties, UL 3231 wires also have good chemical resistance, do not contain any chlorine or other halogens, and are fungus resistant. Industrial applications for UL 3231 are the wiring of electrical equipment, usually found in hazardous locations where temperature resistance is imperative but it can also be found in domestic settings, such as clothes dryers and other household appliances. UL 3231 is also found in the medical industry and is primarily found in ventilators.
