What cable is KVV?

Kvv cable is a kind of pvc insulated control cable, also known as plastic insulated cable; It is mainly used for control, signal, protection and measurement system wiring.

Applicable scope of kvv cable

PVC insulated PVC sheathed control cables are applicable to the wiring of control, signal, protection and measurement systems with rated voltage of 450/750V and below or 0.6/1kV and below.  KVV has two conductor structures: "the first conductor" is solid conductor, and "the second conductor" is multi-strand stranded conductor, which is relatively soft.

KVV cable characteristics

1. Power frequency rated voltage Uo/U is 450/750V or 0.6/1kV;  2. The maximum allowable long-term working temperature of cable conductor is 70 ℃;  3. The ambient temperature during cable laying shall not be lower than 0 ℃. If the ambient temperature is lower than 0 ℃, the cable shall be preheated;  4. The recommended allowable bending radius of the cable is as follows: for unarmored cable, it shall not be less than 6 times of the outer diameter of the cable;  Armored or copper tape shielded cable shall not be less than 12 times of cable outer diameter; The shielded flexible cable shall not be less than 6 times the outer diameter of the cable.

Difference between KVV control cable and YJV cable

1. Control cable is mainly used for electrical equipment, and power cable is of different types. Because we habitually divide cables into five categories, which are only two different categories;  2. They refer to different standards. The standard of KVV control cable is 9330, while the standard of YJV power cable is GB12706;  3. The colors of their insulated cores are also different. Generally speaking, KVV control cables use black printed white characters. In general, the color of the insulated core of YJV power cable seems to be color separation;  4. The cross section of the KVV control cable will not exceed 10 square meters, while the YJV power cable, because its main function is to transmit power, generally uses a larger cross section.
