PVC Insulated Drop Service Wire DV is a specialized telecommunication cable meticulously designed for extending telephone circuits from the main distribution network directly to subscriber premises. Characterized by its robust construction and often an oval or dumbbell shape for easy conductor separation, this wire ensures reliable voice and data transmission for the 'last mile' connection.

Applications

The DV Drop Service Wire is specifically engineered for:

Subscriber Access: Designed for use in extending telephone circuits to individual subscriber premises.
Aerial Drop: Ideal for aerial installations, forming the final connection from distribution wires or cables (e.g., from a utility pole) to the subscriber's building.
Residential and Commercial Connections: Suitable for establishing telecommunication services in various residential and commercial settings.

Construction

The robust construction of the PVC Insulated Drop Service Wire DV ensures durability and consistent performance in outdoor aerial environments:

Conductor: Made from Hard-drawn copper wire for electrical use. This material provides excellent conductivity while offering the necessary tensile strength for aerial self-support. For specific sizes (e.g., 22㎟ to 60㎟), hard-drawn copper wire is exclusively used.
Insulation: Each conductor is insulated with Polyvinyl Chloride (PVC/C). PVC insulation offers good electrical properties, mechanical protection, and resistance to environmental factors.
Inner Cord Differentiation: For multi-core versions, color coding is used to differentiate individual conductors:
- 2 Core: Black, Green or Black, Blue
- 3 Core: Black, Green, Blue
- Parallel: Black (for flat configurations where conductors run side-by-side)
Shape: The wire may feature an oval/dumbbell shape to facilitate easy separation of conductors during installation.
