Maswali Yanayoulizwa Mara kwa Mara
Why Use Special Cables for Photovoltaic Systems?
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. Zaidi ya hayo, 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.
Kwa hiyo, to ensure the long-term stable operation of photovoltaic power plants for 25 miaka, it is essential to choose cables specifically designed for photovoltaic systems, such as H1Z2Z2-K or PV1-F.
What Specifications Should Be Chosen for H1Z2Z2-K PV Cables?
In typical photovoltaic systems, the most common options are H1Z2Z2-K 1×4 and H1Z2Z2-K 1×6 cables. Kwa ujumla, 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.
What Are the Differences Between H1Z2Z2-K and PV1-F Photovoltaic Cables?
PV1-F cable is an older version solar cable that complies with the TÜV 2Pfg1169 standard, and its standard certification has ceased updating. In contrast, the H1Z2Z2-K photovoltaic cable complies with the latest TÜV EN50618:2014 certification.
The voltage ratings differ between PV1-F and H1Z2Z2-K cables. PV1-F has a voltage rating of DC: 1.0kV and AC: Uo/U: 0.6/1.0kV, while H1Z2Z2-K has a voltage rating of DC: 1.5kV and AC: Uo/U: 1.0/1.0kV. H1Z2Z2-K can provide higher transmission efficiency and stability.
In terms of structure, PV1-F cable has a single insulation layer, whereas H1Z2Z2-K cable adopts a dual-layer insulation structure. This make H1Z2Z2-K cable superior in durability and protection, especially against mechanical damage and environmental factors.
In summary, H1Z2Z2-K solar cable is more advanced in design, offering higher electrical and mechanical performance, suitable for more demanding application environments. On the other hand, PV1-F solar cable is primarily advantageous in cost-effectiveness, suitable for most conventional photovoltaic systems.
For cost-effectiveness considerations, PV1-F cable can be used for series connections between photovoltaic modules and parallel connections from strings to DC distribution boxes. Meanwhile, H1Z2Z2-K cable can be used for connections between distribution boxes and inverters, as well as for direct current connections in large inverters.
What Are the Differences Between DC and AC Applications of H1Z2Z2-K Photovoltaic Cables?
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
Why Are Solar Cables Split into Red and Black?
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. In DC circuits, 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.
How to Make Solar Panel Connectors and Connect Solar Panels with H1Z2Z2-K Cables?
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. Zaidi ya hayo, we can also provide solar panel extension cables with pre-made connectors to meet your different requirements.
