18 Gauge 3 Conductor 18/3 Flexible Electrical Double Shielded Wire UL2464 18 Gauge 3 Core Shielded Cable

18 AWG 3 Conductor Double Shielded Wire Overview

Zhong Hua Jiang 18 Gauge 3 Conductor Double Shielded Wire is a flexible 18/3 electrical cable designed for stable signal and low-voltage power transmission in environments where electromagnetic interference may affect equipment performance. The cable combines three twisted tinned-stranded-copper conductors, PVC insulation, an aluminum shielding layer and a tinned-copper shielding layer within a durable PVC jacket.

With a listed 300V voltage rating, 80°C operating-temperature rating and 6.0 ± 0.15 mm jacket diameter, this UL2464 18 AWG 3-core shielded cable is suitable for CNC routers, VFD spindle connections, stepper motors, electronic instruments, automation equipment, 3D printers, audio signal circuits and other installations that require flexible routing and reduced electrical noise.

18/3 Shielded Cable Key Features

This 18 AWG 3 conductor shielded cable is engineered around the practical requirements of industrial wiring: consistent conductivity, flexible installation, corrosion-resistant conductors and layered shielding. It can be supplied in lengths from 5 m to 5,000 m, supporting individual machine builds, maintenance requirements and bulk production projects.

• 18 AWG, 3 twisted conductors: black, red and yellow insulated cores simplify circuit identification.

• Tinned stranded copper: supports reliable conductivity, solderability and resistance to conductor oxidation.

• Double shielding: aluminum foil plus tinned-copper shielding helps reduce EMI and external electrical noise.

• PVC insulation and jacket: flexible, durable and suitable for common equipment-wiring environments.

• Custom supply: cable length and order quantity can be matched to machine assembly, replacement and wholesale requirements.

Specification of 18 AWG 3 Conductor Shielded Wire

18 Gauge 3 Conductor Wire Technical Data

Confirm the required cable length, conductor assignment, termination method, bend requirements and equipment electrical specifications before ordering. For continuously moving cable-carrier applications, verify whether a dedicated shielded chain cable is required rather than a standard flexible shielded cable.

Advantages of Double Shielded Wire

Why Choose This 18/3 Shielded Wire

Tinned Copper Conductor Benefits

Tinned copper places a protective tin coating over the copper strands. For equipment wiring, this construction supports easy soldering and helps protect exposed conductor surfaces from oxidation and corrosion. The stranded design also improves flexibility compared with a solid conductor of the same gauge.

Tinned copper supports conductivity, service life and convenient solder termination.

Aluminum Foil and Tinned-Copper Double Shielding

The two shielding layers surround the insulated conductors to help limit electromagnetic interference entering or leaving the cable. This is particularly useful near VFDs, motors, spindle systems, switching power supplies and other equipment that can generate electrical noise. The shield should be terminated according to the equipment manufacturer's grounding and EMC instructions; it should not be treated as a substitute for a required protective-earth conductor.

Applications of 18 AWG Double Shielded Wire

Transformer	Electronic Instrument
Electrical Appliance	Motor and CNC Equipment

Common uses include CNC router and spindle wiring, VFD control connections, stepper-motor circuits, industrial automation, electronic instruments, transformers, electrical appliances, 3D printers, audio and speaker signal transmission, and other equipment where shielded multi-conductor cable is specified.

How to Select the Correct 18 AWG Shielded Cable

Select the cable by conductor count, voltage, temperature, current, installation movement, jacket environment and shielding requirement. The 18/3 version is appropriate when three insulated conductors are required. Choose 18/2 for two-conductor circuits or 18/4 when an additional insulated conductor is needed.

Before placing a bulk order, provide the machine model, circuit function, required length, operating voltage, expected current, preferred conductor colors, termination method and whether the cable will remain stationary, flex occasionally or move continuously in a cable carrier. Zhong Hua Jiang can then confirm the appropriate cable configuration and supply length.

Customer Feedback

FAQ

What is 18 AWG 3 conductor shielded wire used for?

It is used to carry three electrical or signal conductors in applications where electromagnetic interference should be reduced. Typical uses include CNC routers, VFD spindle systems, stepper motors, automation equipment, electronic instruments, 3D printers, transformers, audio circuits and other low-noise equipment wiring.

What does 18/3 shielded cable mean?

“18/3” means the cable contains three insulated 18 AWG conductors. In this product, the three conductors are twisted and surrounded by aluminum and tinned-copper shielding layers, with an overall PVC jacket.

What are the voltage and temperature ratings?

The listed rated voltage is 300V and the listed rated temperature is 80°C / 176°F. The final suitability depends on the complete circuit, installation environment and applicable electrical standards.

How does double shielding help reduce EMI?

The aluminum foil and tinned-copper shielding layers form conductive barriers around the insulated cores. When terminated correctly, these layers help control electromagnetic and radio-frequency interference that may otherwise affect signal stability or nearby equipment.

Should the cable shield be grounded at one end or both ends?

Shield termination depends on the equipment, frequency range, enclosure bonding and EMC design. Follow the CNC, VFD, motor or controller manufacturer's wiring instructions. Do not use the shield as a replacement for a required protective-earth conductor.

Is this cable suitable for continuous motion in a drag chain?

Standard flexible shielded cable may be suitable for fixed or occasional-flex installations, but continuous high-cycle motion generally requires a cable specifically designed for drag chains. Provide the bend radius, travel distance, speed and cycle rate so the correct cable type can be confirmed.

What is the difference between 18/2, 18/3 and 18/4 shielded cable?

All three use 18 AWG conductors, but the conductor count is different. An 18/2 cable has two insulated conductors, 18/3 has three and 18/4 has four. Select the conductor count required by the circuit rather than leaving unused conductors unless the equipment design allows it.

Can the cable length and order quantity be customized?

Yes. The listed supply range is 5 m to 5,000 m. Send the required length per roll, total quantity, application, destination market and any packaging or labeling requirements for quotation confirmation.

What information should I provide when requesting a quote?

Provide the cable gauge, conductor count, required length, estimated quantity, voltage, current, machine or equipment model, installation movement, preferred termination and delivery destination. These details help confirm the appropriate cable and produce an accurate quotation.

How does Zhong Hua Jiang control product quality?

Product categories undergo quality-control checks before leaving the factory, and shipment inspection is performed before dispatch. Buyers should also request the current specification sheet, test documentation and compliance files required for their project.
