 FAQ 

What is 20 Gauge 3 Conductor Electrical Double Shielded Wire used for?

It is used for electronic instruments, motors, transformers, electrical appliances, CNC systems, control wiring, signal transmission, power supply connection, and low-voltage electrical equipment where EMI protection and compact three-conductor wiring are required.

What does double shielded wire mean?

Double shielded wire uses two shielding layers, typically aluminum and tinned copper shielding, to improve electromagnetic interference protection and help maintain stable signal transmission in electrical systems.

Why choose double shielded wire instead of ordinary shielded wire?

Double shielded wire is better for applications with stronger interference sources, such as motors, transformers, VFDs, controllers, and electronic instruments. It provides stronger EMI resistance than many single-shielded or unshielded cables.

What are the main specifications of this 20/3 double shielded cable?

This cable is 20AWG with 3 twisted conductors, 300V rated voltage, 80°C rated temperature, 36.7Ω/KM 20°C conductor resistance, tinned stranded copper conductor, PVC insulation and jacket, and 5.3 ± 0.15mm jacket diameter.

What are the conductor colors for this 20 gauge 3 conductor wire?

The conductor colors are Black, Red, and Yellow. This three-core color configuration supports easier identification during control wiring, motor wiring, electronic instrument wiring, and electrical appliance installation.

Why does this double shielded cable use tinned stranded copper?

Tinned stranded copper provides good conductivity, improved solderability, oxidation resistance, corrosion resistance, and better flexibility compared with solid conductors or low-grade conductor materials.

Is this 20AWG double shielded wire suitable for motors and transformers?

Yes. It is suitable for motors, transformers, electronic instruments, and electrical appliances when the voltage, current, temperature, and installation conditions match the cable specifications.

When should I choose 20AWG instead of 18AWG double shielded wire?

Choose 20AWG when the application needs a smaller, lighter, and more flexible three-conductor cable for control wiring or signal wiring. For higher current capacity or longer runs, a larger gauge such as 18AWG or 16AWG may be more suitable.

Can Zhong Hua Jiang provide custom double shielded wire solutions?

Yes. Custom options can be discussed for cable length, conductor size, conductor color, shielding requirement, jacket material, packaging, and application-specific electrical requirements.

How do I request a quote for 20 Gauge 3 Conductor Double Shielded Wire?

You can send your required cable length, quantity, application, voltage requirement, conductor configuration, and working environment to the Zhong Hua Jiang sales team. Our team will recommend a suitable double shielded wire solution for your project.
