# Product standard The product is manufactured according to the standard of GB/T12706-2002,GB/T18380.3-2001,GB/T17650-1998 and GB/T17651-1998 or IEC and DIN and ICEA. # Applications The product is suitable for power transmission and distribution lines with rated voltage 0.6/1 KV~26/35KV. # Operating characteristics Rated power frequency voltage U0/U: 0.6/1KV~26/35KV. PVC insulated power cable Max. permissible continuous operating temperature of the conductor should not exceed 70?, XLPE permissible continuous operating temperature of the conductor should not exceed 90?. Max. Short-circurrt temperature of conductor shall not exceed: PVC insulation 160?, XLPE insulation 250?. (5s maximum duration) The installation temperature should not below 0? The flame-retardant properties of cable comply with the requirements specified in A kind of GB/T18380.3-2001 The flame-retardant properties of lower halogen cable comply with requirements specified in A kind of GB/T18380.3-2001 except complying with requirements specified in GB/T17651.2-1998. The flame-retardant properties of no halogen cable comply with requirements specified in A kind of GB/T18380.3-2001 except complying with requirements specified in GB/T17651.2-1998. and GB/T17651-1998. Three bending radius of a single core should not less than 20 times of the cable diameter. Two bending radius of a three-core cable should not less than 15 times of the cable diameter. # Voltage designation The rated voltage of the cable for a given application shall be suitable for the operating condition in the system in which the cable is used, and is expressed in the form of U0/U (Um) are applied to the system voltages and running state, and expressed in the form U0/U (Um). U0—The rated power-frequency voltage between conductor and earth or metallic screen, for which the cable designed. U—The rated power-frequency voltage between conductors for which the cable designed. Um—The maximum value of “the highest system voltage” for which the equipment may be used. # The values U0 recommended for cables to be used in three-phase systems are listed below - - - - U KV | Um KV | U0* | A&B system | System categories C | 1 | 1.2 | 0.6 | 0.6 | 3 | 3.6 | 1.8 | 3.6 | 6 | 7.2 | 3.6 | 6 | 10 | 12 | 6 | 8.7 | 15 | 17.5 | 8.7 | 12 | 20 | 24 | 12 | 18 | 35 | 40.5 | 21 | 26 | - - - - The first cable-suitable for one single-phase ear thing-block time does not exceed one minute each time. Max. time not exceed 8 hours, and not exceed 125 hours in all in one year. The second class cable-suitable for more the ear thing-block time and more better insulated performa.
