The Zhong Hua Jiang 20 AWG 6-conductor double-shielded cable is a six-core cable for CNC control wiring, electrical cabinets, electronic instruments and equipment interconnections. It has stranded tinned-copper conductors with separate color-coded PVC insulation, an aluminum shielding layer, tinned-copper shielding and a PVC outer jacket.
The listed construction has a 300V voltage rating, 80°C (176°F) temperature rating and 7.5 ± 0.15mm outer jacket diameter. Double shielding helps reduce electromagnetic interference in properly installed control and signal circuits. Final cable suitability depends on the wiring diagram, electrical load, environment and applicable installation rules.

Six twisted, individually insulated conductors are surrounded by an aluminum shielding layer and tinned-copper shielding. Together with the PVC jacket, these layers provide a compact wiring arrangement for equipment where interference control and protected conductor routing are important.

Tinned stranded copper supports solderable terminations and helps protect the copper surface from oxidation. The six conductor colors—black, red, yellow, white, green and orange—allow conductors to be identified during machine assembly and maintenance. Screen termination and grounding should follow the equipment manufacturer’s wiring instructions.
For CNC machine builders, control-panel integrators, electrical distributors and maintenance teams, the 20/6 configuration brings six separately identifiable circuits into one cable. Common evaluation points are conductor count, voltage and temperature rating, cable OD, shielding arrangement and the termination method.
This is a 20AWG control and interconnection cable; selection for a motor, moving cable carrier or VFD power output requires separate verification of current capacity, electrical stress, bending requirements and the intended installation. Double shielding alone does not establish suitability for high-power VFD output cables.

The cable combines two shielding elements with tinned stranded-copper cores. The shielding system can help manage externally coupled electromagnetic noise, while the conductor finish supports practical soldering and oxidation resistance. Confirm UL documentation against the exact supplied cable version before procurement for a regulated project.

The comparison above illustrates different conductor materials. Tin plating primarily helps with surface protection and solderability; it should not be interpreted as proof that tinned copper has higher intrinsic conductivity than equivalent bare copper. For electrical sizing, use the specified conductor resistance and application requirements.

The aluminum and tinned-copper shield layers are intended to reduce the impact of electrical noise on properly terminated control or signal circuits. Actual shielding effectiveness also depends on cable routing, shield coverage, connector construction and grounding practice.
Shielding is not a substitute for protective earth, correct circuit separation, adequate insulation or an electrical safety assessment.
Discuss Shielding and Cable Requirements
Typical evaluation areas include CNC controller interconnections, sensors, electronic instruments, equipment cabinets, electrical appliances and selected low-voltage control circuits. This product should be specified only where the conductor size, voltage and temperature ratings meet the actual electrical design.

Industrial customers can share a wiring diagram or application description for compatibility review. Applications near high-noise machinery may benefit from appropriate shielding, separation from motor power cables and verified connector termination practices.
For cable purchasing, provide the required length, quantity, connector or termination details, the installation environment and any required certificates or test reports. Custom conductor colors, cutting lengths or packing arrangements can be discussed during quotation.

Contact Zhong Hua Jiang for Distributor Supply

Buyers requiring UL Style 2464, RoHS declarations or other market-specific documentation should request the certificate, UL file or product marking that applies to the exact cable construction supplied. Style names and promotional artwork alone are not sufficient to establish approval for every cable configuration.

For distributor evaluations and project purchases, request product-specific technical documents, production details and references relevant to the required order specification.
20/6 identifies six conductors, each nominally 20 AWG. The listed product combines six color-coded, stranded tinned-copper conductors inside a PVC jacket with two shielding layers.
The stated ratings are 300V and 80°C (176°F). Electrical suitability depends on conductor loading, installation and the applicable machine or wiring standard.
The listed finished jacket diameter is 7.5 ± 0.15mm. Confirm connector gland, bend-space and cable-clamp compatibility against this measurement.
The six listed insulation colors are black, red, yellow, white, green and orange. Installation teams should verify conductor assignment using the machine wiring diagram.
The conductors are listed as tinned stranded copper. The insulation and outer jacket are PVC, while the shielding construction includes aluminum and tinned copper.
Aluminum and tinned-copper shielding may reduce electromagnetic interference affecting properly installed signal and control circuits. Routing, grounding and connector terminations influence actual performance.
It may be considered for suitable control and interconnection circuits when the electrical requirements are met. Do not assume that a 300V, 20AWG shielded cable is suitable for the VFD-to-spindle power connection without a separate engineering assessment.
Repeated-flex suitability is not established by the specifications on this page. For moving cable carriers, request a cable specifically rated for the required bending radius, flex cycle and installation conditions.
Yes, those are the stated ratings in the product specification. Check the cable marking, relevant approvals and the temperature of the actual installation before use.
The product specification states 36.7 Ω/km at 20°C. For longer runs, calculate voltage drop and electrical losses using the actual circuit current and full conductor path length.
The technical table gives “10MΩ/KM 20°C” for insulation resistance and “2000AC V/min” for the dielectric test. Ask for the manufacturer’s data sheet to verify test notation and methods before relying on them.
The product listing references UL2464, an appliance-wiring-material style. Buyers should request the specific UL file number, cable marking and applicable approval documents to verify the supplied product.
The specification identifies the insulation and jacket materials as PVC (RoHS). For compliance-controlled projects, request a current product-specific material declaration or test documentation.
Tin plating is used mainly for surface protection and solderability. It does not by itself mean the conductor is more conductive than an equivalent bare-copper conductor; compare published resistance data.
The product listing includes a length range of 5m–5000m. Confirm the available cut lengths, reel options, minimum order quantity and packing details for your order.
Customers can inquire about custom conductor colors, cable lengths, labeling, packing or related specifications. Final feasibility and order terms should be confirmed in the quotation.
Provide the 20AWG six-core specification, required cable length and quantity, destination, wiring application, any certification requirements, and whether connectors or custom packing are needed.
Follow the equipment manufacturer’s grounding and shielding design. Shield termination depends on the installation, connector type and interference conditions; protective earth requirements must be met separately.
