What special physical properties does the US standard three-core heavy-duty plug UL certified power cord have, such as high temperature resistance and what?

As a power transmission solution designed for industrial and high-end commercial applications, the US standard three-core heavy-duty plug UL certified power cord not only follows strict international standards, but also has a series of excellent physical properties to ensure its reliability and safety in complex and changing environments. The high-quality plastic material used in the outer sheath of the power cord can withstand temperatures up to 105°C, which means that under continuous high temperatures or extreme working conditions, the power cord can still maintain structural integrity and will not soften, deform or lose function due to temperature rise. This high-temperature resistant material usually contains special additives to enhance its thermal stability and antioxidant capacity, thereby extending its service life and reducing aging caused by environmental factors.
The power cord has passed strict flame retardant tests and achieved a high flame retardant rating, which means that when encountering a fire source, the power cord is not easy to ignite, and even if it is ignited, it can quickly extinguish itself, effectively curbing the spread of the fire and protecting the safety of surrounding equipment and personnel. Flame retardant materials contain chemicals that absorb heat, release flame-retardant gases, or form an insulating layer. These mechanisms work together to reduce the burning rate or even completely prevent burning in some cases.
The outer material of the power cord has been specially treated to have high wear resistance, which can resist the friction and pulling that may be encountered in daily use, reducing the risk of failure caused by physical damage. The selection of materials with good tolerance to a variety of chemicals enables the power cord to maintain stable performance and extend its service life in harsh environments such as moisture and corrosive gases. Despite the above high-strength characteristics, the power cord still maintains good flexibility, which is easy to install and wire, and adapts to spatial layouts of different shapes and sizes.
The power cord material has passed the environmental certification of the EU REACH Regulation (Registration, Evaluation, Authorization and Restriction of Chemicals), the ROHS Directive (Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment) and PHAS (Specific Substances of High Concern), ensuring that it is harmless to human health and the environment.
Each power cord must undergo strict internal and external high-voltage testing, appearance inspection and functional verification before leaving the factory to ensure that all performance indicators meet the design requirements. The outer box is equipped with a UL laser anti-counterfeiting label as a basis for product authenticity verification, which increases consumers' purchasing confidence.
The US standard three-core heavy-duty plug UL certified power cord has become the first choice for power transmission in many fields due to its excellent high temperature resistance, flame retardancy, wear resistance, chemical corrosion resistance and environmental protection characteristics, providing users' equipment with a stable, safe and efficient energy supply solution.
