Photovoltaic Cable

[ Product Overview ]

Photovoltaic cables are special cables used in solar photovoltaic power generation systems. They are mainly used for DC power transmission between photovoltaic modules and between modules and inverters. The products have excellent weather resistance, UV resistance, high and low temperature resistance and other characteristics, and are suitable for harsh outdoor environments.

Application Scenarios

In photovoltaic systems, PV1-F cables are recommended for inter-module connections. The typical specification is 4mm² and there are two colors, red and black, to distinguish the lines.

For the connection between the string and the combiner box, the H1Z2Z2-K cable is an ideal choice. Its typical specification is 6mm² and it has double insulation characteristics to ensure safe and stable connection.

For rooftop photovoltaic systems, it is recommended to use PV-WDZ type cables with flame-retardant 10mm² specifications to ensure power safety in complex rooftop environments.

In the construction of photovoltaic power stations, PV1-F type cables are also applicable, but 35mm² orange cables will be used to meet the larger current transmission requirements of the power station.

Different application locations are matched with cables of corresponding models and specifications according to their environment and transmission requirements, so as to ensure the efficient and safe operation of the photovoltaic system.

Selection Guide

Select by current

When the module current does not exceed 10A, it is recommended to use cables with a cross-section of 4mm². The maximum laying length of the cables can reach 100m to ensure stable current transmission.

If the module current is in the range of 10-15A, a cable with a cross-section of 6mm² is a suitable choice. At this time, the maximum cable length should be controlled within 80m to avoid excessive losses due to excessive line length.

When the module current is in the range of 15-20A, a cable with a cross-section of 10mm² should be used, and the maximum cable length is limited to 50m to ensure the safety and effectiveness of current transmission.

In general, the current of the components directly affects the selection of the recommended cable cross-section and the maximum laying length. Only reasonable matching can ensure the efficient operation of the circuit system.

Certification Standards

In the field of photovoltaic product certification, the TUV certification agency conducts UV resistance, high temperature resistance and other test items on products based on the 2 PfG 1169 standard to ensure the stability and reliability of the products in complex lighting and high temperature environments.

UL certification is based on the 4703 standard, focusing on testing the combustion performance of photovoltaic products to assess the safety of products in extreme situations such as fire.

CQC certification follows the GB/T 33594 standard and provides professional certification services for domestic photovoltaic products to ensure that the products meet the quality and safety requirements of the domestic market.

Different certification bodies rely on their own standards and testing items to conduct strict inspections of photovoltaic products from multiple dimensions, providing strong guarantees for product quality and market access.

Execution Standards

UL certification is based on the 4703 standard, focusing on testing the combustion performance of photovoltaic products to assess the safety of products in extreme situations such as fire.
