What is UL 3067-2020?

UL 3067-2020 is a technical standard that specifies safety requirements for flexible cables used in the electrical and electronic equipment. This standard was developed by Underwriters Laboratories (UL), a widely recognized global safety certification company. The purpose of UL 3067-2020 is to ensure the safe and reliable operation of these cables, reducing the risk of electrical fires, shocks, and other hazards.

Key Requirements of UL 3067-2020

UL 3067-2020 covers various aspects of flexible cables, including their construction, materials, and performance. In order to comply with this standard, manufacturers must meet several key requirements:

Insulation and Jacket Materials: The standard specifies the types of materials that can be used for insulation and jacketing of flexible cables. These materials must have adequate flame resistance and resistance to chemicals, moisture, and other environmental factors.

Conductor Size and Design: UL 3067-2020 defines the minimum and maximum conductor sizes allowed for different applications. It also provides guidelines for conductor design, ensuring proper current carrying capacity and flexibility.

Mechanical Strength and Flexibility: The standard sets requirements for the mechanical strength and flexibility of the cables, ensuring that they can withstand bending, twisting, and other forms of mechanical stress without damage.

Electrical Properties: UL 3067-2020 specifies the electrical characteristics of the cables, including voltage ratings, insulation resistance, and dielectric strength. These properties are essential for safe and efficient electrical transmission.

Performance Testing: Manufacturers must perform various tests on the cables to ensure their compliance with UL 3067-2020. These tests include flame tests, temperature cycling, and mechanical stress tests, among others.
