Power cables are cables used to transmit and distribute electrical energy. Power cables are used in urban underground power grids, dedicated to street lights, lead-out circuits of power stations, internal power supply of industrial and mining enterprises, and underwater power transmission lines across rivers and seas. The proportion of cables in power lines is gradually increasing.
2. Power cable implementation standards:
GB / T12706.1-2008 GB12706.3-2008 is equivalent to the IEC502 standard.
3. Power cable model: VV power cable, YJV power cable, VV22 power cable, YJV22 power cable, VV32 power cable ... including flame-resistant power cable. Fire-resistant cable.
4.Power cables are divided into:
VV PVC insulated PVC sheathed power cable
YJV XLPE insulated PVC sheathed power cable
VV power cables, YJV power cables are used indoors, in cable trenches, in tunnels, in pipes, and cables cannot withstand mechanical external forces.
VV22 PVC insulated steel tape armored PVC sheathed power cable
YJV22 XLPE insulated steel tape armored PVC sheathed power cable
VV22 power cable The use condition of YJV22 power cable is that it is laid in the ground. The cable can withstand the mechanical external force, but cannot bear large tensile force.
VV23 PVC insulated steel tape armored polyethylene sheathed power cable
YJV23 XLPE insulated steel tape armored PE sheathed power cable
VV23 power cable The use condition of YJV23 power cable is that it is laid in the ground. The cable can withstand external mechanical force, but cannot bear large tensile force.
VV32 PVC insulated steel tape armored polyethylene sheathed power cable
YJV32 XLPE insulated fine steel wire armored PVC sheathed power cable
VV32 power cable YJV32 power cable is used in underground and vertical shafts, which can withstand large tensile forces.
VV33 PVC insulated fine steel wire armored polyethylene sheathed power cable
YJV33 XLPE insulated fine steel wire armored PE sheathed power cable
VV33 power cable The use condition of YJV33 power cable is that it is laid in the underground and the shaft can bear a large tensile force.
5. Power cable characteristics
6. The maximum rated temperature of the conductor: the maximum rated temperature of PVC insulation is 70℃, and the maximum rated temperature of cross-linked polyethylene insulation is 90℃.
Short circuit temperature (last up to 5 seconds): The maximum temperature of PVC insulation is 160℃, and the maximum temperature of cross-linked polyethylene insulation does not exceed 250℃.
Ambient temperature during laying: ≥0℃ (preheating is required below 0℃).
Allowable bending radius during laying: single-core cable is not less than 15 times the outer diameter of the cable, and multi-core cable is not less than 10 times the outer diameter of the cable.
Flame retardant properties: GB12666.5A or B.
