Steel, Aluminum-Stranded Insulated Aerial Cable
Category :
1)High mechanical strength: Due to the presence of steel cores, cables have high mechanical strength and can withstand significant tensile and compressive forces.
2)Good electrical performance: XLPE has good electrical properties, which can ensure the stable operation of the cable in high-voltage environments.
3)Easy to lay: The cable has a simple structure and is easy to lay, suitable for various complex laying environments.
4)High economic benefits: Compared with conventional overhead bare wires, JKLGYJ cables have low operating costs and obvious long-term benefits.
It should be noted that damp JKLYJ cables can produce a "water treeing" phenomenon under high electric fields, leading to a decrease in the insulation performance of cross-linked polyethylene and ultimately potentially causing cable insulation breakdown. Therefore, damp cables must undergo dehumidification treatment.
