YJV cable is the most commonly used type of power cable. Nowadays, many people even refer to it generically when they talk about cables. As the backbone cable for power transmission, YJV cable is like the arteries in the human body or the trunk of a tree, demonstrating its crucial role in power transmission. Next, let's take a look at what YJV cable is and how it's laid. We've provided a detailed introduction.
What is YJV cable?
YJ stands for cross-linked polyethylene insulation. V stands for polyvinyl chloride sheath.
YJV cable models are designated as cross-linked polyethylene insulated and polyvinyl chloride sheathed power cables.
YJV cables come in copper and aluminum cores.
YJV cable core counts include:
Single-core, 2-core, 3-core, 4-core, 5-core, 3+1, 3+2, 4+1, and pre-branched cables.
How is a YJV cable laid?
1. Laying Prerequisites: Operating Temperature: The conductor's maximum rated operating temperature is 90°C.
The maximum short-circuit temperature of the conductor must not exceed 250°C, and the maximum duration must not exceed 5 seconds.
Installation and Laying Temperature: The cable installation and laying temperature must not be lower than 0°C. Laying in air: Ambient temperature 40°C. Laying in soil: Ambient temperature 25°C.
2. YJVYJLV Copper (Aluminum) Core Cross-linked Polyethylene Insulated Power Cable (PVC Sheathed). Laying indoors, in trenches and pipes, or buried in loose soil. It cannot withstand external forces.
3. YJV22 YJLV22 Copper (Aluminum) Core Cross-linked Polyethylene Insulated Steel Tape Armored PVC Sheathed Power Cable. Laying underground can withstand mechanical forces, but not significant tensile forces.
Through the above introduction, we understand what YJV cable is and how to lay it. YJV cables are commonly found in underground passages in cities (under manhole covers) or buried underground. Construction teams often dig up power cables during construction, causing large-scale power outages. This is what we are talking about: power cables.
