Plastic insulated (shielded) control cables are suitable for control, monitoring circuits and protection lines with an AC rated voltage of U0/U of 450/750V and below, and are used as control wiring between electrical equipment.
The main feature of flame-retardant cables is that they are not easy to catch fire or, if they do, the flame spread is only limited to a certain range. They are suitable for occasions with high requirements for flame-retardant performance.
The main feature of fire-resistant control cables is that they can not only transmit electricity under normal working conditions but also maintain normal operation for a certain period of time when on fire. They are suitable for applications where fire resistance is required.
