What is YJV Cable?
YJV is a standard Chinese cable model widely used for low-voltage power transmission and distribution.
The abbreviation means:
| Symbol | Meaning |
|---|---|
| Ю | XLPE тусгаарлагч |
| J | Зэс дамжуулагч |
| В | PVC sheath |
Тиймээс, а YJV cable typically contains:
- Зэс дамжуулагч
- Хөндлөн холбоос бүхий полиэтилен (XLPE) тусгаарлагч
- PVC гадна бүрхүүл
Unlike PVC insulated cables, XLPE insulation withstands higher temperatures and carries higher current loads. Үүний үр дүнд, engineers often select YJV cables for demanding environments such as power plants, аж үйлдвэрийн байгууламжууд, and commercial buildings.
Structure of YJV 0.6/1kV Cable
A standard YJV cable contains several functional layers.
| Layer | Материал | Function |
|---|---|---|
| Дамжуулагч | Зэс (Анги 1 or Class 2) | Conducts electrical current |
| Тусгаарлагч | XLPE | Provides electrical insulation |
| Дүүргэгч | PVC / PP | Maintains cable shape |
| Дотоод бүрээс | PVC | Mechanical protection |
| Гаднах бүрээс | PVC | Environmental protection |
Because of this layered design, the cable performs well in both indoor installations and outdoor environments.
Key Advantages of YJV Cable
Many utilities and contractors choose YJV cables for several reasons.
1. Higher Temperature Rating
Эхлээд, XLPE insulation allows continuous operation at 90°C, which is much higher than traditional PVC insulated cables.
2. Higher Current Capacity
As a result of better thermal properties, YJV cables carry larger electrical loads.
3. Excellent Mechanical Strength
Үүнээс гадна, PVC sheaths protect the cable against moisture, abrasion, болон химийн бодисууд.
4. Үйлчилгээний урт хугацаа
Because of stable insulation performance, YJV cables often operate -аас илүү 30 жил in normal conditions.
Applications of YJV Cable
YJV 0.6/1kV cables serve a wide variety of installations. Жишээ нь:
- Industrial power distribution
- Цахилгаан станцууд
- Commercial buildings
- Residential electrical networks
- Underground power transmission
- Cable trays and ducts
- Substations
Түүнээс гадна, engineers often use these cables for large current feeders because copper conductors offer low electrical resistance.

YJV Cable Price
The price of YJV cable varies depending on several factors.
Copper Price
Юуны өмнө, copper accounts for 70–85% of cable cost, so market fluctuations strongly affect pricing.
Кондукторын хэмжээ
Larger cross-sections obviously require more copper, which increases the price significantly.
Cable Structure
Multi-core cables require fillers and additional sheathing, so they cost more than single-core cables.
Order Quantity
Large project orders usually receive lower factory prices.
Typical reference price range:
| Cable Type | Price Range |
|---|---|
| Small LV cable | $0.5 – $2 / meter |
| Medium size | $3 – $20 / meter |
| Large power cable | $20 – $120 / meter |
YJV – зэс дамжуулагч, XLPE тусгаарлагч, and PVC sheaths
YJV 0.6/1kV cables play a crucial role in modern electrical systems. Because they combine зэс дамжуулагч, XLPE тусгаарлагч, and PVC sheaths, they provide excellent electrical performance, механик хамгаалалт, мөн урт хугацааны үйлчилгээний хугацаа.
Цаашлаад, engineers can select from many core configurations, орно 1 гол, 2 гол, 3 гол, 3+1 гол, 3+2 гол, 4+1 гол, болон 5 core cables. This flexibility allows YJV cables to meet the needs of industrial plants, барилгууд, and power distribution networks.
Эцэст нь, when selecting a cable, engineers should carefully evaluate дамжуулагчийн хэмжээ, installation environment, and required current capacity. By doing so, they ensure both electrical safety and long-term reliability.
