When it comes to electrical wiring, the selection of the right type of wire is critical for safety and performance. In this way, 12 AWG stranded TW wire, known for its versatility and durability, is perfect for indoor and outdoor applications.
A stranded wire consists of multiple small strands of wire bundled together. This makes it more flexible than solid wire, especially in tight spaces. This stranded wire is 12 AWG thick and about 2.05 mm in diameter. Here are the main types of 12 AWG stranded wire:
Classic TW wire
TS stranded wire is ideal for power distribution and equipment connection. Thanks to its flexibility and heat resistance, it is a popular choice for machinery. TS wire is rated for temperatures up to 60°C in dry environments. This means it can handle a good range of temperatures in average conditions.
MTW wire
Mechanical Temperature Waterproof (MTW) wire is made for tough conditions. It withstands extreme temperatures, ranging from -50°C to 105°C. This makes it ideal for use in industries like refrigeration. The wire also has insulation that protects it from oil and abrasion. So, it is good for machines running in harsh environments.
12 AWG stranded copper wire
12 AWG stranded copper wire is the same as stranded TW wire, except that copper is used instead of copper-clad aluminium. Copper provides better conductivity. This makes it a reliable choice for many electrical applications. TS stranded copper wire is commonly used in residential, commercial, and industrial power distribution.
EMT wire
Like MTW, TS EMT wire is temperature-rated for -50°C to 105°C. However, it is used under different contexts. EMT wires are engineered for waterproof and exposed locations. It is often seen in marine, outdoor, and other wet applications. It has special protection for the copper strands against corrosion and water damage.
Selecting the right 12 AWG stranded wire can make a big difference in the success of an electrical project. Various factors must be considered to determine what suits an application best. Here are the main selection criteria:
Conductor material
12 AWG stranded TW wire is mainly made from copper-clad aluminium. Copper-clad aluminium (CCA) wire consists of an aluminium core coated with a thin layer of copper. It combines the lightweight properties of aluminium with the superior conductivity of copper. This makes it more affordable than pure copper wiring. These properties enable it to deliver strong performance in several applications. Pure copper, on the other hand, provides slightly better conductivity and may be preferred in high-demand situations.
Flexibility
The main reason for choosing stranded over solid wire is its flexibility. 12 AWG stranded wire is made for tight spaces and movable equipment. It is often used in machinery and automotive wiring. For larger installations where the wire runs straight and does not need bending, solid wire may be more suitable.
Insulation
When choosing stranded wire, the insulation material and thickness must be considered. Each type of stranded wire is designed for different applications. For example, MTW and JST wires are made for tough and industrial scenarios because of their durable insulation. TW wire has thinner insulation because its application does not involve that much intensity. However, it is sufficient for indoor and most outdoor usages.
Project requirements
The final consideration for choosing stranded wire is dictated by the project needs. For tasks that require wire to endure harsh environmental conditions, go for a wire like EMT or MTW. They have the sturdiness, temperature rating, and waterproofing features required in this scenario. For more general household or commercial applications, a TW wire is sufficient.
When it comes to wiring, durability is a key factor in ensuring long-term reliability and performance. 12 AWG stranded TW wire is super durable for a wide range of reasons.
Stranded construction
Stranded wire is made by twisting many finer strands together to form a thicker wire. This design inherently provides flexibility. It allows the wire to bend and move without breaking or losing structural integrity. This makes it ideal for applications where the wire may be subject to repeated bending or flexing. Such as in machinery or automotive wiring.
Aluminium copper-clad wire
This wire is made of copper-clad aluminium. This type of wire consists of a core of aluminium coated with a thin layer of copper. While the core is made of aluminium, which is softer and more prone to breaking, the exterior is copper. Since it is a harder metal, it provides more strength to the wire. So, this combination gives the wire both light weight and strength. The aluminium core makes the wire lighter and easier to handle. Thus, it is perfect for installations that require easy manoeuvrability. The copper layer ensures excellent conductivity to prevent frequent power losses.
