The QUADRIOS 19011CA090 is a comprehensive PVC-stranded wires kit designed for internal wiring of electrical devices, control panel installations, prototyping, and electronics workbench applications. This 7-color wire assortment provides the essential conductor types needed for most electrical and electronic projects in a single convenient package.

Conductor Construction: Each wire features a high-quality stranded copper conductor constructed from bright annealed copper for optimal electrical conductivity. The multi-strand construction provides excellent flexibility compared to solid-core wires, making these wires ideal for applications requiring repeated bending, routing through confined spaces, or connections subject to vibration. The 1.5 mm² cross-section (approximately 16 AWG) strikes an optimal balance between current-carrying capacity and handling convenience, supporting moderate power distribution and signal applications.

Insulation Material: The PVC (Polyvinyl Chloride) insulation provides reliable electrical isolation with good dielectric properties and mechanical protection. The insulation material meets standard flame retardancy requirements and maintains its physical properties across the full operating temperature range of 0°C to 80°C. The nominal outer diameter of 2.7 mm per wire allows for dense packing in cable bundles, conduit systems, and terminal blocks while remaining easy to strip and terminate.

Electrical Ratings: Rated for 300V continuous operation with a 2kV test voltage, these wires are suitable for low-voltage electrical systems, control circuits, and electronic equipment internal wiring. The stranded copper conductor ensures low DC resistance, minimizing voltage drop over moderate distances and reducing heat generation under load. The insulation thickness provides adequate creepage and clearance distances for standard low-voltage applications.

Color Coding System: The kit includes seven distinct colors - black, white, red, blue, brown, gray, and green-yellow - enabling systematic circuit identification and simplified troubleshooting. The green-yellow wire is specifically designated for protective earth (PE/ground) connections, complying with international wiring color standards. This comprehensive color assortment supports multi-conductor projects, control panel wiring, and color-coded signal routing without requiring additional color-specific purchases.

Compliance and Environmental: The 19011CA090 kit is RoHS compliant, confirming the absence of restricted hazardous substances including lead, mercury, cadmium, and hexavalent chromium. The product is also SVHC free (Substances of Very High Concern), ensuring compliance with REACH regulations. While halogen-free is not applicable to this PVC-insulated product, the materials used meet standard environmental requirements for general-purpose electrical wiring. Country of origin is China (CN), with customs tariff number 85444995 for international trade classification.

Application Scenarios: This wire kit is exceptionally well-suited for a wide range of applications including internal wiring of industrial control panels, distribution boards and switchgear assemblies, prototyping and breadboard projects, electronics laboratory workstations, hobbyist and maker projects, model building and RC equipment wiring, automotive and marine accessory installations, repair and maintenance of electrical equipment, educational and training environments, and small-scale production wiring harnesses.

Handling and Installation: The stranded construction requires appropriate termination techniques for optimal results. Use of pin terminals, bootlace ferrules, or tinning with solder is recommended when terminating into screw-type terminal blocks to prevent strand fraying and ensure reliable connections. For crimp connections, use correctly sized terminals matched to 1.5 mm² conductors. The PVC insulation can be stripped using standard wire strippers set to 1.5 mm² (16 AWG) settings. Avoid excessive pulling tension during installation, and maintain minimum bend radii of approximately 5-6 times the outer diameter to prevent insulation damage.

Comparison to Alternatives: Unlike purchasing individual wire rolls of each color, this pre-assembled 7-color kit provides cost efficiency and convenience by delivering exactly the color assortment needed for standard wiring projects. The stranded construction offers superior flexibility compared to solid H07V-U wires, making routing in tight spaces significantly easier. While PVC insulation does not offer the high-temperature performance of silicone (typically 200°C) or the flame resistance of LSZH materials, it provides an excellent balance of electrical properties, mechanical durability, and cost-effectiveness for the majority of general-purpose wiring applications.
