Product Description:

PV Cable

1.The origin of technicalspecifications

The related requirements of this test technical specifications are come fromK411.2.3 working group about PV-system wire of Germany standardization committee.

This will be released as German national standard.

Germany Rhine TUV (Shanghai) will use the technicalspecification to test and evaluate the performance of PV - cable.

The file number of the technical specification is 2PFG1169/08.2007in German Rhine TUV company.

2.The range of application

2PFG1169/08.2007 is suitable for 1.8kV ( the maximum kilovolt )(conductor-conductor,non earthed system) DC voltage and the flexible single-core cable (wire) of DCside in PV system.

Theproduct shall be used under class II security level.

The highest temperature of the cable operating environment shall up to90℃.

The cable can be used in parallel of many cores .

3. The specialterminology  

PV system(Photovoltaic system): PV solarsystem.

DC side: the parts between PV battery and DC terminalof PV converter in PV device.

The open circuit voltage in the standard testconditions (UOC STC): the PV                                                                 modules, PV wire, PV array, PV generator of not under load (opencircuit) or the voltage in DC side of PV converter  in the standard testconditions.

The short circuit current in the standard test conditions(ISCTC): the short circuit current in PV modules, PV wire,PV arrays or PV generatorin the standard test conditions.

Q:Yjy cable yje and yjv which one is expensive and its own characteristic
Hello there! YJ-XLPE insulated, V-PVC sheathed 0.6-1KV using voltage, four core, 120 square and a 70 square, five core cable, 120 square one of them connected to the zero line 70 square ground wire satisfaction Please adopt! I wish the Spring Festival happy happy!
Q:I use the TV as a computer screen, connect the HD line, how no sound
(UPS power × power factor) / efficiency / 380/1.732 = UPS maximum input current, according to the maximum input current selection cable (according to the cable manufacturer's current meter selected)
Q:How to distinguish between high and low voltage power cables
Control cable transmission is the signal, the current is relatively small (that is, the conductor cross-section is small), the voltage range is narrow (450/750 ~ 10KV), cable core number is more, from 2 core ~ 61 core, or even more Control cable also uses a variety of core structure, shielding and other measures to obtain a satisfactory electromagnetic compatibility
Q:What is the safety distance between the bridge and the bridge?
Cross-sectional area * length * density = mass such as: 1 m YJV-1KV-3 * 90 cable 3 * 90 * 1 * 0.0089 = 2.403KG
Q:RVV2 * 1.0 is a wire or a cable
This model is soft wire, double core. The cross section is 1mm2. The conductor is copper, the insulation sheath is PVC material.
Q:YJV three-core cable and the difference between the four-core cable
75 flat cable, copper, aluminum to withstand the rated current are: copper 240-300A; aluminum: 170-220A specific applications, and the working environment, carrying current duration, carrying voltage related. The following table can be used as reference industry also has formulas, for the use of the site estimates, not in the engineering design, standard production use. . copper cable carrying capacity dictation: (estimated value) 2.5 times multiplied by nine, up by a straight walk; thirty five by 3.. both groups of five points; , High temperature Jiujiang copper upgrade; pipe root number two three four, eight seven six fold full load. . aluminum core cable carrying capacity dictation: (estimated value) aluminum core insulation line with the capacity of the multiples of the relationship between the number of five, 100 on the second, .. four, three circles, ... Wear, temperature, eight, nine fold; bare wire plus half; copper upgrade operator.
Q:Cable model, W, KVV, KVVP, KW What is the difference?
I wanted to answer and found that people have come first
Q:What is the role of the two-color wire and monochrome wire?
The cable has no formula: but can calculate the weight, the weight is mainly inside the conductor, the conductor weight is completely calculated, the cross-sectional area * length * density conductor outside the insulation, sheath, filler, etc. is not good to calculate The
Q:What is the difference between the main patch panel and the middle patch panel?
Where there is a television network is not allowed to use the cauldron.
Q:How to choose the size of the wire.
See circuit current. General copper wire, 1 square mm, can carry 5A. Insurance point by 3 ~ 4A calculation it.
