4mm 6mm Pv Cable

CNKA4mm 6mm pv cable Introduction

China Factory CNKA offers Easy-Maintainable Advanced 4mm and 6mm PV cables designed for outdoor environments. These specialized photovoltaic cables undergo irradiation crosslinking, where high-energy electron beams alter the molecular structure of the insulating material from linear to a three-dimensional network. This process enhances the temperature resistance of the cables. Compared to non-crosslinked cables, irradiated crosslinked cables can withstand temperatures up to 90°C, 105°C, 125°C, 135°C, or even 150°C, and exhibit a 15-50% increase in load-bearing capacity. These cables are highly durable, capable of withstanding severe temperature fluctuations and chemical erosion, making them suitable for outdoor use for over 25 years.

CNKA4mm 6mm pv cable Wiring Techniques

Photovoltaic System Wiring Guidelines

1.DC and AC Wiring Separation:

-DC Circuit: Connects photovoltaic panels to the DC distribution components.

-AC Circuit: Connects the inverter to the power grid.

2.Cable Management:

-In large and medium-sized photovoltaic power plants, numerous DC cables are used.

-Label each cable with a wire number for ease of maintenance.

-Separate strong power lines from weak power lines.

-Route signal lines (e.g., 485 communication) separately to avoid interference.

3.Wiring Installation:

-Use conduits and cable trays to protect and organize cables.

-Minimize the exposure of wires to external elements.

-Maintain clean, horizontal, and vertical wiring paths.

-Avoid cable joints inside conduits and trays to simplify maintenance.

4.Special Considerations:

-If replacing copper wires with aluminum wires, use reliable copper-aluminum adapter terminals to ensure proper connection.
