DC Solar Cable 1x6 mm²

Việt Hàn 1x6 mm² DC Solar Cable is a product in the field of solar cable / photovoltaic cable / DC power cable / tinned copper solar cable / XLPO insulated cable / solar power cable / DC conductor / tinned copper wire / XLPO insulated solar cable, manufactured and supplied by Viet Han High-Tech Manufacturing Joint Stock Company to solar power businesses, EPC contractors, M&E units, factories, energy project investors, and customers requiring specialized conductors for photovoltaic systems in Vietnam.
The product is used to transmit direct current between solar panels, junction boxes, string combiners, inverters, and related equipment in rooftop solar power systems, factories, commercial buildings, solar farms, and renewable energy projects.
According to published information, the cable has a nominal cross-section of 6 mm², Cu/XLPO/XLPO structure, a conductor made of multiple strands of tinned copper twisted in a bundle, insulation and outer sheath made of XLPO material, a working voltage up to approximately 1.5/1.5 kV DC, and a reference packaging of approximately 400 m/reel.
Viet Han does not apply a fixed solution for all systems. Cable selection is determined by project capacity, maximum current, string voltage, cable length, permissible voltage drop, ambient temperature, installation method, connector type, quantity, and acceptance requirements of each project.

1. Product Highlights

The cable has a 6 mm² cross-section, suitable for conductor runs requiring better current carrying capacity and power loss control compared to smaller cross-section cables under similar conditions.
The conductor is made of multiple strands of tinned copper twisted in a bundle, providing the cable with flexibility and bending capability suitable for wiring, connection, and arrangement within solar panel systems.
The tin coating on the copper wire surface helps limit oxidation, especially in environments with humidity, fluctuating temperatures, or outdoor installation conditions.
The multi-strand structure also facilitates connector crimping and installation in locations requiring bending or redirection of the cable within permissible limits.
The insulation and outer sheath use XLPO material, aiming for heat resistance, UV resistance, limiting the effects of ozone, humidity, and weather conditions.
The Cu/XLPO/XLPO structure forms two protective layers around the conductor. The inner insulation layer provides electrical isolation, while the outer sheath helps protect the cable from mechanical and environmental impacts.
According to the company's published information, the product can be used in DC power systems up to approximately 1.5/1.5 kV DC.
The cable can be supplied in black or orange, aiding in identifying conductor runs, polarity, or installation locations within the system.
Selection requires simultaneous consideration of current, voltage, cable length, temperature, correction factors, wiring method, voltage drop, and connector compatibility.

For EPC contractors, the product can be used for DC runs in photovoltaic systems after calculating current, cable length, and permissible voltage drop.
For factories and investors, the cable is suitable for rooftop solar power systems, contributing to the construction of DC power transmission lines between battery arrays and conversion equipment.
For replacement needs, customers need to check the current cable cross-section, system voltage, current, cable length, connector type, and applicable standards.

3. Consulting and Supply Process

The process may include:
- Receiving requirements and intended use.
- Determining the type of solar power system.
- Checking power, voltage, and current.
- Determining cable run length.
- Evaluating permissible voltage drop.
- Determining wiring method.
- Checking connector type and related equipment.
- Selecting cross-section, cable color, and reel specifications.
- Quoting and confirming delivery time.
- Supplying products and supporting technical information verification.
For new designs, customers should provide a system diagram, panel power, number of panels per string, open-circuit voltage, operating current, and distance to the inverter.
For replacement needs, it is necessary to provide images of the current cable, parameters on the cable sheath, cross-section, cable length, connector type, and installation conditions.
For recurring orders, the supply plan can be developed based on output, number of reels, construction progress, and delivery schedule of each project.

3.1. DC Solar Cable Selection Criteria

Cables are selected based on:
- System voltage.
- Operating current and maximum current.
- Conductor cross-section.
- Cable run length.
- Permissible voltage drop.
- Ambient temperature.
- Installation method.
- Number of cables run together.
- Outdoor conditions.
- UV exposure capability.
- Humidity, water, and ozone.
- Bending radius.
- Type of connector used.
- Project technical standards.
- Quantity and delivery time.
For long cable runs, resistance and voltage drop need to be calculated to limit power loss during transmission.
For rooftop or outdoor installed systems, surface temperature, ventilation capability, cable fastening methods, and distance to heat sources need to be considered.
If multiple cables are run together in a tray or conduit, appropriate correction factors must be applied to avoid reducing current carrying capacity.

3.2. Information Customers Need to Provide

Customers should provide:
- Type of solar power system.
- Total project capacity.
- Panel power and quantity.
- Number of panels per string.
- System DC voltage.
- Operating current and maximum current.
- Length of each cable run.
- Permissible voltage drop.
- Installation method.
- Indoor or outdoor environment.
- Type of connector and connection equipment.
- Required cable color.
- Reel specifications.
- Acceptance standards.
- Quantity and required delivery time.
The more complete the information, the more accurate the cross-section determination, voltage drop calculation, specification selection, and quotation generation will be.
If complete parameters are not available, customers can provide a system diagram, project images, panel and inverter catalogs for initial consideration.

3.3. Inspection and Storage Before Use

Before installation, it is necessary to check:
- Product name and cable cross-section.
- Information printed on the sheath surface.
- Cable color and reel specifications.
- Condition of the outer sheath.
- Whether the cable surface is scratched or deformed.
- Actual length and quantity.
- Type of connector supplied.
- System voltage and technical requirements.
- Technical documentation or certifications as per project requirements.
Cables should be stored in a clean, dry, well-ventilated place, away from water, oil, chemicals, heat sources, sharp objects, and prolonged direct sunlight before use.
Do not pull cables over sharp edges or apply excessive force. During installation, appropriate bending radius and pulling force must be observed.
Stripping, crimping terminals, or installing connectors must be performed using tools compatible with 6 mm² cables.
Before commissioning the system, polarity, connector tightness, insulation resistance, string voltage, and the condition of the entire cable run should be checked.
Cable runs need to be neatly secured, avoiding direct contact with high-temperature metal roofs, areas of standing water, or locations prone to impact.
