Photovoltaic Cable: Core Features for Solar Power Systems

Photovoltaic Cable (PV cable) is a specialized electrical cable designed exclusively for solar power systems, serving as the critical link between solar panels, inverters, combiner boxes, and other components. Tianhuan Cable’s photovoltaic cable is engineered with materials resistant to ultraviolet (UV) radiation, extreme temperatures, and moisture—key for outdoor solar installations exposed to harsh weather. Unlike regular wires, it is optimized for direct current (DC) applications, ensuring efficient power transmission in solar arrays.

Flexibility is another hallmark: the cable’s design allows easy routing during installation, even in tight spaces between panels or across rooftops. Durability is prioritized, with robust insulation and sheathing to withstand long-term exposure to environmental stressors, extending the lifespan of solar systems. Compliant with international standards, Tianhuan’s photovoltaic cable guarantees safety and reliability, making it indispensable for both residential and commercial solar projects.

EN 50618: European Standards for Photovoltaic Cable Performance

EN 50618 is a European standard that specifies requirements for photovoltaic cable used in solar power systems, ensuring consistency in performance, safety, and durability. Tianhuan Cable’s photovoltaic cable fully complies with EN 50618, covering critical parameters such as:

• Temperature resistance: The cable must operate reliably in a wide range (typically -40°C to +90°C), suitable for extreme climates.
• UV and weather resistance: Materials must resist degradation from sunlight, moisture, and ozone, ensuring longevity outdoors.
• Electrical performance: It mandates low resistance and high current-carrying capacity to minimize power loss in DC circuits.
• Mechanical strength: The cable must withstand bending, abrasion, and impact during installation and operation.

Adherence to EN 50618 ensures that Tianhuan’s photovoltaic cable meets strict European market requirements, making it a trusted choice for solar projects across the region.

IEC 50618: Global Standards for Uniform Photovoltaic Cable Quality

IEC 50618 is an international standard developed by the International Electrotechnical Commission (IEC) to unify specifications for photovoltaic cable worldwide. Complementing regional standards like EN 50618, IEC 50618 ensures that photovoltaic cable from Tianhuan Cable meets consistent quality benchmarks, regardless of the target market.

Key requirements under IEC 50618 include:

• Flame resistance: The cable must resist ignition and limit flame spread, enhancing safety in case of fire.
• Chemical resistance: It must withstand exposure to common environmental chemicals, such as those in agricultural or industrial areas.
• Long-term performance: Testing simulates 20+ years of outdoor exposure to validate durability—critical for solar systems with long lifespans.

By complying with IEC 50618, Tianhuan’s photovoltaic cable gains access to global markets, from Europe to Asia and beyond, ensuring customers worldwide receive cables of uniform quality.

H1Z2Z2 K 1x4mm²: A High-Performance Photovoltaic Cable Variant

H1Z2Z2 K 1x4mm² is a specialized photovoltaic cable model from Tianhuan Cable, designed for high-performance solar applications. The designation breaks down as follows:

• H1: Indicates suitability for harsh environments with high UV exposure.
• Z2Z2: Denotes flame resistance and low smoke emission, enhancing safety.
• K: Signifies flexibility, easing installation in complex setups.
• 1x4mm²: Specifies a single core with a conductor cross-sectional area of 4mm², suitable for medium-current solar circuits.

This model is rated for 1500V DC, making it ideal for larger solar arrays where higher voltage transmission is required. Its 4mm² conductor ensures efficient current flow with minimal loss, while the H1Z2Z2 properties guarantee resistance to UV, temperature extremes, and flames. H1Z2Z2 K 1x4mm² is TÜV-certified, validating compliance with EN 50618 Ve IEC 50618, and is widely used in commercial solar farms and industrial rooftop installations.
