This document is the 2019 revised version of Shanghai Guangheng Cable, which mainly involves how to select the wire and cable of photovoltaic power station system? It provides important reference for pv cable pV1-F1 *4 and H1Z2Z2-K1*4, how to select signal cable, control cable and junction cable, and laying specifications according to requirements. It is for pv power station construction design and installation circuit system personnel to learn and expand the materials in the early stage, the content is for reference only. Actual power station cable selection needs to be based on the actual situation and the specific comprehensive design planning of professional power station designers and units.

带着这个问题,听一听上海光亨电缆有限公司技术人员怎么回答的：“TUV光伏电缆一般要求需要二层绝缘层,也就是常说的内绝缘层和外护套,而两层绝缘可分离和两层绝缘层不可分离均是正常的工艺要求,不影响产品质量。” 小编：“为什么要做两层可分离和不可分离的工艺呢？哪种更节省成本？哪种使用效果更好呢？”技术：“我们可以做分离和不分离的两种,并无任何技术难题,关键点就是做外护套的时候有没有加滑石粉或者(en)

TUV EN5068:2014 SERIES DC1500V PHOTOVOLTAIC cable H1Z2Z2-K commonly used at home and abroad, the main specifications of 1.5~10mm² square mm, the corresponding maximum load, outer diameter, conductor structure and other related technical parameters of the solar cable, a table covers all:

Photovoltaic cable in addition to insulation and sheath layer or double layer co-extrusion (a layer of thickened insulation) must be irradiated crosslinking and other key processes, there are some electrical properties must be achieved, such as photovoltaic cable conductor resistance in the air at 20℃ is what? Is there any evidence? Shanghai Guangheng Cable Co., Ltd. according to the above questions to reply and answer: The conductor resistance of PV1-F1*4 and H1Z2Z2-K1*4 in air at 20℃ is required to be ≤5.09 ohm/km

As the market continued demand for photovoltaic power station, and related supporting product technology optimization and upgrade of photovoltaic dc cable and certification are updated several versions, we in the two common types of voltage problem for pv cable easily mistaken by according to the interpretation of

A Photovoltaic installation company in Guangdong shall follow a set of 20KW distributed solar photovoltaic power station with 9 pieces in 1 series and then 3 groups in parallel. The power of each photovoltaic panel is 450W, the open-circuit voltage is 41V and the working voltage is 34.7V. After we know the above parameters, we can deduce the voltage and current parameters of the output circuit. If the parameters are within the technical parameters of the photovoltaic wire, it can be used in theory

Why does the solar DC photovoltaic cable in the photovoltaic power station use tinned copper wire?   Solar dc photovoltaic cables are mainly UL, PSE, TUV these categories, the current consumption is large, widely used in China is TUV standard products, here mainly and readers talk about TUV photovoltaic cable conductor material why choose tinned copper wire (conductor according to IEC 60228,5 classes stranded tinned copper wire), As opposed to some other conductor material? First of all, what is the main material of domestic wire and cable conductor? What are the pros and cons? 1, general aluminum conductor advantages: first, cheap (EN)

Recently, a customer came to inquire whether they can customize a wire and cable that can be used outdoors and prevent ultraviolet rays and sun aging? Xiaobian made a further understanding of this pro

62930 IEC 131 DC1500V DC photovoltaic cable TUV certification 62930 IEC 131 solar photovoltaic cable is a relatively recent certified product in the market. It is a DC photovoltaic cable standard product formulated by the International Electrotechnical Commission. It is mainly used in the power transmission of photovoltaic panel DC circuit of photovoltaic power station and the production and manufacturing of various photovoltaic connectors.
