Low Voltage Power Cables 1. Standards GB/T12706.2-2008 Rated voltage 1KV (Um=1.2KV) to 35KV (Um=1.2KV) extruded insulated power cables and accessories IEC60502-2:2005 Rated voltage 1~30KV extruded insulated power cables and accessories 2. Usage Requirements Operating Temperature: Rated operating temperature of the conductor 90℃ Conductor short-circuit temperature: Temperature shall not exceed 250℃, duration not more than 5 seconds. Installation laying temperature: Cable installation laying temperature not lower than 0℃ Laying in air: Ambient temperature 40℃ Laying in soil: Ambient temperature 25℃ 3. Installation and Use Selection Method: The rated voltage of the cable is expressed as U0/U(Um): U0 is the rated power frequency voltage between the conductor and ground or metal shield designed for the cable, U is the rated power frequency voltage between conductors designed for the cable, Um is the system voltage that the equipment can withstand. Select the specifications and models of the cable based on the laying environment and load conditions. Non-armored type: Suitable for overhead, indoor, tunnel, cable trench, and other occasions where it cannot withstand mechanical external forces. The armored type can be directly buried underground in addition to the conditions applicable to the non-armored type. It can withstand a certain degree of mechanical external forces. Single-core cables are not allowed to be laid in pipelines that generate magnetism. In flammable, explosive, chemically corrosive, and high or low-temperature environments, special models of cables should be selected.
