UL20057 cable consists of Thermoplastic Elastomer (TPE) jacket and highly purity copper stands. There are multi-core options for 2 to 100 conductor wires. Different colors are applied upon each wire insulation for easy identification. UL20057 compliant cable can be supplied on customize or standard base, in various AWG size, configuration, shielding option, designated insulation and jacket wall thickness.
What is UL20057?
UL20057 is an independent style number, as verified accurate to be a safety identification mark for cable with certain critical parameters fulfilled. A cable printed with marking content "UL20057" upon the jacket surface is to declare it is qualified to meet the corresponding safety requirement. UL20057 can be used as a factor of safety combination with other safety regulation, such as CUL, CSA, VDE, CCC, CE, etc.
