PVC Insulated Parallel Drop Wire is a specialized communication cable designed to connect telephone circuits from distribution points (e.g., poles or terminals) to subscriber premises. With a parallel conductor layout and PVC insulation, this drop wire is ideal for aerial installations, particularly in residential or commercial telephony systems.
Applications
-
Telephone line extension from poles or distribution boxes to buildings
-
Ideal for aerial drop installations in telecom networks
-
Suitable for residential, commercial, and rural communication systems
-
Used in voice and low-speed data transmission
