Residential cables — including building wires (BV, BVR) and power cords (RVV, RVVP) — are among the most widely used cables in electrical installations. They are used in homes, factories, appliances, and public infrastructure — making quality, safety, and reliability essential. Reliable and efficient production equipment is the foundation of cable quality and productivity.
For over 20 years, Hongkai has specialized in complete production solutions for residential cables, covering key equipment such as copper wire drawing machines, annealing and tinning machines, extruders, cabling machines, and automatic coiling machines. We help customers manufacture high-quality cables that comply with global standards and certifications such as UL, VDE, and CCC — while reducing operating costs and improving process stability..
Key Equipment in a Residential Cable Production Line
1. Conductor Pre-treatment: Drawing and Annealing
Residential cable conductors are typically made of copper. We offer high-speed fine wire drawing machines and intermediate continuous annealing machines, capable of continuously drawing 8 mm copper rod down to the required wire sizes (e.g., 0.5mm², 1.5mm², 2.5mm², etc.) with inline annealing, ensuring a soft conductor with low electrical resistance and excellent oxidation resistance..
2. Insulation Extrusion: The Core of the Wire “Jacket”
The plastic extruder is the heart of a residential cable production line. Our φ30–φ90 single-screw extruders are specially designed for insulation materials such as PVC, PE, and XLPE. Precision temperature control and automatic diameter feedback ensure…, they ensure uniform insulation thickness and high concentricity, meeting voltage withstand and flame-retardant requirements. For BVR flexible wires, we also offer double-layer co-extrusion technology to complete insulation and sheathing extrusion in a single pass, significantly boosting production efficiency..
3. Cabling and Filling: Integration of Multiple Cores
For power cords (e.g., RVV 2×1.5, 3×2.5), multiple insulated cores need to be stranded together. Our cantilever single-twist cabling machines and cage-type cabling machines precisely control the lay length while synchronously filling cotton yarn or PP filler cords, ensuring a compact, round cable core for the sheathing process..
4. Outer Sheath and Coiling: The Final Step for Finished Products
Sheathing extrusion uses larger extruders of φ70–φ120, including cooling troughs, an inkjet printer, and capstan take-up units. The finished cable then passes through an automatic coiling machine or reel winder, where it is automatically wound, bundled, and film-wrapped, ready for packaging while significantly reducing labor requirements.
