(3) Material and Style

The materials and styles of H05V-K and H07V-K cables are carefully selected to ensure performance, durability, and ease of installation.

Conductor Material: The conductors are made of electrolytic copper with a purity of 99.9% or higher. This high purity ensures excellent electrical conductivity (≥58 MS/m), minimizing energy loss during transmission. Copper’s malleability allows for easy shaping during installation, while its high melting point (1083°C) enhances safety in case of overheating. The solid conductor is extruded as a single piece, providing rigidity, while the Stranded Conductor is formed by twisting multiple fine Copper Wires, offering flexibility.

Insulation Material: The insulation is made of flame-retardant PVC (polyvinyl chloride) compound. This material is chosen for its exceptional insulating properties, Chemical Resistance, and cost-effectiveness. The PVC is blended with additives such as antimony trioxide (flame retardant), plasticizers (for flexibility), and stabilizers (to resist heat and UV degradation). These additives ensure the insulation remains durable in harsh environments, resisting moisture, oil, and abrasion.

Color Coding: The PVC insulation features standardized color coding for easy identification:

Live conductors: Brown or black

Neutral conductors: Blue

Earth conductors: Green-yellow striped (where applicable)

This color coding adheres to IEC 60446, simplifying installation and reducing the risk of wiring errors, which is critical for electrical safety.

Cable Styles: The cables are available in two main styles:

Solid core: Best for fixed installations where rigidity is needed, such as in conduits or behind walls.

Stranded Core: Ideal for applications requiring flexibility, such as in tight corners, movable fixtures, or renovation projects.

Both styles have a smooth, cylindrical outer surface, allowing easy pulling through conduits and reducing friction during installation.

(4) Production Process

The production of H05V-K and H07V-K cables involves rigorous processes to ensure quality and compliance with international standards.

Copper Conductor Manufacturing:

Melting and Casting: High-purity copper cathodes are melted in a furnace under controlled conditions to avoid impurities. The molten copper is cast into continuous rods (8-12mm diameter) using a vertical casting machine.

Wire Drawing: The copper rods are drawn through a series of diamond dies with progressively smaller openings to reduce their diameter to the required size for the conductor. This process is done in a wire drawing machine with lubrication to prevent overheating and ensure a smooth surface.

Annealing: The drawn copper wires are annealed in a controlled-atmosphere furnace (nitrogen or hydrogen) at 300-500°C. Annealing softens the copper, improving its ductility and conductivity, which is crucial for forming solid or Stranded Conductors.

Stranding (for stranded conductors): Multiple annealed wires are twisted together in a stranding machine at a precise lay length (the distance over which one strand completes a full twist). This ensures uniform flexibility and strength.

Insulation Extrusion:

PVC Compounding: PVC resin is mixed with flame retardants, plasticizers, stabilizers, and colorants in a mixer to form a homogeneous compound. The compound is then pelletized for easy handling.

Extrusion: The copper conductor is fed into an extrusion machine, where the PVC compound is melted and extruded around the conductor to form a uniform insulation layer. The extrusion die is designed to ensure precise insulation thickness and concentricity (alignment with the conductor).

Cooling and Sizing: The Insulated Conductor is cooled in a water bath to solidify the PVC. It then passes through a sizing die to ensure the insulation meets the required diameter specifications.

Quality Testing:

Conductor Tests: Conductivity (using a micro-ohmmeter), tensile strength, and elongation tests are performed to verify the copper’s quality.

Insulation Tests: Insulation resistance (using a megohmmeter), dielectric strength (high-voltage testing), and flame retardancy (vertical burning test) are conducted.

Dimensional Checks: The overall diameter, insulation thickness, and conductor size are measured to ensure compliance with specifications.

Spooling and Packaging:

The finished cables are spooled onto plastic or wooden reels of various sizes (100m, 250m, 500m) using an automatic spooling machine. This ensures neat winding and easy handling during transportation and installation.