Thermoplastics insulation
The insulation around the stranded wires adds a significant layer of durability. The insulation is made from thermoplastics like PVC. These materials are tough, flexible, and resistant to many types of chemical damage. They also shield the wire from moisture, which is highly dangerous if trapped inside the wire. Different kinds of thermoplastics have varying levels of durability. From the standards of TW wiring, PVC by itself is durable enough to withstand long periods of wear.
Resistance to corrosion
While aluminium does corrode easily, copper-clad aluminium does not. Thus, 12 AWG stranded TW wire is designed for durability in a variety of environments. It can be used in both indoor and outdoor spaces. For outdoor applications, it is often exposed to moisture and weather elements. Therefore, it is crucial for the wire to be resistant to corrosion. With TW wire, the copper-clad strands prevent the wire from breaking down over time when used outside.
Even though 12 AWG stranded TW wire is very durable, proper care plays a key role in its long-lasting performance as well as safety. It should be properly maintained according to how and where it was used. Here are ways this wire can be cared for based on its environment:
Indoor areas
For indoor spaces, maintenance of 12 AWG stranded TW wire often involves regular visual inspections. Technicians should check for any signs of wear, such as fraying or exposed conductor. Physical damage like this can result in short circuits or electrical fires if not found early enough. Besides this, dust and debris accumulation can adversely affect wiring systems. That is why establishments should regularly clean the area around the wires and any accessible wiring junctions. This will prevent buildup from occurring. Finally, environmental factors like heat and humidity can affect electrical wiring. One needs to ensure that the temperature and moisture levels remain moderate. Maintaining a normal indoor environment helps carriers stay in good condition.
Outdoor areas
Outdoor conditions are harsher on stranded wire. The best way to maintain it outdoors is to always do a routine monitoring. Temperature fluctuations, moisture, and exposure to sunlight can all lead to deterioration over time. Thus, it is very important that any signs of damage like fraying, corrosion, or exposed wire are addressed immediately. Corrosion is a major threat to outdoor wires, especially when the area is humid or near saltwater. So, using a corrosion inhibitor or providing extra protective insulation around the wire is necessary. Also, UV rays from the sunlight can degrade the wire’s insulation. That is why it is critical to place the wire in shaded areas when possible. Or cover it with UV-resistant materials. Finally, ensure that the wire is free from debris, vegetation, or animal nests that may be encroaching on the wire. Buildup like this can cause physical damage or interfered with the wire’s function.
Industrial settings
12 AWG stranded TW wire is designed for heavy-duty use. For this reason, it needs regular checks for signs of wear or damage. This is especially so in areas where the wiring is subject to constant movement or mechanical stress. One needs to ensure that there is no fraying or exhaustion with time. In environments where the wire is exposed to chemicals or extreme temperatures, more frequent inspections may be necessary. So, go with protective measures like conduit or cable guards to mitigate damage from chemical exposure or mechanical wear. These guards shield the wire from substances that could degrade its insulation or lead to short circuits.
A1: This wire's flexibility, corrosion and abrasion resistance, and durability make it a good fit for this purpose. Its stranded design allows for easy bending and movement without breaking. This makes it great for tight spaces and areas where the wire may be subject to frequent flexing. The CCA construction enhances its resistance to corrosion and abrasion. Thus, making it suitable for indoor and outdoor applications. The wire withstands mechanical stresses from environmental factors like moisture and extreme temperatures.
A2: It depends on the environment where the wire is found. Those in industrial settings and outdoors should be inspected frequently. Seasonal checks are sufficient for those in indoor spaces.
A3: The 'TW' designates the wire as thermoplastic insulated and suitable for dry conditions. It is also rated for other conditions. For example, the MTW and EMT wires are rated for different environmental conditions.
A4: Yes, it can. It is used for grounding to help redirect electrical currents safely to the ground. This protects people and equipment from electrical faults and surges.
A5: It is not necessarily. Stranded wire is more flexible. This makes it better suited for applications involving frequent movement. But it is not as sturdy. This means it will wear out faster in spaces where there is no movement at all. So, whether one outlasts the other depends on the environment in which they are found.
