What ls High Temperature Wire?

Selecting electrical cords for high temperature environments is critical and is one of the initial decisions that need to be made when operating electrical equipment in high temperature conditions. When choosing between different types of wire, such as regular wire and high temperature wire, careful consideration needs to be given based on their ability to withstand extreme heat.

In this article, we will take an in-depth look at what high temperature wires are, the types of high temperature wires, and how we can choose the right high temp appliance wire. If you would like to learn more about the various types of wires, keep visiting our wire guide.

What ls High Temperature Wire?

Understanding “meaning”and “application”

  • High temperature wire can work well at high temperatures without melting, deteriorating, or being damaged. The type of electrical wires are made of high temperature resistant materials processed by special techniques. Characteristics of this material: 1.high temperature resistance; 2.corrosion resistance; 3.aging resistance

  • What are some of the common high temperature areas we see? Examples include aerospace, automotive, electronics and industrial manufacturing. This wire promotes the safe and efficient operation of electrical systems even in these various harsh conditions.

1.In the aerospace industry, high temperature wire is used to prevent aircraft failures, as the speed of an aircraft or other vehicle during flight can cause high temperatures in critical areas such as the engine.

2.In the automotive industry, the car in the process of operation will make the car’s engine, exhaust system and turbocharger temperature, the use of high-temperature wire can keep the vehicle’s electrical connections stable.

3.Heating appliances. Some heating appliances will use high-temperature wire, such as electric grills, furnaces and kilns for firing porcelain, etc., use high-temperature wire to keep the appliances working properly.

4.In the industrial environment, steel or glass manufacturing and other high-temperature processes require wires that can withstand high temperatures.

If in the above scenario, high temperature wire is a good choice!

Now that we understand the meaning and applications of high-temperature wire, let’s explore the different types of high temperature wire conductor types.

High temperature wire conductor types

Ordinary electrical wire conductors are basically made of pure aluminium and pure copper. But there are different types of conductors for high-temperature appliance wire, which are described separately below.

1. Tinned copper

Tinned copper is a thin layer of metallic tin wrapped around the surface of copper. Tinned copper prevents the formation of patina. The benefits of the patina become apparent when the copper is exposed to the air, it will enhance electrical resistance and prevent the copper from oxidizing.

2. Bare copper

It refers to a pure copper conductor, which means that the copper’s surface is not plated with anything. It is the most common electrical wire conductor and is extremely conductive.

3. Pure silver plated copper

Pure copper silver plating is a thin layer of silver plated on the outer layer of pure copper conductor. It is easy to polish, good reflective properties and thermal conductivity, electrical conductivity, welding performance. It shows high performance if corrosive conditions exist.

4. Nickel plated copper

A thin layer of nickel element plated on the surface of pure copper is nickel-plated copper. And nickel has a strong passivation ability, its surface can quickly produce a very thin passivation film. It can resist the corrosion of atmosphere, alkali and certain acids. Therefore the abrasion resistance and service life of the metal wire are improved.

These are the four commonly used conductor types for high-temperature wires. Regarding the insulation types of high temperature wires, let’s move on to see what’s available.

High temperature wire insulation types

There are also different types of high temperature lead wire insulation, and these are the main types analysed below.

  • PFA(Perfluoro alkoxy insulation)-PFA is a fluoroplastic. It has good corrosion resistance and high temperature stability. It can withstand temperatures up to 250 ℃. In addition the insulating material has a strong surface tension and good resistance to adhesion and abrasion. This material is appropriate for high temperature oven wire.

PFA

  • FEP (Fluorinated Ethylene Propylene insulation) –FEP is a chemical that is applied to high-temperature wires as insulation and will make the wire stretch easier and more abrasion resistant. It does not ignite, stops the spread of flames and can withstand a maximum temperature of 200 ℃. It is also resistant to chemicals.

FEP wire is a type of wire that is insulated or jacketed with fluorinated ethylene propylene (FEP) material. FEP is a type of fluoropolymer that has excellent electrical properties, broad temperature range, and chemical resistance.

  • PTFE (Polytetrafluoroethylene insulation)-PTFE is a polymer that is both heat and cold-resistant and can operate between -60 and 260 ℃. For extreme operating environments, this material is well suited for use as electrical wire insulation. It is chemically and abrasion resistant, and it has good electrical conductivity.

PTFE

  • Silicone insulation-Silicone material has strong waterproof and moistureproof performance and high heat resistance. The maximum working temperature can reach 200 ℃. And it is soft, easy to carry out complex installation. At the same time, it also has good resistance to acid, alkali and mold characteristics.

Of these four insulation types, each has its own advantages and focus for use. This is where we need to be more aware of the application and the gauge of the wire.

High temperature wire gauge

High-temp wire is used in different application scenarios, and different specifications will be used. The most commonly used is high temperature wire 12 awg. The following is the high-temperature wires gauge.

GaugeOuter Diameter (mm)Max. Conductor Resistance DC 20℃(Ω/km)Packing(m)
10 gauge high temperature wire4.033.546305
12 gauge high temperature wire3.475.64305
14 gauge high temperature wire2.878.96305
16 gauge high temperature wire2.5214.6305
18 gauge high temperature wire2.1723.2305

After knowing the gauge of high temperature wire, we can find out the high-temperature wire vs heat-resistant wire.

High-temperature wire VS Heat-Resistant wire

They both can withstand high temperatures and are interchangeable, which is something they both have in common. But they still differ from one another.

  • In terms of basic concepts, high-temperature-resistant wires are those that can work stably at least above 150°C, while heat-resistant wires are those with heat-resistant wire insulation and shielding.
  • In terms of temperature range, heat-resistant wires operate between 90 and 150°C, while high-temperature wires support normal operation at a minimum of 150°C. High-temperature wire is stronger than heat-resistant wire, so the high-temperature cable standard is higher than the manufacturing standard for heat-resistant wire.

It’s important to keep in mind that the precise composition, design, and intended usage of high-temperature wire can affect its temperature ratings and capabilities. Manufacturers provide specifications and temperature limits for their wires, and it’s important to select the appropriate wire based on the specific requirements of the application to ensure reliable and safe operation.
