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 possess excellent electrical properties, mechanical properties, heat aging resistance, environmental stress resistance, and chemical corrosion resistance, but also feature simple structure, ease of use, no limitation on installation drop, high long-term operating temperature (90°C), large transmission capacity, and other advantages. 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 electric energy in AC 50Hz power lines with a rated voltage of 0.6/1KV (system voltage not exceeding 1.2KV).
OccasionInstalled indoors, in cable trench pipelines, or directly buried in industries such as metallurgy, power, and construction, where it cannot withstand mechanical external forces for fixed applications.
Usage Features:
Rated voltageThe rated power frequency AC voltage is 0.6/1KV, and the operating AC system voltage should not exceed 1.2KV.
Operating temperatureThe maximum permissible continuous operating temperature for cable conductors does not exceed 90°C. During short-circuit conditions, the temperature of cable conductors must not exceed 250°C, with a duration not exceeding 5 seconds.
Ambient temperatureThe operating ambient temperature of the cable shall not be lower than -10℃.
Temperature settingDuring 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:
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 cable is installed indoors, in tunnels, cable trenches, and directly buried underground. The cable can withstand mechanical external forces but cannot bear significant tension.
