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
Construction
| Component | Description |
|---|---|
| Conductors | 2 parallel conductors, typically copper-clad steel (CCS) for strength and conductivity |
| Insulation | Polyvinyl Chloride (PVC) – durable and flexible |
| Configuration | Parallel layout for ease of routing and installation |
| Optional Feature | Available in self-supporting versions with additional strength member |
