The UL wire standard, also known as Underwriters Laboratories wire standard, is a standard developed by Underwriters Laboratories in the United States. This standard is not only widely used in the United States, but also recognized and adopted in many other countries and regions. The UL wire standard is known for its strict testing requirements and rich product certification system, covering almost all wire products in the electrical industry.
The UL wire standard provides detailed specifications for various performance indicators of wire products.
1. The electrical performance of wires, including rated voltage, current carrying capacity, etc.
2. The insulation and heat resistance of wires require good insulation materials and high temperature resistance to ensure their long-term stable operation in complex electrical environments.
3. The UL wire standard also imposes strict requirements on the flammability, weather resistance, mechanical strength, and other aspects of wires to ensure the safety and reliability of products under various harsh conditions.
Some of UL wire standards are follows:
UL1007 wire 300V 80 °, electronic wire 32AWG-16AWG, single or bare copper, tinned copper wire, standard UL758. Internal connection wires of electronic and electrical equipment;
UL1015 wire 600V 105 ° electronic wire 32AWG -10AWG, single or bare copper, tinned copper wire, standard UL758. Internal connection wires of electronic and electrical equipment;
UL1032 wire 1000V90 ° electronic wire 30AWG-4AWG. Made of Micron or bare copper, tinned copper wire, standard UL758. Internal connection wires of electronic and electrical equipment;
UL1061 wire 300V 80 ° electronic wire 30AWG -16AWG, single or bare copper, tinned copper wire, standard UL758. Internal connection wires of electronic and electrical equipment;
UL1185 wire 300V 80 ° single core shielded wire, 30-4AWG single or bare copper, tinned copper wire, used for recording and playback systems, electronic circuits, etc;

UL1430 wire 300V 105 ° cross-linked PVC wire 30-16AWG, single or bare copper, tin plated copper wire standard UL758 internal connection wire for electronic and electrical equipment;
UL1431 wire 600V 105 cross-linked PVC wire 30-16AWG, single or bare copper, tin plated copper wire standard UL758 internal connection wire for electronic and electrical equipment;
ULI704 wire 300V 150 ° 32-10AWG silver plated, tin plated, nickel plated soft copper wire, PTFE wire, aviation metallurgy petroleum instruments and meters, transformer motor lead wires.
The widespread application of UL wire standards has had a profound impact on the electrical industry.
The UL wire standard effectively ensures the quality and safety of power transmission, providing users with reliable power supply guarantees.
In international trade, UL certification has become the "passport" for wire products, making it easier for products to enter the international market.
The strict requirements of UL wire standards have also promoted technological innovation and production process improvement in the electrical industry, promoting the sustainable development of the industry.
The application of UL wire standards not only covers residential and commercial buildings, but also includes multiple fields such as industrial, transportation, and energy. The requirements for wires vary in different fields, so UL wire standards are further divided into multiple categories and certification levels to meet the needs of various industries.
