Product Description

Product Description

Reinforced Bonding Wire - 19×0.18mm Multi-Core Copper Clad Steel is a durable, mid-gauge conductor built for bonding, grounding, and signal continuity in environments requiring mechanical resilience and long-term electrical stability. Made of 19 strands of 0.18mm copper-clad steel wire, it combines flexibility with reinforced tensile strength, making it ideal for dynamic applications, especially where equipment is exposed to vibration, bending, or environmental stress.

Its multi-core configuration allows for dense current distribution while maintaining reliable mechanical integrity across cable trays, enclosures, and frame bonding points.

 

Key Features

• 19×0.18mm multi-strand design enhances strength and electrical contact

• Copper cladding provides corrosion resistance and low-resistance conductivity

• Steel core delivers high pull strength and fatigue resistance

• Ideal for high-reliability bonding points and flexible grounding applications

• Compatible with solder, crimp, clamp, or braid integration

 

Applications

• Bonding conductors in telecom cabinets and control panels

• Ground continuity wiring in data centers and broadcast systems

• Structural bonding leads in railway, aviation, or marine electronics

• Braided bonding strap reinforcement in EMI shielding setups

• Low-voltage bonding in automation and modular electrical enclosures

 

Quality & Standards

• Complies with ASTM B452 standard for stranded copper-clad steel wires

• Conductivity: approx. 20% IACS

• Inspected for strand balance, twist precision, and cladding integrity

• RoHS / ISO9001 / REACH certified production

• Supplied in reels, bonding-ready coils, or customized cut lengths
