Zhong Hua Jiang 18AWG 2-conductor double-shielded cable combines two twisted tinned-stranded copper conductors, PVC insulation, an aluminum shielding layer and tinned-copper shielding. With a 300V rating, 80°C temperature rating and 5.7 ± 0.15mm outer diameter, this 18/2 cable is designed for compatible signal, control and auxiliary equipment wiring.
The foil-and-copper shielding construction can help reduce unwanted electromagnetic coupling when the shield is correctly terminated. Its red and black insulated conductors simplify circuit identification in machinery, instrumentation, control cabinets and automation equipment.

The two insulated 18AWG conductors are twisted together inside a PVC jacket. Tinned stranded copper supports solderability and oxidation resistance, while the aluminum and tinned-copper shielding layers help control interference in electrically noisy installations. Actual shielding performance depends on the complete cable assembly and termination.
For a cable specification review, provide the required length, cable routing, connector or termination details, operating voltage, signal type and installation environment. Different conductor and jacket configurations can be discussed for OEM projects.
This 18AWG two-core shielded cable is suitable for industrial buyers seeking a clearly defined conductor count, material construction, rated voltage and outer diameter. It can be considered for sensor circuits, electronic instrumentation, CNC accessory wiring and other compatible low-voltage control connections.
Compared with an unshielded two-core cable, the added foil and copper shielding layers can reduce susceptibility to electromagnetic interference near controllers, transformers and motor equipment, provided the installation uses appropriate separation and shield termination practices.
Equipment manufacturers, panel builders, maintenance teams and distributors can use the published technical specifications to check cable suitability and request additional documentation before ordering.

Tinned Copper Conductors for Reliable Termination
Tin Plating Helps Limit Surface Oxidation
Stranded Construction Supports Practical Cable Routing
Aluminum and tinned-copper shielding work together to help limit electromagnetic interference in compatible signal and control cable assemblies.
Effective shielding depends on the type of interference, the cable routing and the termination of the shield at the equipment.
The cable shield is intended for electromagnetic compatibility and is not a substitute for a properly sized protective earth conductor. Follow the equipment manufacturer’s grounding instructions and applicable electrical codes.

It is a cable containing two insulated 18AWG conductors with two shielding layers around the core group. The published construction for this version uses tinned stranded copper, PVC insulation and jacket materials, plus aluminum and tinned-copper shielding.
18 indicates the American Wire Gauge size of each conductor, while 2 indicates two insulated cores. The published core colors for this version are red and black.
The published ratings are 300V and 80°C (176°F). Cable approval for a machine depends on the full electrical circuit, applicable wiring requirements and installation environment.
The published jacket outside diameter is 5.7 ± 0.15mm. Include this tolerance when selecting cable glands, connectors or protective conduit.
It uses tinned stranded copper. The tin plating supports soldering and helps resist surface oxidation; the strand construction helps with practical routing during installation.
The original product specification lists 26.7 Ω/km at 20°C. Confirm the conductor construction and resistance test report when calculating voltage drop for a specified cable run.
The two shield layers help reduce coupling of electromagnetic interference into the conductors. Effectiveness depends on proper shield connection, cable layout and the frequency of the interference.
No. Cable shielding is an electromagnetic compatibility measure; it is not a substitute for a dedicated protective earth conductor when the installation requires one.
It may be used for compatible CNC auxiliary signal, sensor or control connections when circuit requirements match the cable rating. Verify the signal type, wiring diagram, grounding and operating environment first.
Not automatically. VFD motor output cables must be selected for the motor voltage, current, number of conductors, insulation properties, grounding and drive manufacturer recommendations. This 2-core product should not be assumed suitable for spindle power connections.
The shielding may help reduce noise pickup, but good wiring practice is still essential. Keep sensitive signal wiring suitably separated from high-current power cables and terminate shields according to the machine design.
Use for power only when voltage, current, conductor heating, protective devices and installation rules are all compatible. Its 300V marking does not by itself establish an allowable current.
The product is described as flexible wire, but the provided specification does not establish a continuous-flex rating or validated bend-cycle life. For repeated movement, request a cable specifically rated for the intended cable carrier.
18AWG has a larger nominal conductor cross-section than 20AWG. Compare the actual conductor resistance, cable diameter and current requirements before selecting a cable for a given installation.
The product title references UL2464. Buyers who require UL-recognized appliance wiring material should verify the exact product marking, manufacturer identification and applicable UL Product iQ record.
The original specification identifies the PVC insulation and jacket as RoHS. For regulated projects, obtain a current material declaration for the exact cable and production version.
The original table lists 2000AC V/min. For technical evaluation, request the detailed test method and duration rather than interpreting this abbreviated entry as a complete test specification.
Choose length based on equipment routing, service loops, voltage drop and termination method. Include required length and any cable assembly drawings when requesting a quotation.
The company states that buyers may discuss changes to length, conductor configuration, shielding, jacket and packaging. Feasibility and order conditions should be confirmed for the requested version.
Send the 18AWG 2-core cable specification, target quantity, requested length, application, destination and any required documents to Zhong Hua Jiang for a project quotation.
