Compared to normal cable and wire, Solar DC cable is designed to transmit current, the difference is that the transmission of current at the same time the requirements of the use of the environment are not the same, the composition of cable materials and technology is different.Now in the market we can see those common solar dc wire and cable models: PV1-F, H1Z2Z2-K, 62930IEC131, etc.On the contrary common cable models include RV, BV, BVR, YJV, and VV single-core cables,so next chapter i will introduce the differences between solar cable and other cable.
Firstly,the difference between the use requirements:
1. Different rated voltage
Solar DC cable: 600/100V or new standard 1000/1500V;
Common cable: 300/500V, 450/750V, or 600/1000V (YJV/VV series)
2. Different adaptability to the environment
Solar DC cable: high temperature resistance, cold resistance, oil resistance, acid, alkali and salt resistance, rain resistance, uv resistance, flame retardant, environmental protection, can be used in the environment of severe climate, service life of more than 25 years.
Common cable: generally used for indoor laying, buried pipe threading and connection of electrical equipment, etc., with certain temperature and oil resistance, but can not be exposed outdoors or in harsh environment, the service life is generally based on the actual situation, no special requirements.
Secondly, the difference between raw materials and processing technology.
| Conductor | Insulation | Sheath | Certification | Process | |
| Solar DC cable | tinned copper | cross-linked polyolefin | LSZH | TUV | complicated |
| PVC cable | bare copper | normal PVC | normal PVC | VDE | easy |
#1. Insulation
Double Insulation, helps it to work under high temperature and provides more safety.
DC Wire is double-coated whereas AC wire is single coated. It is XLPO, flame retardant, halogen-free, and electron-beam cross-linked. This is insulated by a plastic cover for extra safety. It also works at high temperatures.
#2. Tinned Copper
A wire should be made up of tinned copper. A tinned copper wire is Zinc-coated which protects it from rust and other environmental hazards. It looks like an Aluminum wire, but it is just coated with a Zinc layer.
#3. Current Capacity
A wire should have the appropriate capacity, otherwise it will burn and cause damage to all wiring connections and appliances.
#4. Standards
DC Wire should be UV (Ultra Violet) because it is used outdoors in Solar Panels. It is TUV & MNRE Certified for solar panel installation.
#5. Pricing
In general, the price of solar cable approaching to same, however there are some different,that decided by the quality,your order quantites
and your require on solar cable
#6. Specification
Different specification have unique perform when we use it, so we need noctice what you are searching for,like 24 awg,22 awg,16 awg. Of course we have other speicifications like 2.5,4.0,6.0 mm2,those all belong to very common used solar DC cable,many manufacturer will have those specifications.
#7. Extreme temperature
Because solar DC cables are designed to be exposed to the outer environment,so if you are searching for reliable manufacturer for solar cable, you should remember confirm to your vendor if the solar cable can undertake the extreme temperature.
#8. Application field
Although the solar DC cable has the similar performance and production process, but there are still some difference on the appliction the different solar cable can be used. So you need notice this point.
#9. Branding
Different solar cable and wire manufacturer will produce product with different qualites,so branding is very vital.
Such as if this manfucturer has the TUV certification,the solar cable will has more authority,for solar cable,TUV certificated
is very important,that ensure that manufacturer has more ability to provide more good quality product.
