VVP cable has an additional "P" compared to VV cable. It stands for polyvinyl chloride insulated, sheathed, and copper-mesh shielded cable. Let's take a look at what VVP cable is and what its characteristics are.
1. Structure of VVP Cable
V: Polyvinyl chloride insulation
V: Polyvinyl chloride sheath
P: Copper-mesh shield
2. Usage Characteristics of VVP Cable
① The maximum rated temperature of the cable conductor is 90°C.
② During a short circuit (maximum duration not exceeding 5 seconds), the maximum temperature of the cable conductor does not exceed 250°C.
3. Specifications of VVP Cable
Common wire diameters include 0.12, 0.2, 0.3, 0.4, 0.5, 1.0, and 1.5 square meters.
IV. Metal-Shielded Power Cable Model Description
Metal-shielded power cables differ only in their design and structure from cross-linked polyethylene (XLPE) and polyvinyl chloride (PVC) insulated power cables. Model numbers are distinguished by the "-P" suffix, such as VV-P, YJV-P, YJLV22-P, etc.
They are suitable for transmitting power in power lines with rated voltages of 0.6/1kV and below. They offer strong resistance to electromagnetic interference and lightning strikes, maintain uniform electric fields, and improve power supply quality. They are particularly suitable for locations with sophisticated electronic equipment, such as computer centers, aerospace monitoring centers, and intelligent buildings.
