A solar farm spreads across hundreds of hectares. A wind farm stretches over kilometres of ridge line. The equipment that generates the power — panels, inverters, turbines — gets all the attention, but the cables that connect them carry the same current, cover the same distance, and often determine whether a project delivers its rated output or falls short.
Zhongdong Cable supplies medium-voltage collection cables and photovoltaic wiring for solar and wind projects across export markets. Our 35 kV XLPE cables are used in wind farm collector networks and large-scale solar inverter-to-substation connections, with insulation rated for partial discharge and thermal limits under outdoor, above-ground, and trenched installation conditions. For photovoltaic arrays, we manufacture PV cables with UV-stabilized sheaths and halogen-free insulation, tested to EN 50618 and IEC 62930, with a rated service life of 25 years under continuous outdoor exposure.
All cables are supplied with UV resistance, thermal endurance up to 90°C continuous (120°C emergency), and flame retardancy to IEC 60332-1 or IEC 60332-3 as required by project fire safety classifications.
Manufacturing follows IEC 60502 (MV power cables up to 35 kV), EN 50618 (PV cables), and IEC 62930 (photovoltaic wiring), with H1Z2Z2-K and PV1-F configurations available. Per-batch test records are kept from conductor stranding to final hipot test.
35 kV collector networks — XLPE cables from inverter stations to substation step-up transformers
Photovoltaic array wiring — DC cables between panels, combiners, and inverters
Wind farm power transmission — medium-voltage cables from turbine bases to grid collection points
Inverter and combiner box connections — flexible PV cables with halogen-free flame-retardant insulation
Substation-to-grid tie-ins — MV cables for final connection to utility networks
Options include conductor material (aluminum or copper), armouring (steel tape, aluminum wire, or non-metallic), sheathing compounds (UV-stabilized, flame-retardant, anti-termite), and drum lengths. Engineering data and partial discharge test reports are supplied with project quotes.
PV1-F Solar Cable 1.5kV DC
The PV1-F solar cable manufactured by Zhongdong Cable is a flexible photovoltaic cable designed for solar power generation systems, providing reliable DC power transmission between photovoltaic modules, inverters, combiner boxes, and other solar equipment.
The cable adopts a tinned copper conductor, cross-linked polyolefin insulation, and cross-linked polyolefin outer sheath, offering excellent resistance to UV radiation, ozone, moisture, and temperature variations. Its flexible structure allows easy installation in complex photovoltaic layouts.
PV1-F cable is widely used in rooftop solar systems, ground-mounted PV plants, and other renewable energy projects where long-term outdoor durability and electrical reliability are required.
H1Z2Z2-K Solar Cable 1.5/1.8kV DC
The H1Z2Z2-K solar cable manufactured by Zhongdong Cable is a flexible photovoltaic cable designed for solar power generation systems, including utility-scale PV plants, rooftop solar installations, and energy storage applications.
The cable is constructed with a tinned copper conductor, halogen-free cross-linked polyolefin insulation, and halogen-free cross-linked polyolefin outer sheath. It provides excellent resistance to UV radiation, ozone, moisture, and extreme weather conditions, ensuring reliable long-term operation in outdoor photovoltaic environments.
Compared with conventional PVC cables, H1Z2Z2-K features a halogen-free and flame-retardant construction, reducing toxic gas emissions during fire conditions and meeting the safety requirements of modern solar energy projects.
CU/XLPE/CWS/SWA/PVC Three Core Power Cable 26/35kV
The CU/XLPE/CWS/SWA/PVC three-core power cable 26/35kV manufactured by Zhongdong Cable is designed in accordance with IEC 60502-2 and IEC 60228 (Class 1 or Class 2 copper conductor). It adopts copper conductors, XLPE insulation, copper wire screen (CWS), steel wire armour (SWA), and PVC outer sheath, providing a reliable solution for high medium-voltage underground distribution systems.
At 26/35kV level, the cable is mainly used in primary distribution networks where higher insulation performance and stronger mechanical protection are required.
AL/XLPE/CTS/SWA/PVC Three Core Power Cable 8.7/15kV
The AL/XLPE/CTS/SWA/PVC three-core power cable 8.7/15kV manufactured by Zhongdong Cable is designed in accordance with IEC 60502-2 and IEC 60228 (Class 1 or Class 2 aluminium conductor). It uses aluminium conductors, XLPE insulation, copper wire screen (CTS), steel wire armour (SWA), and PVC outer sheath, providing a cost-efficient solution for medium-voltage underground distribution systems with strong mechanical protection.
The SWA structure improves tensile strength, making the cable suitable for long pulling routes and underground installations where higher mechanical stress may occur.
Zhongdong Cable combines premium raw materials, large-scale manufacturing capabilities, and strict quality control systems to deliver cable products that fully match your technical requirements and brand identity.
