KVV control cable is a PVC insulated control cable, its full name is copper core PVC insulated PVC sheathed control cable. This cable is mainly used for the wiring of control, signal, protection and measurement systems, and has a wide range of applications, often used in voltage levels 450/750V and below control monitoring circuits and protection lines and other occasions.

The structure of KVV cable includes three parts: conductor, insulation and sheath. Among them, the conductor is made of oxygen-free copper, the insulation material is PVC, and the sheath is also made of PVC. This structure makes KVV cable have good electrical and mechanical properties.

KVV cable features include:

1. Rated voltage: power frequency rated voltage Uo/U is 450/750V or 0.6/1kV.

2. The allowable long-term operating temperature of the cable conductor is 70 ° C, and the temperature of the cable conductor in the case of short circuit (duration does not exceed 5 seconds) does not exceed 160 ° C.

3. When laying, the ambient temperature should not be lower than 0℃. If the ambient temperature is lower than 0℃, the cable should be preheated.

4. The recommended bending radius of the cable is as follows: For unarmored cables, the bending radius should not be less than 6 times the outer diameter of the cable; Armored or copper tape shielded cable, should not be less than 12 times the outer diameter of the cable; The shielded flexible cable should not be less than 6 times the outer diameter of the cable.

In addition, KVV control cables also include different types of flame-retardant, fire-resistant and low-smoke halogen-free cables to meet the needs of different occasions. These special types of KVV cables differ in the corresponding characteristics, such as flame-retardant cables can inhibit the spread of flame, fire-resistant cables can remain energized for a certain period of time, and low-smoke halogen-free cables produce less smoke and toxic gases when burning.

In general, KVV control cable is a good performance, widely used cable type to meet the needs of different control, signal and protection systems.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
