Standard Fixed Installation Wire

This single solid wire is manufactured by Jiangsu Jingwei. We have been producing cables for 39 years. This product is a standard solid-conductor building wire available in a full range of sizes. It uses a single solid copper core. The size range is from 1.5 mm² to 400 mm². Insulation thickness ranges from 0.7 mm to 2.6 mm, and outer diameter ranges from 3.2 mm to 33.2 mm. The weight ranges from 19 kg/km to 3828 kg/km. This single solid wire is one of the most commonly used building wires.

High-Purity Copper and Reliable Insulation

The conductor is made of high-purity solid copper, offering low resistance, stable conductivity, and efficient heat dissipation. The insulation layer is uniform and dense, providing strong resistance to voltage stress, moisture, and dielectric breakdown. This single solid wire complies with IEC 60502 and relevant national standards. Electrical resistance, outer diameter, insulation performance, and voltage ratings are all standardized. It is fully compatible with switches, terminals, and distribution boxes.

Neat and Durable for Building Applications

Once installed, the wire remains stable without vibration, deformation, or loosening. Its structure is firm, keeping wiring straight and orderly. It is suitable for fixed power distribution and control wiring in residential, commercial, and industrial buildings. This single solid wire offers strong resistance to aging, moisture, and fire. It operates reliably for long periods without overheating or failure. The failure rate is very low. It is widely used for residential wiring and fixed industrial installations as a classic and cost-effective insulated solid wire solution.
