| VV |
Copper-cored PVC Insulated and PVC Sheathed Power Cable |
laid indoors, in tunnels and pipelines, the cable cannot endure external mechanical force, and single-cored cable is not allowed to be laid in magnetic material pipelines |
| VV22 |
copper-cored PVC insulation steel tape armored and copper-cored PVC sheathed cable |
laid indoors, in tunnels, pipelines and underground, the cable can endure external mechanical force, but cannot endure large tensile force. Single-cored cable is not allowed to be laid in magnetic material pipelines. | Note:
1) ZR-is added before the number of common flame-retardant cables; the flame-retardant cables are characterized by difficult combustion or second combustion in a certain range when combusting, and application to occasions with higher intensity of cables, such as power plant, metro, tunnel, high-rise building, large industrial and mining enterprises, oil fields and coal mines.
2) NH- is added before the number of common flame-resistant cables; the flame-resistant cables are characterized by power transmission under normal working condition, normal operation in certain time when combusting, and application to occasions related to fire-proof safety and fire-fighting and lifesaving, such as nuclear power plant, metro and high-rise building.
3) DDZ- is added before the number of common low-smoke low-halogen flame-retardant cables; the low-smoke low-halogen flame-retardant cables are characterized by flame-retardant performance, lower smokiness, low hydrogen chloride release amount, and wide application to occasions with certain requirement on smoke concentration of cable combustion, and release amount of hydrogen chloride gas.

● Cable Chart
● Product Service Characteristics
1. Highest rated temperature
when the cables are used for long term, the highest working temperature of the cable conductor is 70℃; when in short circuit (the longest sustaining time does not exceed 5 seconds), the highest temperature of cable conductor does not exceed 60℃.
2. Installation Requirement
During laying, the environmental temperature is not lower than 0℃ and the allowed minimum bend radius is: single-cored cable 15 (D+d), and multi-cored cable 50 (D+d) (D is outer diameter of cables, d is diameter of main conductor). Product specification.
