The role of the shielded wire is mainly to avoid interference signals entering the inner conductor, while reducing the loss of the transmitted signal. The shielding line can isolate the electromagnetic field noise source from the sensitive device and cut off the propagation path of the noise source. Specifically,

KVV control cable is a PVC insulated control cable, its full name is copper core PVC insulated PVC sheathed control cable. This cable is mainly used for the wiring of control, signal, protection and measurement systems, and has a wide range of applications, often used in voltage levels 450/750V and below control monitoring circuits and protection lines and other occasions.

To determine whether a cable can continue to be used, the following aspects need to be considered:

The installation specification of the cable mainly involves the selection, laying, connection and protection of the cable. The following is a specific introduction:

Because of its excellent anti-interference performance, shielding wire has been widely used in many kinds of equipment. Here are some of the main types of devices that use shielded wires:

There may be a variety of security risks during the use of the cable, which may be caused by the quality problems of the cable itself, improper installation, external environmental impact and other factors.
