Unscreened Unarmored Cable

Control cable is a type of cable that connects from the control center to various systems to transmit signals. It is used in control, monitoring, and protection circuits with a rated AC voltage of 450V/750V or below.

Due to the characteristics of unscreened unarmored cable, which has advantages in certain specific applications.
