Zhong Hua Jiang 20 gauge 2 conductor electrical double shielded wire is designed for reliable low-voltage signal and control wiring where electromagnetic interference, flexible routing, and stable conductivity matter. The cable uses two twisted 20AWG tinned stranded copper conductors, PVC insulation, a PVC jacket, and double shielding with aluminum foil and tinned copper to support cleaner signal transmission in CNC machines, motors, electronic instruments, transformers, and electrical appliances.

This 20AWG 2 conductor shielded cable is a practical choice for users who need a compact two-core wire for power, signal, sensor, controller, or device connection inside interference-sensitive systems. Compared with unshielded wire, the double shielded structure helps reduce noise coupling and improves wiring reliability in equipment with motors, variable frequency drives, switching power supplies, and control electronics.
The 2-core configuration is suitable for simple positive/negative, signal/ground, trigger, sensor, and low-voltage control circuits. Tinned stranded copper improves solderability, oxidation resistance, and long-term durability, while the PVC jacket provides flexible routing and daily abrasion protection.
For OEM equipment builders, CNC users, maintenance teams, and electronics projects, Zhong Hua Jiang can support standard lengths and customized wiring requirements based on your connector, length, conductor color, and application environment.

The 20AWG conductors use tinned stranded copper for stable conductivity, easier soldering, better surface oxidation resistance, and improved durability compared with lower-grade CCA conductors. For CNC and control wiring, this helps reduce connection failure caused by poor solder joints or corrosion at wire ends.

There are double shielded layers (Aluminium & tinned copper) to achieve premium shielding effect.
The shielding layer helps contain and reduce electromagnetic interference inside and around the cable.
Double shielded cables can provide grounding protection by directing leaked current through the shielding layer, improving safety when the core wire is damaged.
