20 Gauge 5 Conductor 20/5 Flexible Electrical Double Shielded Wire UL2464 20 Gauge 5 Core Shielded Cable

20 AWG 5 Conductor Double Shielded Wire

20 AWG 5 conductor double shielded wire is a flexible 300V control and signal cable designed for multi-core connections where electromagnetic interference may affect stable operation. It combines five color-coded tinned stranded copper conductors, PVC insulation, a PVC outer jacket, and dual shielding to support reliable wiring in CNC equipment, motors, transformers, electronic instruments, and electrical appliances.

The cable is rated to 80°C (176°F) and has a nominal jacket diameter of 7.0 ± 0.15 mm. Its five twisted conductors are identified by black, red, yellow, white, and green insulation, helping installers separate power, control, sensor, or signal circuits during assembly and maintenance.

Layout of the Electrical Shielded Wire

The cable structure is engineered to balance conductivity, shielding performance, flexibility, and insulation protection. The tinned stranded copper cores improve solderability and resistance to oxidation, while the aluminum and tinned-copper shielding layers help reduce external electromagnetic noise and contain interference generated within the cable.

For best EMC performance, connect the shielding according to the grounding strategy specified by the equipment designer. Grounding practices can vary by machine, controller, drive, and installation environment, so the final wiring method should follow the applicable electrical drawings and local standards.

Advantages of Double Shielded Wire

Why Choose This 20/5 Shielded Cable

Oxidation resistance: Tin plating helps protect exposed copper strands from oxidation and supports dependable soldered or crimped terminations.

Low eccentricity: Consistent insulation geometry helps maintain mechanical protection and stable electrical performance along the cable length.

High conductivity: Stranded copper conductors provide an efficient current path while retaining flexibility for equipment wiring.

Insulation resistance: RoHS-compliant PVC insulation and jacket materials provide electrical separation and everyday abrasion protection in suitable indoor equipment applications.

Tinned Copper Conductor Benefits

Advantage of Tinned Copper
	Tinned Copper	Pure Copper	CCA  (Copper Clad Aluminum)
Easy to Solder
Better Conductivity
Anti-oxidadtion
Anti-corrosion
Sturdy and Durable

Compared with copper-clad aluminum conductors, tinned copper is generally better suited to applications that require dependable conductivity, easier soldering, oxidation resistance, and long service life. The stranded construction also improves flexibility compared with a solid conductor of similar gauge.

Double Shielded Layer for EMI Protection

The cable uses aluminum shielding together with a tinned-copper shielding layer. This dual-layer construction helps reduce electromagnetic interference from motors, drives, switching devices, and nearby power cables, supporting more stable transmission of low-voltage control and signal circuits.

Shielding effectiveness depends on termination quality, grounding, cable routing, bend radius, connector design, and the noise level of the installation. Avoid routing sensitive signal cable parallel to high-current conductors for long distances whenever the machine layout permits separation.

Applications of 20 AWG 5 Core Shielded Cable

This 20/5 flexible shielded cable is suitable for fixed or moderately flexible internal equipment wiring in compatible systems. Typical uses include CNC machine control wiring, spindle and VFD-related auxiliary circuits, transformers, electronic instruments, motors, sensors, switches, low-voltage controllers, and electrical appliances.

The cable should be selected according to current load, voltage, flexing frequency, ambient temperature, chemical exposure, mechanical stress, and applicable installation codes. For continuous drag-chain movement, verify whether a dedicated high-flex chain cable is required instead of a standard flexible shielded cable.

How to Select the Correct Shielded Wire

Choose conductor count first. Five conductors are useful when one cable must carry several control, sensor, or low-voltage circuits. Confirm that the five color-coded cores match the machine wiring diagram.

Check conductor gauge and current. 20 AWG is commonly used for control and signal wiring, but allowable current depends on cable length, bundling, ambient temperature, duty cycle, and installation method.

Confirm voltage and temperature. This configuration is specified at 300V and 80°C. Do not use it beyond the published rating.

Evaluate the noise environment. Double shielding is beneficial near VFDs, motors, relays, switching power supplies, and other EMI sources, but correct grounding and routing remain essential.

Match the mechanical duty. Confirm jacket diameter, minimum bend radius, movement frequency, abrasion exposure, and connector or gland size before installation.

Customer Feedback

FAQ

What is 20 AWG 5 conductor double shielded wire?

It is a five-core flexible electrical cable with 20 AWG tinned stranded copper conductors, PVC insulation, a PVC jacket, and two shielding layers. This configuration is designed for multi-core control and signal wiring where EMI reduction and clear conductor identification are important.

What are the main specifications of this 20/5 shielded cable?

The supplied configuration is rated at 300V and 80°C (176°F), uses five twisted 20 AWG conductors, has tinned stranded copper cores, and has a nominal outer diameter of 7.0 ± 0.15 mm. The conductor colors are black, red, yellow, white, and green.

How does double shielding reduce electromagnetic interference?

The aluminum layer and tinned-copper shielding layer create a conductive barrier around the insulated cores. When correctly terminated and grounded, the shield helps limit external electromagnetic noise and reduces interference emitted by the cable.

Can this cable be used with CNC machines, motors, and VFD systems?

It can be used for compatible low-voltage control, signal, sensor, and auxiliary circuits in CNC machines, motors, transformers, electronic instruments, and VFD-related installations. The final selection must match the wiring diagram, voltage, current, temperature, flexing duty, and grounding requirements.

Is 20 AWG suitable for power wiring?

20 AWG is commonly selected for control and signal circuits rather than high-current power feeds. Actual current capacity depends on cable length, bundling, ambient temperature, installation method, and duty cycle, so the equipment designer should verify the conductor size.

What is the benefit of tinned stranded copper?

Tinned copper offers good conductivity, easier soldering, improved oxidation resistance, and better corrosion resistance at exposed terminations. The stranded construction also provides more flexibility than a comparable solid conductor.

How should the cable shield be grounded?

Grounding depends on the equipment design and EMC strategy. Some systems ground the shield at one end, while others use bonding at both ends. Follow the machine manufacturer’s wiring diagram and applicable electrical standards rather than using a universal grounding rule.

Is this cable suitable for continuous drag-chain movement?

Standard flexible shielded cable may not be suitable for continuous high-cycle drag-chain motion. For moving CNC axes or cable carriers, confirm the required bend radius, cycle life, torsion resistance, and whether a dedicated shielded chain cable is needed.

Can Zhong Hua Jiang supply other gauges or conductor counts?

Other shielded wire configurations are available. Provide the required conductor gauge, core count, length, voltage, temperature, flexing duty, jacket requirements, and application details so the sales team can recommend a compatible cable.

What information should I provide when requesting a quotation?

Specify the required length and quantity, conductor gauge, number of cores, application, operating voltage, expected current, movement or bend requirements, connector or termination needs, delivery country, and any required compliance documentation.
