Solar Cables Manufacturers

Our Position in the New Energy Cable Category

Henghui Cable is a China cable manufacturer specialising in the research, development, production and sales of wires and cables, with power cables up to 110 kV and below in our overall portfolio. Within the new energy segment we focus on the DC-side and auxiliary circuits that carry power from modules to combiner boxes, inverters and storage interfaces.

Our new energy cable range is engineered for outdoor and indoor fixed installation in systems that face continuous UV radiation, wide diurnal temperature swings, wind-driven rain and salt-laden air. The three solar photovoltaic cable families we supply cover the main international approval routes used by EPC contractors and module suppliers.

Solar Photovoltaic Cable Range

Each family shares the same conductor and insulation architecture, so the selection decision is driven by the standard required by the project specification and the DC voltage level of the array.

Construction and Material Selection

All three families use a Class 5 tinned copper conductor for flexibility and corrosion resistance at the termination, with cross-linked polyolefin insulation and a cross-linked polyolefin outer sheath. Low-smoke halogen-free tape is applied as an isolation layer where the construction calls for it.

• Conductor: Class 5 tinned copper, single core, 1.5–35 mm².
• Insulation and sheath: cross-linked polyolefin, halogen-free.
• Core identification: black, red or white insulation, or to customer requirement.
• Sheath colour: black as standard; red or other colours on request.
• Performance options: flame retardant A/B/C grade, low smoke and halogen-free, UV-resistant, cold-resistant, ozone-resistant and weather-resistant.

Operating Envelope and Installation Conditions

The thermal and mechanical limits below apply across our solar photovoltaic cable range and define how the cable behaves in the array layout, cable tray routing and combiner box entry.

Application Fit Across the New Energy Chain

Our photovoltaic cables transmit the DC power generated by PV panels and are widely used to interconnect photovoltaic modules and DC combiner boxes. The same construction serves other connections in photovoltaic systems or similar generation systems, indoors or outdoors, in fixed installation.

• Module-to-module and string wiring: single-core 1.5–35 mm² sizes cover the string current range and the voltage drop budget over long runs.
• String-to-combiner and combiner-to-inverter: higher cross-sections reduce DC resistance and resistive losses where cable runs are long.
• Rooftop and ground-mount arrays: UV-resistant, weather-resistant and cold-resistant sheathing for exposed routing.
• Utility-scale plants: the 1.5 kV DC rating of the EN and IEC versions supports higher string voltages and fewer series connections.

Configuration Options We Build To

Standard constructions cover most projects, and we produce both standardised and customised cables from customer drawings or samples. The variables we confirm before production are:

• Standard route: EN 50618, IEC 62930 or 2PfG 1169.
• Conductor cross-section from 1.5 mm² to 35 mm², single core.
• Insulation and sheath colour, including customer-specific identification.
• Flame retardant grade A, B or C, with low-smoke halogen-free performance.
• Additional resistance requirements such as UV, ozone, cold and weather resistance.
• Packing length, drum type and marking for site logistics.

Manufacturing, Quality Control and Compliance

Henghui Cable operates two production plants and nine specialised workshops, with an annual output exceeding 50,000 kilometres and an average monthly cable output of approximately 5,000 kilometres. Our quality management system, environmental management system and occupational health and safety management system have been certified since 2006.

Production is managed through a full MES environment, giving end-to-end digital control from raw material intake to finished product. Every metre is checked for electrical conductivity, insulation performance, mechanical strength and durability against the applicable standard. In 2025 we obtained TÜV Rheinland Solar PV Cable Certification, CE and EAC for our solar cable products.

Information We Use to Configure Your Solution

To prepare an accurate quotation and a production-ready specification, we work from the following project inputs. Where a project uses a standard construction, we confirm the model and specification directly; where it does not, we develop the cable against your drawing or sample.

Delivery, Warranty and After-Sales Support

Standard delivery time is approximately 7 to 10 days, supported by an ERP system and warehousing network. Our solar photovoltaic cables carry a one-year product warranty, and our after-sales team covers the full process from pre-delivery coordination to post-delivery follow-up, with regular customer satisfaction reviews.

For projects that also require the AC-side and grid connection scope, our wider portfolio includes Power Grid Transmission & Transformation Cables and Industrial Cables for control and instrumentation circuits.

Frequently Asked Questions

Which solar photovoltaic cable standard should a project specify?

The choice follows the approval route required by the project. EN 50618:2014 (H1Z2Z2-K) is common in European specifications, IEC 62930:2017 (62930 IEC 131) is used where IEC approval is required, and 2PfG 1169/08.2007 (PV1-F) is the TÜV route. All three are single-core, Class 5 tinned copper constructions with cross-linked polyolefin insulation and sheath.

What cross-sections and voltage ratings are available?

Our solar photovoltaic cables are supplied as single core from 1.5 mm² to 35 mm². The EN version is rated AC 1/1 kV and DC 1.5 kV, the IEC version DC 1.5 kV, and the TÜV version AC 0.6/1 kV and DC 1.8 kV.

Can you produce customised new energy cables?

Yes. We produce both standardised and customised cables, and we can develop products from customer drawings or samples. Customisation covers conductor size, insulation and sheath colour, flame retardant grade, and additional UV, ozone, cold or weather resistance requirements.

What is the minimum order quantity and delivery time?

Minimum order quantity varies by product, with most items starting at 200 metres. Standard delivery time is approximately 7 to 10 days.

What information do you need for an accurate quotation?

Provide the model, specification, quantity, technical specifications and any special requirements for the cable products. With those inputs we confirm the standard route, construction and packing, and issue a quotation against a production-ready specification.
