Application
KVV22 steel armored control cables (KVVP2-22 copper tape shielded steel tape armored control cable) laid in the case of a fixed chamber, ducts, pipes, direct burial. Signaling control, monitoring and protection circuit lines, electrical instruments, power distribution unit, controlling the use and measurement. (E.g., measurement test, signal display, telemetry self-test, the control computer networking system for transmitting signals, alarms, etc.)
KVV32 steel wire armored control cables are laid in fixed places such as indoors, cable trenches, pipelines, direct burial, and shafts. Use of signal transmission, control and measurement of control and monitoring circuits and protection circuits, electrical instruments and power distribution devices. (Such as measurement test, signal display, self-test telemetry, computer networking, alarm and other signal transmission control systems)
