Copper Single-Wire Clamp

(Also known as: Copper Single-Bore Clamp, Monobloc Copper Connector)

A Copper Single-Groove Clamp is a fundamental electrical connector used in overhead power distribution systems. Designed for splicing or terminating single-conductor cables, it features a streamlined, one-channel design that ensures secure mechanical grip and low-resistance electrical contact between conductors or to equipment terminals.

Key Features & Functions:
Material:

High-purity electrolytic copper (C11000/C10200) for superior conductivity (≥98% IACS) and corrosion resistance.

Optional tin/silver plating to prevent oxidation in harsh environments.

Design:

Single-groove channel: Accommodates one conductor (e.g., ACSR, AAAC, copper cable).

Compression-type or bolted-type construction for reliable, gas-tight connections.

Smooth radius design to minimize corona effect in HV applications.

Applications:

Tap connections on distribution lines (≤ 33 kV).

Service drops, jumpers, and transformer terminations.

Grounding conductor connections.

Technical Standards:
Complies with IEC 61238 (Compression and mechanical connectors), ASTM B124 (Copper forgings), and UL 486A-B (Wire connectors).

Rated for continuous current up to 600A (varies by size) and fault current withstand per IEEE 837.

Advantages:
Low Resistance: Minimizes power loss (< 20 μΩ/m) and overheating.

Corrosion Resistance: Ideal for coastal/industrial zones (salt/fog resistance).

Lightweight & Compact: Simplifies installation on poles or confined spaces.

Maintenance-Free: Cold-flow copper design maintains contact pressure over decades.

Installation Guidelines:
Surface Prep: Clean conductor with wire brush to remove oxides.

Alignment: Insert conductor fully into the groove.

Fastening:

Bolted type: Tighten hex nuts to specified torque (e.g., 25 N·m).

Compression type: Crimp with calibrated die (e.g., 12-ton hydraulic tool).

Inspection: Verify no gap exists between clamp/conductor; measure contact resistance.

Variations:
Insulated Versions: PVC-coated for safety in crowded line sections.

Bi-Metallic Design: Copper-aluminum interface for mixed-metal systems.

Shielded Type: Integrated stress cone for HV cable terminations.
