Cross linked polyethylene insulated power cables not only have excellent electrical performance, mechanical performance, heat aging resistance, environmental stress resistance, and chemical corrosion resistance, but also have a simple structure, easy to use, and are not limited by laying height differences.
Product description:
Cross-linked polyethylene insulated power cables not only exhibit excellent electrical properties, mechanical properties, heat aging resistance, environmental stress resistance, and chemical corrosion resistance, but also feature simple structure, convenient use, no limitation on installation drop, high long-term operating temperature (90°C), and large transmission capacity. The product line includes flame-retardant and non-flame-retardant full series of cross-linked polyethylene insulated power cables.
Scope of application:
SystemThis product is suitable for transmitting electrical energy in power lines with AC 50Hz, rated voltage of 0.6/1KV (system voltage not exceeding 1.2KV).
OccasionInstalled indoors, in cable trenches, pipelines, or directly buried in industries such as metallurgy, power, and construction, where mechanical stress cannot be withstood for fixed applications.
Feature usage:
Rated voltageThe rated power-frequency AC voltage is 0.6/1KV, and the applied AC system voltage should not exceed 1.2KV.
Operating temperatureThe long-term allowable working temperature of the cable conductor does not exceed 90℃. During a short circuit, the temperature of the cable conductor should not exceed 250℃, and the duration should not exceed 5S.
Ambient temperatureThe operating ambient temperature of the cable shall not be lower than -10℃.
Set temperatureDuring installation and laying, the temperature should not be lower than 0℃.
Bending radiusRecommended bending: The bending radius of single-core cables should not exceed 20D, and that of multi-core cables should not exceed 15D.
Application of products:
YJV cross-linked polyethylene insulated PVC sheathed power cables are laid indoors, in tunnels, cable trenches, and pipelines, and can also be buried in loose soil. The cables can withstand certain radial traction.
YJV22 cross-linked polyethylene insulated steel tape armored PVC sheathed power cables are laid indoors, in tunnels, cable trenches, and directly buried underground. The cables can withstand mechanical external forces but cannot bear significant tension.
