LION Building Wire – The Safe Solution for Residential Electrical Systems
During residential construction, the residential electrical system is always a critical component, directly impacting long-term safety and operational efficiency. Choosing the right building wire not only ensures stable system operation but also minimizes potential risks during usage.

LION building wire is a premium product manufactured by DAPHACO – a brand with over 27 years of experience in the electrical wire and cable industry. Featuring standardized structures, high-quality materials, and a diverse product range, it fully satisfies all requirements for residential construction projects.
General Structure of Building Wire
Fundamentally, all types of building wires consist of two main components:
- Conductor Core: Made of 100% pure copper, available as a solid single strand, a 7-strand stranded core, or multiple fine wires (Class 5) to maximize flexibility.
- Insulation Layer: Made of PVC, designed to insulate, prevent current leakage, and protect the conductive core.
Depending on the specific application within the residential electrical system, wires are engineered in various configurations, such as 7-strand cables, flexible single-core wires, twin-parallel wires, round cables, or flat (oval) cables.
Popular Types of LION Building Wires
1. LION CV – 7-Strand Single-Core Electrical Cable
This is a highly popular 7-strand cable used in residential electrical systems. It features a conductor core made of 7 concentric stranded copper wires insulated with PVC.
- Maximum conductor temperature: 75°C.
- Characteristics: Moderate rigidity, making it ideal for conduit installation inside walls (concealed wiring).
- Common Applications:
- Concealed in-wall electrical conduits.
- Socket systems and main power supply lines.

2. LION VCm – Flexible Single-Core Wire
The flexible single-core product line features a single flexible copper conductor core (Class 5), composed of multiple fine strands to enhance bending capability and installation flexibility.
- Insulation: PVC
- Operating Temperature:
- According to TCVN 6610-3: 70°C
- According to AS/NZS 5000.1: 75°C
- Common Applications:
- Connecting electrical appliances.

3. LION VCmd – Flexible Twin-Parallel Wire
Flexible twin wire consisting of two parallel cores made of Class 5 flexible copper conductors, insulated with PVC
- Characteristics: Neat design, easy to install.
- Optimization: Highly optimized for standard household electrical appliances.
- Common Applications:
- Lighting systems.
- Power outlets and light switches.

4. LION VCmo – Flexible Oval Cable
The oval cable series features a flat design with two flexible copper cores (Class 5), protected by individual PVC insulation and an outer PVC sheath.
- Characteristics:
- Easy to install as surface-mounted wiring
- Enhancing aesthetic appeal.
- Common Applications:
- Surface-mounted wiring on walls or ceilings.
- Interior furniture electrical systems.

5. LION VVCm – Flexible Round Cable
This is a round, multi-core sheathed cable containing 2 to 5 flexible copper cores (Class 5), protected by individual PVC insulation and an outer PVC sheath.
- Characteristics: Robust structure, high mechanical strength, and excellent resistance to environmental impacts.
- Common Applications:
- Outdoor areas.
- Systems requiring high durability.
- Medium-power household appliances.
