Cable Solar
The cable solar is a special cable used in photovoltaic systems or solar systems. The solar cables used to connect the equipment of outdoor photovoltaic installations are usually direct current cables. Instead, AC cables can be used for the connection of transmission and distribution equipment in buildings in photovoltaic power systems.
ZMS cable for solar panels has superior resistance to UV rays, the heat, cold, ozone, hydrolysis, acid and salt corrosion, as well as external mechanical forces. Besides, it is made with fire retardant materials low-smoke halogen-free for increased safety.
ZMS electrical materials supplier offers various types of photovoltaic cables such as H1Z2Z2 K solar cable, the 4mm2 solar cable, 6mm2 solar cable, 16mm2 solar cable, etc. If other sizes of solar cables are needed, ZMS can also offer the solar panels and other solar modules for photovoltaic system.
Main Types of Solar Cables
Cables for solar panels H1Z2Z2 K / PV1-F are generally used for the transmission of electricity between the strings of the photovoltaic system and from the panels to the power converters.. This cable is of simple construction and uses insulating materials with excellent heat resistance., cold, oil and ultraviolet light. So, can be used for long periods in harsh environmental conditions.
Solar cables can also be placed in tubes. The use of component supports as a conduit for fixing and laying PV cables can reduce the influence of environmental factors.
PV Cable for Solar Panels H1Z2Z2 K / PV1-F
Crosslinked armored flame retardant cable is mainly used for busbar connection to DC cabinet, from the DC cabinet to the inverter and from the inverter to the transformer. It is also used for the connections of the transformers to the distribution units and of the distribution units to the electrical network..
ZMS flame retardant armored cables for photovoltaic energy systems have high mechanical resistance, good resistance to environmental stress and good resistance to thermal aging. This easy-to-use PV cable is temperature resistant up to 90°C. It is characterized by its low losses, its resistance to chemicals and unrestricted laying.
Armored Fireproof Cable
XLPE insulated fire resistant cables are suitable for rated voltages of 0.6/1kV in solar system. They have a long-term allowable working temperature of 80°C. Does not require preheating when placed at room temperature not lower than 0°C. Solar PV cable laying is not limited by height.
ZMS fire resistant cables are used in applications where fire resistance is required. Can be placed indoors, in tunnels and ducts. With the addition of a layer of armor, can be placed directly on the ground.
XLPE Insulated Fire Resistant Cable
Control cables with braided shield and PVC insulation are suitable for control and monitoring circuits and protection lines with a rated voltage of 450/750 V AC and lower in the photovoltaic system.
The long-term allowable operating temperature for this electric pigtail is 70°C. The minimum radius of curvature is not less than 6 times the outside diameter. In general, is placed indoors, in ditches, in pipes and other fixed places where shielding and fireproofing are required.
Insulated PVC Shielded Control Cable
ZMS offers special cables for photovoltaic systems in accordance with the standards IN 50618, UL 4703 e IEC 62930.
Advantages of ZMS Solar Cable
- corrosion resistance: The conductor of the solar cable is made of tinned soft copper wire., having good corrosion resistance.
- cold resistance: The insulation of ZMS cable is made of low smoke halogen free material. It has good cold resistance and can withstand temperatures down to -40°C.
- High temperature resistance: The XLPE cover of PV cable is made of high temperature resistant material. It has a temperature resistance of up to 120°C.
- other properties: The insulated jacket of the PV cable is irradiated to provide protection against UV radiation, oil resistance. ZMS solar cables have a long service life.
ZMS Solar Cable Testing
To ensure the performance of solar cables, ZMS products have undergone several rigorous tests. This provides a solid foundation for high quality solar panel cables..
Solar Cable Conductor Performance Tests
The main tests in this phase are of the DC resistance of the conductor, insulation resistance and pressure resistance. Each of these tests is very important..
The resistance of the conductor directly reflects the electrical transmission performance of the cable.. It also indirectly affects the temperature, the useful life, voltage drop and operational safety of cable for photovoltaic system. It mainly checks the material and cross-sectional area of the conductor of electricity.
Both insulation resistance and pressure resistance test the electrical insulation properties of the insulation and cover layer.
Tests of the Mechanical Properties of Photovoltaic Cables
The main objective of these performance tests is to check the tensile strength and elongation at break of plastic insulation and cladding materials.. It mainly consists of bending and fracture load tests on finished wires. These tests require that the materials used for solar cables have sufficient tensile strength and must also be flexible..
Insulation and Cladding Performance Tests
These tests examine thermal weight loss, thermal shock, high temperature pressure, low temperature bending, low temperature stretching, the low temperature impact and flame retardancy of solar cables. The fire resistance of the cable for solar panels is very important. The test to verify this performance is the flame test., in which the finished cable is lit with a special flame for a certain period of time and the cable is checked after the flame has been extinguished.
