Communication cables
Wire for field communication P-274 M
Application
Designed for field communication with an operating voltage of up to 200 V.
The wire is used for installation in the ground, on the ground, suspended on poles or local objects, and also can be used temporarily through water barriers. It is allowed to lay wires into the ground and excavate from the ground using field means of mechanization.
Cable design
1. Conductor: copper wire.
2. Jacket: PE.
