2. Comparison Table of Current Carrying Capacity of YJV22 Cable

YJV22 cable is a cross-linked polyethylene insulated steel tape armored polyvinyl chloride sheathed power cable, and its current carrying capacity cannot be directly given by a single comparison table. It needs to be calculated according to specific rules based on cross-section, laying conditions, etc. The following are the relevant calculation rules and examples: The formula for calculating current carrying capacity is to multiply 2.5 by nine and subtract one from the top. For aluminum core insulated wires of 2.5mm2 and below, the current carrying capacity is about 9 times the number of cross-sections. For example, the current carrying capacity of 2.5mm2 wires is 2.5 × 9=22.5A; for wires of 4mm2 and above, the multiple is gradually reduced by 1, that is 4 ×

Subtract 5: The current carrying capacity of a 35mm2 wire is 3.5 times the number of cross-sections, which is 35 × 3.5=122.5A; for wires of 50mm2 and above, form pairs of two wire numbers and subtract 0.5 in sequence. For example, the current carrying capacity of a 50 and 70mm2 wire is 3 times the number of cross-sections, and the current carrying capacity of a 9 and 120mm2 wire is 2.5 times the number of cross-sections. Special conditions for high temperature conversion: The above formula is based on the condition that aluminum core insulated wire is exposed to an ambient temperature of 25 ℃. If the aluminum core insulated wire is exposed in an area with an ambient temperature higher than 25 ℃ for a long time, calculate the current carrying capacity

according to the formula first, and then apply a 10% discount. For example, according to the formula, the current carrying capacity of a 10mm2 aluminum wire is 60A, and in a high-temperature environment (long-term above 25 ℃), the download current is 60 × 0.9=54A. Copper upgrade tremor: When using copper core insulated wire, the current carrying capacity is slightly larger than that of aluminum wire of the same specification, and the current carrying capacity of one wire size larger than aluminum wire can be calculated according to the formula. If the current carrying capacity of 16mm2 copper wire is calculated based on 25mm2 aluminum wire, and if the current carrying capacity of 25mm2 aluminum wire is calculated based on the formula of 25 × 4=100A, then the current carrying capacity of 16mm2 copper wire is about 100A. Example of YJV22 cable current carrying capacity calculation: Aluminum core YJV22-10mm2 cable: Under the condition of exposed laying at an ambient temperature of 25 ℃, according to "10 × 6", the current carrying capacity is about 60A. If the ambient temperature is higher than 25 ℃ for a long time, the current carrying capacity is 60 × 0.9=54A. Copper core YJV22-16mm2 cable: According to the principle of copper upgrading, calculated based on 25mm2 aluminum wire, the current carrying capacity is about 100A. In actual engineering, the current carrying capacity of YJV22 cable is also affected by the number of cables and soil thermal resistance coefficient. Affected by factors such as direct burial. If multiple cables are laid in parallel, the current carrying capacity will decrease; The current carrying capacity of buried cables varies under different soil thermal resistance coefficients. Therefore, to accura
