What Is The Difference Between UL1007 And UL1061?

In the UL standard system, each type of wire has unique markings and specifications. UL1007 wire and UL1061 wire are two common and easily confused electronic wire models. Both have a rated voltage of 300V and can withstand an operating temperature of 80°C. So, which one should be chosen?

01 Core Differences
Engineering technicians are often confused by UL1007 and UL1061 electronic wires. After all, they are extremely similar in many parameters: both use PVC insulation, both have a rated voltage of 300V, and both have a rated temperature of 80°C.

The differences between these two are actually quite subtle yet crucial. We can distinguish them from several key dimensions:

• Insulation material and thickness are the primary distinguishing points.

UL1061 uses semi-rigid PVC (SRPVC) as insulation material, with an average insulation thickness of 9mil (approximately 0.23mm), and no point less than 7mil (approximately 0.18mm). In contrast, UL1007 uses standard PVC insulation with a higher thickness requirement, a minimum average thickness of 15 mil (approximately 0.38 mm), and no point less than 13 mil (approximately 0.33 mm).

• Physical properties and application characteristics also differ.

Due to the use of semi-rigid PVC insulation, UL1061 wire performs better in maintaining its shape, making it suitable for applications requiring neat wiring and installation in compact spaces.

Conversely, UL1007's standard PVC insulation offers better flexibility, making it more suitable for applications requiring frequent bending or movement.

Regarding conductor size range, both wires support conductor sizes from 32/30 AWG to 16 AWG, and can be used with solid or stranded conductors. However, UL1061 has more applications in core wire fabrication.

02 Technical Parameter Comparison

To more intuitively demonstrate the technical differences between UL1007 and UL1061, we have compiled a detailed technical parameter comparison table:

From the conductor structure perspective, UL1007 electronic wires typically use tinned copper or bare copper as the conductor material.

Taking 18 AWG as an example, the conductor of UL1007 wire may consist of 41 strands of fine copper wire with a diameter of 0.16mm twisted together, with an overall outer diameter of approximately 1.18mm, an insulation thickness of 0.41mm, and a final outer diameter of approximately 2.00mm.

In terms of electrical performance, the maximum conductor resistance of UL1007 wire varies with the wire gauge. For example, the resistance of 30 AWG is approximately 361Ω/km, while that of 16 AWG drops to 14.6Ω/km. This type of wire also needs to pass UL VW-1 and CSA Ft1 vertical flame resistance tests to ensure safety in fire conditions.

03 Application Scenarios and Selection

After understanding the differences in technical parameters, the most crucial question is: in what situations should one choose which type of wire?

UL1061 is primarily used in environments where space utilization and wiring neatness are critical. Due to its semi-rigid PVC insulation's ability to better maintain its shape, it performs excellently in the internal wiring of electronic equipment requiring compact installation.

UL1061 is particularly suitable for internal wiring in electric bookkeeping machines, accounting machines, time recorders, or electronic devices. It is often a better choice when wires need to pass through confined spaces or maintain a specific shape.

UL1007 has a wider range of applications. In addition to internal wiring in general electrical equipment, it is suitable for environments where there may be contact with oils and temperatures do not exceed 60°C or 80°C (depending on the application).

UL1007 can be found in many fields, including home appliances, automotive electronics, sensor materials, smart homes, lighting equipment, and medical devices.

The key to making an informed choice is to fully consider the application requirements: if your project requires neat and orderly wiring within a limited space and the wires do not require frequent bending, then UL1061 may be a better choice.

Conversely, if the application environment requires better wire flexibility or may involve contact with oily substances, then UL1007 would be a more suitable choice.

04 Purchasing Guide and Safety Considerations

Choosing the right electronic wire is not only related to equipment performance but also directly related to usage safety. Several key factors need to be considered when selecting UL1007 or UL1061 electrical wire.

• Electrical parameter matching is the primary consideration.

Ensure that the rated voltage and current capacity of the selected wire meet the application requirements. For UL1007 electrical wire, its rated voltage of 300V and operating temperature of 80°C make it suitable for most low-voltage applications.

However, environmental adaptability is equally important. UL1007 can withstand oil temperatures up to 80°C in environments where oil may be present. UL1061, on the other hand, is more suitable for dry indoor environments where shape retention is required.

Wire gauge selection also needs careful consideration based on the specific application. Thicker gauges (e.g., 16 AWG) can carry higher currents, while thinner gauges (e.g., 30 AWG) are better suited for space-constrained applications. Incorrect wire gauge selection can lead to overheating and even fire hazards.

• Certification and compliance are crucial.

Ensure that the selected wire has complete UL certification, which is an important guarantee of product safety and a requirement for market access in North America.

• Supplier selection is also crucial.

Finding suppliers with extensive experience, a robust quality control system, and excellent after-sales service ensures you receive products that meet standards and offer stable performance.
