What are PVC wires?

Undoubtedly, wires that have PVC covering are PVC wires, and you can call them vinyl wires. PVC offers cables high resistance against acids, alkalis, sunlight, heat, weather, oils, and abrasion. In addition, PVC acts as a waterproof jacket for installations requiring high protection. These properties make PVC an excellent outer covering for wires, including underground feeders, street lighting, control, direct burial wires, and aerial wires.

Nonetheless, many PVC compounds do not have extreme high and low temperatures in the same formulation. Instead, they range from -20°C to 60°C. Further, different varieties of PVC have other electrical properties and flexibility.

Application of PVC copper wires

You can find PVC in copper wire products in the form of :

Machine tool wire (MTW) and TEW (thermoplastic equipment wire) 

 

Importantly, MTW and TEW are stranded wires with soft annealed PVC-insulated copper wire. TEW consists of a copper conductor (bare) , whereas MTW wire uses a copper conductor that is tinned. However, TEW has TEW/MTW label as it’s suitable for applications of both the wires. However, tinned copper does not have a decreased efficiency in humid or high heat environments. 

Applications:

First and Foremost, you can use MTW/TEW wire as a general-purpose hook-up wire for appliances’ internal wiring. For example, you can use them in refrigeration equipment, AC equipment, Automatic washers, control panels, and control wiring of machine tools. Generally speaking, you can use them in dry locations less than 90°C  or wet areas. 

Besides, CSA type TEW rating allows the use of wire in dry locations up to 105°C, and in wet areas or in applications where wires come in contact with oils and coolants, it has a rating of 60°C. 

Application wire material (AWM)

AWM wire has a copper conductor (annealed) and Polyvinyl chloride insulation. It is either a solid or stranded wire with a rating of 1000 V.

Applications:

Importantly, You can use AWM wire in machine tool wiring, general-purpose circuit wiring, and appliances’ internal wiring like control panels, air-conditioning equipment, refrigeration equipment wiring, control wiring of machine tools, and automatic washers. Also, according to UL and CSA ratings, you can only use them in dry locations less than 105°C. 

TW/THW wire:

Besides, TW or THW wire is also available in a solid or stranded form with the annealed copper conductor having polyvinyl chloride as cable insulation material. TW or THW means thermoplastic, high heat-resistant, and water-resistant. Importantly, the UL rating for this wire is 600 volts.

Applications: 

Generally, you can use stranded TW/THW wire in standard wiring circuits for internal and machine tool wiring appliances. Typical uses include wiring for refrigeration equipment, control panels, AC equipment, automatic washers, and control wiring of machine tools. In addition, you can use solid TW/THW wires for general grounding purposes such as CATV installations, telephone, and communications, swimming pool lighting, pumps, and traffic light signals. 

You can use this tracer wire, especially in industrial, commercial, and residential applications where it is dry and less than 90°C.
