Zhong Hua Jiang 18 Gauge 4 Conductor Double Shielded Wire is a flexible 18/4 electrical cable designed for stable signal and low-voltage power transmission in equipment environments where electromagnetic interference may affect control accuracy. It combines four twisted tinned-stranded-copper conductors, PVC insulation, aluminum shielding and a tinned-copper shielding layer inside a durable PVC jacket.
With a listed 300V voltage rating, 80°C temperature rating and 6.5 ± 0.15 mm jacket diameter, this UL2464 18 AWG 4-core shielded cable is suitable for CNC routers, VFD spindle wiring, stepper-motor control, automation equipment, electronic instruments, 3D printers and multi-core signal circuits that require flexible routing and improved EMI resistance.

This 18 AWG 4 conductor shielded wire is built for users who need a practical cable for multi-core wiring, control signals, low-voltage equipment connections and custom electrical projects. The four conductor colors—black, red, yellow and white—help simplify circuit identification during installation and maintenance.
Compared with unshielded multi-core wire, the aluminum and tinned-copper double shielding structure helps reduce noise coupling from motors, VFDs, switching power supplies and nearby electrical devices. The tinned stranded copper conductors support good solderability, oxidation resistance and flexible handling during assembly.
Zhong Hua Jiang can supply this flexible electrical double shielded wire in custom lengths for machine builders, replacement wiring, maintenance work, OEM equipment assembly and wholesale projects. Standard order discussions can include cable length, roll packaging, application, quantity and destination market requirements.

The double shielded structure uses aluminum and tinned copper shielding to help achieve a stronger shielding effect than a basic unshielded cable. The shielding layer can help contain electromagnetic fields inside the cable and reduce external interference entering sensitive conductors.
In practical equipment wiring, the cable shield should be terminated according to the controller, VFD, motor or machine manufacturer's grounding and EMC instructions. The shield is used for interference control and should not be treated as a replacement for a required protective-earth conductor.

“18/4” means the cable contains four insulated 18 AWG conductors. In this product, the four conductors are twisted and protected by aluminum and tinned-copper shielding layers inside an overall PVC jacket.
The listed rated voltage is 300V and the listed rated temperature is 80°C / 176°F. Final suitability depends on the circuit design, load, installation environment, applicable standards and machine-manufacturer requirements.
The aluminum foil and tinned-copper shielding layers form conductive barriers around the insulated conductors. When terminated correctly, these layers help reduce interference from motors, VFDs, power supplies and other noise sources, improving signal stability in sensitive equipment wiring.
Shield termination depends on the equipment, frequency range, enclosure bonding and EMC design. Follow the CNC controller, VFD, motor or equipment manufacturer's wiring instructions. The cable shield should not replace a required protective-earth conductor.
Both use 18 AWG conductors, but 18/3 has three insulated conductors and 18/4 has four. Choose 18/4 when the circuit requires an extra insulated conductor for additional control, signal, power or return wiring.
Standard flexible shielded cable may be suitable for fixed or occasional-flex installations. Continuous high-cycle motion generally requires a cable specifically designed for drag chains. Provide bend radius, travel distance, speed and cycle frequency so the proper cable type can be confirmed.
Yes. The available length range is 5 m to 5,000 m. Buyers can provide the required roll length, total quantity, packing preference, labeling needs, application and destination market for quotation confirmation.
