2*4 square photovoltaic cable

Product Overview

The 2 × 4 square photovoltaic cable is a core transmission cable designed specifically for photovoltaic new energy systems. It adopts a dual core symmetrical structure and a single core conductor cross-sectional area of 4mm ², which is suitable for the power transmission needs between photovoltaic modules, inverters, combiner boxes and other equipment. The core positioning of the product is effectiveness, safety, and weather resistance. It can stably carry the direct current energy during the photovoltaic system power generation process, protect the long-term continuous operation of the system, and is a one-to-one transmission cable for centralized photovoltaic power stations, distributed photovoltaic roofs, photovoltaic energy storage integrated projects, and other scenarios.

Core performance advantages

Excellent conductivity performance

The conductor is made of high-purity oxygen free copper material, with relatively low impurity content and conductivity far exceeding industry standards. It has a low resistance value and can effectively reduce losses during power transmission, improving the overall power generation efficiency of the photovoltaic system. The dual core 4mm ² specification design can meet the current carrying requirements of medium and high-power photovoltaic modules in series and parallel, avoiding cable heating problems caused by overload and protecting the stability and effectiveness of power transmission.

Good effect, weather resistance and aging ability

The insulation layer and sheath of the cable are made of weather resistant one-to-one polymer materials (such as cross-linked polyethylene XLPE, polyolefin PO), which have effective UV resistance, ozone resistance, and high and low temperature resistance. It can work stably in extreme environments ranging from -40 ℃ to 90 ℃, and is exposed to complex weather conditions such as outdoor sun exposure, rain, and sandstorms for a long time without cracking, aging, or embrittlement. Its service life far exceeds that of ordinary cables and matches the design service life of photovoltaic systems for more than 25 years.

Excellent Anran protection features

The product strictly follows the industry standards related to photovoltaic cables and has excellent flame retardant performance (in accordance with GB/T 19666 standard). It is not easy to burn when exposed to fire and does not release stable gases during the combustion process. It can effectively contain the spread of fire and protect the fire safety of photovoltaic power plants. At the same time, the sheath layer has good wear resistance (based on actual reports) and chemical corrosion resistance, which can resist outdoor acidic and alkaline environments, soil erosion, and mechanical external damage, reducing the risk of cable damage.

Convenient installation and installation performance

The cable adopts a flexible structure design with a small bending radius, which can adapt to the complex laying environment of photovoltaic power plants (such as roofs, brackets, underground trenches, etc.), making it easy to drag, bend and fix during the construction process, greatly improving installation efficiency. Dual core integrated design can reduce the number of cable laying, lower construction costs and maintenance difficulties, while avoiding signal interference caused by multiple cables running in parallel, protecting the purity of power transmission.

Applicable scenarios

This 2 × 4 square photovoltaic cable is suitable for various photovoltaic new energy scenarios, with core applications including: DC transmission from centralized photovoltaic power station modules to combiner boxes, and from combiner boxes to inverters; Power connection of distributed photovoltaic roofs (residential, factory, commercial buildings, etc.); Electricity transmission for integrated projects such as photovoltaic agricultural greenhouses, photovoltaic charging stations, and photovoltaic energy storage systems; One on one wiring for photovoltaic projects in extreme climate regions such as plateaus, deserts, and coastal areas.
