UL21765 cable is fabricated from Thermoplastic Polyurethane (TPU) jacket. It is multicore with options for 2 to 100 conductor wires. Different colors are applied upon each wire insulation for easy identification. UL21765 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 UL21765?
UL21765 is an independent style number, as verified accurate to be a safety identification mark for cable with certain critical parameters fulfilled.
