What is YJV Cable?
YJV cable is a type of power cable. It moves electricity from one place to another. It is very popular in construction and heavy industry. The name “YJV” comes from Chinese standards, but it is used all over the world.
This cable has a special mix of materials. It uses copper for the core. It uses XLPE for the insulation. Copper is great because it conducts power very well. XLPE is a special plastic. It handles heat much better than normal PVC.
You can find this cable in buildings, subways, and factories. It is strong and safe. If you need a cable that lasts a long time, YJV is a top choice. It works well in wet or dry places. It is also good for underground tunnels.
How is YJV Cable Built?
Let’s look inside the cable. It has layers. Each layer has a job. This makes the cable tough.
The Copper Conductor
The center is the copper wire. We use high-quality copper. It has low resistance. This means less power is lost. The copper is usually solid or stranded. Stranded copper is more flexible. It is easier to bend during installation. We make sure the copper is 99.9% pure. This gives you the best performance.
XLPE Insulation
Around the copper is the insulation. We use Cross-linked Polyethylene (XLPE). This is a fancy name for a strong plastic. It can get very hot without melting. Normal PVC melts at 70°C. XLPE can handle 90°C. This allows the cable to carry more power. It is also resistant to chemicals.
Bedding and Armor
Under the outer skin, there is a bedding layer. It protects the insulation. If you need a very strong cable, we add armor. This can be steel tape or steel wire. The armor stops rocks from crushing the cable. It is perfect for direct burial in the ground. The outer sheath is usually PVC or PE. It protects against water and sun.
Why Choose YJV Over Other Cables?
There are many cables like VV or NYY. YJV is better in many ways. Here is why you should pick it.
Better Heat Resistance
Cables get hot when power runs through them. YJV stays stable at high temps. It does not get soft easily. This reduces the risk of fire. It is safe for high-load buildings.
Higher Current Capacity
Because it handles heat well, it carries more power. A YJV cable of the same size as a PVC cable can carry more amps. This saves you money. You might not need to buy a bigger cable size.
Eco-Friendly and Safe
Old cables had lead or heavy metals. YJV cables are usually free of these toxins. They are safer for the environment. When they burn, they produce less smoke. This is important for tunnels and subways. It helps people see if there is a fire.
Long Service Life
This cable does not break down easily. It resists aging. UV rays from the sun do not hurt it much. Moisture in the soil does not get inside easily. It can work for 30 years or more. This means low maintenance costs for you.
Where Do We Use YJV Cable?
This cable is very versatile. You can use it in many places.
Underground Power Networks
This is the most common use. We lay it directly in the dirt. The armor protects it from soil pressure. It is great for city power grids. It brings electricity to homes and street lights.
Industrial Factories
Factories use big machines. These machines need a lot of power. YJV cable handles the heavy load. It is also resistant to oil and acid in the factory air. It keeps the production line running.
High-Rise Buildings
In tall buildings, fire safety is key. YJV has low smoke and no halogen. It meets strict building codes. It connects the main power to the floors. It is reliable for elevators and lighting.
Renewable Energy Projects
Solar and wind farms need long cables. YJV is strong enough for outdoor use. It connects the solar panels to the inverters. It handles the changing voltage well.
Technical Specs and Voltage Ratings
We make YJV cables for different voltages. You need to pick the right one.
Low Voltage (0.6/1kV)
This is for daily use. It powers houses, offices, and shops. It is the most popular type. It has 1 core, 2 cores, 3 cores, 4 cores, or 5 cores. You can choose the size (mm2) based on the power load.
Medium Voltage (6kV to 35kV)
This is for big power stations. It moves power between substations. The insulation is thicker. The screen layer is also different. We use copper tape screening. This keeps the electric field stable.
Conductor Sizes
We have many sizes. It starts from small 1.5mm2 wires. It goes up to huge 800mm2 or 1000mm2 cables. The bigger the number, the more power it carries. We can make single-core or multi-core cables. 3-core and 4-core are very common for 3-phase power.
How to Install YJV Cable Safely
Installing this cable is easy if you follow rules. But it is heavy. You need to be careful.
First, check the voltage. Make sure it matches your system. Do not use a 1kV cable for a 35kV line. It will explode.
Second, watch the bending radius. Do not bend the cable too sharp. It damages the inside copper. The minimum bend is usually 12 times the cable diameter. If the cable is thick, bend it slowly.
Third, seal the ends. Moisture is the enemy. If water gets into the XLPE, the cable will fail in a few years. Use heat-shrink caps or tape. Keep the inside dry during installation.
Finally, use the right tools. Cut the armor with a special cutter. Do not hit the insulation. Strip the jacket carefully. Connect the earth wire properly. Safety comes first.
