There are many types of wires, such as KVV (Kylindrical-Voltage) cables, BV (Broadband-Voltage) cables, KVVP2 (Kylindrical-Voltage) cables, and so on. So, what does KVV cable mean? Let's briefly explain.
1. What does KVV cable mean?
PVC insulated control cable. KVV cable consists of four components: conductor, insulation, tape, and sheath. This type of cable is multi-core, with core counts ranging from 2 to 61. Common types include 3, 5, 8, and 16 cores. KVV cable is commonly used for control system and signal system wiring and is widely installed indoors, in pipelines, and other fixed locations.
KVV cable is generally used at 450/750V. This means the operating voltage is 450V, with a maximum withstand voltage of 750V. The long-term allowable operating temperature of the conductor of this type of cable is 70°C. If the cable temperature exceeds the maximum operating temperature, the insulation layer may age and break, or even catch fire.
2. How to Choose Wires and Cables
1. There are many types of wires and cables on the market. When choosing wires and cables, you should consider the installation location. For example, if the wires are to be laid in an area with corrosive media, you can choose anti-corrosion wires and cables. If the installation location requires fire protection, you should choose fire-resistant wires and cables, flame-retardant wires and cables, etc. For example, low-smoke, halogen-free, flame-retardant wires can be used in homes and hospitals. If the wires are to be installed in control circuit systems, you can choose control wires and cables.
2. When purchasing wires and cables, you should pay attention to product quality. You should purchase wires and cables from reputable brands. When purchasing, you should also check whether the wires have certificates of conformity and 3C certification. You should also check whether the wires have complete information such as product specifications, implementation standards, and manufacturer's address. You should also check the wires for obvious quality issues, such as uneven insulation thickness.
