Overview
UHCCY solar cables provide reliable DC connections for photovoltaic systems, with multiple cable sizes, colors, reel lengths, and OEM options available.
Solar cable provides the electrical connection between photovoltaic modules and other DC components within a PV system.
Unlike general indoor electrical wire, photovoltaic cable can be exposed for long periods to sunlight, temperature changes, moisture, mechanical stress, and outdoor environmental conditions. Cable construction, insulation, sheath materials, voltage rating, conductor size, and installation conditions therefore need to be considered together.
UHCCY supplies solar cable for photovoltaic string wiring, array connections, combiner boxes, inverter DC inputs, and other PV power transmission applications.
Rather than treating every cable size and color as a separate product, UHCCY solar cable is supplied as a configurable product family, allowing customers to select the appropriate conductor cross-section, color, reel length, standard, and packaging according to project requirements.
A typical photovoltaic cable consists of:
Conductor
Flexible stranded conductor for electrical current transmission.
Insulation
Electrical insulation surrounding the conductor.
Outer Sheath
Protective outer layer designed according to the applicable cable construction and environmental requirements.
For standard European-type photovoltaic cable, H1Z2Z2-K is a widely used designation for flexible, single-core, cross-linked photovoltaic cable.
EN 50618 applies to low-smoke, halogen-free, flexible, single-core PV power cables with cross-linked insulation and sheath for DC systems up to 1.5 kV.
IEC 62930 likewise covers single-core cross-linked insulated PV cables for systems with rated voltages up to and including 1.5 kV DC.
These two terms describe different characteristics of the cable.
A single-core cable contains one electrical conductor path inside the cable.
A stranded conductor means that the conductor itself consists of multiple smaller wires rather than one solid metal conductor.
Standard flexible PV cable therefore commonly combines:
Single-core cable + stranded conductor
This structure provides the flexibility required for routing and termination in photovoltaic installations.
If UHCCY later offers twin-core or other special cable constructions, these can be added as separate selectable configurations.
Solar cable is typically required in substantial lengths rather than as individual short products.
UHCCY can therefore supply cable by complete:
depending on cable size and order quantity.
This supply format is particularly suitable for:
Custom reel length, packaging, cable marking, and private-label requirements can be discussed during quotation.

Selection Guide
The required cable construction and certification may depend on the destination market and project specification.
Common photovoltaic cable requirements include:
Certification should always be verified against the exact cable supplied.
Cable cross-section should be selected according to:
Common photovoltaic cable cross-sections include:
2.5 mm² / 4 mm² / 6 mm² / 10 mm²
but the correct size must be calculated for the actual installation.
Do not select cable size solely based on inverter or module power.
The cable voltage rating must be suitable for the maximum PV system voltage.
For modern high-voltage solar arrays, suitable cable configurations are available for systems up to 1500V DC.
Cable compatibility with the PV connector is determined by more than conductor cross-section.
Check both:
against the connector terminal and cable gland specifications.
A 6 mm² cable should not automatically be assumed compatible with every connector labelled for 6 mm² cable.
Black and red are commonly used to assist DC circuit identification.
Final color selection should follow project specifications and applicable local wiring practices.
OEM cable colors may be available depending on order quantity.
For wholesale and project orders, select the required:
Custom cable marking and private-label packaging can also be specified during quotation.
Use Cases
DC cable connections between rooftop PV modules, strings, isolators, and residential solar inverters.
Solar cable for larger rooftop and ground-mounted commercial photovoltaic systems requiring longer string and array wiring.

Connections between PV modules, string circuits, combiner equipment, and inverter DC inputs.
Installation
Select the cable cross-section according to current, voltage drop, cable length, ambient temperature, installation method, and applicable electrical requirements.
Verify that the cable voltage rating is suitable for the maximum DC voltage of the photovoltaic system.
Use PV connectors that are compatible with both the cable conductor cross-section and finished cable outer diameter.
Use appropriate photovoltaic cable cutters, stripping tools, and crimping tools when preparing connector terminations.
Avoid damaging conductor strands when removing cable insulation.
Observe the minimum bending radius specified for the actual cable during routing and installation.
Avoid excessive pulling force, sharp edges, crushing, and unnecessary mechanical stress.
Secure cable routing to prevent prolonged abrasion or contact with unsuitable surfaces.
Where cables are exposed outdoors, use products and installation methods suitable for the expected UV, moisture, temperature, and environmental conditions.
Maintain correct DC polarity and follow applicable project identification requirements.
Electrical installation and termination should be carried out according to the applicable system design, connector instructions, and local electrical requirements.

The main difference is conductor cross-sectional area.
A larger cross-section generally provides lower electrical resistance and may support greater current or reduce voltage drop, but the correct size depends on circuit current, cable length, installation conditions, temperature, and applicable electrical requirements.
Standard photovoltaic cable such as common H1Z2Z2-K cable is typically single-core.
However, the conductor inside the cable is normally flexible and consists of multiple strands.
Therefore, single-core cable does not mean solid single-strand conductor.
Yes, provided that the cable conductor cross-section and finished outer diameter fall within the allowable range of the specific connector.
Both the connector contact and sealing gland compatibility should be checked before assembly.
Calculate the required size according to operating current, allowable voltage drop, circuit length, ambient temperature, cable grouping, installation method, and applicable regulations.
Common 4 mm² or 6 mm² sizes should not be selected solely because they are widely used.
Solar cables designed and rated according to applicable 1500V DC photovoltaic cable requirements can be used in corresponding systems.
