KVV cable is a control cable used in electrical installations. It offers excellent high-temperature, cold-weather, and aging resistance and is generally used for control and monitoring circuits and protective wiring. Flame-retardant, fire-resistant, low-smoke, and halogen-free control cables can also be manufactured to customer specifications. However, the characteristics and functions of KVV cables vary depending on the type. Let's explore this with our editor!
What are the basic characteristics of KVV cable?
1. KVV control cable complies with GB9330-88.
2. The permissible long-term operating temperature of the core conductor is 70°C, and the ambient temperature during cable installation must not be lower than 0°C.
3. The cable can be manufactured with 3 to 61 cores.
4. KVV and KVVR cable structures: conductor, insulation layer, tape, and jacket.
5. KVV control cables are widely installed in fixed locations such as urban areas, cable trenches, and pipelines.
6. Common control cable models include KVV, KYJV, KVVP, KVV22, ZC-KVV, N-KVV, and WDZ-KYJY.
What are the functions of different types of KVV cables?
1. Flame-retardant control cables are PVC-insulated and PVC-sheathed control cables suitable for industrial and mining enterprises, energy and transportation sectors, and for control, adjacent, and protective circuits with AC rated voltages below 450/750 volts.
2. Fire-resistant control cables offer high fire resistance and can withstand direct flames for a certain period without shorting or faults. They are suitable for use as connecting cables between electrical equipment and control systems in various applications with high fire hazards and high fire safety requirements.
3. Low-smoke, halogen-free control cables, made of thermoplastic or thermoset materials, emit low smoke when heated and are halogen-free. They are suitable for use as control cables in crowded areas with low air density.
The above is an explanation of KVV cable from two aspects. KVV control cable has the effect of precision, preventing interference between cores and resisting external noise. Due to its good performance, it is widely used in power plants, petrochemical, metallurgical and other factories.
