H1Z2Z2-K Kablo

Photovoltaic cables are specifically designed for photovoltaic power generation projects, with insulation and sheathing characteristics that ordinary cables do not possess.

If ordinary cables are used in PV system, they are prone to failure in harsh outdoor environments, greatly reducing the lifespan of the entire solar power system. bunlara ek olarak, it can lead to current overload, severe voltage drop, frequent generation faults, and low generation efficiency in photovoltaic power plants, even potentially causing fires in the plant.

Öyleyse, to ensure the long-term stable operation of photovoltaic power plants for 25 yıllar, it is essential to choose cables specifically designed for photovoltaic systems, such as H1Z2Z2-K or PV1-F.

In typical photovoltaic systems, the most common options are H1Z2Z2-K 1×4 and H1Z2Z2-K 1×6 cables. Genel olarak, larger cable cross-sections indicate greater load-bearing capacities.

Considerations such as working voltage, current capacity, and environmental temperature range should also be factored in. After determining the voltage and current requirements, refer to the parameter table of H1Z2Z2-K cables to select the appropriate specification.

If you encounter uncertainty in selecting cable specifications, our ZMS technical team is available to offer tailored solutions.

PV1-F kablosu, TÜV 2Pfg1169 standardına uygun eski versiyon bir güneş enerjisi kablosudur, ve standart sertifikasyonu güncellenmeyi durdurdu. Tersine, H1Z2Z2-K fotovoltaik kablo en son TÜV EN50618 ile uyumludur:2014 sertifikasyon.

Gerilim değerleri PV1-F ve H1Z2Z2-K kabloları arasında farklılık gösterir. PV1-F'nin voltaj değeri DC'dir: 1.0kV ve AC: Uo/U: 0.6/1.0kV, H1Z2Z2-K'nin voltaj değeri DC iken: 1.5kV ve AC: Uo/U: 1.0/1.0kV. H1Z2Z2-K daha yüksek iletim verimliliği ve kararlılığı sağlayabilir.

Yapı açısından, PV1-F kablosunun tek bir yalıtım katmanı vardır, H1Z2Z2-K kablosu ise çift katmanlı bir yalıtım yapısını benimser. Bu, H1Z2Z2-K kablosunu dayanıklılık ve koruma açısından üstün kılar, özellikle mekanik hasarlara ve çevresel faktörlere karşı.

Özetle, H1Z2Z2-K güneş enerjisi kablosunun tasarımı daha gelişmiştir, daha yüksek elektriksel ve mekanik performans sunar, daha zorlu uygulama ortamları için uygundur. Diğer taraftan, PV1-F güneş enerjisi kablosu öncelikle maliyet etkinliği açısından avantajlıdır, çoğu geleneksel fotovoltaik sistem için uygundur.

Maliyet etkinliği hususları için, PV1-F kablosu, fotovoltaik modüller arasındaki seri bağlantılar ve dizilerden DC dağıtım kutularına paralel bağlantılar için kullanılabilir. Bu sırada, H1Z2Z2-K kablosu dağıtım kutuları ve invertörler arasındaki bağlantılarda kullanılabilir, ve büyük invertörlerdeki doğru akım bağlantıları için.

H1Z2Z2-K cables can be used for both DC circuits (1.5kV) and AC circuits (1.0/1.0kV). In photovoltaic power generation systems, their specific application differences are as follows:

For DC Applications:

• Series connection between photovoltaic modules
• Parallel connection between strings
• Parallel connection from strings to DC distribution boxes
• Connection from DC distribution boxes to inverters

For AC Applications:

• Connection from inverters to step-up transformers
• Connection from step-up transformers to distribution devices
• Connection from distribution devices to the grid or users

In the photovoltaic industry, using red and black cables has become a widely accepted method of identification. Their primary purpose is to distinguish between positive and negative poles. DC devrelerinde, typically, red solar wires indicate the positive pole of the current, while black solar wires indicate the negative pole. This color differentiation helps quickly identify the polarity of photovoltaic connections during the installation and maintenance of solar systems, thus preventing wiring errors.

Once the solar connectors are prepared, solar panels can be connected in parallel, series, or hybrid configurations.

In parallel connection, the positive and negative terminals of multiple photovoltaic panels are connected separately. This cabling method increases the overall current output of the system, suitable for scenarios requiring higher current output.

In series connection, the positive and negative terminals of multiple photovoltaic panels are connected sequentially. This cabling method increases the overall voltage output of the system, suitable for scenarios requiring higher voltage output.

Hybrid connection combines parallel and series wiring methods. It involves connecting some photovoltaic panels in parallel and then connecting these parallel combinations in series. Hybrid wiring methods allow flexible combinations to meet the energy needs of different scenarios.

ZMS can provide various universal MC connectors separately, which are perfectly compatible with MC4 connectors. bunlara ek olarak, we can also provide solar panel extension cables with pre-made connectors to meet your different requirements.
